Northern Powerhouse Rail – Significant Upgrades Of The East Coast Main Line From Leeds To Newcastle (Via York And Darlington) And Restoration Of The Leamside Line

In this article on Transport for the North, which is entitled Northern Powerhouse Rail Progress As Recommendations Made To Government, one of the recommendations proposed for Northern Powerhouse Rail is significant upgrades to the East Coast Main Line and reopening of the Leamside Line.

Northern Powerhouse Rail’s Objective For The Leeds and Newcastle Route

Wikipedia, other sources and my calculations say this about the trains between Leeds and Newcastle.

  • The distance between the two stations is 106 miles
  • The current service takes around 85 minutes and has a frequency of three trains per hour (tph)
  • This gives an average speed of 75 mph for the fastest journey.
  • The proposed service with Northern Powerhouse Rail will take 58 minutes and have a frequency of four tph.
  • This gives an average speed of 110 mph for the journey.

This last figure of 110 mph, indicates to me that a faster route will be needed.

These are example average speeds on the East Coast Main Line.

  • London Kings Cross and Doncaster – 156 miles – 98 minutes – 95.5 mph
  • London Kings Cross and Leeds – 186 miles – 133 minutes – 84 mph
  • London Kings Cross and York  – 188.5 miles – 140 minutes – 81 mph
  • London Kings Cross and Hull – 205.3 miles – 176 minutes – 70 mph
  • York and Newcastle – 80 miles – 66 minutes – 73 mph

I also predicted in Thoughts On Digital Signalling On The East Coast Main Line, that with full digital in-cab ERTMS signalling and other improvements, that both London Kings Cross and Leeds and York would be two-hour services, with Hull a two-and-a-half service.

  • London Kings Cross and Leeds in two hours would be an average speed of 93 mph.
  • London Kings Cross and York in two hours would be an average speed of 94.2 mph.
  • London Kings Cross and Hull in two-and-a-half hours would be an average speed of 94.2 mph.

I am fairly certain, that to achieve the required 110 mph average between Leeds and Newcastle to meet Northern Powerhouse Rail’s objective of four tph in under an hour will need, at least the following.

  • Full digital in-cab ERTMS signalling
  • Completion of the electrification between Leeds and York.
  • Ability to run at up to 140 mph in places.
  • Significant track upgrades.

It could also eliminate diesel traction on passenger services on the route.

High Speed Two’s Objective For The York and Newcastle Route

At the present time, High Speed Two is not planning to run any direct trains between Leeds and Newcastle, so I’ll look at its proposed service between York and Newcastle instead.

  • Current Service – 80 miles – 66 minutes – 73 mph
  • High Speed Two – 80 miles – 52 minutes – 92 mph

Note.

  1. High Speed Two will be running three tph between York and Newcastle.
  2. Northern Powerhouse Rail have an objective of 58 minutes for Leeds and Newcastle.

High Speed Two and Northern Powerhouse Rail do not not have incompatible ambitions.

Current Direct Leeds And Newcastle Services

These are the current direct Leeds and Newcastle services.

  • TransPennine Express – 1 tph – Liverpool Lime Street and Edinburgh
  • TransPennine Express – 1 tph – Manchester Airport and Newcastle.
  • CrossCountry – 1 tph – Plymouth and Edinburgh

Timings appear to be between 81 and 91 minutes.

What Would A Leeds And Newcastle In Under An Hour Do For London Kings Cross And Edinburgh Timings?

This question has to be asked, as a 58 minute time between Leeds and Newcastle will mean that timings between York and Newcastle must reduce.

York And Newcastle at various average speeds give the following times.

  • 73 mph (current average) – 66 minutes
  • 80 mph – 60 minutes
  • 90 mph – 53 minutes
  • 92 mph – 52 minutes (High Speed Two promise)
  • 100 mph – 48 minutes
  • 110 mph – 44 minutes

If any speed over 90 mph can be averaged between York and Newcastle, this means that with a London and York time of under two hours the following times are possible.

  • London Kings Cross and Newcastle in under three hours. – High Speed Two are promising two hours and seventeen minutes.
  • London Kings Cross and Edinburgh in under four hours. – High Speed Two are promising three hours and forty minutes.

Consider.

  • An InterCity 225 achieved a time of under three-and-a-half hours between London and Edinburgh. in 1991.
  • That record journey was at an average speed of 112 mph.
  • There must be opportunities for speed improvements North of Newcastle.
  • Train and signalling technology is improving.
  • High Speed Two is promising three hours and forty minutes between London and Edinburgh.

I can see a fascinating rivalry between trains on High Speed Two and the East Coast Main Line, developing, about who can be faster between London and Edinburgh.

Current Projects Between Leeds And Newcastle

These projects are in planning or under way on the section of the East Coast Main Line between Leeds and Newcastle.

Phase 2 Of The East Coast Main Line Power Supply Upgrade

Phase 1 between London and Doncaster should have been completed, if the covids allowed and now work can be concentrated on Phase 2 to the North of Doncaster.

This page on the Network Rail web site describes the project. These paragraphs are the introduction to Phase 2.

Phase 2 of the project will involve the installation of feeder and substations along the route, capacity upgrades, new 132kv connection at Hambleton junction and upgrades to existing power supply connections.

The second phase of the project is currently in design stages and dates for carrying out the work are still being finalised.

Phase 2 will be delivering upgraded power to the East Coast Mainline railway between Bawtry and Edinburgh.

This project may not improve speeds on the railway, but it will certainly improve reliability and reduce the use of diesel power.

I do wonder, that as the reliability of the East Coast Main Line increases, this will reduce the need for the electric Class 801 trains, to have diesel engines for when the power supply fails.

It is known, that the Class 803 trains, that are under construction for East Coast Trains, will have only a small battery for emergency use.

A sensible weight saving would surely improve the acceleration and deceleration of the trains.

York to Church Fenton Improvement Scheme

This page of the Network Rail web site, describes the project. These paragraphs introduce the project.

Our work between York and Church Fenton is in preparation for the Transpennine Upgrade, which will provide more capacity and faster journeys between Manchester Victoria and York, via Leeds and Huddersfield.

The five mile stretch between Church Fenton and Colton Junction – the major junction where trains from Leeds join the East Coast Main Line towards York – sees over 100 trains each day, with up to one freight or passenger train passing through every five minutes. This is one of the busiest stretches of railway in the North.

The work will include.

  • Modernising the signalling.
  • Replacing about five miles of track between Holgate (York) and Colton Junction.
  • Completing the eleven miles of electrification between York and Church Fenton stations.

