The Anonymous Widower

Could We See Between London And Much Of The North By Train In Under Two Hours?

I shall write about each route in order starting from Euston and working East.

Avanti West Coast And Euston

These are services from Euston, that I feel could be under two hours.

London Euston And Liverpool Lime Street

On Thursday, I went to Liverpool by train.

  • My train took two hours and thirteen minutes between London Euston and Liverpool Lime Street stations.
  • There were stops at Stafford, Crewe and Runcorn.
  • The Class 390 train was travelling at 125 mph for a lot of the way.
  • The distance between the two terminals is 193.6 miles.
  • The start to stop average including the stops was 87.3 mph.

So could London Euston and Liverpool Lime Street be achieved in the magic two hours?

A few thoughts.

Average Speed

To do the journey in this time  would need an average speed of 96.8 mph.

Accelerating And Stopping

Ideally, the train will run as fast as it can only changing speed for the station stops.

  • The train will accelerate from stop to cruising speed at Euston, Stafford, Crewe and Runcorn or four times.
  • The train will decelerate from cruising speed to stop at Stafford, Crewe, Runcorn and Liverpool Lime Street or four times.

Effectively, the train goes through four complete station stops, although one will be split between the two ends of the journey.

These figures are from Wikipedia and the Internet

  • The acceleration of the Class 390 train is 1.0 mph/sec which means that it takes 125 seconds to get to 125 mph.
  • The deceleration of a Class 390 train is 2.0 mph/sec, which means that it takes 63 seconds to stop from 125 mph.
  • The acceleration of a Class 801 train is 1.6 mph/sec which means that it takes 78 seconds to get to 125 mph.
  • The deceleration of a Class 801 train is 2.2 mph/sec, which means that it takes 57 seconds to stop from 125 mph.

These figures would appear to show, that a Class 801 train can decelerate and accelerate at a stop in nearly a minute faster than a Class 390 train.

So how can we increase the acceleration and deceleration? The two obvious ways are more power and less weight.

Form the Internet, I estimate that the average car in a Class 390 train is around 52 tonnes, as opposed to 41 tonnes for the Hitachi trains.

So does this weight difference explain some of the difference in acceleration and deceleration times?

Consider.

  • The Class 390 trains have all the extra weight of the tilt mechanism. More weight means slower acceleration.
  • Avanti West Coast’s new Class 807 trains have no diesel engines or batteries. Have the trains been put on a diet?
  • They also have a reprofiled nose. Is it more aerodynamic?

So if these trains can save time on the four accelerate/decelerate cycles compared to the Class 390 trains, they must be getting nearer to the magic two hours.

If two minutes a stop can be saved that would save eight minutes on the journey between London Euston and Liverpool Lime Street.

140 Mph Running

The time to do a mile at various speeds are as follows.

  • 100 mph – 36 seconds
  • 125 mph – 29 seconds
  • 140 mph – 26 seconds

So running at 140 mph, as opposed to the current 125 mph would save three seconds for every mile.

To save five minutes would mean the train would have to run for a hundred miles at 140 mph instead of 125 mph.

As Stafford is 133.5 miles from London, it could be that full digital signalling should be installed on the West Coast Main Line all the way to Stafford or even Crewe, which is 158 miles from London.

This schematic map of the West Coast Main Line was clipped from Wikipedia.

Note.

  1. Trains between London Euston and Liverpool Lime Street take the Trent Valley Line through Nuneaton and Lichfield Trent Valley and stop at Stafford, Crewe and Runcorn.
  2. Trains between London Euston and Manchester take a variety of routes and all go via Stockport.
  3. One train per hour (tph) between London Euston and Glasgow Central takes the Trent Valley Line and goes non-stop between London Euston and Warrington Central.
  4. Norton Bridge Junction just to the North of Stafford has recently been remodelled.

I believe there is potential to enable up to at least a hundred miles of 140 mph running to the South of Crewe. Especially as most of the track South of Crewe is quadruple track.

This should enable the shaving of five or more minutes off the time of any train capable of 140 mph running that uses the Trent Valley Line through Nuneaton, Lichfield Trent Valley and Stafford.

Norton Bridge Junction

Norton Bridge junction, which is five miles North  used to be a bottleneck, but it has now been remodelled.

I wrote about it in The New Norton Bridge Junction In Action.

The new junction has probably been designed so that it can save a few seconds for trains going between Stafford and Crewe, whether or not they stop at either or both stations.

Non-Stop Between London Euston and Runcorn

If you look at the times of a London Euston and Glasgow Central train via the Trent Valley Line , it travels the 174.7 miles between London Euston and Weaver Junction non-stop in one hour and forty minutes. This is an average speed of 104.8 mph.

By comparison, my train on Thursday took one hour and forty-seven minutes with the two stops at Stafford and Crewe.

So there is at least six minutes to be saved by going non-stop.

 

Two Trains Per Hour Between London Euston And Liverpool Lime Street

Wikipedia says this about an additional service.

Subject to approval by the Office of Rail and Road, an additional hourly service will be introduced between London Euston and Liverpool Lime Street with a stop at Liverpool South Parkway from December 2022.

I have a few thoughts and questions on extra services between London Euston and Liverpool Lime Street,

  • In my view the second service is much needed.
  • I also think, that a later train back to London is needed.
  • Does the Wikipedia statement mean that only one train will stop at Liverpool South Parkway?
  • Does Runcorn need two tph to and from London?
  • Would the platforms at Liverpool South Parkway be lengthened to accept eleven-car Class 390 trains?

I feel that if a train stopped at both Liverpool South Parkway and Runcorn, this would make a two-hour journey more difficult to achieve.

London Euston And Liverpool Lime Street In Two Hours

The new Class 807 trains will be delivered by 2022. Because of the pandemic, I’ll assume that of the ten trains on order, some, but not all, will be available by the December 2022 timetable change.

The time savings needed for a two-hour journey will come from four improvements.

  1. The increased performance of the Class 807 trains.
  2. Full digital signalling South of Crewe.
  3. The track improvements already completed like Norton Bridge Junction.
  4. Cutting out stop on the second service.

There may also be time savings to be obtained at the intermediate stops, by better working practices.

I doubt that the full digital signalling will have been installed, but all trains will be capable of 125 mph running.

Avanti West Coast probably have a good idea of the time they could achieve without digital signalling and I feel that they could be about five minutes over two hours with the Class 807 trains.

As the eleven-car Class 390 trains are too long for Liverpool South Parkway station, could we see the following service?

  • 1 tph – Class 390 train – London Euston And Liverpool Lime Street via Runcorn, Crewe and Stafford.
  • 1 tph – Class 807 train – London Euston And Liverpool Lime Street via Liverpool South Parkway.

Note.

  1. The Class 390 train would run the existing timetable in two hours and thirteen minutes.
  2. The Class 807 train would be a two-hour express service if possible.
  3. Going from three stops to one could save the express at least seven minutes, as I showed earlier by looking at train timings South of Weaver Junction.
  4. There would be time savings of at least two minutes on the express service due to the better performance of the Class 807 train.

To save the final four minutes, there would need to be at least eighty miles of 140 mph running, as each mile saves three seconds.

I am fairly certain, that London Euston and Liverpool Lime Street can be regularly achieved in two hours.

London Euston And Warrington Bank Quay

The hourly London Euston and Glasgow Central expresses seem to take one hour and forty-five minutes for the non-stop trip of 182.1 miles, which is an average speed of 104 mph.

As this service is non-stop, I believe that this service would get the maximum benefit from digital signalling and this service will only get faster, as more and more of the route allowed 140 mph-running.

I wouldn’t be surprised to see almost ten minutes lopped off this service by signalling and other improvements.

I am fairly certain, that London Euston and Warrington Bank Quay can be regularly achieved in well under two hours, by a Class 390 train.

London Euston And Wigan North Western

The hourly London Euston and Glasgow Central expresses seem to take one hour and fifty-six minutes for the single-stop trip of 193.9 miles, which is an average speed of 100.3 mph.

As this service just a single stop at Warrington Bank Quay, I believe that this service would get the maximum benefit from digital signalling and this service will only get faster, as more and more of the route allowed 140 mph-running.

As with Warrington Bank Quay, I wouldn’t be surprised to see almost ten minutes lopped off this service by signalling and other improvements.

I am fairly certain, that London Euston and Wigan North Western can be regularly achieved in comfortably under two hours, by a Class 390 train.

London Euston And Preston

The hourly London Euston and Glasgow Central expresses seem to take two hours and eleven minutes for the two -stop trip of 209 miles, which is an average speed of 95.7 mph.

As this service just stops at Warrington Bank Quay and Wigan North Western, I believe that this service would get the maximum benefit from digital signalling and this service will only get faster, as more and more of the route allowed 140 mph-running.

As with Warrington Bank Quay and Wigan North Western, I wouldn’t be surprised to see almost ten minutes lopped off this service by signalling and other improvements.

I am fairly certain, that London Euston and Preston can be regularly achieved in just under two hours, by a Class 390 train.

London Euston And Blackpool North

Avanti West Coast have indicated that their new Class 807 trains will run between London Euston and Blackpool North.

Consider.

  • I am fairly certain that a Class 390 train will be able to run between London Euston and Preston in under two hours, once digital signalling is installed South of Crewe.
  • Currently, Class 390 trains take twenty minutes between Preston and Blackpool North stations.
  • The Class 807 trains have better acceleration and deceleration and should be able to execute faster stops than the Class 390 trains.

I wonder if Avanti West Coast, Hitachi, Network Rail and Rock Rail have thought up a cunning plan to run Class 807  trains between  London Euston And Blackpool North, in under two hours.

Trains would go via the Trent Valley.

Trains might only stop at perhaps Milton Keynes Central, Warrington Bank Quay, Wigan North Western and Preston.

Trains would run at up to 140 mph using digital signalling, in as many places as possible.

Is the performance of the Class 807 trains sufficient to achieve London Euston and Blackpool North in under two hours via the Trent Valley?

London Euston And Manchester Piccadilly via Wilmslow

Consider.

  • Most trains between London Euston and Manchester Piccadilly via Wilmslow seem to take around six or seven minutes over two hours.
  • I believe that if the 158 miles between London Euston and Crewe were to be digitally signalled, then this could save up to eight minutes by allowing trains to run at 140 mph rather than the current 125 mph.

This could be enough to bring the London Euston and Manchester Piccadilly via Wilmslow below two hours.

I am not surprised at this, as the trains were built for 140 mph and because there is no digital signalling, they are limited to 125 mph, which slows the trains by six or seven minutes.

