Middlesbrough Station – 20th October 2020

I took These pictures at Middlesbrough station on my trip to Teesside.

These are my thoughts on the station.

Station Track Layout

This Google Map shows the layout of the station.

Note.

  1. The pair of freight lines passing around the North side of the station.
  2. Platform 1 is the Westbound platform on the South side of the tracks.
  3. Platform 2 is the Eastbound platform on the North side of the tracks.

Both platforms would appear to be about 150 metres long, which is long enough for a five-car Class 80x train, but not for a 234 metre long nine-car train.

Period Features

The station has a lot of period features, like cast-iron columns and brackets, and good Victorian stonework.

Much seems to have received good TLC.

Northern Entrance

I have seen comments about improving the Northern entrance on various web sites.

It certainly, isn’t in bad condition.

Improving The Station

In £35m Station Transformation Launched By Tees Valley Mayor, I wrote about the current plans to transform the station. I started with these paragraphs.

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

This is the introductory paragraph.

Tees Valley Mayor Ben Houchen has announced (June 9th) a £35m transformation of Middlesbrough Station to transport more train services to the town, including the first direct rail link to London in decades.

The Rail Technology Magazine article indicates that Platform 2 at Middlesbrough station will be extended to handle Azuma trains. As the current platform looks to be around 150 metres long and this would be long enough for a five-car train, does this mean that in the future nine-car and ten-car Azumas will be able to run services to Middlesbrough?

Having seen since I wrote the related post, that Hull station has handled some nine-car Azumas, I feel that although five-car Azumas could probably use Middlesbrough station, it would seem prudent to make it possible for the longer trains to call.

Let’s suppose Middlesbrough, were playing a big London club in an important post-pandemic FA Cup match. LNER might want to run a nine-car Azuma to Middlesbrough to accommodate extra passengers.

Charging Battery Trains

LNER and TransPennine Express could be running battery electric Class 800 and Class 802 trains to Middlesbrough and/or Redcar Central stations.

This Hitachi infographic describes their Regional Battery Train, which can be created by adding batteries to the current trains.

With a range of 90 km. or 56 miles, these trains could be able to reach Middlesbrough from the electrification on the East Coast Main Line at Northallerton.

With most journeys, they should have sufficient energy in the battery to return without trouble.

But it would probably be prudent to have charging at Middlesbrough and/or Redcar Central to ensure a safe return.

These pictures were taken from the Eastern end of Platform 2, which is down to be lengthened.

Note.

  1. The freight lines behind Platform 2.
  2. There is plenty of space beyond the end of Platform 2.
  3. There appears to be space for a reversing siding with a charger.

I am sure that a suitable form of charging can be provided on Platform 2 at Middlesbrough station.

Conclusion

Middlesbrough station could be turned into a big asset for the town.

Hull Station

On my recent visit to Hull station I took these pictures.

This Google Map shows the station.

These are my thoughts on the station .

Platforms

Consider.

  • The station has seven platforms, which are numbers 1 to 7 from South to North.
  • My Hull Trains service from London arrived in the Northernmost platform, which is numbered 7.
  • Most Hull Trains services seem to use this platform.
  • LNER services also seem to use Platform 7.
  • Platforms 4, 5 and 6 seem to be the same length as Platform 7
  • A friendly station guy told me, that LNER have run nine-car Class 800 trains into the station. These trains are 234 metres long.
  • My pictures show that Platform 7 is more than adequate for Hull Train’s five-car Class 802 train, which is 130 metres long.
  • The platforms are wide.

This second Google Map shows the Western platform ends.

It looks to me, that the station should be capable of updating to have at least four platforms capable of taking trains, that are 200 metres long.

Current Long Distance Services To Hull Station

There are currently, two long distance services that terminate at Hull station.

  • One train per hour (tph) – Manchester Piccadilly – two hours
  • Eight trains per day (tpd) – London Kings Cross – two hours and forty-four minutes

Both services are run by modern trains.

Improvements To The Current London And Hull Service

I believe Hull Trains and LNER will run between London Kings Cross and Hull using battery-equipped versions of their Hitachi trains, within the next three years.

The trains will also be upgraded to make use of the digital in-cab signalling, that is being installed South of Doncaster, which will allow 140 mph running.

In Thoughts On Digital Signalling On The East Coast Main Line, I estimated that this could enable a two hours and thirty minute time between London Kings Cross and Hull.

It is very likely that the service will be hourly.