I estimate that when the project is completed, there will be only around thirteen miles of track without electrification between Church Fenton station and Neville Hill TMD in Leeds.

The route between Church Fenton and Garforth stations, is shown in this map clipped from High Speed Two.

Note.

  1. York is just off the North-East corner of the map.
  2. Garforth is in the South-West corner of the map.
  3. Shown in orange is the new route of High Speed Two from East of Leeds towards York.
  4. Shown in blue is existing tracks, that will be used to take High Speed Two Trains to York and further North.
  5. The rail line running North-South on the edge of the map is the Selby Diversion, which opened in 1983 and  was built to avoid possible subsidence from the Selby coalfield.
  6. The pre-Selby Diversion route of the East Coast Main Line goes South from the join of the blue and orange sections of High Speed Two.
  7. At Church Fenton station, this route splits, with one route going West through Micklefield, East Garforth and Garforth stations to Neville Hill TMD and Leeds.
  8. The main road going North-South is the A1 (M).

It seems to me, that High Speed Two’s and Northern Powerhouse Rail’s plans in this area, are still being developed.

  • There has been no decision on the electrification between Church Fenton and Neville Hill TMD.
  • How do Northern Powerhouse Rail trains go between Leeds and Hull?
  • How do Northern Powerhouse Rail trains go between Leeds and York?
  • How do High Speed Two trains go between Leeds and York?

I suspect, when the full plans are published, it will answer a lot of questions.

Darlington Station Remodelling

A remodelling of Darlington station is under consideration.

I outlined this in £100m Station Revamp Could Double Local Train Services.

This was my conclusion in the related article.

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.

It will create a major interchange, where high speed trains from High Speed Two, LNER and Northern Powerhouse Rail will do the following.

  • Approach at 140 mph or more.
  • Perform a controlled stop in the station.
  • Drop and pick-up passengers.
  • Accelerate back up to linespeed.

The station stop will be highly-automated and monitored by the driver.

One of the objectives would be to save time for all fast trains.

Capacity And Other Problems Between Leeds And Newcastle Listed In Wikipedia

These problems are listed in a section called Capacity Problems in the Wikipedia entry for the East Coast Main Line.

The North Throat Of York Station Including Skelton Bridge Junction

On the thirty mile stretch of the East Coast Main Line, between York and Northallerton stations, the route is mainly four tracks.

But three miles North of York there is Skelton Bridge over the River Ouse, which is shown in this Google Map.

Zooming closer, I clipped this second Google Map.

Note.

  1. There are actually two bridges over the River Ouse.
  2. The East bridge is a double-track bridge and is the original stone arch bridge.
  3. The West bridge was added later and I suspect has little architectural merit.
  4. The tracks on both sides of the bridge are extremely complicated.

If you look at the timings, trains seem to take one of two timings between York and Northallerton.

  • 17-18 minutes, which is almost an average speed of 100 mph.
  • 27 minutes, which is 67 mph.

Incidentally, one of Drax’s long biomass trains managed a time of 27 minutes.

Would going faster save any minutes?

  • A 110 mph average would give a time of 16.4 minutes
  • A 120 mph average would give a time of 15 minutes
  • A 125 mph average would give a time of 14.4 minutes
  • A 140 mph average would give a time of 12.9 minutes

On the face of it, it doesn’t appear that there are very large time savings, to be achieved.

On the other hand, if all trains can pass through Skelton Bridge and its complicated junction, without slowing, delays will be minimised and timetables can be faster.

But there is an anomaly in all the express trains that pass through York station. All stop, except those planned for East Coast Trains. In fact, their trains won’t stop between Stevenage and Newcastle.

The obvious solution to the Skelton Bridge problem, is to do what British Rail didn’t have the courage to do, when they electrified the East Coast Main Line in the 1980s. And that is to demolish the bridge and build a stylish modern four-track bridge!

It would eliminate many of the things, that could go wrong and would surely improve reliability. This could help to maintain a higher operating speed.

But would it be allowed by the Planning Authorities and English Heritage?

Hopefully, it doesn’t matter!

  • I am a Control Engineer and mathematical modeller, who has programmed some immensely complex systems in the last fifty-five years.
  • I have also flown light aircraft on instruments for many hours, where you control the plane according to what Air Traffic Controllers and the instruments tell you.

My experience tells me that, it would be possible to control a busy junction, like Skelton Bridge safely, by a well-programmed computer system helping the driver, arrive at the junction at the right time to go straight through.

I also believe that if modern in-cab digital ERTMS signalling can handle twenty-four tph on Thameslink going to and from scores of stations, then it can handle Skelton Bridge Junction.

In Could ERTMS And ETCS Solve The Newark Crossing Problem?, I proposed a similar solution to the problem at Newark.

Use Of The Leamside Line

Wikipedia says this about capacity to the South of Newcastle.

South of Newcastle to Northallerton (which is also predominately double track), leading to proposals to reopen the Leamside line to passenger and freight traffic.

I could have included it in the previous section, but as it such a important topic, it probably deserves its own section.

Looking at maps, reopening is more than a a possibility. Especially, as reopening is proposed by Northern Powerhouse Rail and mentioned in the title of this post.

I discussed the Leamside Line in detail in Boris Johnson Backs Station Opening Which Could See Metro Link To County Durham, which I wrote in June this year.

These are some extra thoughts, that update the original post.

Ferryhill Station

I was prompted to write the related post, by something Boris Johnson said at PMQs and it was mainly about Ferryhill station.

In the latest copy of this document on the Government web site, which is entitled Restoring Your Railway: Successful Bids, a new station at Ferryhill has been successful. Another bid in the same area to restore rail services between Consett and Newcastle has also been successful.

This map shows the East Coast Main Line as it goes North South between Durham and Darlington.

Note.

  1. Ferryhill is in the South-West of the map opposite the sand-pits in the South-East
  2. The East Coast Main Line runs North-South between the village an d the sand-pits.
  3. Follow the railway North and you come to Tursdale, where there is a junction between the East Coast Main Line and the Leamside Line.
  4. The East Coast Main Line goes North-Westerly towards Durham and Newcastle.
  5. The Leamside Line goes North to Washington and Newcastle.
  6. There is also the Stillington Freight Line going South-Easterly to Sedgefield and Stockton from Ferryhill.

Could Ferryhill be a useful interchange to local services connecting to Newcastle, Sunderland and Washington in the North and Hartlepool, Middlesbrough and Stockton in the South?

The Leamside Line As An East Coast Main Line Diversion

I didn’t discuss using the line as a diversion for the East Coast Main Line in my original post, but if the infrastructure is to the required standard, I don’t see why it can’t take diverted traffic, even if it is also used for the Tyne and Wear Metro.