London Euston And Manchester Piccadilly via Stoke-on-Trent

Everything I said about trains between London Euston and Manchester Piccadilly via Wilmslow probably apply, except that the services via Stoke-on-Trent are a few minutes slower.

But I do feel, that this could be enough to bring the London Euston and Manchester Piccadilly via Stoke-on-Trent below two hours.

East Midlands Railway And St. Pancras

These is only one service from St. Pancras, that is not comfortably under two hours.

London St. Pancras And Sheffield

A typical service between London St. Pancras And Sheffield takes a few minutes over two hours..

  • There are two tph
  • There are stops at Leicester, Loughborough, East Midlands Parkway, Long Eaton, Derby or Chesterfield depending on the service.
  • The Class 222 trains travel at 125 mph for most of the way.
  • The distance between the two terminals is 164.7 miles.
  • The start to stop average including the stops is 81 mph.

I would suspect that East Midlands Railway’s new bi-mode Class 810 trains will be able to easily break the two-hour barrier.

  • They have four diesel engines so they can cruise at 125 mph on diesel.
  • They have electric power for South of Market Harborough.
  • Some diesel engines will be changed for batteries.

As electrification increases on the Midland Main Line, these trains will use less and less diesel.

I also suspect that digital signalling will start to creep into the route, starting from Bedford, where it is used on Thameslink.

LNER And King’s Cross

These are services from King’s Cross, that are or I feel will be under two hours.

London King’s Cross And Doncaster

A typical service between London King’s Cross And Doncaster takes around one hour and thirty-seven minutes.

  • There are four tph
  • There are stops at Stevenage, Peterborough, Grantham, Newark and Retford depending on the service.
  • The Class 80x trains travel at 125 mph for most of the way.
  • The distance between the two stations is 156 miles.
  • The start to stop average including the stops is 96.5 mph.

Digital signaling is being installed on this section of the East Coast Main Line and I suspect that this will reduce timings between London King’s Cross And Doncaster.

A simple estimate based on the maximum operating speed, indicates a time of one hour and twenty-six minutes should be possible.

But as a Control Engineer, I believe that digital signalling will lead to faster running over the Digswell Viaduct and through the flat crossing at Newark.

The timing will certainly be under one hour and thirty minutes between London King’s Cross And Doncaster.

London King’s Cross And York

A typical service between London King’s Cross And York takes around one hour and forty-eight minutes.

  • There are two tph
  • There are stops at Stevenage, Peterborough, Grantham, Newark, Retford and Doncaster depending on the service.
  • The Class 80x trains travel at 125 mph for most of the way.
  • The distance between the two stations is 188.5 miles.
  • A non-stop service takes one hour and fifty-two minutes, which is a start to stop average including the stops is 101 mph.

If my crude estimate of time savings because of digital signalling South of Doncaster can be applied, this would imply a reduction in journey time of at least eleven minutes.

London King’s Cross And Leeds

A typical service between London King’s Cross And Leeds takes around two hours and thirteen minutes.

  • There are three tph
  • There are stops at Stevenage, Peterborough, Grantham, Newark, Doncaster and Wakefield Westgate depending on the service.
  • The Class 80x trains travel at 125 mph for most of the way.
  • The distance between the two terminals is 185.9 miles.
  • This is a start to stop average including the stops is 83.9 mph.

If my crude estimate of time savings because of digital signalling South of Doncaster can be applied, this would imply a reduction in journey time of at least eleven minutes, which would put a time between London King’s Cross and Leeds of around two hours.

London King’s Cross And Bradford Forster Square

LNER run some services on this route

  • The services take thirty minutes between Leeds and Bradford Forster Square stations.
  • The services do not reverse at Leeds.

Given that two hours should be possible between London Kings Cross and Leeds, it would appear that two hours and thirty minutes should be possible between Leeds and Bradford Forster Square stations.

London King’s Cross And Bradford Interchange

Grand Central run some services on this route

  • The services call at Doncaster, Wakefield Kirkgate, Mirfield, Brighouse and Low Moor
  • The services take two hours and fifty-four minutes between London King’s Cross and Bradford Interchange stations.
  • The services take one hour and seventeen minutes between Doncaster and Bradford Interchange stations.

The services are run by Class 180 diesel trains, which will have to be replaced to decarbonise the route.

I suspect that Hitachi will have a train for this route, that could use diesel or batteries to the North of Doncaster.

  • My estimate for the best time between King’s Cross and Doncaster is one hour and twenty-six minutes.
  • The current time between Doncaster and Bradford Interchange stations is one hour and seventeen minutes.

This gives a best time of perhaps two hours and forty-three minutes between Doncaster and Bradford Interchange stations.

The route to Bradford via Leeds is perhaps fifteen minutes faster, but it serves different stations.

London King’s Cross And Harrogate

LNER has been running to Harrogate for some time.

  • There is one train per two hours (tp2h)
  • The service calls at Stevenage, Grantham, Doncaster, Wakefield Westgate and Leeds.
  • some services reverse at Leeds.
  • The service takes two hours and fifty-five minutes between London King’s Cross and Harrogate stations.
  • The service takes thirty minutes between Leeds and Harrogate stations.

Given that two hours should be possible between London Kings Cross and Leeds, it would appear that two hours and thirty minutes could be possible between London King’s Cross and Harrogate stations.

London King’s Cross And Huddersfield

In LNER Expands To Huddersfield, I described LNER’s new service to Huddersfield.

  • There will be one train per day (tpd)
  • The service will call at Peterborough, Newark North Gate, Doncaster, Wakefield Westgate, Leeds and Dewsbury.
  • The service will split and join with the London King’s Cross and Skipton service at Leeds.
  • The service will reverse at Leeds.
  • The service take two hours and fifty-five minutes between London King’s Cross and Huddersfield stations.
  • The service will take twenty-five minutes between Leeds and Huddersfield stations.
  • Improvements are planned, which include electrification, between Dewsbury and Huddersfield

Given that two hours should be possible between London Kings Cross and Leeds, it would appear that two hours and thirty minutes could be possible between London King’s Cross and Huddersfield stations.

London King’s Cross And Hull

The fastest Hull Trains service between London King’s Cross And Hull takes around two hours and thirty minutes.

  • There are seven tpd
  • There are stops at Stevenage, Grantham, Retford, Doncaster, Selby, Howden and Brough depending on the service.
  • The Class 80x trains travel at 125 mph for most of the way.
  • The distance between the two terminals is 205.3 miles.
  • This is a start to stop average including the stops is 82.1 mph.

If my crude estimate of time savings because of digital signalling South of Doncaster can be applied, this would imply a reduction in journey time of at least eleven minutes, which would put a time between London King’s Cross and Hull of around two hours and twenty minutes.

London King’s Cross And Middlesbrough

LNER have announced a Middlesbrough service, which I wrote about in LNER’s Middlesbrough And London Service. Starts On December 13th.

  • There will be one tpd in both directions
  • Intermediate stops will be at Thornaby and York.
  • The Middlesbrough and London service will leave Middlesbrough from Platform 1 at 07:08 and arrive in King’s Cross at 10:22.
  • The London and Middlesbrough service will leave King’s Cross at 15:25 and arrive in Middlesbrough in Platform 2 at 18:18.

There appear to be some curiosities in the timetabling of these trains, which I may explore later.

I would assume that is because LNER want a competitive time of three hours between King’s Cross and Middlesbrough.

These are Southbound times between Eaglescliffe and King’s Cross in the morning.

  • Grand Central –  Two hours and thirty-nine minutes
  • LNER – Three hours and two minutes

Is this because the Class 180 train is a genuine 125 mph train on diesel and the Class 800 train is not?

If my crude estimate of time savings because of digital signalling South of Doncaster can be applied, this would imply a reduction in journey time of at least eleven minutes, which would put a time between London King’s Cross and Middlesbrough of around three hours.

Conclusion

Of the cities and towns in the North, that I have discussed only Bradford, Harrogate, Huddersfield, Hull and Middlesbrough, are ones that will be difficult to be provided with a two-hour journey time to and from London. But all should be possible in close to or under two hours and thirty minutes.

The Seat Of Aurora

The title of this post, is the same as that of an article in the August 2021 Edition of Modern Railway.

The article has this sub-title.

East Midlands Railway has finalised the new seats for its new trains, and they’re completely useless – as ironing boards.

Note.

  1. East Midlands Railway‘s new trains are Class 810 trains, which are Hitachi AT300 express trains, as used by several operators.
  2. Some passengers and industry commentators have criticised the seats in these trains as like ironing boards.
  3. Abellio Greater Anglia, who are a sister company to East Midlands Railway, also choose the seats for their new trains with care. I wrote No ‘Ironing Board seats’ For Greater Anglia’s New Trains, about their seat choice.

Ian Walmsley, who wrote the article for Modern Railways says this about the Seat of Aurora.

My verdict is that it is a good seat, and that is in absolute terms – not just saying it is better than an 800, which it would have to be really.

For myself, the proof of the seating will be in the sitting.

Thoughts On The Eastern Leg Of High Speed Two

These are a few thoughts on the Eastern Leg of High Speed Two.

Serving The North-East Quarter Of England From London

In Anxiety Over HS2 Eastern Leg Future, I gave a table of timings from London to towns and cities in the North-East quarter of England from Lincoln and Nottingham Northwards.

I’ll repeat it here.

  • Bradford – Will not be served by High Speed Two – One hour and fifty-four minutes
  • Cleethorpes – Will not be served by High Speed Two – Two hours and fifty-one minutes
  • Darlington – One hour and forty-nine minutes – One hour and forty-nine minutes
  • Doncaster – Will not be served by High Speed Two – One hour
  • Edinburgh – Three hours and forty minutes via Western Leg – Three hours and thirty minutes.
  • Grimsby – Will not be served by High Speed Two – Two hours and thirty-six minutes
  • Harrogate – Will not be served by High Speed Two – One hour and fifty-two minutes
  • Huddersfield – Will not served by High Speed Two – Two hours and eight minutes
  • Hull – Will not be served by High Speed Two – One hour and fifty minutes
  • Leeds – One hour and twenty-one minutes – One hour and thirty minutes
  • Lincoln – Will not be served by High Speed Two – One hour and fifty-one minutes
  • Middlesbrough – Will not be served by High Speed Two – Two hours and twenty minutes
  • Newcastle – Two hours and seventeen minutes – Two hours and sixteen minutes
  • Nottingham – One hour and seven minutes – One hour and fifty minutes
  • Scarborough – Will not be served by High Speed Two – Two hours and fifty-seven minutes
  • Sheffield – One hour and twenty-seven minutes – One hour and twenty-seven minutes
  • Skipton – Will not be served by High Speed Two – Two hours and seven minutes
  • Sunderland – Will not be served by High Speed Two – Two hours and thirty minutes
  • York – One hour and twenty-four minutes – One hour and twenty-four minutes

Note.

