The Anonymous Widower

LNER’s Middlesbrough And London Service Starts On December 13th

Tucked at the bottom of the article entitled LNER Tickets For Christmas Getaway in Edition 939 of Rail Magazine, there is this paragraph separated from the article by a sole bullet point.

LNER has confirmed that from December 13 it will run a new weekday service between London King’s Cross and Middlesbrough.

It has already made an appearance on Real Time Trains and I can find the following details.

  • There will be one train per day (tpd)
  • 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.

These are my thoughts.

Trains Per Day

One train per day, is obviously an introductory service and like services to Harrogate and Lincoln, the number of services will ramp up to perhaps four or five tpd, if the demand is there and the paths and trains are available.

Journey Times

Consider

  • The Southbound journey takes three hours and fourteen minutes with a time of two hours and nine minutes between York and King’s Cross
  • The Northbound journey takes two hours and fifty-three minutes with a time of one hour and fifty-six minutes between King’s Cross and York.
  • Some services between King’s Cross and York are as fast as one hour and forty-eight minutes.
  • Middlesbrough and York seems to take around 52-58 minutes.
  • These Middlesbrough and York timings are consistent with TransPennine Express.
  • Digital signalling could offer savings in journey time between York and London.

I think it is very likely as the timetable improves, that timings between Middlesbrough and London could be around two hours and forty minutes.

Electrification

The route is fully electrified except for between Middlesbrough and Longlands Junction, where it joins the electrification of the East Coast Main Line, which is a distance of twenty-two miles.

Hitachi are developing a battery-train, which they call the Hitachi Intercity Tri-Mode Battery Train, which is described in this Hitachi infographic.

Note.

  1. LNER’s current Class 800 trains will probably be able to be converted to this train.
  2. A range on battery power of upwards of forty miles would be expected.

If the range on battery-power can be stretched to perhaps sixty miles, this train should be capable of serving Middlesbrough without the need for any extra charging at the terminus.

I am sure Hitachi would like to see their battery-electric trains running between King’s Cross and Middlesbrough, as it would be an ideal route on which to show the trains to prospective customers, given that their factory is at Newton Aycliffe.

Conclusion

This could be good demonstration battery-electric service for Hitachi and LNER.

ORR’s Policy On Third Rail DC Electrification Systems

The title of this post is the same as that of a document I downloaded from this page on the Office of Rail and Road web site.

It is one of the most boring legal documents, that I have ever read and I have read a few in my time.

As I read it, effectively it says that new third-rail electrification is banned because of Health and Safety issues, which take precedence.

But only once in the document is new technology mentioned, that might make third-rail safer and that is a reference to the Docklands Light Railway, where the third rail is shielded.

I am an Electrical Engineer and I was designing safety systems for heavy industrial guillotines at fifteen as a vacation job in a non-ferrous metals factory.

One design of an ideal electric railway would have battery-electric trains, that were charged in stations by third-rail. The third-rail would only be energised, when a train was over the top and needed to be charged. In effect the train would act as an all-enclosing guard to the conductor rail.

Electrification Of The West Of England Main Line

The West of England Main Line runs between Basingstoke and Exeter via Salisbury. It is one of the longest, if not the longest main lines in England, that is not electrified.

It would probably need to be electrified with 750 VDC third-rail electrification, as that standard is used between London Waterloo and Basingstoke.

In Solving The Electrification Conundrum, I described a system being developed by Hitachi, that would use battery-electric trains that were charged by short sections of electrified line every fifty miles or so. For reasons of ease of installation and overall costs, these short sections of electrification could be third-rail, that was electrically dead unless a train was connected and needed charging. These electrified sections could also be in stations, where entry on to the railway is a bit more restricted.

Conclusion

The Office of Rail and Road needs to employ a few more engineers with good technical brains, rather than ultra-conservative risk-averse lawyers.

As a sad footnote, I live in East London, where trespassers are regularly electrocuted on the railway. But usually, it is when idiots are travelling on top of container trains  and inadvertently come into contact with the overhead electrification.

Hitachi Class 800 Train Or Pendelino?

I have had several day trips on hot days on Hitachi Class 800 trains or similar since the pandemic started to places like Bristol, Cardiff, Doncaster, Grantham, Hull and Westbury.

I’ve done a couple of trips in Pendelinos or Class 390 trains to Birmingham and Liverpool.

In addition, I’ve taken a couple of trips on other trains to Corby, Ipswich, Sheffield and Southampton.

It must have been sometime in 2018, when I took one of the first Pendelinos to Blackpool after that station was first electrified.

It was a journey on which I first noticed being unwell on a Pendelino. I travelled in First and remember complaining to the steward and said that some taff didn’t like the trains after their recent air-conditioning upgrade.

Perhaps, Virgin Trains chose a system that would be cheaper to run and it is not on a par with the quality systems used by Bombardier and Hitachi?

I have been testing the atmosphere in trains like a Class 345, 378 or 800 and the temperature is usually 25-26 °C and a humidity around 40-60 %. I haven’t tested a Pendolino yet!

I must say, I’ve never ended up in hospital after a trip out of London, except after a recent trip on a Pendelino to Birmingham, that I wrote about in A Mysterious Attack On My Body.

In that post, I also said this about the Pendelinos.

I had travelled between Euston  and Wolverhampton on my least favourite trains – Alstom’s Class 390 trains.

    • The seats don’t align well with the windows.
    • The trains are cramped because of all the tilting mechanism.

These trains must a nightmare for anybody taller than my 1.70 metres or heavier than my sixty-two kilos.

But the biggest problem of these Pendolino trains is that Alstom updated the air-conditioning a few years ago for Virgin a few years ago and I find the air inside too dry.

So in future, I won’t be travelling on a Pendelino, unless I travel in First!

I also can’t wait until Avanti West Coast get new Hitachi Class 807 trains on the Euston and Liverpool route!

Vivarail At COP26

This press release from Network Rail is entitled Network Rail And Porterbrook To Showcase Britain’s Green Trains Of The Future At COP26.

These two paragraphs are from the end of the first section of the press release.

It is envisaged that the HydroFLEX may also be used to transport visitors to see the Zero Emission Train, Scotland’s first hydrogen powered train.

Network Rail is also in the earlier stages of planning a similar event with Vivarail to bring an operational battery train to COP26.

Vivarail have taken battery trains to Scotland before for demonstration, as I wrote about in Battery Class 230 Train Demonstration At Bo’ness And Kinneil Railway.

Will other train companies be joining the party?

Alstom

It looks like Alstom’s hydrogen-powered Class 600 train will not be ready for COP26.

But I suspect that the French would not like to be upstaged by a rolling stock leasing company and a university on the one hand and a company with scrapyard-ready redundant London Underground trains on the other.

I think, they could still turn up with something different.

They could drag one of their Coradia iLint trains through the Channel Tunnel and even run it to Scotland under hydrogen power, to demonstrate the range of a hydrogen-powered train.

Alstom have recently acquired Bombardier’s train interests in the UK and there have been rumours of a fleet of battery-electric Electrostars, even since the demonstrator ran successfully in 2015. Will the prototype turn up at COP26?

Alstom’s UK train factory is in Widnes and I’ve worked with Liverpudlians and Merseysiders on urgent projects and I wouldn’t rule out the Class 600 train making an appearance.

CAF

Spanish train company; CAF, have impressed me with the speed, they have setup their factory in Newport and have delivered a total of well over a hundred Class 195 and Class 331 trains to Northern.

I wrote Northern’s Battery Plans, in February 2020, which talked about adding a fourth-car to three-car Class 331 trains, to create a battery-electric Class 331 train.

Will the Spanish bring their first battery-electric Class 331 train to Glasgow?

I think, they just might!

After all, is there a better place for a train manufacturer looking to sell zero-carbon trains around the world to announce, their latest product?

Hitachi

A lot of what I have said for Alstom and CAF, could be said for Hitachi.

Hitachi have announced plans for two battery-electric trains; a Regional Battery Train and an Intercity Tri-Mode Battery Train.

I doubt that either of these trains could be ready for COP26.

But last week, I saw the new Hitachi Class 803 train speeding through Oakleigh Park station.

This is not a battery-electric train, where battery power can be used for traction, but according to Wikipedia and other sources, it is certainly an electric train fitted with batteries to provide hotel power for the train, when the overhead electrification fails.

Are these Class 803 trains already fitted with their batteries? And if they are, have they been tested?

And who is building the batteries for the Class 803 trains?

The traction batteries for Hitachi’s two battery-electric trains are to be produced by Hyperdrive Innovation of Sunderland, which is not far from Hitachi’s train factory at Newton Aycliffe.

As an engineer, I would suspect that a well-respected company like Hyperdrive Innovation, can design a battery-pack that plugs in to Hitachi’s trains, as a diesel engine would. I would also suspect that a good design, would allow an appropriate size of battery for the application and route.

I feel it is very likely, that all batteries for Hitachi’s UK trains will be designed and build by Hyperdrive Innovation.

If that is the case and the Class 803 trains are fitted with batteries, then Hitachi can be testing the battery systems.