It should be remembered, that to create extra capacity on the East Coast Main Line between Peterborough and Doncaster, the route of the Great Northern and Great Eastern Joint Railway, was upgraded. I first wrote about this line six years ago in Project Managers Having Fun In The East and the route seems to be working well. It is now being augmented by the addition of the £200 million Werrington Dive Under. See Werrington Dive-Under – 8th November 2018, for more details of this project, which will speed up all trains on the East Coast Main Line.

After the undoubted success of the upgrade  of the Great Northern and Great Eastern Joint Railway, surely the team responsible for it, should be given the task of devising a similar plan for the Leamside Line, to take pressure off the East Coast Main Line between Newcastle and Northallerton.

Sharing The Leamside Line

The Tyne and Wear Metro also has its eyes on the Leamside Line for an extension.

It should be noted that the Extension To Wearside, uses the Karlsruhe Model to allow the Metro trains to share with freight and other passenger trains.

The new Stadler trains will probably make this even easier, so I wouldn’t be surprised to see a reopened Leamside Line handling a varied assortment of trains of all types.

The Sunderland Example

Sunderland station is a station, which has both Metro and mainline services from the same platforms.

Could a station at Washington be built to similar principles, so that some long distance services to Newcastle used this station?

A Terminal Station On The Leamside Line

Newcastle station may be a Grade One Listed station, but it is built on a curve and would be a nightmare to expand with more platforms.

Sunderland station is already used as a terminal for London trains, so would it be sensible to provide a terminal at somewhere like Washington?

My Final Thought  On The Leamside Line

Reopen it!

A Few Random Final Thoughts

This post has got me thinking.

Newcastle Station Capacity

I have seen reports over the years that Newcastle station, is lacking in capacity.

  • There could be extra services, as High Speed Two is proposing two tph from London Euston stations and one tph from Birmingham Curzon Street station.
  • There may be extra services because of Northern Powerhouse Rail, which has an objective of four tph from Leeds station.
  • There may be extra services because of new services to Ashington and Blyth.
  • There may be extra services because of new services to Consett.

Note.

  1. The first two services could use two hundred metre long trains.
  2. Some platforms can accept 234 metre long Class 800 trains.
  3. The last two services might use the Metro platforms.

As the station has twelve platforms, I feel with careful operation, that the station will have enough capacity.

This Google Map shows the station.

And this second Google Map shows the station, its position with relation to the Tyne and the lines rail routes to and from the station.

Note.

  1. Trains from the South arrive over the King Edward VII Bridge and enter Newcastle station from the West.
  2. Trains from England to Scotland go through the station from West to East and then go straight on and turn North for Berwick and Scotland.
  3. Next to the King Edward VII Bridge is the blue-coloured Queen Elizabeth II Bridge, which takes the Tyne and Wear Metro across the Tyne, where it uses two platforms underneath Newcastle station.
  4. The next bridge is the High Level Bridge, which connects the East end of the station to the rail network, South of the Tyne. It connects to the Durham Coast Line to Teeside and the Leamside Line.

History has delivered Newcastle a comprehensive track layout through and around Newcastle station.

  • Services from the East can be run back-to-back with services from the West.
  • The Metro and its two underground platforms removes a lot of traffic from the main station.
  • There are seven through platforms, of which at least three are over two hundred metres long.
  • There are four West-facing bay platforms and one facing East.

But most intriguingly, it looks like it will be possible for trains to loop through the station from the South, by perhaps arriving over the King Edward VII bridge and leaving over the High Level bridge. Or they could go the other way.

Could this be why reoopening the Leamside Line is important?

LNER’s Extra Paths

The sentence, from an article entitled LNER Seeks 10 More Bi-Modes, in the December 2020 Edition of Modern Railways   indicates that more capacity will be available to LNER.

Infrastructure upgrades are due to prompt a timetable recast in May 2022 (delayed from December 2021) from which point LNER will operate 6.5 trains per hour, out of Kings Cross, compared to five today.

I suspect that LNER could use the half path to run a one train per two hour (tp2h) service to Hull.

  • Currently, London Kings Cross and Hull takes a few minutes under three hours.
  • Currently, Doncaster and Hull takes around 55 minutes.
  • I have estimated that once full digital in-cab signalling is operational, that London Kings Cross and Hull could take a few minutes under two-and-a-half hours.

The full path to Hull could be shared with Hull Trains to provide an hourly service between London Kings Cross and Hull.

LNER could do something special with the full extra path.

Consider.

  • Some train operating companies have said, that they’ll be looking to attract customers from the budget airlines.
  • There could be a need for more capacity between London Kings Cross and all of Edinburgh, Leeds and Newcastle.
  • Faster services would be attractive to passengers.
  • York and Leeds will be fully electrified or trains could be fitted with batteries to bridge the thirteen mile gap in the electrification.

A limited-stop service between London Kings Cross and Edinburgh via Leeds could be an interesting addition.

  • The train would only stop at Leeds and possibly Newcastle.
  • One objective would be a time under three-and-a-half hours between London Kings Cross and Edinburgh.
  • What time could be achieved between London Kings Cross and Leeds?

It would certainly give High Speed Two a run for its money!

A New Elizabethan

In LNER Seeks 10 More Bi-Modes, I said this under a heading of A New Elizabethan.

I can remember The Elizabethan, which was a steam-hauled non-stop express between London and Edinburgh between 1953 and 1961.

    • The steam-hauled train took six-hours-and-a-half.
    • It used to be the longest non-stop railway service in the world.
    • Today, the service could be run by the current or refurbished Azumas or perhaps a new flagship train, built for the service.
    • It could be easily under four hours.

It could be an interesting concept, to increase capacity between London and Edinburgh.

As I indicated in the previous section, LNER certainly have a path, that could be used to their advantage.

High Speed Two

The East Coast Main Line and High Speed Two have a lot in common.

  • The two routes will share tracks between a junction near Ulleskelf station and Newcastle station.
  • High Speed Two Classic Compatible trains could be based on Hitachi AT-300 train technology.
  • High Speed Two Classic Compatible trains would probably be able to run on the East Coast Main Line between London Kings Cross And Edinburgh.
  • Trains from both routes will share platforms at York, Darlington, Durham and Newcastle stations.
  • I would hope that the signalling systems on both routes are compatible.

From a project management point of view, this commonality means that in an ideal world the new route of both High Speed Two and Northern Powerhouse Rail, and the upgrades to the East Coast Main Line should be planned together.

I believe there are still details on the design of the joint route, that have not been disclosed, or perhaps not even decided.