Hull Station As A High Speed Station

Plans for High Speed Two are still fluid, but as I said in Changes Signalled For HS2 Route In North, there is a possibility, that High Speed Two could be extended from Manchester Airport and Manchester Piccadilly to Leeds and ultimately to Newcastle and Hull.

In that post, I felt that services across the Pennines could be something like.

  • 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

There would be four tph between Manchester Airport and Hull via Manchester Piccadilly, Leeds and other intermediate stations.

I estimate that the following timings would be possible.

  • London Euston and Hull – two hours and 10 minutes – Currently two hours and forty-four minutes to London Kings Cross
  • Liverpool and Hull – one hour and thirty minutes – No direct service
  • Manchester and Hull – one hour and three minutes – Currently two hours

As I said earlier London Kings Cross and Hull could be only twenty minutes longer by the classic route on the East Coast Main Line.

I think it will be likely, that both High Speed Two and Northern Powerhouse Rail will use similar High Speed Two Classic-Compatible trains, which will have the following characteristics.

  • Two hundred metres long
  • Ability to run in pairs
  • 225 mph on High Speed Two
  • 125 mph and up to 140 mph on Classic High Speed Lines like East Coast Main Line, Midland Main Line and West Coast Main Line and sections of Northern Powerhouse Rail.

It would appear that as Hull station can already handle a nine-car Class 800 train, which is 234 metre long, it could probably handle the proposed High Speed Two Classic-Compatible trains.

I could see the following numbers of high speed trains terminating at Hull in a typical hour would be as follows.

  • Two High Speed Two trains from London Euston
  • Two Northern Powerhouse Trains from Liverpool Lime Street
  • One Hull Trains/LNER train from London Kings Cross

As Hull already has four platforms, that can accept 200 metre long trains, I don’t think the station will have any capacity problems.

Charging Battery Trains At Hull Station

If Hull Trains, LNER and TransPennine Express, decide to convert their Class 800 and Class 802 trains, that run to and from Hull to Hitachi Regional Battery Trains, they will need charging at Hull station, to be able to reach the electrification of the East Coast Main Line at Temple Hirst Junction.

In Thoughts On The Design Of Hitachi’s Battery Electric Trains, I said this about having a simple charger in a station.

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

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

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

Platforms 4 to 7 could be fitted out in this manner, to obtain maximum operational flexibility.

Full Electrification Of Hull Station

Full electrification of Hull station would also allow charging of any battery electric trains.

I would hope, that any partial electrification carried out to be able to charge trains would be expandable to a full electrification for the station and the connecting rail lines.

A Full Refurbishment

The station would need a full refurbishment and a possible sorting out of the approaches to the station.

But this type of project has been performed at Kings Cross and Liverpool Lime Street in recent years, so the expertise is certainly available.

These pictures are of Liverpool Lime Street station.

I could see Hull station being refurbished to this standard.

Conclusion

It is my belief that Hull would make a superb terminal station for both High Speed Two and Northern Powerhouse Rail

In the interim, it could be quickly developed as a modern terminal for long-distance battery electric trains to make services across the Pennines and to London zero carbon.

The work could also be organised as a series of smaller work packages, without interrupting train services to and from Hull.

Thoughts On The Design Of Hitachi’s Battery Electric Trains

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

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

There have been rumours of overheating.

Hitachi’s Regional Battery Train

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

This Hitachi infographic gives the specification.

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

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

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

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

There are many similar routes like this in the UK.

Hitachi have also produced this video.

My thoughts lead me to a few questions.

Are The Battery Modules Simulated Diesel Engines?

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

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

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

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

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

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

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

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

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

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

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

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

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

Perhaps for various routes different combinations might apply.

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

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

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

Operators will like this flexibility.

What Is The Capacity Of A Battery Module?

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

I can do a simple estimate based on this figure.

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

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

I will compromise and use 2.5 kWh per vehicle mile.

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

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

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

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

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

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

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

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

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

But would increasing the battery size make this possible?

Where Do Avanti West Coast Class 807 Trains Fit In?

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

Note.

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

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

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

Running With Batteries And A Range Extender Diesel Engine

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

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

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

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

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

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

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

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

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

Charging Battery Trains

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

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

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

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

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

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

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

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

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

Conclusion

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

Greater Anglia Amends Class 720 Order From Bombardier To Increase Flexibility

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

Greater Anglia is changing its order for Class 720 trains from a mixed fleet of 22 x ten-car and 89 x five-car to one of 133 x five-car.

The order is still 665 carriages in total.

