Could Battery-Electric Hitachi Trains Work TransPennine Express’s Services?

Before I answer this question, I will lay out the battery-electric train’s specification.

Hitachi’s Proposed Battery Electric Train

Based on information in an article in Issue 898 of Rail Magazine, which is entitled Sparking A Revolution, the specification of Hitachi’s proposed battery-electric train is given as follows.

  • Based on Class 800-802/804 trains or Class 385 trains.
  • Range of 55-65 miles.
  • Operating speed of 90-100 mph
  • Recharge in ten minutes when static.
  • A battery life of 8-10 years.
  • Battery-only power for stations and urban areas.
  • Trains are designed to be created by conversion of existing Class 80x trains

For this post, I will assume that the train is five cars long. This is the length of TransPennine Express’s Class 802 trains.

TransPennine Express’s Services

These are TransPennine Express services that run in the North of England and to Scotland.

I shall go through all the services and see how they would be affected by Hitachi’s proposed battery-electric train.

Liverpool Lime Street And Edinburgh

  • The service runs at a frequency of one train per hour (tph)
  • Intermediate stations are Newton-le-Willows, Manchester Victoria, Huddersfield, Leeds, York, Darlington, Durham, Newcastle and Morpeth

The service is 305 miles long and takes four hours and 25 minutes.

The route can be divided into sections, some of which are electrified and some of which are not!

  • Liverpool Lime Street and Manchester Victoria – 32 miles – Electrified
  • Manchester Victoria and Huddersfield  – 26 miles – Not Electrified
  • Huddersfield and Dewsbury – 8 miles – Not Electrified
  • Dewsbury and Leeds – 9 miles – Not Electrified
  • Leeds and Colton Junction – 20 miles – Not Electrified
  • Colton Junction and Edinburgh – 220 miles – Electrified

Note that the distance between Manchester Victoria and Colton Junction, which is the only section of the route without electrification is sixty-three miles, which is just within the 55-65 mile battery range of Hitachi’s proposed battery-electric train.

That is too close for my liking, as what happens, if the train gets delayed by an operational incident.

In this article on the BBC, which was published in August 2019 and is entitled Detailed TransPennine £2.9bn Rail Upgrade Plans Unveiled, the following is said.

  • The route between Huddersfield and Dewsbury will be electrified.
  • Parts of this route will have two extra tracks.
  • The plans will be going to full consultation, later in the year.

This would mean that a route summary would be like this.

  • Liverpool Lime Street and Manchester Victoria – 32 miles – Electrified
  • Manchester Victoria and Huddersfield  – 26 miles – Not Electrified
  • Huddersfield and Dewsbury – 8 miles – Electrified
  • Dewsbury and Colton Junction – 29 miles – Not Electrified
  • Colton Junction and Edinburgh – 220 miles – Electrified

The two sections without electrification are well within the 55-65 mile battery range of Hitachi’s proposed battery electric train.

It should also be noted that the electrification between Newcastle and Edinburgh is rather down on power and needs upgrading.

I would suspect that Hitachi’s proposed battery electric train could handle this power deficiency by using the batteries.

Liverpool Lime Street And Scarborough

  • The service runs at a frequency of one tph
  • Intermediate stations are Lea Green, Manchester Victoria, Stalybridge, Huddersfield, Leeds, Garforth, York, Malton and Seamer

The service is 142 miles long and takes two hours and 58 minutes.

The route can be divided into sections, some of which are electrified and some of which are not!

  • Liverpool Lime Street and Manchester Victoria – 32 miles – Electrified
  • Manchester Victoria and Huddersfield  – 26 miles – Not Electrified
  • Huddersfield and Dewsbury – 8 miles – Not Electrified
  • Dewsbury and Leeds – 9 miles – Not Electrified
  • Leeds and Colton Junction – 20 miles – Not Electrified
  • Colton Junction and York – 6 miles – Electrified
  • York and Scarborough – 42 miles – Not Electrified

Between Liverpool Lime Street and Colton Junction, the route is identical to the Liverpool Lime Street and Edinburgh service.

The improvement of the section between Huddersfield and Dewsbury will also benefit this service and mean that a route summary would be like this.

  • Liverpool Lime Street and Manchester Victoria – 32 miles – Electrified
  • Manchester Victoria and Huddersfield  – 26 miles – Not Electrified
  • Huddersfield and Dewsbury – 8 miles – Electrified
  • Dewsbury and and Colton Junction – 29 miles – Not Electrified
  • Colton Junction and York – 6 miles – Electrified
  • York and Scarborough – 42 miles – Not Electrified

As Hitachi’s proposed battery-electric train has a range of 55-65 miles on battery power, it looks to me that this service could be handled by the train.

It would need a Fast Charge system at Scarborough to recharge the batteries to be able to return to York.

But, as the timetable allows a generous turn-round, fully-charging the batteries shouldn’t be a problem.

Manchester Airport And Newcastle

  • The service runs at a frequency of one tph
  • Intermediate stations are Manchester Piccadilly, Manchester Oxford Road, Manchester Victoria, Huddersfield, Dewsbury, Leeds, York, Northallerton, Darlington, Durham and Chester-le-Street

The service is 162 miles long and takes three hours and one minute.

The route can be divided into sections, some of which are electrified and some of which are not!

  • Manchester Airport and Manchester Victoria – 13 miles – Electrified
  • Manchester Victoria and Huddersfield  – 26 miles – Not Electrified
  • Huddersfield and Dewsbury – 8 miles – Not Electrified
  • Dewsbury and Leeds – 9 miles – Not Electrified
  • Leeds and Colton Junction – 20 miles – Not Electrified
  • Colton Junction and Edinburgh – 86 miles – Electrified

Between Manchester Victoria and Colton Junction, the route is identical to the two Liverpool Lime Street services, that I discussed previously.