  • Will between Church Fenton station and Neville Hill depot be electrified?
  • How will Northern Powerhouse Rail connect Leeds and Hull stations?
  • How will Northern Powerhouse Rail connect Leeds and York stations?
  • Will High Speed Two connect Leeds and York stations?
  • What will be the operating speed of the joint section of the East Coast Main Line?
  • What will be the capacity in trains per hour of the joint section of the East Coast Main Line?
  • Will Newcastle station need an extra platform to handle three High Speed Two tph from London Euston

Two projects have been discussed in this post.

  • The unlocking of the bottleneck at Skelton Bridge.
  • The reopening of the Leamside Line.

I feel that these projects are important and will probably be needed for efficient operation of High Speed Two.

Other early projects could include.

  • Upgrading and electrification of the chosen route between Leeds and Hull,
  • Installation of the chosen system of in-cab ERTMS digital signalling on the route.
  • Electrification between Church Fenton station and Neville Hill depot.

I would deliver these and other joint projects early, so that travellers see a positive benefit from High Speed Two before the main work has even started.

High Speed East Coast

I wonder what is the maximum speed of the Class 80x trains, that are the backbone of services on the East Coast Main Line.

Consider.

  • It is known, that with in-cab digital ERTMS  signalling, these trains will be capable of 140 mph, but could they go even faster.
  • High Speed Two Classic Compatible trains will be capable of 225 mph.
  • Will Hitachi’s offering for these trains, be based on the Class 80x trains?

I would think, that it is fairly likely, that the existing Class 80x trains could be updated to an operating speed in the range of 150-160 mph.

In Thoughts On Digital Signalling On The East Coast Main Line, I said this.

The combined affect of both track and signalling improvements is illustrated by this simple calculation.

    • As Dalton-on-Tees is North of Doncaster, the route between Woolmer Green and Doncaster should be possible to be run at 140 mph
    • Woolmer Green and Doncaster stations are 132.1 miles apart.
    • Non-stop York and London Kings Cross trains are currently timed at 70 minutes between Doncaster and Woolmer Green stations.
    • This is an average speed of 113.2 mph.

If 140 mph could be maintained between Doncaster and Woolmer Green, the section of the journey would take 56.6 minutes, which is a saving of 13.4 minutes.

I can do this calculation for higher speeds.

  • 150 mph would take 52.8 minutes
  • 160 mph would take 49.5 minutes
  • 170 mph would take 46.6 minutes
  • 180 mph would take 44 minutes
  • 200 mph would take 39.6 minutes

Note.

  1. Eurostar’s latest Class 374 trains are capable of operating at 200 mph.
  2. A Class 395 train, which is closely related to the Class 80x trains, has attained a record speed of 157 mph.

There may be worthwhile time savings to be made, on some of the straighter sections of the East Coast Main Line.

Other improvements will also be needed.

Note, that I am assuming, that the Digswell Viaduct section would not be updated, as it would cause too much disruption.

I also believe that by using selective joining and splitting at Edinburgh, Leeds and perhaps Doncaster, Grantham, Newark or York, that a very comprehensive network of direct trains to and from London can be built from Grantham Northwards.

Beverley, Bradford, Cleethorpes, Glasgow, Grimsby, Harrogate, Huddersfield, Hull, Lincoln, Middlesbrough, Nottingham, Perth, Redcar, Sheffield, Skipton, Sunderland and Washington could all be served at an appropriate frequency.

  • Some like Bradford, Glasgow, Harrogate, Hull, Lincoln and Middlesbrough would have several trains per day.
  • Others might have a much more limited service.

What sort of timings will be possible.

  • London Kings Cross and Doncaster could be around an hour.
  • London Kings Cross and Leeds could be around one hour and thirty minutes, using the current Doncaster and Leeds time, as against the one hour and twenty-one minutes for High Speed Two.
  • London Kings Cross and York could be around one hour and twenty-three minutes, using the current Doncaster and York time, as against the one hour and twenty-four minutes for High Speed Two.
  • Timings between York and Newcastle would be the same fifty-two minutes as High Speed Two, as the track will be the limitation for both services.
  • High Speed Two’s timing for York and Newcastle is given as fifty-two minutes, with York and Darlington as twenty-five minutes.
  • London Kings Cross and Darlington could be around one hour and forty-nine minutes
  • London Kings Cross and Newcastle could be around two hours and sixteen minutes.
  • London Kings Cross and Edinburgh would be under three-and-a-half hours, as against the proposed three hours and forty-eight minutes for High Speed Two.

High Speed East Coast would be a serious and viable alternative to High Speed Two for the Eastern side of England and Scotland.

Conclusion

This is an important joint project for Northern Powerhouse Rail, High Speed Two and the East Coast Main Line.

 

Project Management Recommendations

This project divides neatly into several smaller projects..

  • Upgrade the power supply on the East Coast Main Line.
  • Finish the York to Church Fenton Improvement Scheme
  • Remodel Darlington station.
  • Install of in-cab ERTMS digital signalling.
  • Complete the electrification between Neville Hill TMD and York.
  • Solve the problem of Skelton Bridge and its complicated track layout.
  • Reopen the Leamside Line.

Most of these projects are independent of each other and all would give early benefits to the East Coast Main Line.

When complete, we’ll see the following timing improvements.

  • Leeds and Newcastle will drop from 85 minutes to 56 minutes, with an increase in frequency from three to four tph.
  • York and Newcastle will drop from 57-66 minutes to 52 minutes.
  • There could be ten minutes savings on Edinburgh services.

Passengers and operators would welcome this group of projects being started early.

!40 mph Electric Trains At Kings Cross Station

This picture shows LNER’s old and new 140 mph electric trains at Kings Cross station.

On the left is a nine-car Class 801 train.

  • Introduced into service in 2019
  • 234 metres long
  • Capacity – 510 Standard and 101 First
  • One diesel engine for emergency power.

On the right is an InterCity 225.

Both trains are designed for 140 mph and will be able to attain this speed, when in-cab digital signalling is available.

It looks like LNER will have the following full-size electric fleet.

  • Thirty Class 801 trains
  • Seven InterCity 225 trains and spare coaches, driving van trailers and locomotives.

Both trains will be able to work any route with full electrification.

Changes In The Future To LNER Services

I predict that the following will happen.

140 mph Running Between Woolmer Green And Doncaster

This will happen and the following trains will take advantage.

The odd ones out will be Grand Central’s Class 180 trains, which are diesel and only capable of 125 mph.

How long will the other train operating companies accept slow trains on the 140 mph railway?