This document on the Hitachi Rail web site, which is entitled Development of Class 800/801 High-speed Rolling Stock for UK Intercity Express Programme, gives a very comprehensive description of the electrical and computer systems of the Hitachi trains.

As an engineer and a computer programmer, I believe that if Hyperdrive Innovation get their battery design right and after a full test program, that Hitachi could be able to run battery-electric trains based on the various Class 80x trains.

It could be a more difficult task to fit batteries to Scotland’s Class 385 trains, as they are not fitted with diesel engines in any application. Although, the fitting of diesel engines may be possible in the global specification for the train.

It is likely that these trains could form the basis of the Regional Battery Train, which is described in this infographic.

Note.

  1. The Class 385 and Regional Battery trains are both 100 mph trains.
  2. Class 385 and Class 80x trains are all members of Hitachi’s A-Train family.
  3. Regional Battery trains could handle a lot of unelectrified routes in Scotland.

I wouldn’t be surprised to see Hitachi bring a battery-equipped train to COP26, if the Class 803 trains have a successful introduction into service.

Siemens

Siemens have no orders to build new trains for the national rail network in the UK.

But there are plans by Porterbrook and possibly other rolling stock leasing companies and train operators to convert some redundant Siemens-built trains, like Class 350 trains, into battery-electric trains.

According to Wikipedia, Siemens upgraded East Midlands Railways, Class 360 trains to 110 mph operation, at their Kings Heath Depot in Northampton.

Could Siemens be updating one of the Class 350 trains, that are serviced at that depot, to a prototype battery-electric Class 350 train?

Stadler

Stadler have a proven design for diesel-electric, battery-electric and hydrogen trains, that they sell all over the world.

In the UK, the only ones in service are Greater Anglia’s Class 755 trains, which are diesel-electric bi-mode trains.

The picture shows one of these trains at Ipswich.

  • They are 100 mph trains.
  • Diesel, battery or hydrogen modules can be inserted in the short PowerPack car in the middle of the train.
  • Diesel-battery-electric versions of these trains have been sold for operation in Wales.
  • The interiors of these trains are designed for both short journeys and a two-hour run.

There is a possibility, that these trains will be upgraded with batteries. See Battery Power Lined Up For ‘755s’.

Conclusion

Times will be interesting in Glasgow at COP26!

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.

£100m Station Revamp Could Double Local Train Services

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

This is the opening paragraph.

Officials behind plans for a £100m-plus transformation of Darlington’s Bank Top Station have confirmed it will remain the only one on the East Coast Mainline without a platform specifically for the London to Scotland service.

Darlington station has made various appearances in my life, all of which have been pleasurable ones.

I went several times to ICI’s Wilton site on Teesside in the 1970s, when the route to London was worked by the iconic Class 55 locomotives or Deltics.

I wrote about one memorable trip home from Darlington in The Thunder of Three-Thousand Three-Hundred Horses.

Over the years, I also seem to have had several clients for my computing skills in the area, including the use of my data analysis software; Daisy at Cummins Engines in the town.

And lately, it’s been for football at Middlesbrough to see Ipswich play, where I’ve changed trains. Sometimes, Town even won.

The improvements planned for the station are two-fold.

Improvement Of Local Services

This paragraph from Wikipedia, sums up the local train services on the Tees Valley Line between Saltburn and Bishop Auckland via Darlington, Middlesbrough and Redcar.

Northern run their Tees Valley line trains twice hourly to Middlesbrough, Redcar and Saltburn (hourly on Sundays), whilst the Bishop Auckland branch has a service every hour (including Sundays). The company also operates two Sundays-only direct trains to/from Stockton and Hartlepool.

If ever a route needed improvement it is this one.

This paragraph from the Northern Echo article, outlines the plans for Darlington station.

The meeting was also told the overhaul, which will see new platforms, a new station building, parking and an interchange for passengers, alongside other improvements, would also double capacity on Tees Valley and Bishop Auckland lines, meaning four trains an hour on the former and two trains an hour on the latter.

I also believe that the route is a shoe-in for zero-carbon services; hydrogen or battery electric.

Hydrogen Trains On Teesside

In Fuelling The Change On Teesside Rails, I discuss using hydrogen powered trains for the lines in the area and they could certainly provide services on more than just the Tees Valley Line.

The hydrogen powered trains would probably be this Alstom Breeze.

They would appear to be in pole position to change the image of Teesside’s trains.

Battery Electric Trains On Teesside

But I suspect. that an Anglo-Japanese partnership, based in the North-East could have other ideas.

  • Hitachi have a train factory at Newton Aycliffe on the Tees Valley Line.
  • Hyperdrive Innovation design and produce battery packs for transport and mobile applications in Sunderland.

The two companies have launched the Regional Battery Train, which is described in this Hitachi infographic.

Note than 90 kilometres is 56 miles, so the train has a very useful range.

Hitachi have talked about fitting batteries to their express trains to serve places like Middlesbrough, Redcar and Sunderland with zero-carbon electric services.

But their technology can also be fitted to their Class 385 trains and I’m sure that Scotland will order some battery-equipped Class 385 trains to expand their vigorous electric train network.

Both Scotland and Teesside will need to charge their battery trains.

Example distances on Teesside include.

  • Darlington and Saltburn – 28 miles
  • Darlington and Whitby – 47 miles
  • Darlington and Bishop Auckland – 12 miles

The last route would be possible on a full battery, but the first two would need a quick battery top-up before return.

So there will need to be strategically-placed battery chargers around the North-East of England. These could include.

  • Hexham
  • Nunthorpe
  • Redcar or Saltburn – This would also be used by TransPennine Express’s Class 802 trains, if they were to be fitted with batteries.
  • Whitby

If Grand Central did the right thing and ran battery electric between London and Sunderland, there would probably be a need for a battery charger at Sunderland.

It appears that Adrian Shooter of Vivarail has just announced a One-Size-Fits-All Fast Charge system, that has been given interim approval by Network Rail.

I discuss this charger in Vivarail’s Plans For Zero-Emission Trains, which is based on a video on the Modern Railways web site.

There is more about Vivarail’s plans in the November 2020 Print Edition of the magazine, where this is said on page 69.

‘Network Rail has granted interim approval for the fast charge system and wants it to be the UK’s standard battery charging system’ says Mr. Shooter. ‘We believe it could have worldwide implications.’

I believe that Hitachi and Hyperdrive Innovation, with a little bit of help from friends in Seaham, can build a battery-electric train network in the North-East.

The Choice Between Hydrogen And Battery Electric

Consider.

  • The hydrogen trains would need a refuelling system.
  • The battery electric trains would need a charging structure, which could also be used by other battery electric services to and from the North-East.
  • No new electrification or other infrastructure would be needed.
  • If a depot is needed for the battery electric trains, they could probably use the site at Lackenby, that has been identified as a base for the hydrogen trains.

Which train would I choose?

I think the decision will come down to politics, money and to a certain extent design, capacity and fuel.

  • The Japanese have just signed a post-Brexit trade deal and France or rather the EU hasn’t.
  • The best leasing deal might count for a lot.
  • Vivarail have stated that batteries for a battery electric train, could be leased on a per mile basis.
  • The Hitachi train will be a new one and the Alstom train will be a conversion of a thirty year old British Rail train.
  • The Hitachi train may well have a higher passenger capacity, as there is no need for the large hydrogen tank.
  • Some people will worry about sharing the train with a large hydrogen tank.
  • The green credentials of both trains is not a deal-breaker, but will provoke discussion.

I feel that as this is a passenger train, that I’m leaning towards a battery electric train built on the route.

An Avoiding Line Through Darlington

The Northern Echo also says this about track changes at the station.

A meeting of Darlington Borough Council’s communities and local services scrutiny committee was told a bus lane-style route off the mainline at the station would enable operators to run more high-speed services.

Councillors heard that the proposed track changes would enable very fast approaches to Darlington and allow other trains to pass as East Coast Mainline passengers boarded.

Some councillors seem to be unhappy about some trains passing through the station without stopping.

Are their fears justified?

This Google Map shows Darlington station.

Note.

  1. The station has two long platforms and two South-facing bay platforms.
  2. There is plenty of space.
  3. There already appear to be a pair of electrified avoiding lines on the Eastern side of the station.

Wikipedia also says this about how Darlington station will be changed by High Speed Two.

The new high speed rail project in the UK, High Speed 2, is planned to run through Darlington once Phase 2b is complete and will run on the existing East Coast Main Line from York and Newcastle. Darlington Station will have two new platforms built for the HS2 trains on the Main Line, as the station is built just off the ECML to allow for freight services to pass through.

This would appear to suggest that the two current avoiding lines will be turned into high speed platforms.

Current High Speed Services At Darlington

The current high speed services at Darlington are as follows.

