The Anonymous Widower

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.

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.

The Future Of TransPennine Express

TransPennine Express operates services across the Pennines.

In Changes Signalled For HS2 Route In North, I explored the possibilities of merging the infrastructure of High Seed Two and Northern Powerhouse Rail, as proposed by this report on the Transport for the North web site, which is entitled At A Glance – Northern Powerhouse Rail.

In my post, I proposed this service pattern across the Pennines, after sketching it on one of the 5 x 3 inch cards, that I use for notes.

  • High Speed Two – Two tph between London and Hull via Manchester Airport, Manchester Piccadilly and Leeds
  • High Speed Two – One tph between London and Edinburgh via Manchester Airport, Manchester Piccadilly, Leeds, York and Newcastle.
  • Northern Powerhouse Rail – One tph between Liverpool and Edinburgh via Manchester Airport, Manchester Piccadilly, Leeds, York and Newcastle.
  • Northern Powerhouse Rail – Two tph between Liverpool and Sheffield via Manchester Airport and Manchester Piccadilly
  • Northern Powerhouse Rail – Two tph between Liverpool and Hull via Manchester Airport, Manchester Piccadilly and Leeds
  • Northern Powerhouse Rail – One tph between Liverpool and Sunderland via Manchester Airport, Manchester Piccadilly, Leeds, York and Middlesbrough.

But how do proposed services across the Pennines like these, fit with the current TransPennine Express services?

Manchester Airport And Middlesbrough

The Liverpool and Sunderland service covers the same route. at the same frequency of one tph.

Manchester Airport And Newcastle

The London and Edinburgh and Liverpool and Edinburgh services cover the same route, at a doubled frequency of two tph.

Liverpool And Newcastle

The Liverpool and Edinburgh service covers the same route, at the same frequency of one tph.

Liverpool And Scarborough

I didn’t put this in thew original proposed schedule, so it would need to be added at one tph.

Manchester Piccadilly And Hull

The London and Hull and Liverpool and Hull services cover the same route, at an increased frequency of four tph.

Manchester Piccadilly And Huddersfield And Huddersfield And Leeds

These two services, either side of Huddersfield, are effectively local services and could either stay with TransPennine Express or be moved to Northern.

Manchester Airport And Cleethorpes

The Liverpool and Sheffield service covers the same route, at a doubled frequency of two tph, as far as Sheffield.

One tph could be extended to |Cleethorpes.

Manchester Airport And Glasgow Central

If there is a connection between the Northbound West Coast Main Line and Westbound Northern Powerhouse Rail then this service will be possible at the current frequency of one tph.

There would need to be a West-facing terminating platform at Manchester Airport.

Alternatively, this could remain a Classic service.

Manchester Airport and Edinburgh

The London and Edinburgh and Liverpool and Edinburgh services cover the same route, at a doubled frequency of two tph.

Liverpool And Glasgow Central

If there is a connection between the Northbound West Coast Main Line and Eastbound Northern Powerhouse Rail then this service will be possible at the soon-to-be-introduced frequency of one tph.

It could use Liverpool’s High Speed station.

Alternatively, this could remain a Classic service.

New Services

I could also throw in a few other services.

Liverpool And Nottingham

Could a service between Liverpool’s new High Speed station and Nottingham be introduced with a frequency of one tph?

The route would be via Manchester Airport, Manchester Piccadilly and Sheffield on Northern Powerhouse Rail before reversing at Sheffield and travelling to Nottingham via Chesterfield and Alfreton.

Scarborough And Llandudno

Why not?

If the demand is there various services might be viable.

Extra Stations

I think we will also see more station calls, by both High Speed and TransPennine Express trains.

Conclusion

TransPennine Express will be a very different franchise in the future.

Puzzled By New Fleets For TransPennine Express

TransPennine Express (TPE) are replacing all their trains, but their choice of three different new fleets puzzles me.

The new fleets and their routes are as follows.

Nova1

This is a fleet of nineteen five-car bi-mode Class 802 trains.

According to Wikipedia, they will work the following routes, with probably a frequency of one tph

Liverpool Lime Street and Edinburgh via Newcastle, which I estimate will take 4:15 hours

Manchester Airport and Newcastle, which takes around 2:45 hours

These two services would probably need nine for the Edinburgh service and six for the Manchester Airport service.