Digital In-Cab Signalling And 140 mph Running Will Speed Up Services

In Thoughts On Digital Signalling On The East Coast Main Line, I said that following train times would be possible., in addition to a London Kings Cross and Leeds time of two hours.

  • London Kings Cross and Bradford Forster Square – two hours and thirty minutes
  • London Kings Cross and Harrogate – two hours and thirty minutes
  • London Kings Cross and Huddersfield – two hours and twenty minutes
  • London Kings Cross and Hull – two hours and thirty minutes
  • London Kings Cross and Middlesbrough – two hours and thirty minutes
  • London Kings Cross and Scarborough – two hours and thirty minutes
  • London Kings Cross and Skipton – two hours and thirty minutes
  • London Kings Cross and York – two hours

Note.

  1. All timings would be possible with Hitachi Class 80x trains.
  2. Timings on Fully-electrified routes would be possible with InterCity 225 trains.

It appears that Grand Central will be stuck in the slow lane.

Grand Central Will Acquire Hitachi Trains Or Give Up

Grand Central‘s destinations of Bradford Interchange and Sunderland can’t be reached by all-electric trains, so will either have to follow Hull Trains and purchase Hitachi bi-mode trains or give up their routes.

The Diesel Engines In The Class 801 Trains Will Be Replaced By Batteries

East Coast Trains’ Class 803 trains have a slightly different powertrain to LNER’s Class 801 trains, which is explained like this in Wikipedia.

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.

I wouldn’t be surprised to see a similar battery system fitted to the Class 801 trains.

The Diesel Engines In Hull Trains Class 802 Trains Will Be Replaced By Batteries

In Hull Issues New Plea For Electrification, I showed how Hitachi’s Class 802 trains with batteries instead of diesel engines could work long-distance services to and from Hull.

This will happen, as electric trains to London, would be a dream for a marketing man or woman.

Will The InterCity 225 Trains Lose Some First Class Seats?

This may happen, so that the seating layout in both trains is almost identical.

I’m certain, that it could be arranged, that seat numbers in both trains could have a similar position.

This would mean that if an InterCity 225 train replaced a Class 801 train, there wouldn’t need to be a seat reallocation.

Could InterCity 225 Trains Be Fitted With Emergency Batteries?

If LNER thought they were needed, I’m sure that this would be possible and Hyperdrive Innovation would oblige!

Conclusion

British Rail last hurrah, is giving Hitachi’s latest trains, a run for their money!

Thoughts On Digital Signalling On The East Coast Main Line

I came up to Doncaster yesterday on a new Hull Trains Class 802 train.

According to my pocket dynamometer car, the train seemed to be at or nearly at 125 mph, most of the time I looked from possibly around Stevenage to just South of Doncaster.

I came back today on an LNER Class 801 train and the train’s performance seemed very similar.

I also noted the following.

  • The two stops at Newark and Peterborough, took seven and nine minutes respectively from the start of slowing for the station until back up to speed.
  • Between Peterborough and Stevenage the train kept below a maximum of 110 mph.
  • The train went through the two tunnels before Welwyn North station and the station itself at 75 mph.
  • I timed the train at 100 mph over the Digswell Viaduct, when it reached the South side after accelerating on the viaduct.
  • 90 mph was maintained between Potters Bar and New Southgate stations.
  • Speed gradually reduced from New Southgate into Kings Cross.

Note.

  1. 125 mph is the maximum allowable speed of the train.
  2. The 110 mph running was probably to be compatible with the Class 387 trains.
  3. I will do the trip again and get some accurate figures.

It appears to me, that the driver was obeying a simple but fast plan.

The Wikipedia entry for the East Coast Main Line, says this about the opiating speed of the line, with the new trains.

Increasing maximum speeds on the fast lines between Woolmer Green and Dalton-on-Tees up to 140 mph (225 km/h) in conjunction with the introduction of the Intercity Express Programme, level crossing closures, ETRMS fitments, OLE rewiring and the OLE PSU – est. to cost £1.3 billion (2014). This project is referred to as “L2E4” or London to Edinburgh (in) 4 Hours. L2E4 examined the operation of the IEP at 140 mph on the ECML and the sections of track which can be upgraded to permit this, together with the engineering and operational costs

It also says this about the implementation of digital signalling.

A new Rail operating centre (ROC), with training facilities, opened in early 2014 at the “Engineer’s Triangle” in York. The ROC will enable signalling and day-to-day operations of the route to be undertaken in a single location. Signalling control/traffic management using ERTMS is scheduled to be introduced from 2020 on the ECML between London King’s Cross and Doncaster – managed from the York ROC.

The signalling could probably work in one of two ways.

  • The signalling tells the driver the required speed and they drive the train accordingly.
  • The signalling drives the train and the driver monitors what is happening.

Both methods are used in the UK.

A Possible London Kings Cross and Leeds Service

The combined affect of both track and signalling improvements is illustrated by this simple calculation.

  • As Dalton-on-Tees is North of Doncaster, the route between Woolmer Green and Doncaster should be possible to be run at 140 mph
  • Woolmer Green and Doncaster stations are 132.1 miles apart.
  • Non-stop York and London Kings Cross trains are currently timed at 70 minutes between Doncaster and Woolmer Green stations.
  • This is an average speed of 113.2 mph.

If 140 mph could be maintained between Doncaster and Woolmer Green, the section of the journey would take 56.6 minutes, which is a saving of 13.4 minutes.

Consider.

  • The fastest current trains between London Kings Cross and Leeds take between two hours and twelve minutes and two hours and fifteen minutes.
  • I suspect that the extra tracks into Kings Cross, that are currently being built will save a few minutes.
  • There must be some savings to be made between Doncaster and Leeds
  • There must be some savings to be made between London Kings Cross and Woolmer Green.
  • There could be a rearrangement of stops.

I think it is highly likely that in the future, there will be at least one train per hour (tph) between London Kings Cross and Leeds, that does the trip in two hours.

  • There is no reason why all London Kings Cross and Leeds trains could not take two hours.
  • London Kings Cross and Doncaster could be several minutes under an-hour-and-a-half.
  • High Speed Two is predicting one hour and twenty-one minutes for their future service  between London Euston and Leeds, which is a saving of 38 minutes.
  • London and Leeds in two hours will attract passengers.

There will be serious competition between London and Leeds.