  • LNER – two trains per hour (tph) – London Kings Cross and Edinburgh
  • Cross Country – one tph – Plymouth and Edinburgh or Glasgow
  • Cross Country – one tph – Southampton and Newcastle
  • TransPennine Express – one tph – Liverpool and Edinburgh
  • TransPennine Express – one tph – Manchester Airport and Newcastle

Northbound, this gives eight tph to Newcastle and four tph to Edinburgh

East Coast Trains

East Coast Trains‘s services are not planned to stop at Darlington.

High Speed Two Trains

Darlington is planned to be served by these High Speed Two trains.

  • 1 tph – Birmingham Curzon Street and Newcastle via East Midlands Hub, York and Durham
  • 1 tph – London Euston and Newcastle via Old Oak Common and York.

Both will be 200 metre High Speed Two Classic-Compatible trains

Northbound, this gives ten tph to Newcastle and four tph to Edinburgh.

As the Eastern Leg of High Speed Two has some spare capacity, I suspect there could be other services through Darlington.

Improvements To The East Coast Main Line

If you look at the East Coast Main Line between Doncaster and Newcastle, the route is a mixture of two and four-track railway.

  • Between Doncaster and York, there are two tracks
  • Between York and Northallerton, there are four tracks
  • Between Northallerton and Darlington, there are two tracks
  • North of Darlington, the route is mainly two tracks.

I have flown my virtual helicopter along much of the route and I can say this about it.

  • Much of the route is through agricultural land, and where absolutely necessary extra tracks could possibly be added.
  • The track is more-or-less straight for large sections of the route.
  • Routes through some towns and cities, are tightly hemmed in by houses.

I also believe that the following developments will happen to the whole of the East Coast Main Line before High Speed Two opens.

  • Full ERTMS in-cab digital signalling will be used on all trains on the route.
  • The trains will be driven automatically, with the driver watching everything. Just like a pilot in an airliner!
  • All the Hitachi Class 80x trains used by operators on the route, will be able to operate at up to 140 mph, once this signalling and some other improvements have been completed.
  • All level crossings will have been removed.
  • High Speed Two is being built using slab track, as I stated in HS2 Slab Track Contract Awarded. I suspect some sections of the East Coast Main Line, that are used by High Speed Two services, will be upgraded with slab track to increase performance and reduce lifetime costs.

Much of the East Coast Main Line could become a 140 mph high speed line, as against High Speed Two, which will be a 225 mph high speed line.

This will mean that all high speed trains will approach Darlington and most other stations on the route, at 140 mph.

Trains will take around a minute to decelerate from or accelerate to 140 mph and if the station stop took a minute, the trains will be up to speed again in just three minutes. In this time, the train would have travelled two-and-a-half miles.

Conclusion

I think that this will happen.

  • The Tees Valley Line trains will be greatly improved by this project.
  • Trains will generally run at up to 140 mph on the East Coast Main Line, under full digital control, like a slower High Speed Two.
  • There will be two high speed platforms to the East of the current station, where most if not all of the High Speed Two, LNER and other fast services will stop.
  • There could be up to 15 tph on the high speed lines.

With full step-free access between the high speed and the local platforms in the current station, this will be a great improvement.

How Many Trains Are Needed To Run A Full Service On High Speed Two?

The latest High Speed Two schedule was published in the June 2020 Edition of Modern Railways.

The Two Train Classes

Two separate train classes have been proposed for High Speed Two.

Full-Size – Wider and taller trains built to a European loading gauge, which would be confined to the high-speed network (including HS1 and HS2) and other lines cleared to their loading gauge.

Classic-Compatible – Conventional trains, capable of high speed but built to a British loading gauge, permitting them to leave the high speed track to join conventional routes such as the West Coast Main Line, Midland Main Line and East Coast Main Line.

The Wikipedia entry for High Speed Two has a section entitled Rolling Stock, where this is said about the design.

Both types of train would have a maximum speed of at least 360 km/h (225 mph) and a length of 200 metres (660 ft); two units could be joined together for a 400-metre (1,300 ft) train. It has been reported that these longer trains would have approximately 1,100 seats.

These are some of my thoughts.

Seating Density

I would assume that this means that a single 200 metre train, will have a capacity of approximately 550 seats or a density of 2.75 seats per metre. How does that compare with other trains?

  • 9-car Class 801 train – 234 metres – 611 seats – 2.61 seats/metre
  • 7-car Class 807 train – 182 metres – 453 seats – 2.49 seats/metre
  • 9-car Class 390 train  – 217.5 metres – 469 seats – 2.16 seats/metre
  • 11-car Class 390 train  – 265.3 metres – 589 seats – 2.22 seats/metre
  • 12-car Class 745/1 train – 236.6 metres – 767 seats – 3.24 seats/metre
  • 16-car Class 374 train – 390 metres – 902 seats – 2.31 seats/metre

What I find strange with these figures, is that I feel most crowded and cramped in a Class 390 train. Could this be because the Pendelino trains are eighteen years old and train interior design has moved on?

But I always prefer to travel in a Hitachi Class 80x train or a Stadler Class 745 train.

I very much feel that a seating density of 2.75 seats per metre, designed using some of the best modern practice, could create a train, where travelling is a very pleasant experience.

Step-Free Access

I have travelled in high speed trains all over Europe and have yet to travel in one with step-free access.

Surely, if Stadler can give their trains step-free access everybody can.

The pictures shows step-free access on Stadler Class 745 and Class 755 trains.

If I turned up pushing a friend in a wheelchair, would I be able to push them in easily? Or better still will they be able to wheel themselves in?

A Greater Anglia driver once said to me, that they never have to wait anymore for wheelchairs to be loaded.

So surely, it is in the train operator’s interest to have step-free access, if it means less train delays.

Double-Deck Trains

In my view double-deck trains only have one only good feature and that is the ability to see everything, if you have a well-designed window seat.

I may be seventy-three, but I am reasonably fit and only ever travel on trains with airline-sized hand baggage. So I don’t find any problem travelling upstairs on a double-deck bus or train!

But it could have been, so very different, if my stroke had been a bit worse and left me blind or in a wheelchair for life.

I have seen incidents on the Continent, which have been caused by double-deck trains.

  • A lady of about eighteen in trying to get down with a heavy case dropped it. Luckily it only caused the guy she was travelling with, to roll unhurt down the stairs.
  • Luggage is often a problem on Continental trains because of the step-up into the train and access is worse on double deck trains.
  • I also remember on a train at Leipzig, when several passengers helped me lift a guy and his wheelchair out of the lower deck of a double-deck train, which was lower than the platform, as they often are with double-deck trains.

I am not totally against double-deck trains, but they must be designed properly.

Consider.

  • High Speed Two’s Full-Size trains will only use London Euston, Old Oak Common, Birmingham Interchange, Birmingham Curzon Street, Manchester Airport, Manchester Piccadilly, East Midlands Hub and Leeds stations.
  • All stations used by Full-Size trains will be brand-new or substantially rebuilt stations.
  • Someone sitting in a wheelchair surely has the same right to a view from the top-deck of a double-deck train as anybody else.
  • Jumbo jets seemed to do very well without a full-length top-deck.
  • The A 380 Superjumbo has been designed so that entry and exit on both decks is possible.

I feel if High Speed Two want to run double-deck trains, an elegant solution can surely be found.

A Crude Estimate On The Number Of Trains

This is my crude estimate to find out how many trains, High Speed Two will need.

Western Leg

These are the services for the Western Leg between London , Birmingham, Liverpool, Manchester, Edinburgh and Glasgow.

  • Train 1 – London Euston and Birmingham Curzon Street – 400 metre Full-Size – 45 minutes – 2 hour Round Trip – 4 trains
  • Train 2 – London Euston and Birmingham Curzon Street – 400 metre Full-Size – 45 minutes – 2 hour Round Trip – 4 trains

  • Train 10 – London Euston and Edinburgh – Classic Compatible – 3 hours 48 minutes – 8 hour Round Trip – 8 trains
  • Train 10 – London Euston and Glasgow – Classic Compatible – 3 hours 40 minutes – 8 hour Round Trip – 8 trains
  • Train 11 – London Euston and Edinburgh – Classic Compatible – 3 hours 48 minutes – 8 hour Round Trip – 8 trains
  • Train 11 – London Euston and Glasgow – Classic Compatible – 3 hours 40 minutes – 8 hour Round Trip – 8 trains
  • Train 12 – Birmingham Curzon Street and Edinburgh or Glasgow – Classic Compatible – 3 hours 20 minutes – 7 hour Round Trip – 7 trains
  • Train 13 – Birmingham Curzon Street and Manchester – 200 metre Full-Size – 41 minutes – 2 hour Round Trip – 2 trains
  • Train 14 – Birmingham Curzon Street and Manchester – 200 metre Full-Size – 41 minutes – 2 hour Round Trip – 2 trains

Note.

  1. I have assumed 400 metre Full-Size trains will be a pair of 200 metre trains.
  2. Trains 4, 10 and 11 are pairs of 200 metre long Classic-Compatible trains, that  split and join at Crewe. Carlisle and Carlisle respectively.
  3. Trains 5 and 6 are single 200 metre long Classic-Compatible trains.
  4. The full schedule will need 34 Full-Size trains and 56 Classic-Compatible trains

According to Wikipedia, the first order will be for 54 Classic-Compatible trains, so I would assume, that more trains will be ordered.