This means that there are four extra trains.

If there is a spare or one in maintenance, that means that two trains are available to boost capacity on busy services if needed, by running a ten-car train.

I doubt that ten-car services to Manchester Airport could be run through the Castlefield Corridor due to the inadequate stations, but Liverpool and Edinburgh might be a route for longer trains.

I have some observations on Nova1.

  • The trains are 125 mph trains, that can be upgraded to 140 mph with in-cab signalling.
  • The trains will share the East Coast Main Line with LNER’s Azumas, which are other members of te same family of Hitachi trains.

The trains have been authorised to start running services.

Nova2

This is a fleet of twelve electric Class 397 trains.

According to Wikipedia, they will work the following routes,

  • Manchester Airport and Glasgow Central, which takes around 3:30 hours.
  • Manchester Airport and Edinburgh, which takes around 3:15 hours.
  • New route – Liverpool Lime Street and Glasgow Central, which could take around 3:30 hours.

Currently, the two existing routes run at a frequency of one train per two hours, which would probably need at least seven trains.

This probably means that there will be four trains left for the service between Liverpool and Glasgow, if it assumed there is one train spare or in maintenance.

As a round trip between the two cities, would probably take eight hours, it looks like the frequency will be one train per two hours.

This would give the following services, all with a frequency of one train per two hours.

  • Manchester Airport and Glasgow Central via Manchester Piccadilly
  • Manchester Airport and Edinburgh via Manchester Piccadilly
  • Liverpool Lime Street and Glasgow Central

Passengers wanting to go between Liverpool Lime Street and Edinburgh should keep reading.

I have some observations on Nova2.

  • They are 125 mph trains that are replacing the 110 mph Class 350 trains.
  • In the next few years, these 125 mph trains will be sharing the West Coast Main Line with faster trains like Class 390 trains and the trains of High Speed Two, both of which should be capable of 140 mph, when running using in-cab signalling.
  • I would assume that the trains can be similarly upgraded, otherwise they will have to be replaced.
  • There was an option for more trains, but I suspect the success of Class 802 trains on the Great Western Railway led to it not being taken up.,

The trains should come into service later this year.

Nova3

This is a fleet of five-car rakes of Mark 5A coaches, hauled by a Class 68 diesel locomotive.

There are fourteen locomotives and driving van trailers, with enough coaches for thirteen rakes.

I would suspect that TPE are aiming to have twelve trains available for service.

According to Wikipedia, they will work the following routes, which both have a frequency of one train per hour (tph)

  • Liverpool Lime Street and Scarborough via Manchester Victoria, which takes around 2:45 hours.
  • Manchester Airport and Middlesbrough, which takes around 2:45 hours.

So with turnround at both ends, I suspect that a six hour round trip is possible. So to provide the two hourly services across the Pennines, TPE will need six trains for each route.

This explains a fleet size of twelve operational trains.

I have two observations on Nova3.

  • They are diesel-powered and will be running at times on electrified lines. But I suspect the diesel Class 68 locomotive could be replaced in the future with an electro-diesel Class 88 locomotive.
  • Questions have been raised about the speed of exit and entry from the coaches through single end doors of the coaches.
  • They have an operating speed of only 100 mph, but opportunities for higher speeds on the routes are limited to perhaps thirty to forty miles on the East Coast Main Line.

At least they should be in service within a couple of months.

Why Didn’t TPE Order A Unified Fleet?

To summarise TPE have ordered the following trains.

  • Nova1 – Nineteen Class 802 trains
  • Nova2 – Twelve Class 397 trains.
  • Nova3 – Thirteen trains consisting of four coaches topped and tailed by a a Class 68 locomotive and driving van trailer.

All forty-four trains are five cars.

Surely, it would have been easier for TPE to have a fleet, where all the trains were the same.

I suspect that all routes can be run using Class 802 trains, so it as not as if there are any special requirements for the trains.

So why didn’t TPE order a fleet of Class 802 trains?

I can only think of these reasons.

  • Hitachi couldn’t supply the required number of trains in the appropriate time-scale.
  • ,CAF made an offer that TPE couldn’t refuse.