In Why Do Some Train Operators Still Buy Half-Trains?, I tried to answer the question in the title of the post.

There have also been articles in railway magazines, questioning the practice of buying short trains and doubling them up.

In the UK, the following companies are running new trains in pairs.

  • Great Western Railway – Class 800 and Class 802
  • LNER – Class 800
  • London Overground – Class 710

The only creditable explanation I have heard was from a driver, who said that if one train in a pair fails, you can still run a short train.

Abd now Greater Anglia say it’s for increased flexibility!

Hitachi Targets Export Opportunities From Newton Aycliffe

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

This is the introductory paragraph.

Very High Speed Trains (VHSTs) built in Britain could be exported to Europe and even further afield from Hitachi’s Newton Aycliffe factory.

The article would appear to confirm, that the AT-300 family of trains is now a family with a very wide reach.

Trains in the family include.

Very High Speed Trains (VHST)

The article states that VHST trains will form part of the AT-300 family.

The big order to be handed out in the UK, is for 54 Classic-Compatible trains for High Speed Two.

The Classic-Compatible trains are described in this section in Wikipedia, by this sentence.

The classic-compatible trains, capable of high speed but built to a British loading gauge, permitting them to leave the high speed track to join conventional routes such as the West Coast Main Line, Midland Main Line and East Coast Main Line. Such trains would allow running of HS2 services to the north of England and Scotland, although these non-tilting trains would run slower than existing tilting trains on conventional track. HS2 Ltd has stated that, because these trains must be specifically designed for the British network and cannot be bought “off-the-shelf”, these conventional trains were expected to be around 50% more expensive, costing around £40 million per train rather than £27 million for the captive stock.

The trains will have the same characteristics as the full-size High Speed Two trains.

  • Maximum speed of 225 mph.
  • Cruising speed of 205 mph on High Speed Two.
  • Length of 200 metres.
  • Ability to work in pairs.
  • A passenger capacity around 500-600 passengers.

A seven-car Class 807 train with twenty-six metre long cars would appear to be a partial match and tick all the boxes, except for the following.

  • The train’s maximum and cruising speeds are well below what is needed.
  • The train is only 182 metres long.
  • The train has a passenger capacity of 453.

Would a train with eight twenty-five metre long cars be a better fit?

  •  The train length would be 200 metres.
  • Twenty-five metre cars would not cause a problem!
  • I estimate the passenger capacity would be 498 seats.

The trains or members of the same family have already shown.

  • They can run on the East Coast, Great Western, Midland and West Coast Main Lines.
  • They can run on High Speed One.
  • They can split and join automatically.
  • When needed they can run on local lines.

If I was Avanti West Coast’s train-Czar, I would be seriously interested in a Classic-Compatible High Speed Two train, that was very similar to one I already had in service. Provided, of course it did what it promised in the specification.

By adjusting the car-length and the number of cars, the Classic-Compatible High Speed Two train can probably made to fit any operators needs.

High Speed Trains (HST)

There are several fleets of these in service.

The picture shows one of LNER’s Hitachi trains going through Oakleigh Park station.

It would appear that the trains can be configured to the customers needs.

  • Trains have been ordered in lengths of five, seven or nine cars, with a maximum length of up to twelve or more cars.
  • Cars have been ordered in lengths of 24 and 26 metres.
  • Some fleets will be fitted with diesel engines for bi-mode operation.

Operating speeds will be as follows.

  • 100 mph operating speed on diesel.
  • 125 mph operating speed on electric power
  • 140 mph operating speed on electric power with in-cab signalling.

The signalling required for 140 mph running, is currently being installed between London Kings Cross and Doncaster.

High Speed Commuter Trains

As high speed lines proliferate, there will be a need for faster commuter trains.

In a few years time, the following lines out of London will see High Speed Trains like those made by Hitachi sharing tracks with commuter trains.

  • East Coast Main Line
  • Midland Main Line
  • West Coast Main Line
  • Great Western Main Line

Already on the Great Western Main Line services to Bedwyn and Oxford are run by Class 800 or Class 802 trains, so these trains could be considered to be High Speed Commuter Trains.

  • Their 125 mph operating speed allows them to mix it, with the other High Speed Trains running into and out of London Paddington.
  • Digital in-cab signalling may allow running of both expresses and High Speed Commuter trains at 140 mph.

Other routes, where they could be used, would include.