The improvement of the section between Huddersfield and Dewsbury will also benefit this service and mean that Hitachi’s proposed battery-electric train could handle this route with ease.

Manchester Airport And Redcar Central

  • The service runs at a frequency of one tph
  • Intermediate stations are Gatley, Manchester Piccadilly, Manchester Oxford Road, Manchester Victoria, Huddersfield, Dewsbury, Leeds, York, Thirsk, Northallerton, Yarm, Thornaby and Middlesbrough

The service is 162 miles long and takes three hours and fifteen minutes.

The route can be divided into sections, some of which are electrified and some of which are not!

  • Manchester Airport and Manchester Victoria – 13 miles – Electrified
  • Manchester Victoria and Huddersfield  – 26 miles – Not Electrified
  • Huddersfield and Dewsbury – 8 miles – Not Electrified
  • Dewsbury and Leeds – 9 miles – Not Electrified
  • Leeds and Colton Junction – 20 miles – Not Electrified
  • Colton Junction and Northallerton – 35 miles – Electrified
  • Northallerton and Redcar Central – 29 miles – Not Electrified

Between Manchester Victoria and Colton Junction, the route is identical to the previously discussed services.

The improvement of the section between Huddersfield and Dewsbury will also benefit this service and mean that Hitachi’s proposed battery-electric train could handle this route with ease.

As with the Scarborough service, a Fast-Charge system would probably be needed at Redcar Central.

Manchester Piccadilly And Hull

  • The service runs at a frequency of one tph
  • Intermediate stations are Stalybridge, Huddersfield, Leeds, Selby and Brough

The service is 94 miles long and takes two hours and four minutes.

The route can be divided into sections, some of which are electrified and some of which are not!

  • Manchester Piccadilly and Huddersfield  – 25 miles – Not Electrified
  • Huddersfield and Dewsbury – 8 miles – Not Electrified
  • Dewsbury and Leeds – 9 miles – Not Electrified
  • Leeds and Hull – 52 miles – Not Electrified

Between Huddersfield and Leeds, the route is identical to the previously discussed services.

The improvement of the section between Huddersfield and Dewsbury will also benefit this service and mean that Hitachi’s proposed battery-electric train should be able to handle this route.

As with the Scarborough and Redcar Central services, a Fast-Charge system would probably be needed at Hull.

Manchester Piccadilly And Huddersfield

  • The service runs at a frequency of one tph
  • Intermediate stations are Stalybridge, Mossley, Greenfield, Marsden and Slaithwaite

The service is 25 miles long and takes forty-three minutes.

The route is without electrification.

Hitachi’s proposed battery-electric train should be able to handle this route with ease.

The train could charge at either end using the electrification.

Huddersfield And Leeds

  • The service runs at a frequency of one tph
  • Intermediate stations are Deighton, Mirfield, Ravensthorpe, Dewsbury, Batley, Morley and Cottingley

The service is 17 miles long and takes thirty-six minutes.

Hitachi’s proposed battery-electric train should be able to handle this route with ease.

The train could charge at Leeds using the electrification.

Manchester Airport And Cleethorpes

  • The service runs at a frequency of one tph
  • Intermediate stations are Manchester Piccadilly, Stockport, Sheffield, Meadowhall Interchange, Doncaster, Scunthorpe, Barnetby, Habrough and Grimsby Town

The service is 124 miles long and takes two hours and fifty-eight minutes.

he route can be divided into sections, some of which are electrified and some of which are not!

  • Manchester Airport and Stockport – 16 miles – Electrified
  • Stockport and Sheffield  – 37 miles – Not Electrified
  • Sheffield and Doncaster – 19 miles – Not Electrified
  • Doncaster and Cleethorpes – 52 miles – Not Electrified

There would need to be some en route charging and surely the easiest way to achieve this would be to extend the electrification at Doncaster to Sheffield.

As with the other services, a Fast-Charge system would probably be needed at Cleethorpes.

Manchester Airport And Glasgow Central Or Edinburgh Waverley Via Preston

This service is all-electric.

Conclusion

Hitachi’s proposed battery-electric train can handle all of TransPennine’s routes without using one drop of diesel.

What I have found interesting, is that the eight miles of electrification between Huddersfield and Dewsbury appears to make the operation of a battery-electric train a lot easier.

It looks like someone at Hitachi and Network Rail have taken a calculator to a decent hostelry and worked out a cunning plan!

Does The Acceleration Of The TransPennine Upgrade Have Anything To Do With Boris?

In Issue 885 of Rail Magazine, which was published on 14/08/19, there is an article, which is entitled Johnson Vows To Build New Manchester-Leeds Line, where this is said.

New Prime Minister Boris Johnson has pledged to fund a new line as part of Northern Powerhouse Rail in what has been described by leaders in the North as a “seminal moment”.

Speaking in Manchester on July 27, Johnson said. “I want to be the PM who does with Northern Powerhouse Rail what we did with Crossrail in London. And today I’m going to deliver on my commitment to that vision with a pledge to fund the Leeds to Manchester route.

“It will be up to local people and us to come to an agreement on the exact proposal they wat – but I have tasked officials to accelerate their work on these plans so that we are ready to do a deal in the autumn.”

Since Boris’s speech, plans for improvements between Huddersfield and Dewsbury have been announced and now it seems that Network Rail have published plans for full electrification between Huddersfield and Leeds, as I discussed in Is There Going To Be Full Electrification Between Leeds And Huddersfield?.

Whether you are for or against Boris, he certainly seems to have got action from Network Rail.

Is There Going To Be Full Electrification Between Leeds And Huddersfield?

This article on Rail Technology Magazine is dated 23/08/19 and is entitled Network Rail Reveals Detailed £2.9bn Upgrade Plans For TransPennine Route and it prompted me to write this post of the same name.

The Rail Technology Magazine article talks about a comprehensive upgrade to the Huddersfield Line is planned that includes.