It should also be born in mind that Great Western Railway and Hull Trains, which like TPE are  First Group companies, went down the Class 802 route.

The Future

There are various issues, that will arise in the future.

Nova2 And West Coast Main Line Operating Speed

The new Nova trains are running on TPE’s Northern and Scottish routes and as I indicated earlier, the Nova2 trains might not be fast enough in a few years time for the West Coast Main Line, which will have Class 390 trains running at 140 mph using in-cab signalling.

High Speed Two will surely make this incompatibility worse, unless CAF can upgrade the Nova2 trains for 140 mph running.

Replacing the Nova2 trains with Class 802 trains, which are being built for 140 mph running, would solve the problem.

Nova3 And Class 68 Locomotives

There are powerful reasons to replace diesel locomotives on the UK’s railways, with noise, pollution and carbon emissions at the top of the list.

As Northern Powerhouse Rail is created, there will be more electrification between Manchester and York, adding to the pressure to change the traction.

  • There could be a change of locomotives to Class 88 or Class 93 locomotives, which would run using the overhead electrification, where it exists.
  • The trains could be changed to Class 802 trains.

The Class 68 locomotive is increasingly looking like an interim solution. At least, it’s a less polluting locomotive, than the dreaded and ubiquitous Class 66 locomotive.

Class 185 Replacement

TPE will still have a fleet of diesel three-car Class 185 trains.

  • They are running on routes between Manchester and Hull and Cleethorpes via Huddersfield, Leeds and Sheffield.
  • These are best described as just-about-adequate trains and are one of The Treasury’s boob-buys.
  • As Northern Powerhouse Rail is created, they will be increasingly running under wires.
  • Could it be likely that more capacity will be needed on routes run by these trains?
  • The capacity of a Class 185 train is 169 seats, as opposed to the 342 seats of a five-car Class 802 train.

I think it could be very likely that instead of running pairs of Class 185 trains, TPE will replace them with five-car Class 802 trains.

Conclusion

I very much feel, that over the next few years, TPE’s fleet will change further in the direction of a one-unified fleet!

Grayling: No Solution To Oxford Road Woes

The title of this post, is the same as that of this article on Place North West.

This is the first two paragraphs.

Transport Secretary Chris Grayling has said there is no “simple, quick, non-disruptive solution” to improving journeys on one of the most congested rail routes in and out of Manchester, arguing the cost of the original scheme was “way out of kilter”.

Plans to extend platforms at Oxford Road station have been mooted for a number of years, and were designed to take advantage of the completion of the Ordsall Chord to allow more frequent trains between Piccadilly, Victoria, and beyond.

The more I read about the problems of the Castlefield corridor through Manchester, the more I’m coming to the conclusion, that British Rail’s three tunnel scheme for the North was the right solution.

Liverpool

Liverpool got the Loop And Link Project, which is described like this in Wikipedia.

The major engineering works required to integrate the Northern and Wirral lines became known as the ‘Loop’ and ‘Link’ Project. The ‘Loop’ was the Wirral Line tunnel and the ‘Link’ the Northern Line tunnel, both under Liverpool’s city centre. The main works were undertaken between 1972 and 1977. A further project, known as the Edge Hill Spur, would have integrated the City Lines into the city centre underground network. This would have meshed the eastern section of the city into the core underground electric city centre section of the network, releasing platforms at mainline Lime Street station for mid to long haul routes.

The Edge Hill Spur was never built and if it had, it may have created the extra capacity, that Liverpool Lime Street station has now finally got, but several years ago.

Liverpool’s Underground railways are getting a new fleet of Class 777 trains and will be expanded in the next few years.

British Rail’s scheme for Liverpool has been successful.

Although, I am surprised that the layout of a single-track loop tunnel, that is used to terminate the Wirral Line, has not been copied more.

Newcastle

Newcastle got tunnels under the city, to join up the Tyne and Wear Metro in the late 1970s.

The Metro is now getting a new fleet of trains and will be further expanded.

British Rail’s scheme for Newcastle has been successful.

Manchester

Manchester had a scheme in the pipeline called the Picc-Vic Tunnel.

This Proposal section in Wikipedia gives a full description of the project. This is the first paragraph.