  1. I have included all destinations served by Grand Central, Hull Trains and LNER.
  2. I have included Nottingham and Sheffield for completeness and in case whilst electrification is installed on the Midland Main Line, LNER run services to the two cities.
  3. I suspect LNER services to Bradford, Harrogate, Huddersfield and Skipton will split and join at Leeds.

There are a total of nineteen destination in this table.

  • Twelve are not served by High Speed Two.
  • Six are not more than fifteen minutes slower by the East Coast Main Line.

Only Nottingham is substantially quicker by High Speed Two.

Serving The North-East Quarter Of England From Birmingham

Fenland Scouser felt the above table might be interesting to and from Birmingham with or without the Eastern Leg of High Speed Two.

I think, I can give more information than that and it should be possible to give for each destination the following.

  • Whether of not the route exists on High Speed Two.
  • Time on High Speed Two from Birmingham.
  • Time on High Speed Two and Northern Powerhouse Rail from Birmingham via Manchester
  • Time by current trains from Birmingham

In the following table, the fields are in the order of the previous table.

  • Bradford – No direct route – No time – One hour and three minutes – Two hours and twenty-seven minutes
  • Cleethorpes – No direct route – No time – Three hours and eight minutes – Three hours and eighteen minutes
  • Darlington – Route Exists – One hour and twenty-three minutes – One hour and forty minutes – Two hours and fifty-five minutes
  • Doncaster – No direct route – No time – One hour and thirty-six minutes – Two hours and nineteen minutes
  • Edinburgh- Route Exists – Three hours and fourteen minutes – Four hours – Four hours and thirteen minutes
  • Grimsby – No direct route – No time – Two hours and fifty-three minutes – Three hours and three minutes
  • Harrogate – No direct route – No time – One hour and twenty-eight minutes – Three hours
  • Huddersfield – No direct route – No time – Fifty-six minutes – Two hours and eleven minutes
  • Hull – No direct route – No time – One hour and forty-four minutes – Three hours and two minutes
  • Leeds – Route Exists – Forty-nine minutes – One hour and six minutes – One hour and fifty-nine minutes
  • Lincoln – No direct route – No time – Two hours and fifty-three minutes – Two hours and thirteen minutes
  • Middlesbrough – No direct route – No time – Two hours and twenty-nine minutes – Three hours and thirty-two minutes
  • Newcastle – No direct route – No time – Two hours and four minutes – Three hours and twenty-six minutes
  • Nottingham – Route Exists – Fifty-seven minutes – Two hours and fifty-five minutes – One hour and ten minutes
  • Sheffield – Route Exists – Thirty-five minutes – One hour and thirty-four minutes – One hour and fifteen minutes
  • Skipton – No direct route – No time – One hour and forty-three minutes – Two hours and fifty-two minutes
  • Sunderland – No direct route – No time – Two hours and fifty-nine minutes – Three hours and fifty-eight minutes
  • York – Route Exists – Fifty-seven minutes – One hour and twenty-eight minutes – Two hours and twenty-seven minutes

Note.

  1. No time means just that!
  2. One of the crucial times is that Birmingham Curzon Street and Leeds is just an hour and six minutes via High Speed Two and Northern Powerhouse Rail. This time gives good times to all destinations served from Leeds.
  3. Nottingham and Sheffield are both around an hour and fifteen minutes from Birmingham New Street, by the current trains.

I’ll now look at some routes in detail.

Birmingham And Leeds

The time of one hour and six minutes is derived from the following.

  • Birmingham Curzon Street and Manchester Piccadilly by High Speed Two – Forty-one minutes
  • Manchester Piccadilly and Leeds by Northern Powerhouse Rail – Twenty-five minutes

It would be seventeen minutes slower than the direct time of forty-nine minutes.

But it is quicker than the current time of one hour and fifty-nine minutes

Note.

  1. As Manchester Piccadilly will have a time to and from London of one hour and eleven minutes, Leeds will have a time of one hour and twenty-six minutes to London via Northern Powerhouse Rail and Manchester.
  2. If the Eastern Leg is built, The London and Leeds time will be one hour and twenty-one minutes.
  3. The Eastern Leg would therefore save just five minutes.

The Northern Powerhouse route could probably mean that Huddersfield, Bradford and Hull would be served by High Speed Two from London.

Manchester Airport, Manchester Piccadilly and Leeds would be connected by a tunnel deep under the Pennines.

  • Manchester Piccadilly, Huddersfield and Bradford could be underground platforms added to existing stations.
  • Piccadilly and Leeds would have a journey time of under 25 minutes and six trains per hour (tph).
  • The tunnel would also carry freight.
  • It would be modelled on the Gotthard Base Tunnel in Switzerland.

I wrote full details in Will HS2 And Northern Powerhouse Rail Go For The Big Bore?

Birmingham And Nottingham

The time of two hours and fifty-five minutes is derived from the following.

  • Birmingham Curzon Street and Manchester Piccadilly by High Speed Two – Forty-one minutes
  • Manchester Piccadilly and Leeds by Northern Powerhouse Rail – Twenty-five minutes
  • Leeds and Nottingham – One hour and forty-nine minutes

It would be one hour and fifty-eight minutes slower than the direct time of fifty-nine minutes.

The current time of one hour and ten minutes is much quicker.

Birmingham And Sheffield

The time of two hours and thirty-four minutes is derived from the following.

  • Birmingham Curzon Street and Manchester Piccadilly by High Speed Two – Forty-one minutes
  • Manchester Piccadilly and Leeds by Northern Powerhouse Rail – Twenty-five minutes
  • Leeds and Sheffield – One hour and twenty-eight minutes

It would be one hour and fifty-nine minutes slower than the direct time of thirty-five minutes.

The current time of one hour and fifteen minutes is much quicker.

Conclusions On The Timings

I am led to the following conclusions on the timings.

The building of the Eastern Leg of High Speed Two gives the fastest times between Birmingham and Leeds, Nottingham and Sheffield.

But if the Eastern Leg of High Speed Two is not built, then the following is true, if Northern Powerhouse Rail is created between Manchester and Leeds.

The time of an hour and six minutes between Birmingham Curzon Street and Leeds is probably an acceptable time.

This time probably enables  acceptable times between Birmingham Curzon Street and destinations North of Leeds.

But with Nottingham and Sheffield the current CrossCountry service is faster than the route via Manchester.

The speed of the CrossCountry services surprised me, but then there is a section of 125 mph running between Derby and Birmingham, which is used by CrossCountry services between Birmingham New Street and Leeds, Nottingham and Sheffield.

This table gives details of these services.

  • Birmingham New Street and Leeds – 116,4 miles – One hour and 58 minutes – 59.3 mph
  • Birmingham New Street and Nottingham – 57.2 miles – One hour and 14 minutes – 46.4 mph
  • Birmingham New Street and Sheffield – 77.6 miles – One hour and 18 minutes – 59.7 mph

Note.

  1. The Leeds and Sheffield services are run by 125 mph Class 220 trains.
  2. The Notting service is run by 100 mph Class 170 trains.
  3. All trains are diesel-powered.

As there is 125 mph running between Derby and Birmingham, the train performance probably accounts for the slower average speed of the Nottingham service.

CrossCountry And Decarbonisation

Consider.

  • CrossCountry has an all-diesel fleet.
  • All train companies in the UK are planning on decarbonising.
  • Some of CrossCountry’s routes are partially electrified and have sections where 125 mph running is possible.

The only standard train that is built in the UK that would fit CrossCountry’s requirements, would appear to be one of Hitachi’s 125 mph trains like a bi-mode Class 802 train.

  • These trains are available in various lengths
  • Hitachi will be testing battery packs in the trains in the next year, with the aim of entering service in 2023.
  • Hitachi have formed a company with ABB, which is called Hitachi ABB Power Grids to develop and install discontinuous electrification.

When CrossCountry do replace their fleet and run 125 mph trains on these services several stations will be connected to Birmingham for High Speed Two.

The route between Leeds and Birmingham via Sheffield is part of the Cross Country Route, for which electrification appears to have planned in the 1960s according to a section in Wikipedia called Abortive British Rail Proposals For Complete Electrification,

I suspect that the following times could be achieved with a frequency of two tph

  • Birmingham New Street and Leeds – 90 minutes
  • Birmingham New Street and Nottingham – 60 minutes
  • Birmingham New Street and Sheffield – 60 minutes

It is not the Eastern Leg of High Speed Two, but it could do in the interim.

Electrification Of The Midland Main Line

I don’t believe that the Midland Main Line needs full electrification to speed up services to Derby, Nottingham and Sheffield, but I believe that by fitting batteries to Hitachi’s Class 810 trains, that will soon be running on the line and using the Hitachi ABB Power Grids system of discontinuous electrification, that the route can be decarbonised.

I would also apply full digital in-cab signalling to the Midland Main Line.

Conclusion

We will need the Eastern Leg of High Speed Two at some time in the future, but if we do the following we can do more than cope.

  • Create Northern Powerhouse Rail between Manchester and Leeds, so that High Speed Two can serve Leeds and Hull via Manchester.
  • Decarbonise CrossCountry with some 125 mph battery-electric trains.
  • Electrify the Midland Main Line.

I would also deliver as much as possible before Phase 1 and 2a of High Speed Two opens.

Thoughts On Batteries On A Hitachi Intercity Tri-Mode Battery Train

This Hitachi infographic describes a Hitachi Intercity Tri-Mode Battery Train.

Hitachi are creating the first of these battery trains, by replacing one of the diesel power-packs in a Class 802 train with a battery-pack from Hyperdrive Innovation of Sunderland.

This press release from Hitachi is entitled Hitachi And Eversholt Rail To Develop GWR Intercity Battery Hybrid Train – Offering Fuel Savings Of More Than 20%, gives a few more details.

The Class 802 train has the following characteristics.

  • Five cars.
  • Three diesel power-packs, each with a power output of 700 kW.
  • 125 mph top speed on electricity.
  • I believe all intermediate cars are wired for diesel power-packs, so can all intermediate cars have a battery?

In How Much Power Is Needed To Run A Train At 125 Or 100 mph?, I estimated that the trains need the following amounts of energy to keep them at a constant speed.

  • Class 801 train – 125 mph 3.42 kWh per vehicle mile
  • Class 801 train – 100 mph 2.19 kWh per vehicle mile

The figures are my best estimates.

The Wikipedia entry for the Class 800 train, also gives the weight of the diesel power-pack and all its related gubbins.