  • Improvement between Huddersfield and Westtown
  • Grade separation or a tunnel at Ravensthorpe
  • Rebuilding and electrification of eight miles of track.
  • Possible doubling the number of tracks from two to four.
  • Improved stations at Huddersfield, Deighton, Mirfield and Ravensthorpe.

I have now found this document on the Network Rail web site, which is entitled Huddersfield to Westtown (Dewsbury).

This statement is included under proposals.

Electrification of the railway from Huddersfield to Ravensthorpe – and right through to Leeds.

Because there is a dash in the words, has electrification to Leeds, been a recent addition?

It certainly doesn’t fit with the Rail Technology Magazine article.

It also doesn’t fit with this article on the BBC, which is dated 20/08/19 and is entitled Detailed TransPennine £2.9bn Rail Upgrade Plans Unveiled.

Electrification is mentioned in the second paragraph.

Network Rail has also announced it intends to electrify the line between Huddersfield and Dewsbury and double the number of tracks from two to four.

And in the sixth paragraph.

Network Rail said the proposed major overhaul and electrification work would be carried out on an 8-mile (13km) section of the route, with the “first round” of consultations starting with those living closest to the railway.

The two news sites seem to have used the same source.

The BBC also uses this map, that I have copied from the Network Rail document

Note the railway lines shown in red. Are these the ones to be electrified? As they go from Huddersfield to Westtown, I think the answer is probably in the affirmative.

I seems to me, that Rail Technology Magazine and the BBC are using a common source and could it be an earlier version of the Network Rail document.

But the map, I have shown, shows the electrification only going as far as Westtown, despite coming from a document, that states twice that the electrification is going as far as Leeds.

It is certainly sloppy documentation.

Track Layouts

This document on the Digital Railway web site is dated 16/08/18 and is entitled Transpennine Route Upgrade SDO1 ETCS – Analysis.

Significantly, it is written by the Digital Railway – Joint Development Group (JDG), which consists of representatives of Siemens, Hitachi, ARUP and Network Rail.

It is mainly about using digital signalling called ETCS on the Transpennine Route, but it does give these track layouts between Huddersfield and Dewsbury.

This is the current layout.

There is also this full four-track layout, which I assume was the original plan.

It is more complicated and involved the building of bridges in the area of Ravensthorpe station.

There is also a reduced four-track layout, which I assume was developed as the track analysis progressed.

It is not a massive upgrade from the current layout.

As I see it, if the reduced layout can handle the required number of services, it has major advantages over the full scheme.

  • There are no changes to track  layout between Ravensthorpe and Dewsbury stations.
  • Rebuilding Ravensthorpe station should be a smaller project.
  • The current and reduced layout have three tracks between Mirfield and Ravensthorpe stations.
  • There are no expensive new bridges to be built.

To make the scheme work there is a small amount of bi-directional running on the centre track, which is made possible by using digital signalling on the route.

Track Usage

By using bi-directional running on the centre track between Ravensthorpe and Mirfield stations, which is controlled by ETCS, the track layout is simplified, with three tracks instead of four.

  • Slow trains from Huddersfield to Dewsbury will dive under the Brighouse lines and call in/pass Platform 1 at Mirfield station before going straight on to Ravensthorpe and Dewsbury. This is as trains do now.
  • Slow trains from Dewsbury to Huddersfield will use the centre track from East to West and call in/pass Platform 2 at Mirfield station before turning South-West  on to Huddersfield. This is as trains do now.
  • Fast trains from Huddersfield to Dewsbury will call in/pass Platform 3 at Mirfield station and then cross over to the top track and go straight on to Ravensthorpe and Dewsbury.
  • Fast trains from Dewsbury to Huddersfield will use the centre track from East to West and call in/pass Platform 4 at Mirfield station before turning South-West  on to Huddersfield.
  • Trains from Brighouse  to Wakefield will call in/pass Platform 1 at Mirfield station and then cross to the centre track and go straight on to Wakefield. This is as trains do now.
  • Trains from Wakefield to Brighouse will use the centre track from East to West and call in/pass Platform 2 at Mirfield station and go straight on to Brighouse.

Note.

  1. Platforms at Mirfield station are numbered 1 to 4 from the North
  2. The slow lines between Mirfield and Huddersfield are shown in black.
  3. The fast lines between Mirfield and Huddersfield are shown in blue.
  4. Passengers can use Platforms 1/2 as a cross-platform interchange between slow Huddersfield-Leeds and Brighouse-Wakefield services.

I also think it likely, that the proposed layout will improve the timetable.

Does The Reduced Layout Produce A Cost Saving?

In one of the first jobs I did at ICI Plastics Division, I simulated a chemical process on an analogue computer. My mathematics showed they could use much smaller vessels, which meant the height of the plant could be reduced by a few  metres. I remember the engineer in charge of the project being very pleased, when he told me, that height costs money.

  • The reduced layout removes three bridges, which must mean a cost saving.
  • There is probably less track to lay

The negative is that digital signalling with ETCS must be installed through the area. This is going to be installed on the UK network, so it probably needs little more than shuffling the installation order.

On balance, when all things are considered, I suspect if the reduced layout can be used, there will be substantial cost savings on the project.

Problems At Morley Station

Morley station is two stations after Dewsbury station on the route towards Leeds.

Unusually for Wikipedia, the entry for Morley station has a large section entitled Current Problems.

This is the first two paragraphs.

The increase in demand, combined with growth elsewhere on the line, means that overcrowding in the morning peak, particularly for commuters heading towards Leeds, is becoming more of an issue.

Despite this commuter growth little has been done to bring this station into the 21st century. For example, only one platform is accessible for disabled passengers, there is insufficient parking, access routes to and from the station are often overgrown with weeds, and there are frequent drainage problems which all combine to make the station not as pleasant as other stations in West Yorkshire. In 2012 a “Friends of Morley station” group was formed, and is addressing some of these issues. Work to improve the car park and drainage commenced in February 2013.