Eastern Leg

These are the services for the Eastern Leg between London , Birmingham, East Midlands Hub, Leeds, Sheffield, York and Newcastle.

  • Train 15 – Birmingham Curzon Street and Leeds – 200 metre Full-Size – 49 minutes – 2 hour Round Trip – 2 trains
  • Train 16 – Birmingham Curzon Street and Leeds – 200 metre Full-Size – 49 minutes – 2 hour Round Trip – 2 trains
  • Train 17 – Birmingham Curzon Street and Newcastle – Classic Compatible – 1 hour 57 minutes – 5 hour Round Trip – 5 trains
  • Train 18 – London Euston and Sheffield – Classic Compatible – 1 hour 27 minutes – 4 hour Round Trip – 4 trains
  • Train 18 – London Euston and Leeds – Classic Compatible – 1 hour 21 minutes – 3 hour Round Trip – 3 trains
  • Train 19 – London Euston and Leeds – 400 metre Full-Size – 1 hour and 21 minutes – 3 hour Round Trip – 6 trains
  • Train 20 – London Euston and Leeds – 400 metre Full-Size – 1 hour and 21 minutes – 3 hour Round Trip – 6 trains
  • Train 21 – London Euston and Sheffield – Classic Compatible – 1 hour 27 minutes – 4 hour Round Trip – 4 trains
  • Train 21 – London Euston and York – Classic Compatible – 1 hour 24 minutes – 3 hour Round Trip – 3 trains
  • Train 22 – London Euston and Newcastle – Classic Compatible – 2 hour 17 minutes – 5 hour Round Trip – 5 trains
  • Train 23 – London Euston and Newcastle – Classic Compatible – 2 hour 17 minutes – 5 hour Round Trip – 5 trains

Note.

  1. I have assumed 400 metre Full-Size trains will be a pair of 200 metre trains.
  2. Trains 15 and 16 work as a pair,
  3. Trains 18 and 21 are pairs of 200 metre long Classic-Compatible trains, that split and join at East Midlands Hub.
  4. Trains 22 and 23 are single 200 metre long Classic-Compatible trains
  5. The full schedule will need 16 Full-Size trains and 29 Classic-Compatible trains.

Adding the two legs together and I estimate that 50 Full-Size trains and 85 Classic-Compatible trains, will be needed to run a full schedule.

Trains Per Hour On Each Section

It is possible to make a table of how many trains run on each section of the High Speed Two network in trains per hour (tph)

  • London Euston (stops) – 1-11, 18-23 – 17 tph
  • London Euston and Old Oak Common – 1-11, 18-23 – 17 tph
  • Old Oak Common (stops) – 1-11, 18-23 – 17 tph
  • Old Oak Common and Birmingham Interchange – 1-11, 18-23 – 17 tph
  • Birmingham Interchange (stops) – 2, 3, 7, 11, 20 – 5 tph
  • Birmingham Curzon Street (stops) – 1-3, 12-14, 15-17 – 9 tph
  • Birmingham and Crewe – 4,5, 7-9, 10-14 – 10 tph
  • Crewe (stops) – 4,5 – 2 tph
  • Crewe and Liverpool – 4,5 – 2 tph
  • Crewe and Lancaster – 4, 10-12 – 4 tph
  • Crewe and Manchester – 7-9, 13, 14 – 5 tph
  • Crewe and Wigan via Warrington – 4 – 1 tph
  • Crewe and Wigan via High Speed Two (new route) – 10-12 – 3 tph
  • Lancaster (stops) 4 – 1 tph
  • Lancaster and Carlisle  – 10-12 – 3 tph
  • Carlisle and Edinburgh – 10-12 – 2.5 tph
  • Carlisle and Glasgow – 10-12 – 2.5 tph
  • Birmingham and Stoke – 6 – 1 tph
  • Stoke (stops) – 6 – 1 tph
  • Stoke and Macclesfield – 6 – 1 tph
  • Macclesfield (stops) – 6 – 1 tph
  • Birmingham and East Midlands Hub – 15-17, 18-20, 21-23 – 9 tph
  • East Midlands Hub (stops) – 15-17, 18-20, 21 – 7 tph
  • East Midlands Hub and Sheffield – 18, 21 – 2 tph
  • Sheffield (stops) – 18, 21 – 2 tph
  • Midlands Hub and Leeds – 15, 16, 18-20 – 5 tph
  • Leeds (stops) – 15, 16, 18-20 – 5 tph
  • East Midlands Hub and York – 17, 21-23 – 4 tph
  • York (stops) – 17, 21-23 – 4 tph
  • York and Newcastle – 17, 22, 23 – 3 tph
  • Newcastle (stops) – 17, 22, 23 – 3 tph

These are a few thoughts.

Capacity Of The Southern Leg

The busiest section is between London Euston and Birmingham Interchange, which handles 17 tph.

As the maximum capacity of High Speed Two is laid down in the Phase One Act as 18 tph, this gives a path for recovery, according to the article.

Trains Serving Euston

The following train types serve London Euston station.

  • Full-Size – 8 tph
  • 400 metre Classic-Compatible – 5 tph
  • 200 metre Classic-Compatible – 4 tph

In the current service proposal, , Trains  5,6, 22 and 23 are just single 200 metre Classic Compatible trains.

This is inefficient and another four tph could be run into Euston station, by the use of appropriate splitting and joining.

  • Train 5 could run an identical manner to Train 4 to give extra services to Lancaster, Preston, Wigan North Western and Warrington Bank Quay.
  • Train 6 to Macclesfield is a problem and perhaps should call at Birmingham Interchange, where it could split and join to serve somewhere else like Wolverhampton and Shrewsbury.
  • Trains 22 and 23 could split and join at East Midlands Hub and serve other places in the East of England like Cleethorpes, Hull, Lincoln, Middlesbrough and Scarborough.

Paths are expensive entities to provide and every path into Euston should support a 400 metre train or a pair of 200 metre trains.

Platform Use At Euston

This page on the High Speed Two web site, gives details of Euston High Speed Two station.

HS2 will deliver eleven new 400m long platforms, a new concourse and improved connections to Euston and Euston Square Underground stations. Our design teams are also looking at the opportunity to create a new northerly entrance facing Camden Town as well as new east-west links across the whole station site.

So how will the eleven platforms be used?

Destinations served from London are planned to be as follows.

  • Birmingham Curzon Street – Full-Size – 3 tph
  • Edinburgh/Glasgow – Classic-Compatible – 2 tph
  • Lancaster – Classic-Compatible – 1 tph
  • Leeds – Full-Size – 2 tph – Classic-Compatible – 1 tph

Liverpool – Classic-Compatible – 2 tph

  • Macclesfield – Classic-Compatible – 1 tph
  • Manchester Piccadilly – Full-Size – 3 tph
  • Newcastle – Classic-Compatible – 2 tph
  • Sheffield – Classic-Compatible – 2 tph
  • York – Classic-Compatible – 1 tph

That is ten destinations and there will be eleven platforms.

I like it! Lack of resources is often the reason systems don’t work well and there are certainly enough platforms.

Could platforms be allocated something like this?

  • Birmingham Curzon Street – Full-Size
  • Edinburgh/Glasgow – Classic-Compatible
  • Leeds – Full-Size
  • Liverpool – Classic-Compatible – Also serves Lancaster
  • Macclesfield – Classic-Compatible
  • Manchester Piccadilly – Full-Size
  • Newcastle – Classic-Compatible
  • Sheffield – Classic-Compatible – Also serves Leeds and York

Note.

  1. No  platform handles more than three tph.
  2. There are three spare platforms.
  3. Each platform would only be normally used by one train type.
  4. Only Birmingham Interchange, East Midlands Hub, Leeds, Preston and York are not always served from the same platform.

Platform arrangements could be very passenger- and operator-friendly.

Platform Use At Birmingham Curzon Street

Birmingham Curzon Street station has been designed to have seven platforms.

Destinations served from Birmingham Curzon Street station are planned to be as follows.

  • Edinburgh/Glasgow – Classic-Compatible – 1 tph
  • Leeds – Full-Size – 2 tph
  • London Euston – Full-Size – 3 tph
  • Manchester Piccadilly – Full-Size – 2 tph
  • Newcastle – Classic-Compatible – 1 tph
  • Nottingham – Classic-Compatible – 1 tph

Note.

  1. The Nottingham service has been proposed by Midlands Engine Rail, but will be running High Speed Two Classic Compatible trains.
  2. That is six destinations and there will be seven platforms.

I like it! For the same reason as London Euston.

Could platforms be allocated something like this?

  • Edinburgh/Glasgow – Classic-Compatible
  • Leeds – Full-Size
  • London Euston – Full-Size
  • Manchester Piccadilly – Full-Size
  • Newcastle/Nottingham – Classic-Compatible

Note.