The South-East Lancashire and North-East Cheshire Public Transport Executive (SELNEC PTE) – the local transport authority which became the Greater Manchester Passenger Transport Executive (GMPTE) in 1974 (now Transport for Greater Manchester – TfGM) – made a proposal in 1971 to connect the unjoined railways running through Manchester city centre under the Picc-Vic scheme. The Picc-Vic proposal envisaged joining the two halves of the rail network by constructing new tunnels under the city centre, connecting Manchester’s two main railway stations, Piccadilly and Victoria. This new underground railway would be served by three new underground stations, joining together the regional, national and local rail networks with an underground rapid transit system for Manchester.

It also gives these three objectives for the scheme.

  • To improve the distribution arrangements from the existing railway stations which are on the periphery of the central core
  • To link the separated northern and southern railway systems
  • To improve passenger movement within the central area.

This is also said.

It formed part of a four-phase, Long Term Strategy for GMPTE over 25 years, which included bus priority and an East-West railway network, as well as a light rapid transport system.

The scheme was cancelled by Harold Wilson’s government, partly because he believed that railways were of the past and that everybody would be able to afford their own car and wouldn’t need to use trains.

It should also be remembered that his government also cancelled the Channel Tunnel and London’s Third Airport at Maplin.

It’s funny, but I thought, I’d used the Channel Tunnel several times. Perhaps, Harold Wilson didn’t get his out-of-kilter thinking sufficiently into the minds of Civil Servants. Although, there is still the Treasury’s periodic attempts to kill High Speed Two. But that is driven by the belief of the average Oxford graduate, that there is nothing worth visiting North of Watford.

The Picc-Vic Tunnel may not have completely solved Manchester’s rail connectivity, but it is my belief that it would have been a good start.

A Few Random Thoughts

These are a few random thoughts on the various schemes in Manchester.

Development of Piccadilly And Victoria After A Picc-Vic Tunnel

One of the reasons for cancellation, was that after the building of the tunnel, two large stations would still be maintained in the City.

Looking at various schemes across Europe including Kassel and Leipzig in Germany, where central tunnels have been built, this releases the terminals for development with smaller numbers of platforms.

I think if the Picc-Vic Tunnel had been built, then Piccadilly and Victoria might have morphed into combined through and terminal station like the excellent London Bridge. The released space at Piccadilly would have allowed High Speed Two to be integrated.

But of course, the elite in the Civil Service isn’t interested in High Speed Trains, except on their holidays in France.

TransPennines New Trains

Greater Anglia needed to have new rolling stock for services between London and Norwich.

They needed trains with following.

  1. 100 mph running
  2. Eight coaches
  3. Powerful traction
  4. Short station dwell times.
  5. High quality.

So they ordered a fleet of new Class 745 trains.

  • 100 mph running
  • Twelve coaches
  • Walk-through trains
  • 757 seats
  • Double doors for easy entry and exit.

It’s also rumoured that platform height will be adjusted so that that buggy-pushers and wheelchair-users will have level access between train and platform at all stations.

  • If you want to do Norwich-in-90 for all trains, then a short station dwell time is essential.
  • It also means if passenger numbers need another station to be added to a route, the extra stop only blows a small hole in the schedule, as opposed to a large one for a train of Mark 3 coaches.
  • I have a feeling Greater Anglia are aiming to send all their disabled ramps to the scrapyard.

So what trains have TransPennine ordered?

AQll these trains will have single-doors at both end of each car. That’s classic crap design!

It will be interesting to see the average dwell time of a train on the Castlefield Corridor and compare it with that of Class 745 trains calling at Ipswich, Colchester and Chelmsford.

My money’s on Swiss clockwork!

Northern’s New Trains

Northern’s new Class 195 and Class 331 trains appear to have two sets of double-doors on each side of each car.

Now that’s more like it!

Improving Throughput On The Castlefield Corridor

If you look at successful high-capacity lines with a lot of stopping trains like most lines on the London Underground, Thameslink the Tyne and Wear Metro and the Merseyrail Northern Line, all trains are the same.

One of the problems with the trains through Castlefield, is that there are a lot of diffeent trains. So doors on your train may be in a different position to those on the previous train.

This means that passengers will be more likely to be in the wrong place, which means loading takes longer.