The axle load of the train is given as 15 tonnes, but for a car without a diesel engine it is given as 13 tonnes.

As there are four axles to a car, I can deduce that the diesel power-pack and the gubbins, weigh around eight tonnes.

How much power would a one tonne battery hold?

This page on the Clean Energy institute at the University of Washington is entitled Lithium-Ion Battery.

This is a sentence from the page.

Compared to the other high-quality rechargeable battery technologies (nickel-cadmium or nickel-metal-hydride), Li-ion batteries have a number of advantages. They have one of the highest energy densities of any battery technology today (100-265 Wh/kg or 250-670 Wh/L).

Using these figures, a one-tonne battery would be between 100 and 265 kWh in capacity, depending on the energy density.

As it is likely that if the diesel power-pack replacement would probably leave things like fuel tanks and radiators behind, so that the diesel engines could be reinstalled, I would expect that a battery of around four tonnes would be fitted.

On the basis of the University of Washington’s figures a 400 kWh battery pack would certainly be feasible.

Using. the energy use at 100 mph of 2.19 kWh per vehicle mile, I can get the following ranges for different battery sizes.

  • 400 kWh battery – 36.53 miles
  • 500 kWh battery – 45.67 miles
  • 600 kWh battery – 54.80 miles
  • 800 kWh battery – 73.06 miles

As Lincoln and Newark are just 16.6 miles apart, it looks to me that a 500 or 600 kWh battery could be a good choice for that route, as it would leave enough hotel power for the turnround.

It should also handle shorter routes like these.

  • Newbury and Bedwyn – 13.3 miles.
  • Didcot and Oxford – 10.3 miles
  • Newark and Lincoln – 16.6 miles
  • Leeds and Harrogate – 18.3 miles
  • Northallerton and Middlesbrough – 20 miles
  • Hull and Temple Hirst Junction and Hull – 36.1 miles

Some routes like Temple Hirst Junction and Hull would need charging at the destination.

The Range Of A Five Car Train With Three Batteries

Suppose a Hitachi Intercity Tri-Mode Battery Train had three battery-packs and no diesel engines.

  • It would be based on Hitachi Intercity Tri-Mode Battery Train technology.
  • It would have two driver cars without batteries.
  • It would have three intermediate cars with 600 kWh batteries.
  • It would have 1800 kWh in the batteries.
  • The train would be optimised for 100 mph running.
  • My estimate says it would need 2.19 kWh per vehicle mile to cruise at 100 mph.

It could have a range of up to 164 miles.

If the batteries were only 500 kWh, the range would be 137 miles.

The Ultimate Battery Train

I think it would be possible to put together a nine car battery-electric train with a long range.

  • It would be based based on Hitachi Intercity Tri-Mode Battery Train technology, which would be applied to a Class 800 or Class 802 train.
  • It would have two driver cars without batteries.
  • It would have seven intermediate cars with 600 kWh batteries.
  • It would have a total battery capacity of 4200 kWh.
  • The train would be optimised for 100 mph running.
  • My estimate in How Much Power Is Needed To Run A Train At 125 Or 100 mph?, said it would need 2.19 kWh per vehicle mile to cruise at 100 mph.

That would give a range of over 200 miles.

If the batteries were only 500 kWh, the range would be 178 miles.

Aberdeen, Inverness, Penzance and Swansea here we come.

Can Hitachi Increase The Range Further?

There are various ways that the range can be improved.

  • More electrically-efficient on-board systems like air-conditioning.
  • A more aerodynamic nose.
  • Regenerative braking to the batteries.
  • Batteries with a higher energy density.
  • Better driver assistance software.

Note.

  1. Hitachi have already announced that the Class 810 trains for East Midlands Railway will have a new nose profile.
  2. Batteries are improving all the time.

I wouldn’t be surprised to see a ten percent improvement in range by 2030.

Conclusion

I was surprised at some of the results of my estimates.

But I do feel that Hitachi trains with 500-600 kWh batteries could bring a revolution to train travel in the UK.

Edinburgh And Aberdeen

Consider.

  • The gap in the electrification is 130 miles between Edinburgh Haymarket and Aberdeen.
  • There could be an intermediate charging station at Dundee.
  • Charging would be needed at Aberdeen.

I think Hitachi could design a train for this route.

Edinburgh And Inverness

Consider.

  • The gap in the electrification is 146 miles between Stirling and Inverness.
  • This could be shortened by 33 miles, if there were electrification between Stirling and Perth.
  • Charging would be needed at Inverness.

I think Hitachi could design a train for this route.

Plans For £100m Coventry To Nottingham Rail Link Announced

The title of this post, is the same as that of this article on the BBC.

This is the first two paragraphs.

A £100m scheme to reconnect three Midlands cities by rail could be running by 2025, subject to funding, according to a regional transport group.

Midlands Connect said it had completed a strategic business case for a direct link between Coventry, Leicester and Nottingham.

The article also says this about the route.

The group said there was a “strong case” for the project and it had narrowed it down to two – one which called at the Warwickshire town of Nuneaton and one which ran direct between the three cities.

In A Potential Leicester To Coventry Rail Link, which I wrote in February 2019, I talked about this link and came to the conclusion it was feasible.

But things have moved on in those two years and these are my updated thoughts.

Via Nuneaton Or Direct

This Google Map shows the rail layout to the South of Nuneaton station.

Note.

  1. The multi-track electrified railway running North-West and South-East is the Trent Valley section of the West Coast Main Line.
  2. Branching off to the South-West is the Coventry and Nuneaton Line.
  3. Branching off to the South-East is the line to Leicester.

Nuneaton station is off the map to the North on the West Coast Main Line.

Unfortunately, services to Coventry and Leamington Spa call in Platform 1 on the Western side of the station and services between Leicester and Birmingham call in platforms 6 and 7 on the Eastern side.

This probably rules out a clever solution, where perhaps an island platform, has Birmingham and Leicester services on one side and Coventry and Leicester services on the other.

This Google Map shows Nuneaton station.

Note.

  1. Platform 6 and 7 form the island platform on the North-East side of the station.
  2. Birmingham trains call in Platform 6.
  3. Leicester trains call in Platform 7.

The track layout for Platforms 6 and 7 appears comprehensive with crossovers allowing both platforms to be used for services to both cities.

This Google Map shows the crowded track layout to the South of the station.

The only possibility would appear to be a single track dive-under that connected Platform 6 and/or 7 to the Coventry and Nuneaton Line on the other side of the West Coast Main Line.

I feel that costs would rule it out.

I suspect that a direct solution cutting out Nuneaton might be possible.

This Google Map shows the three routes diverging to the South of Nuneaton station.

It might be possible to connect the Coventry and Leicester Lines, but the curve might be too tight.

The alternative could be to build a dive-under that would connect Platform 1 to the Leicester Line.

  • It would appear that it could be the easiest and most affordable option.
  • Trains would reverse in Nuneaton station.

It is certainly a tricky problem, but I do believe there is a simple cost-effective solution in there somewhere.

Nuneaton Parkway Station

This page on Coventry Live gives some information about the proposed Nuneaton Parkway station.

There is also a proposed station, to be called Nuneaton Parkway, situated off the A5 between Hinckley and Nuneaton.

This Google Map shows the area where the A5 crosses the Birmingham-Peterborough Line, that runs between Hinckley and Nuneaton..

This must surely be one of the best sites to build a new Parkway station in the UK.

  • The triangular site is a waste transfer station operated by Veolia Environmental Services UK.
  • It has a direct connection to the A5, which could be easily improved, with perhaps a roundabout.
  • Doing a crude estimate from the Google Map, I calculate that the site is about sixteen hectares, which is surely a good size for a Parkway station.
  • There’s even quite a lot of new housing within walking and cycling distance.

It would also appear that the station could be built on this site without major disruption to either road or rail traffic.

The Stations And Timing

This document on the Midlands Connect web site, gives their aims for the service.

  • Coventry and Leicester – 38 minutes from 54 minutes with one change.
  • Coventry and Loughborough – 50 minutes from 88 minutes with otwo changes.
  • Coventry and East Midlands Parkway – 56 minutes from 104 minutes with otwo changes.
  • Coventry and Nottingham – 70 minutes from 108 minutes with otwo changes.

The service would have a frequency of two trains per hour (tph).

If the train did the same station stops as the current services between Coventry and Leicester, it could stop at all or a selection of the following intermediate stations.

  • South Wigston
  • Narborough
  • Hinckley
  • Nuneaton
  • Bermuda Park
  • Bedworth
  • Coventry Arena

The total time would appear to be around fifty minutes, with 28 minutes for Leicester to Nuneaton and 22 minutes from Nuneaton to Coventry. Although the BBC article says that Coventry and Leicester would drop from the current 54 minutes to 38 minutes.

Currently services between Leicester and Birmingham New Street stations are run by CrossCountry.

  • One tph – Birmingham New Street and Cambridge or Stansted Airport
  • One tph – Birmingham New Street and Leicester

Note that not all intermediate stations receive a two tph service.

Would a two tph service between Leicester and Coventry enable all the stations on the route to have a two tph service?

The Current Leicester And Nottingham Service

Currently the following services run between Leicester and Nottingham.

  • 1 tph – EMR InterCity – Direct
  • 1 tph – EMR InterCity – Via Loughborough, East Midlands Parkway and Beeston
  • 1 tph – EMR Regional – Via Syston, Sileby, Barrow-upon-Soar, Loughborough, East Midlands Parkway, Attenborough and Beeston

Note.

  1. Timings vary between 23 and 49 minutes.
  2. Four tph between Leicester and Nottingham would be a Turn-Up-and-Go service that would attract passengers.
  3. The BBC article is indicating a Coventry and Nottingham time of 70 minutes, which would indicate a Leicester and Nottingham time of 32 minutes, which would appear to be in-line with the EMR Intercity service that stops at Loughborough, East Midlands Parkway and Beeston.

It looks to me that a fourth semi-fast service between Leicester and Nottingham would not be a bad idea.

But Midlands Connect are proposing two extra tph between Coventry and Nottingham.

A Coventry And Nottingham Service

Consider.

  • An two tph service would fit in well and give a Turn-Up-and-Go service between Leicester and Nottingham.
  • The Coventry and Nottingham time of 70 minutes indicates that the train would need to be to EMR InterCity standard.
  • If there is an allowance of twenty minutes at either end of the route, this would indicate a round trip of three hours.

This standard of service would need an operational fleet of six five-car Class 810 trains or similar for a frequency of two tph.

I very much feel that there should be electrification of the Midland Main Line between Leicester and either East Midlands Parkway or Derby.

This would mean that the Coventry and Nottingham route would break down as follows.