  1. No  platform handles more than three tph.
  2. There are two spare platforms.
  3. Each platform would only be normally used by one train type.
  4. Only East Midlands Hub is not always served from the same platform.

Platform arrangements could be very passenger- and operator-friendly.

Back-to-Back Services via Birmingham Curzon Street

The current plan for High Speed Two envisages the following services between the main terminals served by Full-Size trains.

  • London Euston and Birmingham Curzon Street – 3 tph – 45 minutes
  • London Euston and Leeds – 2 tph – 81 minutes
  • London Euston and Manchester Piccadilly – 3 tph – 71 minutes
  • Birmingham Curzon Street and Leeds – 2 tph – 40 minutes
  • Birmingham Curzon Street and Manchester Piccadilly – 2 tph – 41 minutes

Suppose a traveller wanted to go between East Midlands Hub and Manchester Airport stations.

Wouldn’t it be convenient if the Leeds to Birmingham Curzon Street train, stopped in Birmingham Curzon Street alongside the train to Manchester Airport and Piccadilly, so passengers could just walk across?

Or the two services could be run Back-to-Back with a reverse in Birmingham Curzon Street station?

Note.

  1. The current fastest times between Nottingham and Manchester Airport stations are around two-and-a-half hours, with two changes.
  2. With High Speed Two, it looks like the time could be under the hour, even allowing up to eight minutes for the change at Birmingham Curzon Street.

The design of the track and stations for High Speed Two, has some interesting features that will be exploited by the train operator, to provide better services.

Capacity Of The Western Leg Between Birmingham And Crewe

The section is between Birmingham and Crewe, will be running 10 tph.

As the maximum capacity of High Speed Two is laid down in the Phase One Act as 18 tph, this gives plenty of room for more trains.

But where will they come from?

High Speed One copes well with a few interlopers in the shape of Southeastern’s Class 395 trains, which run at 140 mph, between the Eurostars.

High Speed Two is faster, but what is to stop an operator running their own Classic-Compatible trains on the following routes.

  • Birmingham Curzon Street and Liverpool via Crewe, Runcorn and Liverpool South Parkway.
  • Birmingham Curzon Street and Holyhead via Crewe, Chester and an electrified North Wales Coast Line.
  • Birmingham Curzon Street and Blackpool via Crewe, Warrington Bank Quay, Wigan North Western and Preston.
  • Birmingham Curzon Street and Blackburn and Burnley via Crewe, Warrington Bank Quay, Wigan North Western and Preston.

Note.

  1. If these trains were say 130 metres long, they could call at all stations, without any platform lengthening.
  2. I’m sure that the clever engineers at Hitachi and Hyperdrive Innovation could come up with battery electric Classic-Compatible train, that could run at 225 mph on High Speed Two and had a battery range to reach Holyhead, with a small amount of electrification.
  3. A pair of trains, could work the last two services with a Split/Join at Preston.

The advantages of terminating these service in Birmingham Curzon Street would be as follows.

  • A lot more places get a fast connection to the High Speed Two network.
  • Passengers can reach London with an easy change at Birmingham Curzon Street station.
  • They can also walk easily between the three Birmingham stations.

But the big advantage is the trains don’t use valuable paths on High Speed Two between Birmingham Curzon Street and London Euston.

Crewe Station

In the current Avanti West Coast timetable, the following trains pass through Crewe.

  • London Euston and Blackpool – 4 trains per day (tpd)
  • London Euston and Chester – 1 tph
  • London Euston and Edinburgh/Glasgow – 2 tph
  • London Euston and Liverpool – 1 tph
  • London Euston and Manchester Piccadilly – 1 tph

Most trains stop at Crewe.

In the proposed High Speed Two timetable, the following trains will pass through Crewe.

  • London Euston and Edinburgh/Glasgow – 2 tph
  • London Euston and Lancaster/Liverpool – 2 tph
  • London Euston and Manchester – 3 tph
  • Birmingham Curzon Street and Edinburgh/Glasgow  -1 tph
  • Birmingham Curzon Street and Manchester – 2 tph

Note.

  1. Only the Lancaster and Liverpool trains stop at Crewe station.
  2. North of Crewe there will be a three-way split of High Speed Two routes to Liverpool, Wigan and the North and Manchester Airport and Piccadilly.
  3. High Speed Two will loop to the East and then join the West Coast Main Line to the South of Wigan.
  4. High Speed Two trains will use the West Coast Main Line to the North of Wigan North Western station.

This map of High Speed Two in North West England was captured from the interactive map on the High Speed Two web site.

 

 

Note.

  1. The current West Coast Main Line (WCML) and Phase 2a of High Speed Two are shown in blue.
  2. Phase 2b of High Speed Two is shown in orange.
  3. The main North-South route, which is shown in blue, is the WCML passing through Crewe, Warrington Bank Quay and Wigan North Western as it goes North.
  4. The Western Branch, which is shown in blue, is the Liverpool Branch of the WCML, which serves Runcorn and Liverpool.
  5. High Speed Two, which is shown in orange, takes a faster route between Crewe and Wigan North Western.
  6. The Eastern Branch, which is shown in orange, is the Manchester Branch of High Speed Two, which serves Manchester Airport and Manchester Piccadilly.
  7. The route in the East, which is shown in blue, is the Macclesfield Branch of High Speed Two, which serves Stafford, Stoke-on-Trent and Macclesfield.

The route of Northern Powerhouse Rail between Manchester Airport and Liverpool has still to be finalised.

Liverpool Branch

Consider.

  • The Liverpool Branch will take  two tph between London Euston and Liverpool.
  • In the future it could take up to 6 tph on Northern Powerhouse Rail between Liverpool and Manchester Piccadilly via Manchester Airport.

I believe that Liverpool Lime Street station, after the recent updating can handle all these trains.

Manchester Branch

This document on the Government web site is entitled HS2 Phase 2b Western Leg Design Refinement Consultation.

It indicates two important recently-made changes to the design of the Manchester Branch of High Speed Two.

  • Manchester Airport station will have four High Speed platforms instead of two.
  • Manchester Piccadilly station will have six High Speed platforms instead of four.

These changes will help the use of these stations by Northern Powerhouse Rail..

Consider.

  • The Manchester Branch will be new high speed track, which will probably be built in a tunnel serving Manchester Airport and Manchester Piccadilly stations.
  • The Manchester Branch will terminate in new platforms.
  • The Manchester Branch will take  five tph between Birmingham Curzon Street or London Euston and Manchester Airport and Manchester Piccadilly.
  • In the future it could take up to six tph on Northern Powerhouse Rail between Liverpool and Manchester Piccadilly via Manchester Airport.
  • London Euston and Old Oak Common will be new stations on a tunnelled approach to London and will handle 18 tph.

If London Euston and Old Oak Common can handle 18 tph, I can’t see why Manchester Airport and Piccadilly stations can’t handle somewhere near a similar number of trains.

At the moment eleven tph have been allocated to the Manchester Branch.

I believe that if infrastructure for Northern Powerhouse Rail was designed so that as well as connecting to Manchester and Liverpool, it connected Manchester and the West Coast Main Line running North to Preston, Carlisle and Scotland, services to the following destinations would be possible.

  • Barrow
  • Blackburn
  • Blackpool
  • Edinburgh
  • Glasgow
  • Windermere

Note.

  1. Edinburgh and Glasgow would probably be a service that would alternate the destination, as it is proposed for High Speed Two’s Birmingham and Scotland service.
  2. There would probably be a need for a North Wales and Manchester service via Chester.
  3. All trains would be Classic-Compatible.

If the Manchester Branch were to be built to handle 18 tph, there would be more than enough capacity.

Crewe, Wigan And Manchester

My summing up earlier gave the number of trains between Crewe, Wigan and Manchester as follows.

  • Crewe and Manchester – 5 tph
  • Crewe and Wigan via Warrington  – 1 tph
  • Crewe and Wigan via High Speed Two (new route) – 3 tph

This map of High Speed Two where the Manchester Branch leaves the new High Speed Two route between Crewe and Wigan was captured from the interactive map on the High Speed Two web site.

Note.

  1. The Manchester Branch runs to the South of the M56,
  2. The large blue dot indicates Manchester Airport station.
  3. Wigan is to the North.
  4. Crewe is to the South.
  5. Manchester Piccadilly is to the North East.

I believe this junction will be turned into a full triangular junction, to connect Wigan directly to Manchester Airport and Manchester Piccadilly.

  • Barrow, Blackburn, Blackpool, Preston and Windermere could all have high speed connections to Manchester Airport and Manchester Piccadilly. Trains could be shorter Classic-Compatible trains.
  • A Manchester and Scotland service would take the same route.

Another pair of tracks could leave the junction to the West to create a direct route between Manchester Airport and Liverpool for Northern Powerhouse Rail, by sneaking along the  M56.

Suppose extra services were as follows.

  • Manchester and Barrow – 1 tph
  • Manchester and Blackburn – 1 tph
  • Manchester and Blackpool – 1 tph
  • Manchester and Liverpool – 6 tph
  • Manchester and Scotland – 1 tph
  • Manchester and Windermere – 1 tph

The frequencies from the junction would be as follows.