To make matters worse, the station is 10-15 minutes walk from the centre of Morley with poor bus and taxi connections.

Would the following help the Friends of Morley Station?

  • Longer trains.
  • More frequent trains.
  • Faster trains to Leeds
  • Better bus services.

Electric trains would help solve the first three.

White Rose Station

There are plans to build a new White Rose station in the next couple of years at the White Rose Centre..

This would be between Morley and Cottingley stations.

This station will surely increase the passenger numbers on the Huddersfield Line.

Have Network Rail Designed The Electrification Between Dewsbury And Leeds?

This electrification has been off and on more times, than the lights in an average kitchen, so I suspect there is a workable plan dating from the last century amongst many others.

Would Extending Electrification To Leeds Provide The Power?

Electrification needs a good connection to the National Grid to provide the power needed to run the trains.

The short eight-mile electrification, as originally proposed could probably have been fed from one end; Huddersfield or Dewsbury.

Both locations would need new sub-stations, with Huddersfield possibly needed in the future to power the wires all the way to Manchester.

Leeds is already fully-electrified with electric expresses to Doncaster and London and several electric local services.

So is the easiest and most affordable way to power the eight-mile electrification between Huddersfield and Westtown to run an extension cable between Leeds and Dewsbury?

Network Rail had a similar problem on the Midland Main Line, which I wrote about in Welcome For Extension Of Midland Electrification.

National Grid had provided a power connection near Market Harborough for the Midland Main Line electrification, which was then cancelled North of Kettering North Junction, leaving the electrification to Corby without a power supply.

The problem is being solved, by extending the electrification to Market Harborough and connecting the wires to the power there.

I do wonder, that the most affordable way to power the Huddersfield and Westtown electrified line is to electrify all the way to Leeds and connect to the power there.

Conclusion

Improving services on the Huddersfield Line between Huddersfield and Leeds is going to be very necessary in the next few years, as passenger numbers will surely grow, due to new housing, increased commuting and the opening of White Rose station.

  • New or refurbished four-car electric trains would provide more capacity, increased frequencies and faster services,
  • Digital signalling with ETCS would allow more trains to run smoothly.

It appears to me, that to electrify all of the Huddersfield Line between Huddersfield and Leeds would be a good idea, if the money can be found.

Has that money been found by developing a more affordable track layout for the proposed TransPennine Upgrade between Huddersfield and Westtown?

But also using the power at Leeds and electrifying all the way between Huddersfield and Leeds, seems to be a bloody great tail, that is wagging the dog of electrification.

Further Electrification

Providing a fully-electrified route between Huddersfield and Leeds, would leave just two sections of the main TransPennine route without electrification.

I don’t know about the planning and difficulty of the first route, but from my helicopter the engineering shouldn’t be too difficult, with the exception of the elecxtrification of the Standedge Tunnels, although Wikipedia seems optimistic about the electrifying the main twin-bore tunnel.

During the 2000s, Network Rail proposed reinstating rail traffic through the 1848 and 1871 tunnels to increase capacity on the Leeds-Manchester trans-Pennine route, but after a re-appraisal after the decision to electrify the trans-Pennine line, it was reported in 2012 that reinstatement was unnecessary.

In addition, could it be, that Manchester with lots of electric trains can provide enough power at Stalybridge, where an updated power connection has been recently installed, to power electric trains between Manchester and Huddersfield?

, The second has been planned for years and has a string of advantages.

  • Speed up services between Leeds and Newcastle and Scotland.
  • Allow LNER to run electric trains between London and Scotland via Leeds.
  • Create an electrified route between Neville Hill Depot and York.
  • Create an electrified diversion through Leeds for the East Coast Main Line

This section should be electrified for operational reasons on the East Coast Main Line.

A Final Conclusion

Network Rail’s plans seem to have evolved under analysis to be as follows.

  • Limited four-tracking and updated track between Huddersfield and Westtown.
  • Digital signalling with ETCS between Huddersfield and Leeds.
  • Full electrification between Huddersfield and Leeds
  • Power for the electrification from Leeds.

Could it even cost less than the allocated £2.9billion?

Dewsbury Station

I broke my journey between Leeds and Huddersfield at Dewsbury station, where I had a very acceptable gluten-free pizza and a glass of cider.

I took these pictures of the station.

Note.

  1. There appears to be an avoiding line, through the station, which means that faster trains can pass slower ones stopped in the station.
  2. The station has a step-free bridge, but no toilets.
  3. The square outside the station has been recently landscaped.
  4. The station is Grade II Listed.
  5. The station has four TransPennine Express trains per hour (tph) in both directions.

Overall it is an excellent station with a touch of class, that probably deserves a few more trains.

Electrification

I cover possible electrification between Leeds and Huddersfield in Is There Going To Be Full Electrification Between Leeds And Huddersfield?.

Electrification as far as Leeds, which would offer faster acceleration and shorter station dwell times could offer the following.

  • The solution to the problems at Morley station. using longer and faster trains.
  • A faster journey time between Leeds and Huddersfield for the stopping trains.

Northern’s new Class 331 trains would probably do just fine.

If the stopping trains could run between Leeds and Huddersfield in perhaps twenty-five minutes, which may or may not be possible after the upgrade, just two trains would be needed for a two tph service.

I could see electrification opening up the following services on the electrified route, through Dewsbury.

  • Two tph – Leeds and Huddersfield – Stopping at all stations
  • One tph – Leeds and Wigan North Western – Stopping at all stations
  • Four tph – Leeds and Huddersfield – Stopping only at Dewsbury and other selected stations.

All except the Wigan service would be electric trains.

Conclusion

Dewsbury station is going to get a much-improved train service.

The Bridges At Mirfield

The tracks through Mirfield station are due to be upgraded as part of Network Rail’s £2.9billion project to upgrade the Huddersfield Linebetween Huddersfield and Dewsbury stations, that I wrote about in Network Rail Reveals Detailed £2.9bn Upgrade Plans For TransPennine Route.