  • Coventry and Nuneaton – 19,2 miles – No electrification
  • Nuneaton and Leicester – 18.8 miles – No electrification
  • Leicester and East Midlands Parkway – 19.1 miles – Possible electrification
  • East Midlands Parkway and Nottingham – 8.4 miles – No electrification

Note that electrification is already available  at Coventry and Nuneaton.

The Coventry and Nottingham route would appear to be possible with battery-electric trains, after the route between Leicester and East Midlands Parkway is electrified.

An Improved Birmingham And Cambridge Service

If Nottingham and Coventry needs a fast two tph service stopping at the major towns and cities in between, surely Birmingham and Cambridge need a similar service.

  • It could call at Nuneaton, Leicester, Melton Mowbray, Oakham, Stamford, Peterborough, Ely and Cambridge North.
  • Some services could be extended to Stansted Airport.
  • It would have a frequency of two tph.

The Birmingham and Cambridge route would break down as follows.

  • Birmingham and Nuneaton – 21 miles – No electrification
  • Nuneaton and Leicester – 18.8 miles – No electrification
  • Leicester and Peterborough – 40 miles – No electrification
  • Peterborough and Ely – 30.5 miles – No electrification
  • Ely and Cambridge – 14.7 miles – Electrified.

Note that electrification is already available  at Birmingham, Nuneaton and Peterborough.

The Birmingham and Cambridge route would appear to be possible with battery-electric trains, if Leicester station were to be electrified.

Midland Connect’s Proposed Leeds and Bedford Service

I wrote about this service in Classic-Compatible High Speed Two Trains At East Midlands Hub Station.

It would run between Leeds and Bedford stations.

It would use the Midland Main Line between Bedford and East Midlands Hub stations.

It would use High Speed Two between East Midlands Hub and Leeds stations.

It would stop at Wellingborough, Kettering, Market Harborough, Leicester, Loughborough and East Midlands Hub stations.

  • The service frequency could be hourly, but two trains per hour (tph) would be better.
  • Leicester and Leeds would take 46 minutes.

Obviously, it wouldn’t run until the Eastern Leg of High Speed Two opens, but it could open up the possibility of Coventry and Leeds in under ninety minutes.

Driving takes over two hours via the M1.

Conclusion

This looks to be a very feasible and fast service.

It also illustrates how extending the electrification on the Midland Main Line can enable battery-electric trains to provide connecting services.

Enough electrification at Leicester and a few miles North of the station to fully charge passing trains would probably be all that is needed.

Department Of Transport Claims London and Sheffield Times Could Be Cut By Thirty Minutes

In this article on the BBC, which is entitled Government Announce £401m Boost For Rail Services, this is said.

The funding announcement coincided with the completion of the first phase of the £1.5bn Midland Main Line Upgrade, which has supported the launch of East Midlands Railway’s (EMR) first electric services on the route between Corby in Northamptonshire and London St Pancras.

The project will see journey times between Sheffield and London cut by up to 30 minutes, the DfT said.

So how feasible is the claim of a thirty minute cut in London and Sheffield timings?

On Monday, the 07:30 train from London to Sheffield, covered the 164.7 miles in two hours and twelve minutes at an average speed of 74.9 mph.

If that train had done the trip in one hour and forty-two minutes, that would have been an average speed of 96.9 mph.

By the time, the new Class 810 trains arrive in a couple of years, they will be able to use the new electrification to Market Harborough, when on Monday the 82.8 miles without a stop, was covered in an hour, at an average speed of 82.8 mph.

These new trains are 125 mph electric trains under the wires and they will have two separate fast lines on which to run.

Example time savings at various average speeds to Market Harborough are as follows.

  • 100 mph – 10 minutes saving.
  • 110 mph – 14.8 minutes saving.
  • 125 mph – 20.3 minutes saving
  • 130 mph – 21.8 minutes saving
  • 140 mph – 24.6 minutes saving

Note.

  1. The faster the average, the greater the time saving.
  2. Faster than 125 mph would only be possible with full in-cab digital signalling, which is currently being installed on the East Coast Main Line.
  3. I have been to Leicester in an InterCity 125, which was running at 125 mph most of the way.

But it does look like the new Class 810 trains will be able to save around twenty minutes to Sheffield, by making full use of the electrification between London and Market Harborough.

They would need to save just ten minutes between Market Harborough and Sheffield.

The Monday Train covered the 81.9 miles between Market Harborough and Sheffield in one hour and twelve minutes, which is an average speed of 68.3 mph.

To obtain the saving of ten minutes, it would need to do the journey in one hour and two minutes, which would be an average speed of 79.3 mph.

Given that the new Class 810 trains are designed to cruise at 125 mph on diesel, I don’t think this is an impossible objective.

What Will Be The Ultimate Time Between London and Sheffield On The Midland Main Line?

I believe that the following two sections of the Midland Main Line can be easily electrified.

  • Between Leicester and Derby without the problem of the bridge at the South end of Leicester station, which would be so disruptive.
  • Clay Cross North Junction and Sheffield which will be electrified for High Speed Two. I doubt Derby and Clay Cross Junction will be electrified as it’s a World Heritage Site.

On my Monday train, the following are times North of Leicester.

  • Leicester and Derby is 29.3 miles, which is covered in 32 minutes at an average speed of 55 mph, which includes five stops. Raise this to 110 mph and the journey time is just 16 minutes or a saving of 16 minutes.
  • Derby and Clay Cross North Junction is 21.8 miles, which is covered in 13 minutes at an average speed of 100 mph. By averaging 120 mph, there would be a saving of 2.1 minutes.
  • Cross North Junction and Sheffield is 15.5 miles, which is covered in 16 minutes at an average speed of 58.2 mph.

Note.

  1. Savings would come between Leicester and Derby because of 125 mph linespeed and faster stops because of electrification.
  2. I believe that Hitachi battery-electric trains could sustain 125 mph on battery alone between Derby and Clay Cross North Junction, if they entered the section without electrification at full speed with full batteries. Now that is what I call a battery-electric train!
  3. There must be a minute or two to be saved on an electrified section into Sheffield with the stop at Chesterfield.

Add up all the savings and I feel that an hour and a half is possible between London and Sheffield.

And what time is High Speed Two claiming? One hour and twenty-seven minutes!

Could A Battery-Electric Train Cruise At 125 mph?

This may seem a silly idea, but then trains don’t care where they get their electricity from.

On the 21.8 miles between Derby and Clay Cross North, a sizeable proportion of energy will be used to accelerate the train up to the linespeed for the electrified section.

When the train enters the section without electrification, it will have two sources of energy.

  • The electricity in the full batteries.
  • The kinetic energy in the train at the required speed.

As the train runs through the section air and rolling resistance will tend to slow the train and electricity from the battery will be used to maintain speed.

In How Much Power Is Needed To Run A Train At 125 mph?. I estimated that for a Class 801 train to maintain 125 mph needs 3.42 kWh per vehicle mile.

A simple sum of 21.8 * 5 * 3.42 gives an energy need of 372.8 kWh to run between Derby and Clay Cross North Junction.

I’m sure than Hitachi can fit a 400 kWh battery in a five-car Class 810 train.

Would a slightly larger battery and in-cab signalling allow battery-electric trains to run at 140 mph? If the track allowed it, I don’t see why not!

Conclusion

I believe the Department of Transport’s statement of saving thirty minutes between London and Sheffield is feasible.

But so is a time of an hour-and-a half, which will give High Speed Two a run for its money!

A Trip To Corby

I took these pictures on a trip to Corby this morning.

These are my thoughts.

Trains To And From Corby

I got a Class 222 train to Corby and an eight-car Class 360 train back.

Brent Cross West Station

There was a lot of constructruction activity at the new Brent Cross West station.

Luton Airport Parkway Station

The extensions to Luton Airport Parkway station look to be comprehensive, with several escalators.

The Luton DART connection to Luton Airport appears to be under test, so should open in 2022.

But will there be any air passengers to use it?

I last used it in 2008, when I went to see England play in Belarus.

Electrification North Of Bedford

The electrification North of Bedford station is obviously complete on the slow lines, but on the fast lines, as the pictures show, the gantries are all erected, but there are still wires to be installed.

But as the Class 810 trains won’t be in service until 2023, there’s still a bit of time.

The gantries certainly look sturdy, as this picture shows.

They’re certainly built for 125 mph, but as the Class 810 trains will be capable of 140 mph with full digital in-cab signalling, I would hope that the electrification has been installed to that standard. Or at least to a standard, that can be easily upgraded!

Corby Station

Corby station has been finished to a single-platform station, which is able to accept a twelve-car Class 360 train.

This should be adequate for the current half-hourly service, as a single platform can handle a least four trains per hour (tph) and several around the country regularly do.

Both tracks through the station are electrified and I suspect with a second platform bridge, both could be used by electric trains to create a two-platform station.

But there would appear to be no need at the moment.

Even, if it were to be decided to extend one tph to Oakham and Melton Mowbray stations, this could probably be accommodated on the single-platform.

Network Rail seem to have already installed a crossover South of Corby station, so that trains can use the single platform.

Serving Oakham And Melton Mowbray

I discussed this extension in detail in Abellio’s Plans For London And Melton Mowbray Via Corby And Oakham.

In the related post, I said this.

This page on the Department for Transport web site is an interactive map of the Abellio’s promises for East Midlands Railway.

These are mentioned for services to Oakham and Melton Mowbray.

    • After electrification of the Corby route there will continue to be direct service each way between London and Oakham and Melton Mowbray once each weekday, via Corby.
    • This will be operated with brand new 125mph trains when these are introduced from April 2022.

This seems to be a very acceptable minimum position.

When my Class 222 train arrived in Corby at 1154, it waited a couple of minutes then took off to the North.

I then took the next train to London, which was an eight-car Class 360 train which formed the 1211 service back to St. Pancras.

Meanwhile the Class 222 train, that I’d arrived on did a reverse in the Corby North Run Around Loop finally arriving back in Corby at 1345. The train had taken one hour and forty-nine minutes to return to Corby.

It might be just coincidence, but are East Midlands Railway doing timing tests to see if services can be extended to Oakham And Melton Mowbray?

It should be noted that service times North of Corby are as follows.

  • Corby and Oakham – 19 mins – 14.3 miles
  • Corby and Melton Mowbray – 31 mins – 25.7 miles
  • Melton Mowbray and Leicester – 17 mins – 12.8 miles (estimate) – CrossCountry service

My logic goes like this.

  • It looks to me that it would not be unreasonable that a Class 222 train could run between Corby and Leicester in forty-eight minutes.
  • Double that and you get one hour and thirty eight minutes, for a journey from Corby to Leicester and back.
  • Subtract that time from the one hour and forty-nine minutes that my train took to reverse and there is eleven minutes for a turnback at Leicester station.
  • Eleven minutes would certainly be long enough to tidy a train and for the crew to change ends.