  • To and from Crewe – High Speed Two (Manchester) – 5 tph – High Speed Two (North) – 3 tph = 8 tph
  • To and from Liverpool – Northern Powerhouse Rail – 6 tph = 6 tph
  • To and from Manchester – High Speed Two – 5 tph – Northern Powerhouse Rail – 6 tph – Local – 4 tph – Scotland – 1 tph = 16 tph
  • To and from Wigan – High Speed Two – 3 tph – Local – 4 tph – Scotland – 1 tph = 8 tph.

Only the Manchester Branch would be working hard.

The Liverpool Connection

I indicated that another pair of tracks would need to extend the Manchester Branch towards Liverpool in the West for Northern Powerhouse Rail.

  • Would these tracks have a station at Warrington?
  • Would there be a connection to allow services between Liverpool and the North and Scotland?

It might even be possible to design a Liverpool connection, that avoided using the current Liverpool Branch and increased the capacity and efficiency of all trains to Liverpool.

Capacity Of The Western Leg Between Wigan And Scotland

The sections between  Crewe and Carlisle, will be running at the following frequencies.

  • Wigan and Lancaster – 4 tph
  • Lancaster and Carlisle  – 3 tph
  • Carlisle and Edinburgh  – 2.5 tph
  • Carlisle and Glasgow – 2.5 tph

Note.

  1. The unusual Scottish frequencies are caused by splitting and joining at Carlisle and alternate services to Edinburgh and Glasgow.
  2. Any local high speed services and a Scotland service from Manchester, will increase the frequencies.

Over this section the services will be running on an improved West Coast Main Line.

But in some cases the trains will be replacing current services, so the increase in total frequencies will be less than it first appears.

Avanti West Coast currently run the following Scottish services.

  • One tph – London Euston and Glasgow via the most direct route.
  • One tph – London Euston and alternately Edinburgh and Glasgow via Birmingham.

This means that effectively Glasgow has 1.5 tph and Edinburgh 0.5 tph from London Euston.

The capacity of the current eleven-car Class 390 trains is 145 First and 444 Standard Class seats, which compares closely with the 500-600 seats given in Wikipedia for High Speed Two trains. So the capacity of the two trains is not that different.

But High Speed Two will be running 2.5 tph Between London Euston and both Edinburgh and Glasgow.

I would expect, that Class 390 services to Scotland will be discontinued and replaced by High Speed Two services.

Capacity Of The Eastern Leg Between Birmingham And East Midlands Hub

The section is between Birmingham and East Midlands Hub, will be running 9 tph

As the maximum capacity of High Speed Two is laid down in the Phase One Act as 18 tph, this gives plenty of room for more trains.

But where will they come from?

Midlands Engine Rail is proposing a service between Birmingham Curzon Street and Nottingham.

  • It will have a frequency of one tph.
  • It will be run by High Speed Two Classic-Compatible trains.
  • The journey will take 33 minutes.
  • It will run on High Speed Two infrastructure between Birmingham Curzon Street and East Midlands Hub.

If High Speed Two has been designed with this service in mind, I doubt it will be a difficult service to setup.

  • There might be enough capacity on High Speed Two  for two tph on the route,
  • It could possibly be extended to Lincoln.

It will also depend on the service timing being consistent with an efficient use of trains and platforms.

  • Thirty-three minutes is not a good timing, as it means twenty-seven minutes wait in a platform to get a round trip time, that suits clock-face time-tabling.
  • The current Lincoln and Nottingham service takes 56 minutes for 34 miles.
  • LNER’s London Kings Cross and Lincoln service travels the 16 miles between Lincoln and Newark in 25 minutes.
  • I estimate that after track improvements,  with a single stop at Newark Castle station, that Nottingham and Lincoln could be achieved in several minutes under fifty minutes.
  • This would enable a sub-ninety minute journey time between Birmingham Curzon Street and Lincoln, with enough time to properly turn the trains at both ends of the route.
  • The three hour round trip would mean that an hourly service would need three trains.

This is probably just one of several efficient time-tabling possibilities.

Are there any other similar services?

The obvious one is surely Cambridge and Birmingham

  • It would run via Peterborough, Grantham, Nottingham and East Midlands Hub.
  • It would connect the three big science, engineering and medical centres in the Midlands and the East.
  • It could be run by High Speed Two Classic-Compatible trains.

It might even be a replacement for CrossCountry’s Stansted Airport and Birmingham service.

Capacity Of The Eastern Leg Between East Midlands Hub And Sheffield

The section between East Midlands Hub and Sheffield, will be running 2 tph

As the maximum capacity of High Speed Two is laid down in the Phase One Act as 18 tph, this gives plenty of room for more trains.

But where will they come from?

This map of High Speed Two where the Sheffield Branch leaves the new High Speed Two route between East Midlands Hub and Leeds was captured from the interactive map on the High Speed Two web site.

Note.

  1. The main route of High Speed Two between East Midlands Hub, is shown in orange and follows the route of the M1 Motorway, towards the East of the map.
  2. The Sheffield Branch is new track to Clay Cross North Junction, where is takes over the Midland Main Line to Sheffield, which is shown in blue.
  3. The line going South in the middle of the map is the Erewash Valley Line, which goes through Langley Mill and Ilkeston stations.

I suspect Clay Cross to Sheffield will be an electrified high speed line, with a maximum speed of at least 140 mph.

Could the Erewash Valley Line have been used as an alternative route to Sheffield?

This map of High Speed Two captured from their interactive map, shows the connection of High Speed Two and the Erewash Valley Line to East Midlands Hub.

Note.

  1. East Midlands Hub is shown by the big blue dot.
  2. High Speed Two is shown in orange.
  3. The route to Leeds vaguely follows the M1 Motorway.
  4. The Erewash Valley Line goes North to the East of Ilkeston.

Would have been quicker and easier to electrify the Erewash Valley Line, as the High Speed Two route to Chesterfield and Sheffield?

  • Network Rail updated the route a few years ago.
  • It does not have the problems of electrification, through a World Heritage Site, as does the route through Derby.
  • It could surely handle two tph, even if they were High Speed Two Classic Compatible trains.
  • Sheffield will be just under ninety minutes from London by High Speed Two, as opposed to two hours now.

I suspect that it all comes down to saving a few minutes to Sheffield and the civic pride of having a High Speed Two connection.

So it looks like we’ll have the following capacity between East Midlands Hub and Sheffield.

  • Between East Midlands Hub and Clay Cross North Junction, there will be the High Speed Two capacity of 18 tph.
  • Between Clay Cross and Sheffield, there will probably be an upgraded capacity of perhaps 8-10 tph.

It seems a lot of capacity for just two tph.

Consider.

  • High Speed Two is planning to run three tph between Birmingham Curzon Street and East Midlands Hub
  • Midlands Rail Engine is planning to run one tph between Birmingham Curzon Street and East Midlands Hub
  • Four tph is considered a Turn-Up-And-Go service, and could exist between Birmingham Curzon Street and East Midlands Hub.
  • Sheffield and Leeds, both probably need a Turn-Up-And-Go service, to and from East Midlands Hub.
  • Semi-fast services between Sheffield and East Midlands Hub, calling at Chesterfield, Alfreton, Langley Mill and Ilkeston would be possible, by using the Erewash Valley Line.
  • The Maid Marian Line will join the Robin Hood Line in adding extra connectivity to East Midlands Hub Station.
  • Leeds and East Midlands Hub could have a six tph service courtesy of High Speed Two and Midlands Rail Engine.

Using High Speed Two’s web site, the following times should be possible.

  • Sheffield and East Midlands Hub – 27 minutes
  • Sheffield and Birmingham Curzon Street – 47 minutes.

Both services allow time for an efficient service.

There are certainly many options to create a Turn-Up-And-Go service between Sheffield and East Midlands Hub and also improve connections to other locations across the area.

Capacity Of The Eastern Leg Between East Midlands Hub And Leeds

The section is between East Midlands Hub and Leeds, will be running 5 tph

High Speed Two between Midlands Hub and Leeds is a totally new high speed line.

  • As the maximum capacity of High Speed Two is laid down in the Phase One Act as 18 tph, this gives plenty of room for more trains.
  • The Southern section of the leg closely follows the M1 Motorway.
  • Leeds, York and Newcastle will be 27, 36 and 93 minutes from East Midlands Hub, respectively.

This map of High Speed Two, which shows the route of the line in Yorkshire, was captured from the interactive map on the High Speed Two web site.

Note.

  1. Sheffield is marked by the blue dot in the South.
  2. Leeds is marked by the blue dot in the North West.
  3. York is marked by the blue dot in the North East.
  4. New routes are shown in orange.
  5. Upgraded routes are shown in blue.

The route seems to open up several possibilities for extra routes.

  • Leeds and Sheffield will be used by Northern Powerhouse Rail and there will be four tph, taking 28 minutes.
  • Leeds and Bedford via East Midlands Hub has been proposed by Midlands Rail Engine.
  • Services between Sheffield and the North via York must be a possibility.