This Google Map shows the railway bridges, a road bridge and the surrounding land.

These pictures show the bridges.

The bridge is in two parts and the original stone bridge is Grade II Listed. The entry on Historic England contains this description of the bridge.

Railway bridge. Circa 1840. Engineer George Stephenson, supervisor T. L. Gooch, for the Manchester and Leeds Railway. Rock-faced stone with rusticated dressings. Four segmental arches over river and a further five arches to west and two to east, all on bull-nosed abutments. String course at base of stone parapet. Later steel bridge on south side, not included in the item.

I suspect that it will be needed to be treated very sensitively, because of the age, the Listed status and the builder.

I also feel, that any work won’t be easy, due to the restricted site and the River Calder underneath.

I feel that the most likely track layout through Mirfield station will be the reduced four-track layout, that I found in this document on the Digital Railway web site is entitled Transpennine Route Upgrade SDO1 ETCS – Analysis.

Note.

  1. There are four tracks between Mirfield station and Heaton Junction, where trains go South-West towards Deighton and Huddersfield.
  2. The older stone bridge would appear to be carrying the slow trains and those going between Brighouse and Wakefielld.
  3. The steel bridge on the South side would appear to be carrying the fast trains.

It looks to me, that the track layout has been designed, so that the steel bridge can be replaced if required, without too much disruption.

The Weight Limit Of The Existing Bridges

TransPennine Express have bought a series of trains, that will be running over the existing bridges.

So they can’t be that weak!

Electrification

Electrification could be a problem on the older stone bridge, as it is the sort of project like the Steventon Bridge, that the Heritage Lobby like to attack!

Upgrading Mirfield Station

Mirfield station is due to be upgraded as part of Network Rail’s £2.9billion project to upgrade the Huddersfield Line between Huddersfield and Dewsbury stations, that I wrote about in Network Rail Reveals Detailed £2.9bn Upgrade Plans For TransPennine Route.

This Google Map shows the station and the surrounding land.

These pictures show the station.

Currently, it is a three-station platform, with a wide island Platform 1/2 and a separate platform 3. The platforms are used as follows.

  • Platform 1 for all Eastbound trains.
  • Platform 2 for Westbound through trains.
  • Platform 3 for Westbound stopping trains.

This document on the Digital Railway web site is entitled Transpennine Route Upgrade SDO1 ETCS – Analysis.

It is mainly about using digital signalling called ETCS on the Transpennine Route, but it does give these track layouts between Huddersfield and Dewsbury.

This is the current layout.

This is a reduced four-track layout.

In Proposed Track Layouts Between Huddersfield And Dewsbury, I came to the conclusion, that the reduced four-track layout or something better could handle the current trains through the area.

If the reduced four-track layout is used, the requirements for a new Mirfield station can now be stated.

  • Platforms 1/2 sharing an island on the slow tracks.
  • Platforms 3/4 sharing an island on the fast tracks.
  • Some better shelters than at present.
  • Step-free footbridges or a tunnel

In Winner Announced In The Network Rail Footbridge Design Ideas Competition, I wrote how the competition was won by this bridge.

So could a factory-built bridge like this be installed at Mirfield station?

  • There is plenty of space.
  • The bridge would have the correct clearance for the electrification.

It could also replace the subway to Platform 1/2.

Upgrading Ravensthorpe Station

Ravensthorpe station is due to be upgraded as part of Network Rail’s £2.9billion project to upgrade the Huddersfield Line between Huddersfield and Dewsbury stations, that I wrote about in Network Rail Reveals Detailed £2.9bn Upgrade Plans For TransPennine Route.

This Google Map shows the station and the surrounding land.

Note.

  1. The lines through the station go between Huddersfield in the East and Dewsbury in the North-East.
  2. The line going East goes to Wakefield.

These pictures show the station.

I did try to get a picture of the bridges over the River Calder, but I was unable to find the route and the weather was about to deteriorate.

The station is currently just two platforms on the lines between Huddersfield and Dewsbury, with a terrible overbridge, a poor shelter and a couple of seats.

The Wikipedia entry for Ravensthorpe station says this.

Ravensthorpe station is adjacent to Thornhill LNW (London North Western) Junction, where a line branches to Wakefield Kirkgate. There are plans to extend the station by building new platforms on this line, which was built by the former Manchester and Leeds Railway.

This document on the Digital Railway web site is entitled Transpennine Route Upgrade SDO1 ETCS – Analysis.

It is mainly about using digital signalling called ETCS on the Transpennine Route, but it does give these track layouts between Huddersfield and Dewsbury.

This is the current layout.

This is a reduced four-track layout.

In Proposed Track Layouts Between Huddersfield And Dewsbury, I came to the conclusion, that the reduced four-track layout or something better could handle the current trains through the area.

If the reduced four-track layout is used, the requirements for a new Ravensthorpe station can now be stated.

  • Two platforms on the tracks to and from Dewsbury.
  • Two platforms on the tracks to and from Wakefield.
  • Some better shelters than at present.
  • Step-free footbridges.

In Winner Announced In The Network Rail Footbridge Design Ideas Competition, I wrote how the competition was won by this bridge.

So could a factory-built bridge like this be installed at Ravensthorpe station?

  • The platforms from Dewsbury and to Wakefield, could probably be arranged as a walk-across interchange.
  • This would mean that the flexible nature of the bridge design would enable a single bridge with three lifts and three sets of stairs to be erected to join all the platforms together.
  • The bridge would have the correct clearance for the electrification.

I doubt it would be the most complicated of stations.

Proposed Track Layouts Between Huddersfield And Dewsbury

Tracks between Huddersfield and Dewsbury stations are due to be upgraded as part of Network Rail’s £2.9billion project to upgrade the Huddersfield Line between the two stations, that I wrote about in Network Rail Reveals Detailed £2.9bn Upgrade Plans For TransPennine Route.