I also believe that the 35.8 miles would be possible for a Class 810 train fitted with one or more battery power-packs instead of a similar number of the four diesel engines.

So are East Midlands Railway doing tests to find the most efficient way to serve Oakham And Melton Mowbray?

On The Corby Branch

I travelled North on a Class 222 diesel train and South on an electric Class 360 train.

On the Corby branch, I was monitoring the train speed on an app on my phone and both trains travelled at around 90 mph for most of the way.

There were sections at up to 100 mph and the track was generally smooth.

I was left with the impression, that trains might be able to go faster on the branch.

Average speeds for the 2.5 miles of the branch were as follows according to these timings from realtimetrains.

  • Class 222 train – Arriving – 5.25 mins – 28.6 mph
  • Class 222 train – Leaving – 5 mins – 30 mph
  • Class 360 train – Arriving – 7.5 mins – 20 mph
  • Class 360 train – Leaving – 5 mins – 30 mph

It doesn’t appear that there are much difference in the timings, although it might be said, that the electric approach is more cautious.

The Class 360 Trains

The Class 360 trains have not been refurbished yet although as my pictures show, some have been given a new livery.

In Are Class 360 Trains Suitable For St. Pancras And Corby?, I said this about the train refurbishment.

This page on the Department for Transport web site is an interactive map of the Abellio’s promises for East Midlands Railway.

These features are mentioned for Midland Main Line services to Corby.

    • Increased capacity
    • Twelve-car trains in the Peak.
    • More reliable service
    • Improved comfort
    • Passenger information system
    • Free on-board Wi-Fi
    • At-seat power sockets
    • USB points
    • Air conditioning
    • Tables at all seats
    • Increased luggage space
    • On-board cycle storage

What more could passengers want?

It certainly hasn’t happened in full.

I did ask a steward, when the new interiors will be installed and he said they were running late because of the pandemic.

Performance Of The Class 360 Trains

I used my app to follow the speed of the Class 360 train, that brought me back to London.

  • The train hit a maximum speed of about 105 mph.
  • The train arrived in London a minute late.

I feel that as the drivers get used to their new charges, they will match the timetable.

Conclusion

I have a feeling that in a couple of years, these trains will fulfil Abellio’s promises.

Could Trains From The North Connect To High Speed One At St. Pancras?

I was casually flying my virtual helicopter over the throat of St. Pancras International station, when I took a few pictures.

This Google Map shows the Northern ends of the platforms and the tracks leading in.

Note.

  1. Platforms 1-4 to the West with darker tracks handle the East Midlands Railway services.
  2. Platforms 5-10 in the centre with lighter tracks formed of three shorter islands handle the Eurostar services.
  3. Platforms 11-13 to the East with longer platforms handle the Southeastern HighSpeed services.

This Google Map shows the East Midlands Railway platforms.

Note.

  1. There are two island platforms; 1-2 and 3-4.
  2. The four platforms are served by two tracks, that connect to the fast lines of the Midland Main Line.
  3. The platforms will be able to handle a pair of Class 810 trains, which will be 240 metres long.
  4. Will the two trains per hour (tph) using Class 360 trains between London and Corby always use the same platform at St. Prancras station?

This Google Map shows the Eurostar platforms.

Note.

There are three island platforms; 5-6, 7-8 and 9-10.

The two island platforms in the West are for East Midlands Railway services.

The two longer island platforms in the East are for Southeastern HighSpeed services.

The six platforms connect to two fast lines, that are shared with the Southeastern services.

This Google Map shows the lines proceeding to the North.

Note.

  1. There are four sets of tracks.
  2. The two light-coloured tracks on the left are for Thameslink or sidings.
  3. The next two dark-coloured tracks are the two tracks of the Midland Main Line.
  4. The next set of tracks are those connecting to the six Eurostar platforms.
  5. The two tracks on the right are those connecting to the Southeastern Highspeed platforms.
  6. There are crossovers between the Eurostar and Southeastern Highspeed tracks to allow efficient operation of the trains going to and from the twin tracks of High Speed One.

This Google Map shows where the Midland Main Line and High Speed One divide.

Note.

The two dark-coloured tracks of the Midland Main Line running North.

There appear to be four  tracks running North East towards High Speed One.

Between the two sets of tracks two further tracks lead to the North.

The track closest to the Midland Main Line joins to the slow lines of the Midland Main Line.

The other one connects to the North London Line.

This Google Map shows the connecting lines to the High Speed One tunnel.

Note the tunnel portal is in the North-East corner of the map.

  1. It looks to me that the following connections are possible.
  2. St. Pancras station Eurostar platforms and Midland Main Line.
  3. St. Pancras station Eurostar platforms and North London Line to the West.
  4. High Speed One and North London Line to the West.

These connections are in addition to those connections needed to run scheduled services.

They would enable trains to take the following routes.

  • St. Pancras station Eurostar platforms and Midland Main Line.
  • St. Pancras station Eurostar platforms and the West Coast Main Line via North London Line
  • High Speed One and the West Coast Main Line via North London Line
  • St. Pancras station Eurostar platforms and the Great Western Main Line via North London Line
  • High Speed One and the Great Western Main Line via North London Line

I suspect most of the times, that these routes are used it is for engineering purposes or behaps dragging a failed train out of St. Pancras.

But the track layout would seem to allow the following.

Direct electric freight and passenger services between High Speed One and Birmingham, Cardiff, Glasgow, Liverpool and Manchester.

Direct electric passenger services between High Speed One and Sheffield and Leeds, with a reverse at St. Pancras, after the Midland Main Line were to be fully electrified.

Was this by design for Eurostar or was it just what Network Rail ended up with?

A Modern Regional Eurostar Service

These are my thoughts on a modern Regional Eurostar service.

Rolling Stock

High Speed Two is coming and this year, the company will order some of the rolling stock.

There will be fifty-four trains

The trains will be Classic-Compatible for running on the West Coast Main Line.

They will be 200 metres long and be able to run in pairs.

They will be able to operate at 225 mph.

The operating speed of High Speed One is 186 mph.

I can see no reason why trains of this type, couldn’t run between St. Pancras and many destinations in Europe.

North Of England And The Continent

Could this be the service pattern?

  • One train could start in the North West and another in the North East.
  • Both trains would proceed to St. Pancras picking up passengers en route.
  • At St. Pancras the two trains would join together.
  • The driver could then position themselves in the front cab and take High Speed One, through the Channel Tunnel.

The train could even split at Calais to serve two different Continental destinations.

Going North, the spitting and joining would be reversed.

What Infrastructure Would Be Needed?

I suspect the following will be needed.

  • The West Coast Main Line and the Midland Main Line would need in-cab digital ERTMS signalling.
  • Full electrification of the Midland Main Line would probably be necessary, as I don’t think the tunnel allows diesel trains to pass through.
  • Some platform lengthening might be needed.

It would not be an expensive scheme.

What Timings Would Be Possible?

Using current timings you get the following times.

  • Leeds and Paris – Five hours
  • Leeds and Brussels – Four hours forty minutes
  • Manchester and Paris – Five hours
  • Manchester and Brussels – For hours forty minutes
  • Newcastle and Paris – Six hours
  • Newcastle and Brussels – Five hours thirty minutes

Note, that the times are best estimates and include a long stop of several minutes at St. Pancras.

Could Sleeper Service Be Run?

I don’t see why not!

Conclusion

It looks like it may be possible to run regional services to Europe, where pairs of train split and join at St. Pancras.

Thoughts On Faster Trains On Thameslink

The Class 700 trains used by Thameslink only have an operating speed of 100 mph.

I do wonder, if that is a fast enough operating speed for all Thameslink routes.

Sharing The Midland Main Line With 125 mph Trains

A couple of years ago, I travelled back into St. Pancras with a group of East Midlands drivers in a Class 222 train.

They told me several things about the route including that the bridge at the South of Leicester station would be difficult to electrify, as it was low and the track couldn’t be lowered as one of Leicester’s main sewers was under the tracks at the bridge. Perhaps, this is one place, where discontinuous electrification could be used on the Midland Main Line.

They also told me, that sometimes the Thameslink trains were a nuisance, as because of their 100 mph operating speed, the 125 mph Class 222 trains had to slow to 100 mph.

Upgrading Of The Midland Main Line South Of Bedford

The electrification of the Midland Main Line South of Bedford is being updated, so that it is suitable for 125 mph running.

An Analysis Of Services On The Midland Main Line South Of Bedford

The current Class 222 trains are capable of 125 mph and will be replaced by Class 810 trains capable of the same speed on both diesel and electricity.

Currently, a Class 222 train is capable of doing the following on a typical non-stop run between St. Pancras and Leicester.

  • Covering the 30 miles between St. Albans and Bedford in 17 minutes at an average speed of 106 mph.
  • Covering the 50.3 miles between Bedford and Leicester in 30 minutes at an average speed of 100.6 mph.
  • Maintaining 125 mph for long stretches of the route, once the trains is North of London commuter traffic at St. Albans

I can estimate the timings on the 79.2 miles between Leicester and St. Albans, by assuming the train runs at a constant speed.

  • 100 mph – 47.5 minutes
  • 110 mph – 43.2 minutes
  • 125 mph – 38 minutes
  • 140 mph – 34 minutes

Note.

  1. I have done the calculation for 140 mph, as that is the maximum operating speed of the Class 810 train with full in-cab digital signalling.
  2. Trains have been running at 125 mph for a couple of decades on the Midland Main Line.
  3. To get a St. Pancras and Leicester time add another 14 minutes, which is the current time between St. Pancras and St. Albans of a Class 222 train.
  4. Some Off Peak trains are timed at 62-63 minutes between St. Pancras and Leicester.
  5. A time of under an hour between St. Pancras and Leicester might be possible and the Marketing Department would like it.
  6. As Thameslink trains between Bedford and St. Albans stop regularly, they are on the slow lines of the four-track railway, to the North of St. Albans.
  7. South of St. Albans, Thameslink trains often run on the fast lines.

I can expect that East Midlands Railway will want to be running their new Class 810 trains as far as far South as they can at 125 mph, to speed up their services. When the signalling allows it, they’ll want to run at 140 mph.

So they won’t want to see Thameslink’s slow trains on the fast lines.

  • But if you look at the Thameslink trains that do run on the fast lines between St. Albans and St. Pancras, they appear to be the four trains per hour (tph) that run to and from Bedford.
  • Of these trains, two tph terminate at Brighton and two tph terminate at Gatwick Airport.
  • The average speed of a Class 222 train between St. Albans and St. Pancras assuming 14 minutes for the 19.7 miles is 84.4 mph.