This map of High Speed Two, which shows the routes to the East of Leeds, was captured from High Speed Two’s interactive map.

I think that two things might be missing.

  • A full triangular junction would surely allow services between Leeds and the North via York.
  • A high speed connection to Hull.

We shall see in the future.

Capacity Of The Eastern Leg Between York And Newcastle

The section between  York and Newcastle, will be running at a frequency of 3 tph.

Over this section the services will be running on an improved East Coast Main Line.

Conclusion

I shall split the conclusions into various sections.

Route And Track Layout

I think there may be places, where the route and track layout might need to be improved.

  • The Manchester Branch probably needs a triangular junction with the Western Leg of High Speed Two.
  • How Liverpool is served by Northern Powerhouse Rail needs to be decided.
  • The approach to Leeds probably needs a triangular junction with the Eastern Leg of High Speed Two.
  • It is not clear how services will reach Hull.

Hopefully, these issues will become clear in the next year or so.

Capacity

The sections with the highest levels of capacity would appear to be the following.

  • London Euston and Birmingham Interchange.
  • The Manchester Branch
  • The section shared with the East Coast Main Line between York and Newcastle.
  • The section shared with the West Coast Main Line between Wigan and Scotland.

But on these sections extra trains can be run.

  • Birmingham and North West England
  • Birmingham and East Midlands Hub
  • East Midlands Hub and Leeds
  • East Midlands Hub and Sheffield
  • East Midlands Hub and York

I can see, this capacity being filled by high speed local services, like those proposed by Midlands Rail Engine.

Rolling Stock

The only comment, I will make, is that there could be a need for a shorter Classic-Compatible train to work local services.

Testing Begins On Midland Main Line Electrification

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

  • From the article, it looks like the first part of mechanical testing has been completed as planned and unpowered pantograph runs have been performed at up to 110 mph.
  • It does seem to me, that this thirty  miles of electrification has avoided the troubles that have plagued similar projects in recent years.

Perhaps the good progress on this electrification, is making the government think again about early electrification of all of the  Midland Main Line

In Hopes Rekindled Of Full Midland Main Line Electrification. I showed how battery electric Class 810 trains would be able to work the route.

This was my conclusion of that earlier post.

It appears that both the Nottingham and Sheffield services can be run using battery electric Class 810 trains.

  • All four diesel engines in the Class 810 trains would need to be replaced with batteries.
  • The route between Clay Cross North Junction and Sheffield station, which will be shared with High Speed Two, will need to be electrified.
  • Charging facilities for the battery electric trains will need to be provided at Nottingham.

On the other hand using battery electric trains mean the two tricky sections of the Derwent Valley Mills and Leicester station and possibly others, won’t need to be electrified to enable electric trains to run on the East Midlands Railway network.

Will it be the first main line service in the world, run by battery electric trains?

There was one thing, that wasn’t available, a month ago, when I wrote that post – A charging system for battery electric trains, that could be installed at Nottingham.

In Vivarail’s Plans For Zero-Emission Trains, I report on Adrian Shooter’s plans for Vivarail, which are outlined in a video by Modern Railways.

Ar one point he says this   see about Vivarail’s Fast Charge system.

The system has now been given preliminary approval to be installed as the UK’s standard charging system for any make of train.

I may have got the word’s slightly wrong, but I believe the overall message is correct.

So could we see a Hitachi Class 810 train using Vivarail’s patented Fast Charge system at Nottingham?

In Interview: Hitachi’s Nick Hughes On Driving Innovation In Rail Propulsion, Nick Hughes of Hitachi is quoted as saying.

Rail is going to become increasingly digitised and integrated into other sectors involved in smart cities, mobility-as-a-service and flexible green grid. Therefore, Hitachi Rail won’t be able to stay at the forefront of innovation by its self. This is why we are focused on building partnerships with other like-minded, innovative, clean tech companies like Hyperdrive Innovation, Perpetuum and Hitachi group companies such as Hitachi ABB.

Does Vivarail fit that philosophy? In my view, it does!

This Hitachi infographic gives the specification of their Regional Battery Train.

Note.

  1. The range on battery power is 90 km or 56 miles at up to 100 mph.
  2. Class 810 trains could be converted to battery electric trains by replacing the diesel engines with batteries.
  3. As the electrification has reached Kettering. there is only 55 miles between London St Pancras and Nottingham without electrification.

I could see Class 810 trains running between St. Pancras and Nottingham on delivery, provided the following projects have been completed.

  • Hitachi have been able to give the Class 810 trains a range of say 60 miles on batteries.
  • Hitachi have modified their trains, so they can be recharged by a Vivarail Fast Charge system in fifteen minutes.
  • Vivarail have installed a Fast Charge facility at Nottingham station.

Network Rail are planning to extend the electrification from Kettering to Market Harborough, which would reduce the distance without electrification to under 50 miles. This would make running battery electric trains between London St. Pancras and Nottingham even easier.

Expanding The Network

If I am putting two and two together correctly and Hitachi have turned to Vivarail to provide a charging system or a licence for the use of the technology, I am sure, it would be possible to create a comprehensive network of battery electric trains.

Consider.

  • Hitachi should be able to squeeze a sixty mile range at 90-100 mph from a battery-equipped Class 810 trains.
  • Market Harborough and Derby are about 47 miles apart.
  • Derby and Sheffield are about 36 miles apart
  • Sheffield and Leeds are about 48 miles apart
  • Corby and Leicester are about 41 miles apart.

Vivarail Fast Charge systems at Derby, Leicester and Sheffield would enable the following routes to be run using battery electric trains.

  • London St. Pancras and Sheffield via Derby – Fast Charging at Derby and Sheffield
  • London St. Pancras and Leeds via Derby and Sheffield – Fast Charging at Derby and Sheffield
  • London St. Pancras and Sheffield via the Erewash Valley Line – Fast Charging at Ilkeston (?) and Sheffield
  • London St. Pancras and Leicester via Corby – Fast Charging at Leicester

Note.

  1. The only extra electrification needed for the initial network would be between Kettering and Market Harborough.
  2. The Class 810 trains would all be identical.
  3. The Class 810 trains might even be built and delivered as battery electric trains
  4. Trains would also charge the batteries between London St. Pancras and Market Harborough, between London St. Pancras and Corby. and between Leeds and Wakefield Westgate.

The network can be extended by adding more electrification and Fast Charge systems.

Conclusion

The technologies of Hitachi and Vivarail seem complimentary and could result in a fully electric main line train network for East Midlands Railway.

Interview: Hitachi’s Nick Hughes On Driving Innovation In Rail Propulsion

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

As with the article I discuss in Hydrogen On The Line, it is another well-written and informative article from The Engineer, where those at the sharp end of innovative rail technologies give their views.

This is the introductory paragraph.

As part of a series of articles exploring the propulsion technologies that will shape the future of key transport sectors The Engineer spoke to Hitachi Rail’s Nick Hughes about the innovations that will propel the rail sector into a low carbon future.

The Engineer asked these questions.

  1. What propulsion innovations will help power the rail sector towards net zero?
  2. Can you outline some of your organisation’s own key activities in this area?
  3. What are the key obstacles and challenges to developments in this area?
  4. What is your vision for the long-term future of propulsion in your sector?

I find the answer to the last question most interesting.

Rail is going to become increasingly digitised and integrated into other sectors involved in smart cities, mobility-as-a-service and flexible green grid. Therefore, Hitachi Rail won’t be able to stay at the forefront of innovation by its self. This is why we are focused on building partnerships with other like-minded, innovative, clean tech companies like Hyperdrive Innovation, Perpetuum and Hitachi group companies such as Hitachi ABB.

Hyperdrive Innovation is going to apply its knowledge and expertise from the automotive sector, to develop a market leading battery for Hitachi trains. Perpetuum predictive analytics improve reliability and availability of existing trains. Meanwhile, Hitachi ABB’s experience of the power sector allows our battery train solution to incorporate charging, storage and grid management. These partnerships creates an entry point into the rail market for our partners, potentially leading to future growth and jobs.

However, it is important to recognise that the established technologies of today – battery trains, discontinuous electrification and high-speed trains – are the technologies will help achieve the 2050 net zero emission target.

I would very much agree with all that is said.

Thoughts On The Design Of Hitachi’s Battery Electric Trains

If you look at a Class 800 or Class 802 train, they have underfloor diesel engines. Their powertrain is described like this in its own section in Wikipedia.

Despite being underfloor, the generator units (GU) have diesel engines of V12 formation. The Class 801 has one GU for a five to nine-car set. These provide emergency power for limited traction and auxiliaries if the power supply from the overhead line fails. The Class 800 and Class 802 bi-mode has three GU per five-car set and five GU per nine-car set. A five-car set has a GU situated under vehicles 2/3/4 and a nine-car set has a GU situated under vehicles 2/3/5/7/8.

There have been rumours of overheating.