  • Slow trains from Dewsbury to Huddersfield will use the centre track from East to West and call in/pass Platform 2 at Mirfield station before turning South-West  on to Huddersfield. This is as trains do now.
  • Fast trains from Huddersfield to Dewsbury will call in/pass Platform 3 at Mirfield station and then cross over to the top track and go straight on to Ravensthorpe and Dewsbury.
  • Fast trains from Dewsbury to Huddersfield will use the centre track from East to West and call in/pass Platform 4 at Mirfield station before turning South-West  on to Huddersfield.
  • Trains from Brighouse  to Wakefield will call in/pass Platform 1 at Mirfield station and then cross to the centre track and go straight on to Wakefield. This is as trains do now.
  • Trains from Wakefield to Brighouse will use the centre track from East to West and call in/pass Platform 2 at Mirfield station and go straight on to Brighouse.

Note.

  1. Platforms at Mirfield station are numbered 1 to 4 from the North
  2. The slow lines between Mirfield and Huddersfield are shown in black.
  3. The fast lines between Mirfield and Huddersfield are shown in blue.
  4. Passengers can use Platforms 1/2 as a cross-platform interchange between slow Huddersfield-Leeds and Brighouse-Wakefield services.

I also think it likely, that the proposed layout will improve the timetable.

Conclusion

I think it is highly likely that the reduced four-track layout will be used.

Unless of course something better is devised.

Network Rail Reveals Detailed £2.9bn Upgrade Plans For TransPennine Route

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

It is planned to be a comprehensive upgrade to the Huddersfield Line that includes.

  • Improvement between Huddersfield and Westtown
  • Grade separation or a tunnel at Ravensthorpe
  • Rebuilding and electrification of eight miles of track.
  • Possible doubling the number of tracks from two to four.
  • Improved stations at Huddersfield, Deighton, Mirfield and Ravensthorpe.

This project should be a major improvement to the Huddersfield Line.

Here are my thoughts on the upgrade.

Where Is Westtown?

Westtown is a difficult place to find on Google Maps.

This Google Map is the best I can do.

Note that Dewsbury station is at the North-East of the map and Ravensthorpe station is in the South-West corner, with the Huddersfield Line going through both stations.

  • To the South-West the line goes to Mirfield, Deighton and Huddersfield.
  • To the North-East the line goes to Batley, Morley, Cottingley and Leeds.

Westtown can be seen indicated to the West of the Huddersfield Line, North of the River Calder.

Railways Between Dewsbury And Huddersfield

This map clipped from the Wikipedia entry for the Huddersfield Line, shows the route between Dewsbury and Huddersfield stations.

Note the Leeds New Line, which was built by the London and North Eastern Railway and opened in 1900.

It appears to have been closed between 1960 and 1990.

Everybody blames Beeching for the closure of railways, but this closure started before he reported.

But it does seem, that LNER decided that four tracks were needed between Leeds and Huddersfield and that British Railways felt that two was enough.

It now appears that part of the solution to increasing capacity is to create a four-track section of the Huddersfield Line between Huddersfield and Westtown.

We often blame the state of our railways on poor Victorian planning and engineering, but it does appear that they got it right here and British Rail got it wrong, in the 1960s.

A Very Busy Line

If you look at the traffic through Dewsbury station, it is a busy train-spotters paradise, with five scheduled trains per hour (tph) typically stopping at the station and several more passing through.

Four-Tracking Between Huddersfield And Westtown

This is Network Rail’s preferred solution to providing more capacity between Huddersfield and Desbury.

It is not going to be simple engineering all the way.

This Google Map shows the Huddersfield Line crossing the River Calder and the Calder and Hebble Navigation Canal South of Dewsbury station and to the North of Ravensthorpe station.

Note the two double-track bridges over the waterways.

This page on Georgraph has a picture of the bridge over the River Calder. It looks an excellent example of a Victorian wrought iron bridge.

Depending on their condition, these might need to be replaced, but they will certainly need to be upgraded to four tracks.

This Google Map shows Ravensthorpe station and the rail lines in the area in more detail.

The line going East from Ravensthorpe goes to Wakefield Kirkgate station, although there are no platforms at Ravensthorpe.

The Wikipedia entry for Ravensthorpe station says this.

Ravensthorpe station is adjacent to Thornhill LNW (London North Western) Junction, where a line branches to Wakefield Kirkgate. There are plans to extend the station by building new platforms on this line, which was built by the former Manchester and Leeds Railway.

It looks to me that there are possibilities to rebuild Ravensthorpe station and the lines in the area to meet the following objectives.

  • Two fast lines and two slow lines through the station.
  • Platforms for Dewbury and Leeds services.
  • Platforms for Wakefield Kirkgate services.
  • Four tracks to as close to Dewsbury station as possible.

It must help that a lot of the land North of the line to Wakefield Kirkgate, appears to be devoid of buildings.

The engineering would not be difficult, but probably extensive and expensive.

It should be noted that the Werrington Diver Under near Peterborough, which is a similar scale of project, was costed at £200 million.

West of Ravensthorpe station, there appears to be plenty of space to fit in two extra tracks alongside the current pair.

This Google Map shows Ravensthorpe station and the tracks to the West.

Note that there is space on both sides of the current tracks and a bridge.

But between Ravensthorpe and Mirfield stations, there are at least three more bridges.

This Google Map shows Mirfield station and the tracks to the West.

There could be problems adding extra tracks here.

  • The track and platform layout is unusual.
  • There may be a lack of space at the station.

But the biggest problem will probably be four-tracking the bridge over the River Calder.

This Google Map shows the bridge in more detail.

It does appear that the bridge currently has three tracks and might have at some time had four tracks.

If the two extra tracks could be added to this bridge, it would probably be heroic engineering at a high cost, given the difficulty of the site.