So it looks to me that a 100 mph Thameslink train could be able to get away without slowing the East Midland Railway expresses.

But then that is not surprising, as for many years, the Class 222 trains worked happily with 100 mph Class 319 trains.

Is There Scope For Extra And Faster Services Into St. Pancras?

I have only done a simple calculation, but I do wonder if there is scope for the following.

  • Increasing the frequency of trains for both Thameslink and East Midlands Railway.
  • Saving a few minutes on East Midlands Railway services.

Consider.

  • The new Class 810 electric trains will probably have better acceleration and deceleration than the current Class 222 diesel trains, when working using electric power.
  • East Midlands Railway is introducing Class 360 trains that were built as 100 mph trains by Siemens, who are now upgrading them to 110 mph trains.
  • Can Siemens do the same for the Class 700 trains and create a sub-fleet capable of 110 mph running?
  • All trains will be running under full in-cab digital signalling with a large degree of automatic train control.

I feel that if the Class 700 trains had the extra speed, they would make the planning of services South of St. Albans easier and allow the Class 810 trains to both run faster and provide more services.

Sharing The East Coast Main Line With 125 mph Trains

The following Thameslink services run up the East Coast Main Line past Stevenage.

  • Cambridge And Brighton – Two tph – Stops at Royston, Ashwell and Morden (1 tph), Baldock, Letchworth Garden City, Hitchin, Stevenage, Finsbury Park, London St Pancras International, Farringdon, City Thameslink, London Blackfriars, London Bridge, East Croydon, Gatwick Airport, Three Bridges, Balcombe, Haywards Heath and Burgess Hill
  • Cambridge and Kings Cross – Two tph – Stops at Foxton, Shepreth, Meldreth, Royston, Ashwell and Morden, Baldock, Letchworth Garden City, Hitchin, Stevenage, Knebworth, Welwyn North, Welwyn Garden City, Hatfield, Potters Bar and Finsbury Park
  • Peterborough and Horsham – Two tph – Stops at Huntingdon, St Neots, Sandy, Biggleswade, Arlesey, Hitchin, Stevenage, Finsbury Park, London St Pancras International, Farringdon, City Thameslink, London Blackfriars, London Bridge, East Croydon, Coulsdon South, Merstham, Redhill, Horley, Gatwick Airport, Three Bridges, Crawley, Ifield, Faygate (limited) and Littlehaven

Note.

  1. Services are generally run by Class 700 trains, although lately the Kings Cross service seems to use Class 387 trains, which have a maximum speed of 110 mph and a more comfortable interior with tables.
  2. It is intended that the Cambridge and Kings Cross service will be extended to Maidstone East by 2021.

In addition there are two Cambridge Express and Fen Line services.

  • Kings Cross and Ely – One tph – Stops at Cambridge and Cambridge North.
  • Kings Cross and King’s Lynn – One tph – Stops at Cambridge, Cambridge North, Waterbeach, Ely, Littleport, Downham Market and Watlington

Note.

  1. These services are generally run by Class 387 trains.
  2. Cambridge and King’s Cross is timetabled at around fifty minutes.

Adding all of this together means that slower services on the East Coast Main Line are comprised of the following in both directions.

  • Three tph – 110 mph – Class 387 trains
  • Four tph – 100 mph – Class 700 trains

These seven trains will have to be fitted in with the 125 mph trains running services on the East Coast Main Line, for LNER, Grand Central, Hull Trains and East Coast Trains.

There are also the following problems.

  • All trains must navigate the double-track section of the East Coast Main Line over the Digswell Viaduct and through Welwyn North station.
  • The King’s Cross and Cambridge service stops in Welwyn North station.
  • Full in-cab digital signalling is being installed on the East Coast Main Line, which could increase the speed of the expresses through the double-track section.

Could the introduction of the Class 387 trains on the Cambridge and King’s Cross service have been made, as it easier to fit in all the services if this one is run by a 110 mph train?

However, the full in-cab digital signalling with a degree of automatic train control could be the solution to this bottleneck on the East Coast Main Line.

  • Trains could be controlled automatically and with great precision between perhaps Hatfield and Stevenage.
  • Some expresses might be slowed to create gaps for the Cambridge and Peterborough services.
  • The Hertford Loop Line is also getting full in-cab digital signalling, so will some services be sent that way?

In Call For ETCS On King’s Lynn Route, I talked about a proposal to improve services on the Fen Line. This was my first three paragraphs.

The title of this post, is the same as that on an article in Edition 849 of Rail Magazine.

The article is based on this document on the Fen Line Users Aoociation web site, which is entitled Joint Response To Draft East Coast Main Line Route Study.

In addition to ETCS, which could improve capacity on the East Coast Main Line, they would also like to see journey time reductions using trains capable of running at 125 mph or faster on the King’s Lynn to Kings Cross route.

My scheduling experience tells me that a better solution will be found, if all resources are similar.

Hence the proposal to run 125 mph trains between King’s Cross and King’s Lynn and probably Ely as well, could be a very good and logical idea.

If the Class 700 trains were increased in speed to 110 mph, the trains through the double-track section of the East Coast Main Line would be.

  • One tph – 110 mph – Class 387 trains
  • Four tph – 110 mph – Class 700 trains
  • Two tph – 125 mph – New trains

Note.

  1. This would probably be an easier mix of trains to digest with the high speed services, through the double-track section.
  2. I like the idea of extending the Ely service to Norwich to give Thetford, Attleborough and Wymondham an improved service to London, Cambridge and Norwich.

The new trains would probably be a version of Hitachi’s Regional Battery Train.

  • It would need to be capable of 125 mph on the East Coast Main Line.
  • If the Ely service were to be extended to Norwich, this section would be on battery power.

There are certainly a lot of possibilities.

But as with on the Midland Main Line, it looks like for efficient operation, the operating speed of the Class 700 trains on the route needs to be increased to at least 110 mph.

Could Faster Class 700 trains Improve Services To Brighton?

These are the Thameslink services that serve Bedford, Cambridge and Peterborough, that I believe could be run more efficiently with trains capable of at running at speeds of at least 110 mph.

  • Bedford and Brighton – Two tph
  • Bedford and Gatwick Airport – Two tph
  • Cambridge and Brighton – Two tph
  • Cambridge and Maidstone East – Two tph
  • Peterborough and Horsham – Two tph

Note.

  1. I have assumed that the Cambridge and King’s Cross service has been extended to Maidstone East as planned.
  2. Eight tph serve Gatwick Airport.
  3. Four tph serve Brighton.

The Gatwick Express services have a frequency of two tph between London Victoria and Brighton calling at Gatwick Airport is already run by 110 mph Class 387 trains.

It would appear that if the Bedford, Cambridge and Peterborough were run by uprated 110 mph Class 700 trains, then this would mean that more 110 mph trains would be running to Gatwick and Brighton and this must surely improve the service to the South Coast.

But it’s not quite as simple as that, as the Cambridge and Maidstone East services will be run by eight-car trains and all the other services by twelve-car trains.

Conclusion

There would appear to be advantages in uprating some or possibly all of the Class 700 trains, so that they can run at 110 mph, as it will increase capacity on the Brighton Main Line, East Coast Main Line and Midland Main Line.

Hitachi Targets Next Year For Testing Of Tri-Mode IET

The title of this post, is the same as that of this article on Rail Magazine.

This is the first two paragraphs.

Testing of a five-car Hitachi Class 802/0 tri-mode unit will begin in 2022, and the train could be in traffic the following year.

It is expected that the train will save more than 20% of fuel on Great Western Railway’s London Paddington-Penzance route.

This is the Hitachi infographic, which gives the train’s specification.

I have a few thoughts and questions.

Will The Batteries Be Charged At Penzance?

Consider.

  • It is probably not a good test of customer reaction to the Intercity Tri-Mode Battery Train, if it doesn’t work on batteries in stations through Cornwall.
  • Every one of the eight stops in Cornwall will need an amount of battery power.
  • London trains seem to take at least half-an-hour to turn round at Penzance.
  • London trains seem to take around 7-13 minutes for the stop at Plymouth.

So I think, that batteries will probably need to be charged at Penzance and possibly Plymouth, to achieve the required battery running,

There is already sufficient time in the timetable.

A charging facility in Penzance station would be a good test of Hitachi’s method to charge the trains.

Will Hyperdrive Innovation’s Battery Pack Be A Simulated Diesel Engine?

At the age of sixteen, for a vacation job, I worked in the Electronics Laboratory at Enfield Rolling Mills.

It was the early sixties and one of their tasks was at the time replacing electronic valve-based automation systems with new transistor-based systems.

The new equipment had to be compatible to that which it replaced, but as some were installed in dozens of places around the works, they had to be able to be plug-compatible, so that they could be quickly changed. Occasionally, the new ones suffered infant-mortality and the old equipment could just be plugged back in, if there wasn’t a spare of the new equipment.

So will Hyperdrive Innovation’s battery-packs have the same characteristics as the diesel engines that they replace?

  • Same instantaneous and continuous power output.
  • Both would fit the same mountings under the train.
  • Same control and electrical power connections.
  • Compatibility with the trains control computer.

I think they will as it will give several advantages.

  • The changeover between diesel engine and battery pack could be designed as a simple overnight operation.
  • Operators can mix-and-match the number of diesel engines and battery-packs to a given route.
  • As the lithium-ion cells making up the battery pack improve, battery capacity and performance can be increased.
  • If the computer, is well-programmed, it could reduce diesel usage and carbon-emissions.
  • Driver conversion from a standard train to one equipped with batteries, would surely be simplified.

As with the diesel engines, all battery packs could be substantially the same across all of Hitachi’s Class 80x trains.

How Many Trains Can Eventually Be Converted?

Great Western Railway have twenty-two Class 802/0 trains.

  • They are five-cars.
  • They have three diesel engines in cars 2, 3 and 4.
  • They have a capacity of 326 passengers.
  • They have an operating speed of 125 mph on electrification.
  • They will have an operating speed of 140 mph on electrification with in-cab ERTMS digital signalling.
  • They have an operating speed of 110 mph on diesel.
  • They can swap between electric and diesel mode at line speed.

Great Western Railway also have these trains that are similar.

  • 14 – nine-car Class 802/1 trains
  • 36 – five-car Class 800/0 trains
  • 21 – nine-car Class 800/3 trains

Note.

  1. The nine-car trains have five diesel engines in cars 2,3, 5, 7 and 8
  2. All diesel engines are similar, but those in Class 802 trains are more powerful, than those in Class 800 trains.