Other Timing Improvements

I also think these times would be possible

  • London Kings Cross and Bradford Forster Square – two hours and thirty minutes
  • London Kings Cross and Harrogate – two hours and thirty minutes
  • London Kings Cross and Huddersfield – two hours and twenty minutes
  • London Kings Cross and Hull – two hours and thirty minutes
  • London Kings Cross and Middlesbrough – two hours and thirty minutes
  • London Kings Cross and Scarborough – two hours and thirty minutes
  • London Kings Cross and Sheffield – two hours
  • London Kings Cross and Skipton – two hours and thirty minutes
  • London Kings Cross and York – two hours

I would be fairly certain that London Kings Cross and Huddersfield could be slowed by ten minutes, which would give the London Kings Cross and Yorkshire a certain symmetry.

  • London Kings Cross and Leeds and York would take two hours.
  • London Kings Cross and all the others would take two hours and thirty minutes.

It would probably make arrangement of a fast timetable easier.

Overhauls for LNER’s Remaining Class 91s And Mk 4s

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

This is the introductory paragraph.

Eversholt Rail, which owns the trains, has confirmed that 12 London North Eastern Railway Class 91s and the remaining Mk 4 coaches will undergo overhauls at Wabtec Rail, Doncaster.

It had been expected, that LNER would purchase more trains, as I wrote about in More New Trains On LNER Wish List.

The article gives more details of the trains to be retained.

  • Twelve Class 91 locomotives, seven rakes of Mark 4 coaches and two spare coaches will be retained.
  • They will be confined to routes between London Kings Cross and Bradford, Leeds, Skipton and York.

How many trains will be needed to cover these routes?

  • Trains take two hours and fifteen minutes between London Kings Cross and Leeds and run at a frequency of two trains per hour (tph)
  • Trains take two hours and twenty-one minutes between London Kings Cross and York and run hourly.
  • I suspect that a round trip to Leeds or York can be five hours.

So a crude analysis says, that will mean fifteen trains will be needed,

But some of these trains will be extended past Leeds.

These are, electrification status and the times and distances between Leeds and the final destinations.

  • Bradford – Electrified – 22 minutes – 13.5 miles
  • Harrogate – Not Electrified – 40 minutes – 18 miles
  • Huddersfield – Not Electrified – 33 minutes – 17 miles
  • Skipton – Electrified  – 45 minutes – 26 miles

It appears that the following is true.

  • Trains serving Harrogate and Huddersfield must be worked by bi-mode Class 800 trains.
  • Trains serving Bradford and Skipton could be worked by InterCity 225 trains or an all-electric nine-car Class 801 train.

Note.

  1. Some times are those taken by LNER services and some are estimates from TransPennine Express.
  2. I have assumed 8-10 minutes for the Split-and-Join at Leeds and included it in the times.
  3. Class 800 trains seem to take around ten minutes to turnround at Harrogate.
  4. Times between London Kings Cross and Doncaster will decrease by a few minutes, with the addition of digital in-cab signalling on the route, which will allow 140 mph running by InterCity 225s, Class 800 trains and Class 801 trains.

I estimate that it will be possible for an InterCity 225, Class 800 train or Class 801 train to do a round trip between London Kings Cross and Bradford, Harrogate, Huddersfield or Skipton in six hours.

The round trip between London Kings Cross and York will be the five hours, I estimated earlier.

Wikipedia also says this.

LNER expects to introduce two-hourly services to Bradford and a daily service to Huddersfield in May 2020 when more Azuma trains have been introduced.

So would the pattern of trains to Leeds/York be as follows?

  • One tph – One pair of five-car Class 800 trains to Leeds, of which some or all split and join at Leeds, with one train going to and from Harrogate and the other going to and from Huddersfield.
  • One tph per two hours (tp2h) – An InterCity 225 or nine-car Class 801 train to Leeds, of which some or all are extended to Bradford.
  • One tp2h – An InterCity 225 or nine-car Class 801 train to Leeds, of which some or all are extended to Skipton.
  • One tph – An InterCity 225 or nine-car Class 801 train to York.

I estimate that it will be possible for an InterCity 225, Class 800 train or Class 801 train to do a round trip between London Kings Cross and Bradford, Harrogate, Huddersfield or Skipton in six hours.

This would need the following trains.

  • Six pairs of five-car Class 800 trains for the Harrogate and Huddersfield services.
  • Six full size all electric trains, which could be an InterCity 225, a nine-car Class 801 train or a pair of five Class 801 trains, for Bradford and Skipton services.
  • Five full size all electric trains, which could be an InterCity 225, a nine-car Class 801 train or a pair of Class 801 trains, for York services.

So why have LNER changed their mind and are retaining the InterCity 225?

Are InterCity 225 Trains Already Certified For 140 mph Running?

I wouldn’t be surprised, if a large part of the certification work for this had been done for 140 mph running and for it to be allowed, it needs digital in-cab signalling to be installed on the East Coast Main Line.

The Wikipedia entry for the InterCity 225 says this about the train’s performance.

The InterCity 225 has a top service speed of 140 mph (225 km/h); during a test run in 1989 on Stoke Bank between Peterborough and Grantham an InterCity 225 reached 162 mph (260.7 km/h). However, except on High Speed 1, which is equipped with cab signalling, British signalling does not allow trains to exceed 125 mph (201 km/h) in regular service, due to the impracticality of correctly observing lineside signals at high speed.

The Wikipedia entry for the East Coast Main Line says this about the future signalling.

A new Rail operating centre (ROC), with training facilities, opened in early 2014 at the “Engineer’s Triangle” in York. The ROC will enable signalling and day-to-day operations of the route to be undertaken in a single location. Signalling control/traffic management using ERTMS is scheduled to be introduced from 2020 on the ECML between London King’s Cross and Doncaster – managed from the York ROC.

A small fleet of InterCity 225 trains could be the ideal test fleet to find all the glitches in the new signalling.

Are InterCity 225 trains Already Certified To Run To Bradford and Skipton?

If they are, then that is another problem already solved.

A Fleet Of Seven Trains Would Cover Bradford And Skipton Services

Six trains are needed to run a one tp2h service to both Bradford and Skipton, so they could fully cover one tp2h to Bradford and occasional trains to Skipton with a spare train and one in maintenance.

Using InterCity 225s To Bradford and Skipton Would Not Require A Split-And-Join At Leeds

The number of trains that would Split-and-Join at Leeds would be only two tph instead  of four tph, which would be simpler with less to go wrong.

Not Enough Five-Car Bi-Mode Class 800 Trains

LNER’s full fleet of Azumas will be as follows.

  • 13 – Nine-car bi-mode Class 800 trains.
  • 10 – Five-car bi-mode Class 800 trains.
  • 30 – Nine-car electric Class 801 trains.
  • 12 – Five-car electric Class 801 trains.