But I think engineers have replaced similar bridges on UK railways in recent years.

After Mirfield, the tracks take a wide loop to the North to go to Deighton station.

The tracks were probably built to follow the contours above the River Calder, so hopefully despite the terrain, they could be fairly level.

This Google Map shows the tracks through Deighton station.

It certainly looks that there should be room for two extra tracks.

Between Deighton and Huddersfield stations, it would appear that four-tracking would be as easy as any part of the route.

Looking at the stations from the air from my helicopter (i.e. Google Maps), I suspect that one way to four-track the line would be to proceed in something like this way.

  • Rebuild and four-track the bridge over the River Calder at Mirfield station.
  • Build the junction and the bridges to the North-East of Ravensthorpe station.
  • Create a pair of fast lines on the South side of the current tracks.
  • Move all traffic onto these new fast lines.
  • Rebuild the existing railway and the stations.

There may be a need for replacement buses, whilst the stations are rebuilt, but hopefully through services could continue.

Electrification

The Rail Technology Magazine opens with this paragraph.

Major station upgrades and plans to rebuild and electrify an 8-mile stretch of track have been put forward by Network Rail as part of a public consultation on a major upgrade to the TransPennine route.

As it is eight miles between Huddersfield and Dewsbury stations, it would seem likely that the electrification will stretch between the two stations.

This would enable TransPennine Express’s Class 802 trains to switch between electric and diesel power in the stations, if this is preferred by the operator.

Line Speed

The eight miles section of track will never have a particularly high speed, given the not very straight route and the terrain.

Currently, trains that stop at both Huddersfield and Dewsbury stations take eight minutes for the trip. Even trains going at speed through both stations seem no faster.

Four-tracking will surely allow fast expresses to pass local services and freight trains, but will the improvement save much time?

If trains could average 100 mph between Huddersfield and Dewsbury, just over three minutes could be saved.

Station Upgrades

The three stations between Huddersfield and Dewbury will all be upgraded, as will Hudderfield station.

The three smaller stations will probably be rebuilt as four platform stations or two platform stations with two through lines for fast services.

In Huddersfield And High Speed Two, I showed several pictures of Huddersfield station.

  • It will not be easy to upgrade to a full four-track station.
  • There are three through tracks and some bay platforms.

The two main through platforms are on the South side of the station, so if the two fast lines were on the South side of the route between Huddersfield and Ravensthorpe, this could enable an efficient station at Huddersfield.

I also think, there could be a problem at Huddersfield station, with trains to Sheffield on the Penistone Line, if more and faster trains were going through the station.

A New Timetable

I suspect that, if and when the upgrade is finished, that a new timetable will be brought in.

A possibility could be. that TransPennine Express trains run non-stop between Huddersfield and Leeds.

Now that Northern are getting new trains, perhaps these could run a Turn-Up-And-Go service of a train every fifteen minutes between Huddersfield and Leeds.

Heritage Issues

Huddersfield station is a Grade I Listed building and I suspect that the three bridges I have noted are lListed as well.

Will the Heritage lobby object to electrification in these sensitive areas?

Onward To Manchester

I have flown my helicopter between Huddersfield and Stalybridge and if the proposed improvement is successful, I suspect that the route to the West can be improved as far as Stalybridge.

  • The route is at least double track.
  • It looks like in places, it once had more tracks.
  • The trackside margins are fairly generous.
  • There doesn’t seem to be too many bridges.
  • Electrification will soon be as far as Stalybridge from Manchester.

After my quick look, I don’t think that electrifying between Huddersfield and Manchester would be too challenging, except for possibly, the Standedge Tunnel.

Onward To Leeds

The route between Dewsbury and Leeds is double track, with the only complication of the Morley Tunnel.

Conclusion

It looks to me, that all the difficult bits to creation of an electrified route between Manchester and Leeds via the Huddersfield Line, are in the stretch between Huddersfield and Dewsbury.

So perhaps it makes sense to sort out the difficult bits first, with this £2.9billion project.

Thoughts On A Battery Electric Class 88 Locomotive On TransPennine Routes

In Issue 864 of Rail Magazine, there is an article, which is entitled Johnson Targets A Bi-Mode Future.

As someone, who has examined the mathematics of battery-powered trains for several years, I wonder if the Age of the Hybrid Battery/Electric Locomotive is closer than we think.

A Battery/Electric Class 88 Locomotive

 After reading Dual Mode Delight (RM Issue 863), it would appear that a Class 88 locomotive is a powerful and reliable locomotive.

  • It is a Bo-Bo locomotive with a weight of 86.1 tonnes and an axle load of 21.5 tonnes.
  • It has a rating on electricity of 4,000 kW.
  • It is a genuine 100 mph locomotive when working from 25 KVAC overhead electrification.
  • The locomotive has regenerative braking, when working using electrification.
  • It would appear the weight of the diesel engine is around seven tonnes
  • The closely-related Class 68 locomotive has a 5,600 litre fuel tank and full of diesel would weight nearly five tonnes.

It is worth looking at the kinetic energy of a Class 88 locomotive hauling five forty-three tonne CAF Mark 5A coaches containing a full load of 340 passengers, who each weigh 90 Kg with baggage, bikes and buggies. This gives a total weight would be 331.7 tonnes.

The kinetic energy of the train would be as follows for various speeds.

  • 90 mph – 75 kWh
  • 100 mph – 92 kWh
  • 110 mph – 111 kWh
  • 125 mph – 144 kWh

The increase in energy is because kinetic energy is proportional to the square of the speed.

Supposing the seven tonne diesel engine of the Class 88 locomotive were to be replaced by a battery of a similar total weight.

Traction batteries seem to have an energy/weight ratio of about 0.1kWh/Kg, which is increasing with time, as battery technology improves.