This is a total of 93 trains with 349 diesel engines.

In addition, there are these similar trains in service or on order with other operators.

Note.

  1. Class 801 trains have one diesel engine for emergency power.
  2. Class 803 trains have no diesel engines, but they do have a battery for emergency power.
  3. Class 805 trains have an unspecified number of diesel engines. I will assume three.
  4. Class 807 trains have no batteries or diesel engines.
  5. Class 810 trains have four diesel engines.

This is a total  of 150 trains with 395 diesel engines.

The Rail Magazine finishes with this paragraph.

Hitachi believes that projected improvements in battery technology, particularly in power output and charge, could enable diesel engines to be incrementally replaced on long-distance trains.

Could this mean that most diesel engines on these Hitachi trains are replaced by batteries?

Five-Car Class 800 And Class 802 Trains

These trains are mainly regularly used to serve destinations like Bedwyn, Cheltenham, Chester, Harrogate, Huddersfield, Hull, Lincoln, Oxford and Shrewsbury, which are perhaps up to fifty miles beyond the main line electrification.

  • They have three diesel engines, which are used when there is no electrification.
  • I can see many other destinations, being added to those reached by the Hitachi trains, that will need similar trains.

I suspect a lot of these destinations can be served by five-car Class 800 and Class 802 trains, where a number of the diesel engines are replaced by batteries.

Each operator would add a number of batteries suitable for their routes.

There are around 150 five-car bi-mode Hitachi trains in various fleets in the UK.

LNER’s Nine-Car Class 800 Trains

These are mainly used on routes between London and the North of Scotland.

In LNER Seeks 10 More Bi-Modes, I suggested that to run a zero-carbon service to Inverness and Aberdeen, LNER might acquire rakes of carriages hauled by zero-carbon hydrogen electric locomotives.

  • Hydrogen power would only be used North of the current electrification.
  • Scotland is looking to have plenty of hydrogen in a couple of years.
  • No electrification would be needed to be erected in the Highlands.
  • InterCity 225 trains have shown for forty years, that locomotive-hauled trains can handle Scottish services.
  • I also felt that the trains could be based on a classic-compatible design for High Speed Two.

This order could be ideal for Talgo to build in their new factory at Longannet in Fife.

LNER’s nine-car Class 800 trains could be converted to all-electric Class 801 trains and/or moved to another operator.

There is also the possibility to fit these trains with a number of battery packs to replace some of their five engines.

If the planned twenty percent fuel savings can be obtained, that would be a major improvement on these long routes.

LNER’s Class 801 Trains

These trains are are all-electric, but they do have a diesel engine for emergencies.

Will this be replaced by a battery pack to do the same job?

  • Battery packs are probably cheaper to service.
  • Battery packs don’t need diesel fuel.
  • Battery packs can handle regenerative braking and may save electricity.

The installation surely wouldn’t need too much test running, as a lot of testing will have been done in Class 800 and Class 802 trains.

East Coast Trains’ Class 803 Trains

These trains have a slightly different powertrain to the Class 801 trains. Wikipedia says this about the powertrain.

Unlike the Class 801, another non-bi-mode AT300 variant which despite being designed only for electrified routes carries a diesel engine per unit for emergency use, the new units will not be fitted with any, and so would not be able to propel themselves in the event of a power failure. They will however be fitted with batteries to enable the train’s on-board services to be maintained, in case the primary electrical supplies would face a failure.

The trains are in the process of being built, so I suspect batteries can be easily fitted.

Could it be, that all five-car trains are identical body-shells, already wired to be able to fit any possible form of power? Hitachi have been talking about fitting batteries to their trains since at least April 2019, when I wrote, Hitachi Plans To Run ScotRail Class 385 EMUs Beyond The Wires.

  • I suspect that Hitachi will use a similar Hyperdrive Innovation design of battery in these trains, as they are proposing for the Intercity Tri-Mode Battery Train.
  • If all trains fitted with diesel engines, use similar MTU units, would it not be sensible to only use one design of battery pack?
  • I suspect, that as the battery on a Class 803 train, will be mainly for emergency use, I wouldn’t be surprised to see that these trains could be the first to run in the UK, with a battery.
  • The trains would also be simpler, as they are only battery-electric and not tri-mode. This would make the software easier to develop and test.

If all trains used the same battery pack design, then all features of the pack, would be available to all trains to which it was fitted.

Avanti West Coast’s Class 805 Trains

In Hitachi Trains For Avanti, which was based on an article with the same time in the January 2020 Edition of Modern Railways, I gave this quote from the magazine article.

Hitachi told Modern Railways it was unable to confirm the rating of the diesel engines on the bi-modes, but said these would be replaceable by batteries in future if specified.

Note.

  1. Hitachi use diesel engines with different ratings in Class 800 and Class 802 trains, so can probably choose something suitable.
  2. The Class 805 trains are scheduled to be in service by 2022.
  3. As they are five-cars like some Class 800 and Class 802 trains will they have the same basic structure and a powertrain with three diesel engines in cars 2, 3 and 4?

I think shares a basic structure and powertrain will be very likely, as there isn’t enough time to develop a new train.

I can see that as Hitachi and Great Western Railway learn more about the performance of the battery-equipped Class 802 trains on the London and Penzance route, that batteries could be added to Avanti West Coast’s Class 805 trains. After all London Euston and North Wales and London Paddington and Cornwall are routes with similar characteristics.

  • Both routes have a high speed electrified section out of London.
  • They have a long section without electrification.
  • Operating speeds on diesel are both less than 100 mph, with sections where they could be as low as 75 mph.
  • The Cornish route has fifteen stops and the Welsh route has seven, so using batteries in stations will be a welcome innovation for passengers and those living near the railway.

As the order for the Avanti West Coast trains was placed, whilst Hitachi were probably designing their battery electric upgrade to the Class 800 and Class 802 trains, I can see batteries in the Class 805 trains becoming an early reality.

In Hitachi Trains For Avanti, I also said this.

Does the improvement in powertrain efficiency with smaller engines running the train at slower speeds help to explain this statement from the Modern Railways article?

Significant emissions reduction are promised from the elimination of diesel operation on electrified sections as currently seen with the Voyagers, with an expected reduction in CO2 emissions across the franchise of around two-thirds.

That is a large reduction, which is why I feel, that efficiency and batteries must play a part.

Note.

  1. The extract says that they are expected savings not an objective for some years in the future.
  2. I have not done any calculations on how it might be achieved, as I have no data on things like engine size and expected battery capacity.
  3. Hitachi are aiming for 20 % fuel and carbon savings on London Paddington and Cornwall services.
  4. Avanti West Coast will probably only be running Class 805 trains to Chester, Shrewsbury and North Wales.
  5. The maximum speed on any of the routes without electrification is only 90 mph. Will less powerful engines be used to cut carbon emissions?

As Chester is 21 miles, Gobowen is 46 miles, Shrewsbury is 29.6 miles and Wrexham General is 33 miles from electrification, could these trains have been designed with two diesel engines and a battery pack, so that they can reach their destinations using a lot less diesel.

I may be wrong, but it looks to me, that to achieve the expected reduction in CO2 emissions, the trains will need some radical improvements over those currently in service.

Avanti West Coast’s Class 807 Trains

In the January 2020 Edition of Modern Railways, is an article, which is entitled Hitachi Trains For Avanti.

This is said about the ten all-electric Class 807 trains for Birmingham, Blackpool and Liverpool services.

The electric trains will be fully reliant on the overhead wire, with no diesel auxiliary engines or batteries.

It may go against Hitachi’s original design philosophy, but not carrying excess weight around, must improve train performance, because of better acceleration.

I believe that these trains have been designed to be able to go between London Euston and Liverpool Lime Street stations in under two hours.

I show how in Will Avanti West Coast’s New Trains Be Able To Achieve London Euston and Liverpool Lime Street In Two Hours?

Consider.

  • Current London Euston and Liverpool Lime Street timings are two hours and thirteen or fourteen minutes.
  • I believe that the Class 807 trains could perhaps be five minutes under two hours, with a frequency of two trains per hour (tph)
  • I have calculated in the linked post, that only nine trains would be needed.
  • The service could have dedicated platforms at London Euston and Liverpool Lime Street.
  • For comparison, High Speed Two is promising one hour and thirty-four minutes.

This service would be a Marketing Manager’s dream.

I can certainly see why they won’t need any diesel engines or battery packs.

East Midland Railway’s Class 810 Trains

The Class 810 trains are described like this in their Wikipedia entry.

The Class 810 is an evolution of the Class 802s with a revised nose profile and facelifted end headlight clusters, giving the units a slightly different appearance. Additionally, there will be four diesel engines per five-carriage train (versus three on the 800s and 802s), and the carriages will be 2 metres (6.6 ft) shorter.

In addition, the following information has been published about the trains.

  • The trains are expected to be capable of 125 mph on diesel.
  • Is this speed, the reason for the fourth engine?
  • It is planned that the trains will enter service in 2023.

I also suspect, that like the Class 800, Class 802 and Class 805 trains, that diesel engines will be able to be replaced with battery packs.

Significant Dates And A Possible Updating Route For Hitachi Class 80x Trains

I can put together a timeline of when trains are operational.

  • 2021 – Class 803 trains enter service.
  • 2022 – Testing of prototype Intercity Tri-Mode Battery Train
  • 2022 – Class 805 trains enter service.
  • 2022 – Class 807 trains enter service.
  • 2023 – First production Intercity Tri-Mode Battery Train enters service.
  • 2023 – Class 810 trains enter service.

Note.

  1. It would appear to me, that Hitachi are just turning out trains in a well-ordered stream from Newton Aycliffe.
  2. As testing of the prototype Intercity Tri-Mode Battery Train proceeds, Hitachi and the operators will learn how, if batteries can replace some or even all of the diesel engines, the trains will have an improved performance.
  3. From about 2023, Hitachi will be able to design tri-mode trains to fit a customer’s requirements.
  4. Could the powertrain specification of the Class 810 trains change, in view of what is shown by the testing of the prototype Intercity Tri-Mode Battery Train?
  5. In parallel, Hyperdrive Innovation will be building the battery packs needed for the conversion.

Batteries could be fitted to the trains in three ways,

  • They could be incorporated into new trains on the production line.
  • Batteries could be fitted in the depots, during a major service.
  • Trains could be returned to Newton Aycliffe for battery fitment.

Over a period of years as many trains as needed could be fitted with batteries.

Conclusion

I believe there is a plan in there somewhere, which will convert many of Hitachi’s fleets of trains into tri-mode trains with increased performance, greater efficiency and less pollution and carbon emissions.