Hitachi’s Regional Battery Train

Hitachi have teamed up with Hyperdrive Innovation to create a Regional Battery Train. There is this Press Release on the Hyperdrive Information web site, which is entitled Hitachi Rail And Hyperdrive Agreement P[ens Way For Battery Trains Across Britain.

This Hitachi infographic gives the specification.

Note, that this is a 100 mph train, with a range of 56 miles.

Typical routes would include a route like Norwich and Stansted Airport via Cambridge.

  • It is 93 miles.
  • There are thirty-nine miles of electrification at the Stansted Airport end.
  • Norwich station is fully-electrified.
  • There is just 53 miles between the Trowse swing-bridge and Ely station, that is not electrified.

Trains would charge the batteries at both ends of the route and use battery power, where no electrification exists.

There are many similar routes like this in the UK.

Hitachi have also produced this video.

My thoughts lead me to a few questions.

Are The Battery Modules Simulated Diesel Engines?

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.

Stadler have three very similar trains, that are destined for the UK.

All share the same PowerPack-in-the-Middle design, which is shown in this picture.

There are four slots in the PowerPack, with two on either side and they can all hold, either a diesel engine or a battery. Only, the Class 756 trains, are planned to have batteries at present, to make the trains tri-mode and capable of being powered by overhead electric, on-board batteries or a diesel generator.

If I was designing the battery modules to slot into the PowerPack, I and many other engineers would make the battery module deliver similar characteristics and plug compatibility to the diesel module.

The train’s control computer, would be simpler to program and debug and would use modules appropriately to drive the train according to the driver’s instructions.

This interchangeability would also give the operator lots of flexibility, in how they configured and used the trains.

So will Hyperdrive Innovation use an approach for Hitachi, where the battery module has similar characteristics and plug compatibility to the current diesel module?

I wouldn’t be surprised if they did, as it allows modules to be quickly swapped as operational needs change and the train’s computer sorts out the train’s formation and acts accordingly.

On An Hitachi Regional Battery Train Will All Diesel Engines Be Replaced With Battery Modules?

If the computer is well-programmed, it should handle any combination of diesel engines and battery modules.

Perhaps for various routes different combinations might apply.

  • For maximum battery range, all modules would be batteries.
  • For maximum power, all modules would be diesel engines.
  • To handle some out and back routes, there might be three battery modules and a diesel engine to charge the batteries before return.
  • Could perhaps one or two battery modules be fitted to avoid using the diesel engines in stations and in sensitive areas?

On some routes all diesel engines will be replaced with batteries on Battery Regional Trains, but on others there could be a mixture of both battery and diesel engines.

It should be noted that Stadler achieve the same flexibility with their PowerPack-in-the-Middle design.

Operators will like this flexibility.

What Is The Capacity Of A Battery Module?

In How Much Power Is Needed To Run A Train At 125 mph?, I calculated that an all-electric Class 801 train uses 3.42 kWh per vehicle mile.

I can do a simple estimate based on this figure.

When running on batteries the train will need less energy due to less air resistance, because it is going at 100 mph, rather than 125 mph.

  • If the energy use is proportional to the speed, then at 100 mph, the energy use will be 2.73 kWh per vehicle mile.
  • But if the energy use is proportional to the square of the speed, the energy use will be 2.19 kWh per vehicle mile.

I will compromise and use 2.5 kWh per vehicle mile.

Total energy needed to move a five-car train 56 miles would be 5 x 56 x 2.5 or 700 kWh, which could be three batteries of 233 kWh.

These are not outrageous sizes and the batteries could probably be of a comparable weight to the current diesel engines. So replacement wouldn’t affect the handling of the train.

In addition, the batteries would need to be large enough to hold all the regenerated by braking during a stop.

  • The weight of a Class 800 train is 243 tonnes.
  • It can carry 326 passengers, who probably weigh 80 Kg with baggage, bikes and buggies.
  • This gives a total train weight of 269 tonnes.
  • Using Omni’s Kinetic Energy Calculator, the kinetic energy at 100 mph is just 75 kWh.
  • For completeness, at 125 mph, the kinetic energy is 117 kWh and at 140 mph, the kinetic energy is 146 kWh.

All these figures are small compared to the battery size needed for traction.

Will East Coast Train’s Class 803 trains Use The Same Technology?

On East Coast Trains‘s Class 803 trains, batteries will be fitted to maintain onboard services, in case of a power failure.

Have these batteries been designed by Hyperdrive Innovation, with perhaps less capacity?

As East Coast Trains’s route between London Kings Cross and Edinburgh is fully electrified, the trains probably won’t need any auxiliary traction power.

But would increasing the battery size make this possible?

Where Do Avanti West Coast Class 807 Trains Fit In?

Avanti West Coast‘s Class 807 trains are also members of the same Hitachi A-Train family.

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

This is said about the ten all-electric AT-300 trains for Birmingham, Blackpool and Liverpool services, which have now been numbered as Class 807 trains.

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.

It may also have the wiring for a diesel engine or a battery module, should operational experience indicate one is needed.

Will All Cars Be Wired Ready For A Diesel Or Battery Module?

A five-car Class 802 train currently has a diesel engine in cars 2, 3 and 4.

The Hitachi infographic says that a Regional Battery Train has a range of 56 miles on batteries.

Let’s assume that this range applies to a Class 802 train, that has been fitted with three battery modules.

If we take Hull Trains as an example, their Class 802 trains do the following sections using their diesel engines

  • Temple Hirst Junction and Beverley – 44.34 miles or 87 miles round trip
  • Temple Hirst Junction and Hull – 36 miles or 72 miles round trip

These distances mean that with a 56 mile range, there needs to be some form of changing at Hull and/or Beverley.

But supposing all cars are wired to accept batteries or diesel engines. This could mean the following.

  • A train with three batteries and a range of 56 miles, could fit a standard diesel engine as a range extender, which could also be used to charge the batteries at Hull or Beverley.
  • A train with four batteries, could have a range of 75 miles, which with regenerative braking and precise energy-saving driving could be able to go between Temple Hirst Junction and Hull and back on battery power.
  • A train with four batteries and a diesel engine,, could have a range of 75 miles on battery power. The diesel energy could be used as a range extender or to charge the batteries at Hull and/or Beverley.
  • Could a train with five batteries, which could have a range of 90 miles, be able to reach Beverley and return to Temple Hirst Junction?

Note.

  1. I have assumed that battery range is proportional to the number of batteries.
  2. There must also be scope for running slower to cut the amount of energy used.

In addition, all Hull Trains schedules seem to spend fifteen minutes or more in Hull station. This would be enough time to recharge the batteries.

I’m fairly certain, that if all cars were wired  for batteries or diesel engines, it would give the operators a lot of flexibility.

Running With Batteries And A Range Extender Diesel Engine

The LEVC TX taxi is described as a plug-in hybrid range extender electric vehicle, where a small petrol engine, can also be used to generate electricity to power the vehicle.

Suppose a Class 802 train was fitted with two battery modules and a diesel engine. Could the diesel act as a range extender, in the same way as the petrol engine does on the LEVC TX?

The diesel engines fitted to a Class 802 train are 700 kW, so if I’m right about the train having total battery capacity of 700 kWh, one engine would take an hour to charge the batteries.

Returning to my Hull Trains example, drivers could probably ensure that the train didn’t get stranded by judicial use of the a single diesel engine to charge the batteries, whilst running in rural areas along the route.

As there would only be one diesel engine rather than three, the noise would be much lower.

I suspect too, that a simple charger in Hull station could charge a train, as it passes through, to make sure it doesn’t get stranded in the countryside.

I suspect that a mix of batteries and diesel engines could be part of an elegant solution on some routes.

  • Edinburgh and Aberdeen
  • Edinburgh and Inverness
  • London Kings Cross and Hull
  • London Paddington and Swansea
  • London St. Pancras and Sheffield.
  • London St. Pancras and Nottingham

It might also be a useful configuration on some TransPennine routes.

Charging Battery Trains

Having a charger in a terminal station would open up a lot of routes to Hitachi’s battery electric trains.

At stations like Hull and Scarborough, this charger could be as simple as perhaps forty metres of 25 KVAC overhead electrification.

  • The train would stop in the station at the appropriate place.
  • The driver would raise the pantograph.
  • Charging would start.
  • When the battery is fully-charged, the driver would lower the pantograph.

This procedure could be easily automated and the overhead wire could be made electrically dead, if no train is connected.

It should be noted that Hitachi have recently acquired ABB’s power grid business, as announced in this Hitachi press release which is entitled Hitachi Completes Acquisition of ABB’s Power Grids Business; Hitachi ABB Power Grids Begins Operation.

Rail is not mentioned, but mobility is. So will this move by Hitachi, strengthen their offering to customers, by also providing the systems in stations and sidings to charge the trains.

This Google Map shows Hull station, with its large roof.

Could an integrated solution involving solar panels over the station be used to power electrification to charge the trains and dome electric buses next door?

Integrated solutions powered by renewable energy would appeal to a lot of municipalities seeking to improve their carbon profile.

Conclusion

These trains will transform a lot of rail services in the UK and abroad.