A crude estimate based on this energy/weight ratio would mean that at least a 700 kWh battery could be fitted into a Class 88 train and not make the locomotive any heavier. Given that lots of equipment like the alternator and the fuel tank would not be needed, I suspect that a 1,000 kWh battery could be fitted into a Class 88 locomotive, provided it just wasn’t too big.

A short length of electrification could be installed at terminal stations without electrification to charge the batteries during turnround.

This size of battery would be more than large enough to handle the braking energy of the train from full speed, so would improve the energy efficiency of the train on both electrified and non-electrified lines.

It would also contain more than enough energy to accelerate the train to line speeds that are typical of non-electrified routes.

TransPennine Express will soon run similar rakes of coaches hauled by Class 68 diesel locomotives between Liverpool and Manchester Airport and the North East.

The following sections of the Northern TransPennine route, are not electrified.

  • Stalybridge and Leeds – 35 miles taking 46 minutes
  • Leeds and Colton Junction – 20 miles taking 18 minutes
  • Northallerton and Middlesbrough – 21 miles taking 29 minutes
  • York and Scarborough – 42 miles taking 56 minutes

When running on these sections without electrification, consider the following.

  • The train consists of modern coaches, which must be energy efficient.
  • The train would enter the sections with a full battery, that had been charged using the 25 KVAC electrification on part of the route.
  • Scarborough and possibly Middlesbrough stations, would have means to charge the battery.
  • The train would enter the sections as close to line speed as possible, after accelerating using electrification.
  • Regenerative braking would help conserve energy at any planned or unplanned stops.
  • The driver will be assisted by a modern in-cab signaling and a very capable Driver Assistance System.
  • Stadler and Direct Rail Services must have extensive theoretical and measured data of the performance of Class 88 locomotives and the related Class 68 locomotive, when they are hauling trains across the Pennines, which will enable extensive mathematical models to be built of the route.

For these reasons and especially the last about mathematical modelling, I believe that Stadler could create a battery/electric locomotive based on the Class 88 locomotive, that would be able to bridge the electrification gaps on battery power and haul a five-coach train on the Northern routes across the Pennines.

A Quick Look At The Mathematics

As I said earlier, the weight of a Class 88 locomotive and five Mark 5A coaches, full of passengers is 331.7 tonnes.

There would appear to be little weight difference between a diesel Class 68 locomotive and an electro-diesel Class 88 locomotive, so in this rough exercise, I will assume the train weight is the same.

The current Class 185 trains, that run across the Pennines have the following characteristics.

  • Three-cars
  • A weight of 168.5 tonnes.
  • A passenger capacity of 169.
  • Installed power of 560 kW in each coach, which means there is 1560 kW in total.

If each passengers weighs 90 Kg, with all their extras, a full train will weigh 183.7 tonnes.

So a full train has a power-weight ratio of nine kW/tonne, which must be sufficient to maintain the timetable across the Pennines.

The diesel Class 68 locomotive, which will be hauling trains on the route in the New Year,  has an installed power of 2,800 kW, which gives a power/weight ratio of 8.4 kW/tonne.

I would be interested to know, if a Class 88 locomotive running in diesel mode with a power output of only 700 kW, could take one of the new trains across the Pennines. I suspect Stadler and/or DRS know the answer to this question.

But it would be a power/weight ratio of only 2.1 kW/tonne!

The challenging route is between Stalybridge and Leeds via Huddersfield, where the Pennines has to be crossed. I’m pretty certain, that all the other sections lack the gradients of the section between Stalybridge and Leeds.

So would a Class 88 locomotive with a 1,000 kWh battery be able to cross the Pennines with a full train?

Theoretically, up and down routes are good for battery/electric trains with regenerative braking, as energy used going uphill can be recovered on the other side.

The thirty-five miles between Stalybridge and Leeds take forty-six minutes, so for how long on this journey will the locomotive be applying full power? Perhaps for twenty minutes. If the locomotive applied an average of 2,000 kW for twenty minutes or a third of an hour, that would be 667 kWh.

With an electric multiple unit like an Aventra, where most if not all axles are driven and they can also contribute to regenerative braking, reasonably high rates of braking energy can be recycled.

But what proportion can be recycled, when the locomotive is doing all the regenerative braking. Any braking done by disc brakes on the coaches will result in lost energy.

As an aside, I wouldn’t be surprised to find out that train manufacturers simulate train braking in order to develop braking systems, that turn less energy into wasted heat.

I’d also love to see a simulation using Stadler’s real data of a Class 88 locomotive with batteries attempting to cross the Pennines, with a rake of Mark 5A coaches!

  • What size of battery will be needed?
  • Can this battery be fitted in the locomotive?
  • Would distributing the batteries along the train increase performance?
  • Would short lengths of electrification on the route, increase performance?

I was doing problems of similar complexity to attempt to design efficient chemical plants nearly fifty years ago. We had our successes, but not as great as we hoped. But we certainly eliminated several blind alleys.

My figures don’t show conclusively, that a Class 88 locomotive with a 1,000 kWh battery instead of a diesel engine and all the related gubbings, would be able to perform services across the Pennines.

But.

  • Battery technology is improving at a fast pace.
  • Train manufacturers are finding surprising ways to use batteries to improve performance.
  • I don’t have access to Stadler’s real performance figures of their diesel locomotives.
  • Finding a way to make it work, has a very high cost benefit.

Who knows what will happen?

125 Mph Running

The Class 88 locomotive, has a similar power output to the 125 mph Class 91 locomotive of the InterCity 225 and I believe that the locomotive might have enough power, when running on 25 KVAC overhead wires to be able to haul the train at 125 mph on the East Coast Main Line.

Conclusion

I believe that it is possible to create a battery/electric version of the Class 88 locomotive, that should be able to take a rake of five Mark 5A coaches across the Pennines.

Timings across the Pennines would benefit substantially, without any new infrastructure, other than that already planned and the charging system at Scarborough.