This would appear to be a major problem, if Harrogate and Huddersfield were to be served hourly by Class 800 trains, existing services are to be maintained or even increased to Hull and Lincoln and extra services are to be added to Middlesbrough and perhaps Nottingham and other destinations.

The InterCity 225s only help indirectly, if they provided the London Kings Cross and Bradford and Skipton services.

Conversion Of Class 800 and Class 801 Trains To Regional Battery Trains

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

For LNER, they will be useful for any Journey under about 90 kilometres or 56 miles.

The trains should be able to serve these routes.

  • Leeds and Harrogate and back – 36 miles
  • Leeds and Huddersfield and back – 34 miles
  • Newark and Lincoln and back – 33 miles
  • Northallerton and Middlesbrough and back – 42 miles

Whilst Class 800 trains and Class 801 trains are converted, the InterCity 225 trains would act as valuable cover on services like London to Leeds and York.

Conclusion

I think it is a good plan.

Could Some of Hitachi’s Existing Trains In The UK Be Converted To Battery-Electric Trains?

The last five fleets of AT-300 trains ordered for the UK have been.

Each fleet seems to be tailored to the needs of the individual operator, which is surely as it should be.

I can make some observations.

Fast Electric Trains

Both all-electric fleets on the list, will run on routes, where speed will be important.

  • The Avanti West Coast Class 807 trains on the West Coast Main Line, will have to be able to keep up keep with the Class 390 trains, that have the advantage of tilt for more speed.
  • The East Coast Trains Class 803 trains on the East Coast Main Line, will have to work hard to maintain a demanding schedule, as I outlined in Thoughts On East Coast Trains.

Any reduction in weight will improve the acceleration.

  • The seven tonne MTU 12V 1600 R80L diesel engines can be removed to reduce the weight.
  • As a five-car Class 800 train with three diesel engine weighs 243 tonnes, this could save nearly 9 % of the train’s weight.
  • East Coast Trains feel they need an appropriately-sized battery for emergency hotel power. Could this be because the catenary is not as good on the East Coast Main Line as on the West?
  • Perhaps, Avanti West Coast feel a battery is not needed, but they could obviously fit one later. Especially, if there was already a ready-wired position underneath the train.

The extra acceleration given by 100% electric operation, must make all the difference in obtaining the required performance for the two routes.

Why Four Diesel Engines In A Class 810 Train?

The Class 810 trains are an update of the current Class 800/Class 802 trains. Wikipedia described the differences like this.

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 due to platform length constraints at London St Pancras.

Additionally, in this article in the October 2019 Edition of Modern Railways, which is entitled EMR Kicks Off New Era, this is said.

The EMR bi-modes will be able to run at 125 mph in diesel mode, matching Meridian performance in a step-up from the capabilities of the existing Class 80x units in service with other franchises.

The four diesel engines would appear to be for more power, so that these trains will be able to run at 125 mph on diesel.

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

  • At 125 mph a train will in an hour travel 125 miles.
  • In that hour the train will need 125 x 5 x 3.42 = 2137.5 kWh
  • This means that the total power of the four diesel engines must be 2137.5,
  • Divide 2137.5 by four and each diesel must be rated at 534.4 kW to provide the power needed.

The MTU 12V 1600 R80L diesel engine is described in this datasheet on the MTU web site.

Note on the datasheet, there is a smaller variant of the same engine called a 12V 1600 R70, which has a power output of 565 kW, as compared to the 700 kW of the 12V 1600 R80L.

The mass of the engines are probably at the limits of the range given on the datasheet.

  • Dry – 4500-6500 Kg
  • Wet – 4700-6750 Kg

It would appear that the less-powerful 12V 100 R70 is about two tonnes lighter.

So where will four engines be placed in a Class 810 train?

  • The five-car Class 800 and Class 802 trains have diesel-engines in cars 2, 3 and 4.
  • The nine-car Class 800 and Class 802 trains have diesel-engines in cars 2,3, 5, 7 and 8.
  • It appears that diesel-engines aren’t placed under the driver cars.
  • Five-car AT-300 trains generally have a formation of DPTS+MS+MS+MC+DPTF.
  • The car length in the Class 810 trains are two metres shorter than those in other trains.

Could it be that the intermediate cars on Class 810 trains will be an MC car, which has both First and Standard Class seating and two identical MS cars both with two smaller diesel engines?

  • The two smaller diesel engines will be about 2.6 tonnes heavier, than a single larger engine.
  • Only one fuel tank and other gubbins will be needed.
  • The shorter car will be lighter in weight.
  • MTU may have designed a special diesel engine to power the train.

I would suspect that a twin-engined MS car is possible.

Could The Battery And The Diesel Engine Be Plug-Compatible?

I found 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.

The document may date from 2014, but it gives a deep insight into the design of Hitachi’s trains.

I will take a detailed look at the traction system as described in the document.

This schematic of the traction system is shown.

Note BC is described as battery charger.

This is said in the text, where GU is an abbreviation for generator unit.

The system can select the appropriate power source from either the main transformer or the GUs. Also, the size and weight of the system were minimized by designing the power supply converter to be able to work with both power sources. To ensure that the Class 800 and 801 are able to adapt to future changes in operating practices, they both have the same traction system and the rolling stock can be operated as either class by simply adding or removing GUs. On the Class 800, which is intended to run on both electrified and non-electrified track, each traction system has its own GU. On the other hand, the Class 801 is designed only for electrified lines and has one or two GUs depending on the length of the trainset (one GU for trainsets of five to nine cars, two GUs for trainsets of 10 to 12 cars). These GUs supply emergency traction power and auxiliary power in the event of a power outage on the catenary, and as an auxiliary power supply on non-electrified lines where the Class 801 is in service and pulled by a locomotive. This allows the Class 801 to operate on lines it would otherwise not be able to use and provides a backup in the event of a catenary power outage or other problem on the ground systems as well as non-electrified routes in loco-hauled mode.

This is all very comprehensive.

Note that the extract says, that both the Class 800 trains and Class 801 trains have the same traction control system. A section called Operation in the Wikipedia entry for the Class 802 train, outlines the differences between a Class 802 train and a Class 800 train.

The Class 802s are broadly identical to the Class 800 bi-mode trains used in the Intercity Express Programme, and are used in a similar way; they run as electric trains where possible, and are equipped with the same diesel generator engines as the Class 800. However, they utilise higher engine operating power – 700 kW (940 hp) per engine as opposed to 560 kW (750 hp) – and are fitted with larger fuel tanks to cope with the gradients and extended running in diesel mode expected on the long unelectrified stretches they will operate on.

I would assume that the differences are small enough, so that a Class 802 train, can use the same traction control system, as the other two train classes.