It is probably too much to get identical trains running on the route, but TransPennine’s trains with end doors will make matters worse for capacity.

I don’t think, any train should be allowed on the route, unless it has two sets of double-doors on each side of all cars.

The route should also have digital signalling.

If the North London Line can handle eight passenger and two freight trains per hour, then surely the Castlefield Corridor can do the same.

Passenger Behaviour

I was chatting to a station guy on Platform 14 at Piccadilly, who had also worked on the London Underground.

He told me, that Londoners obey his instructions to stand-back, whereas Mancunians don’t!

I watched for about twenty minutes and I think because the trains are rather bad time keepers, when one arrives everybody wants to get on immediately.

Single doors on TransPennine’s trains will make this behaviour worse!

Conclusion

I think Chris Grayling mades a good summary of the problems of doing major work on a busy passenger and freight corridor through a major city.

The only way to deal with the problems of the Castlefield Corridor, is a series of small improvements to the existing system.

  • All trains through the corridor must have two double-doors on each side of each car.
  • Digital signalling must be installed.
  • Platform access must be improved with lots of lifts and escalators.

I also feel that if the trains were running to the timetable, then passengers wouldn’t crowd the platforms.

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.

Dwell Times And End Doors

Chris Stokes finishes his column in the January 2019 Edition of  Modern Railways, with this paragraph.

Dwell times remain critical too. The new TransPennine units provide more seats, but have single end doors. For an operation with high numbers joining and alighting at many stops, dwell times are going to increase significantly at stations such as Manchester Victoria, Huddersfield, Leeds, Boltonand Preston, chewing up any savings in running times, and exacerbating the problems at platforms 13 and 14 at Manchester Piccadilly.

I haven’t seen a TransPennine Mark 5A coach in the flesh yet, but I’ve seen several pictures, which show each coach has single end doors.

This  picture of the 100 mph Class 755 train shows the door layout is totally different.

It looks like it has a single double door on each coach.

It appears that the electric Class 745 trains have more doors.

If you look at a typical Bombardier Aventra or Electrostar, Stadler Flirt or Siemens Desiro City, there are generally no end doors.

Have CAF commited a design crime of the highest order?

Or is it TransPennine’s fault?

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.

TPE Earmarks Top-And-Tail ’68s’ For Passenger Services

The title of this post is the same as that of an article in Issue 851 of Rail Magazine.

The article describes how TransPennine Express are going to use four Class 68 locomotives and four-carriage rakes of Mark 3 coaches to provide passenger services between Liverpool Lime Street and Scarborough.

From the 20th of May, services will leave Liverpool at 0556, 0656, 1156, 1256, 1756 and 1856 and Scarborough at 0846, 0946, 1446, 1546, 2050 and 2149.

TPE Pledges Capacity Boost With Class 68/Mk 5A Sets

The title of this post is the same as that of an article in Issue 851 of Rail Magazine.

It adds a few extra details to those, that I wrote about in Nova 3 On The Test Track.

This information is revealed.

The Route

The TransPennine Express fleet will run on the Liverpool Lime Street-Manchester Airport-Scarborough/Middlesbrough Routes, replacing three car Class 185 trains.

Train Length

Each Mark 5A car has a length of 22.2 or 22.37 metres.

Adding on the Class 68 locomotive gives a train length of 131.84 metres.

This compares with a train length for the Class 185 train of 71.276 metres.

It means that two Class 185 trains working together, which is current practice, are longer than the new fleet.

This must limit platform and depot modifications.

The Capacity

The number of seats on the two trains are as follows.

  • Class 185 train – 15 First Class – 165 Second Class
  • Class 68/Mk 5A sets – 30 First Class – 261 Second Class

This gives twice as many seats in First Class and nearly sixty percent more in second.

Both trains seem to have around sixty seats in each car.

Technical Characteristics

The Rail Magazine article gives several technical characteristics.

  • Each coach has two passenger doors, except the First Class coach which has one.
  • There is Selective Door Opening controlled by GPS.
  • Door controls are in the Driver Trailer and Class 68 cans, which the driver controls.
  • Two door control panels are in every vehicle for usde by the conductor.
  • Wheel Slip Protection is fitted.
  • Automatic passenger counting is provided.
  • Wi-fi is fitted.

The trains have a high specification.