The Hitachi document also describes the Train Management and Control System (TCMS), the function of which is described as.

Assists the work of the train crew; a data communication function that aids maintenance work; and a traction drive system that is powered by the overhead lines (catenaries) and GUs.

Several trains have been described as computers on wheels. That could certainly be said about these trains.

There would appear to be a powerful Automatic Train Identification Function.

To simplify the rearrangement and management of train configurations, functions are provided for identifying the train (Class 800/801), for automatically determining the cars in the trainset and its total length, and for coupling and uncoupling up to 12 cars in normal and 24 cars in rescue or emergency mode.

Now that would be a sight – One nine-car train rescuing another!

I would assume that this Automatic Train Identification Function has already been updated to add the Class 802 trains and it would appear to me, as a very experienced computer programmer, that in future it could be further updated to cater for the following.

  • New classes of trains like the future Class 803 and Class 810 trains.
  • The fitting of batteries instead of diesel engines.

Could the Function even be future-proofed for hydrogen power?

There are two main ways for trains to operate when the diesel engine in a car has been replaced by a battery.

  1. A plug-compatible battery module is designed, that in terms of function looks exactly like a diesel engine to the TCMS and through that the train crew.
  2. The car with a battery becomes a new type of car and the TCMS is updated to control it, in an appropriate manner.

Both methods are equally valid.

I would favour the first method, as I have come across numerous instances in computer programming, engineering and automation, where the method has been used successfully.

The method used would be Hitachi’s choice.

What Size Of Battery Could Be Fitted In Place Of The Diesel Engine?

Consider.

  • The wet mass of an MTU 16V 1600 R80L diesel engine commonly fitted to AT-300 trains of different types is 6750 Kg or nearly seven tonnes.
  • My engineering knowledge would suggest, that it would be possible to replace the diesel engine with an inert lump of the same mass and not affect the dynamics of the train.

So could it be that a plug-compatible battery module can be fitted, so long as it doesn’t exceed the mass of the diesel engine it replaces?

For an existing Class 800 or Class 802 train, that limit could be seven tonnes.

But for East Coast Train’s Class 803 train, that size would probably be decided by the required train performance.

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.

This table can be calculated of battery weight, low capacity and high capacity.

  • 1 tonne – 100 kWh – 265 kWh
  • 2 tonne – 200 kWh – 530 kWh
  • 3 tonne – 300 kWh – 895 kWh
  • 4 tonne – 400 kWh – 1060 kWh
  • 5 tonne – 500 kWh – 1325 kWh
  • 6 tonne – 600 kWh – 1590 kWh
  • 7 tonne – 700 kWh – 1855 kWh

As energy densities are only going to improve, the high capacity figures are only going to get larger.

If you look at the design of the Class 803 trains, which could have three positions for diesel engines or batteries, the designers of the train and East Coast Trains can choose the battery size as appropriate for the following.

  • Maximum performance.
  • Power needs when halted in stations.
  • Power needs for emergency power, when the wires come tumbling down.

I suspect, they will fit only one battery, that is as small as possible to minimise mass and increase acceleration, but large enough to provide sufficient power, when needed.

Conversion Of A Five-Car Class 800/Class 802 Train To Battery-Electric Operation

If Hitachi get their design right, this could be as simple as the following.

  • Any of the three MTU 12V 1600 R80L diesel engines is removed, from the train.
  • Will the other diesel related gubbins, like the fuel tank be removed? They might be left in place, in case the reverse conversion should be needed.
  • The new battery-module is put in the diesel engine’s slot.
  • The train’s computer system is updated.
  • The train is tested.

It should be no more difficult than attaching a new device to your personal computer. Except that it’s a lot heavier.

As there are three diesel engines, one, two or three could be replaced with batteries.

Trains would probably be able to have a mixture of diesel engines and battery modules.

A Class 802 train with one diesel engine and two five-tonne batteries would have the following power sources.

  • 25 KVAC overhead electrification.
  • A 700 kW diesel engine.
  • Two five-tonne batteries of between 500 kWh and 1325 kWh.

With intelligent software controlling the various power sources, this train could have a useful range, away from the electrification.

Conversion Of A Five-Car Class 810 Train To Battery-Electric Operation

The process would be similar to that of a Class 800/Class 802 Train, except there would be more possibilities with four engines.

It would also need to have sufficient range to bridge the gaps in the electrification.

Perhaps each train would have the following power sources.

  • 25 KVAC overhead electrification.
  • Two 565 kW diesel engines.
  • Two four-tonne batteries of between 400 kWh and 1060 kWh.
  • Batteries might also be placed under the third intermediate car.

I estimate that with 400 kWh batteries, a train like this would have a battery range of sixty-five miles.

Conclusion

The permutations and combinations would allow trains to be tailored to the best compromise for a train operating company.

When The New Newport Railway Line To Cater For Major Events Is Set To Open

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

If you’ve ever been to a major event at the Principality Stadium in Cardiff, as I have a couple of times, you’ll know that getting your train back to England can be a long wait.

So the Welsh have come up with a cunning plan to build a staging area, where they can hold trains near the former Llanwern steelworks site at Newport.

  • It will be 2.4 km. long.
  • I estimate that a nine-car Class 801 train is 234 metres long and holds 611 passengers, so the siding can hold ten trains which have a capacity of over six thusand passengers.
  • It is part of a £50million plan for a new Llanwern station, which is part of the South Wales Metro.
  • It will also be used for the testing of trains. It is very handy for CAF’s Newport factory.

This Google Map shows the site, with CAF’s factory highlighted.

Note the South Wales Main Line running along the North of the massive steelworks site. So if the staging area, is built between the main line and the steelworks site, which contains the CAF factory, it will be convenient for both uses.

This looks to be a good plan, that will solve more multiple problems and needs.

A Better News Day For New Trains

Yesterday, was a better news day for new trains, with articles with these headlines.

All are significant for passengers.

Class 710 Trains

The authorisation of the Class 710 trains is particular importance to me, as they will be running locally to where I live.

It will be a couple of months before they enter passenger service.

But the trains have mainly been delayed by software problems and now that appears to have been fixed and as there are twenty trains already built, I could see them entering service, as soon as drivers have been trained.

It should be noted that eight trains are needed for the Gospel Oak to Barking Line and six for the Watford DC Line, so if twenty have been built, I would expect that these two routes could be converted to the new trains by the summer.

Class 801 Trains

LNER’s Class 801 trains will be a significant introduction, as they will enable the cascade of the Mark 4 coaches to other operators, like Trains for Wales and East Midlands Railway.