  • London Kings Cross and Ely via Cambridge.
  • London Paddington and Cheltenham
  • London Paddington and Westbury
  • London St. Pancras and Corby.
  • Liverpool And Blackpool
  • Liverpool And Crewe

The trains would only be doing the same as already happens on High Speed One.

As more and more High Speed Trains run in the UK on existing 125 mph routes, there will be a greater need to increase the operating speed of commuter trains sharing the routes.

Regional Battery Trains

I described these trains in Hyperdrive Innovation And Hitachi Rail To Develop Battery Tech For Trains.

Their specification is given in this Hitachi infographic.

A Regional Battery Train has the following capabilities on battery power.

  • 100 mph operating speed.
  • Ability to run for 56 miles.

It appears that all AT-300 based trains could be converted into either Regional Battery Trains or AT-300 trains fitted with batteries.

If you take one of Great Western Railway’s Class 802 trains, it will have the following specification.

  • 125 mph operating speed on electric power
  • 140 mph operating speed on electric power with in-cab signalling.

These speeds will be unaffected by fitting batteries, as when running using electrification, the batteries will effectively be more passengers, just as any diesel engines are today.

I also believe that the trains could be Plug-and-Play, with interchangeable diesel engines and battery packs. The train’s operating system would determine how much power was available and drive the car accordingly.

I also believe that Hitachi are being economical with the truth on range on battery power and that if every car was fitted with an intelligent battery pack, on some routes the range could be much greater in a few years.

As an example of their use, Harrogate is eighteen miles from electrification at Leeds. With a range of 56 miles, a Regional Battery Train could do the following.

  • Travel from London Kings Cross to Leeds using the existing electrification.
  • Travel from Leeds to Harrogate and back on battery power.
  • Travel back to London Kings Cross from Leeds using the existing electrification.

Note.

  1. Trains would charge their batteries on the run up from London Kings Cross.
  2. Trains would be travelling at up to 125 mph between London Kings Cross and Leeds.
  3. Once in-cab signalling is installed between London and Doncaster, this section could be run at up to 140 mph.

This battery train is no glorified milk-float!

There are other services off high speed lines , that could be handled

  • Bedwyn – 13 miles
  • Harrogate – 18 miles
  • Henley – 4.5 miles
  • Huddersfield – 17 miles
  • Lincoln – 16.5 miles
  • Oxford – 10.5 miles

These are just a few of many examples, which are probably increased by a factor of two or three if you have charging at both ends of route without electrification.

Conclusion

Hitachi have developed a family of high speed trains, that can handle anything from fast commuter trains to very high speed trains.

They also probably have battery options to fit all of them.

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

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

This is the introductory paragraph.

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

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

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

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

How many trains will be needed to cover these routes?

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

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

But some of these trains will be extended past Leeds.

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

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

It appears that the following is true.

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

Note.

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

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

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

Wikipedia also says this.

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

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

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

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

This would need the following trains.

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

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

Are InterCity 225 Trains Already Certified For 140 mph Running?

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

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

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

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

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

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

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

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

A Fleet Of Seven Trains Would Cover Bradford And Skipton Services

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

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

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

Not Enough Five-Car Bi-Mode Class 800 Trains

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

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

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

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

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

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

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

The trains should be able to serve these routes.

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

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

Conclusion

I think it is a good plan.

Hull Issues New Plea For Electrification

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

This is the introductory paragraph.

Residents and businesses in Hull are being urged to support electrification of the railway to Selby and Sheffield.

This paragraph is about the difficulty of electrifying the route.

“Unlike elsewhere on the trans-Pennine routes, work here can start straightaway and would be a quick win. Our plans involve few extra land purchases, no tunnel widening, and no re-routing,” said Daren Hale, Hull City Council and Hull’s representative on the Transport for the North board.

Services to Hull station are as follows.

  • Hull Trains – London Kings Cross and Hull via Selby, Howden and Brough.
  • Hull Trains – Beverley and Hull via Cuttingham
  • LNER – London Kings Cross and Hull via Selby and Brough
  • Northern Trains – Halifax and Hull via Bradford Interchange, New Pudsey, Bramley, Leeds, Cross Gates, Garforth, East Garforth, Micklefield, South Milford, Selby and Brough
  • Northern Trains – Sheffield and Hull via Meadowhall, Rotherham Central, Swinton, Mexborough, Conisbrough, Doncaster, Kirk Sandall, Hatfield & Stainforth, Thorne North, Goole, Saltmarshe, Gilberdyke, Broomfleet, Brough, Ferriby and Hessle,
  • Northern Trains – Bridlington and Hull via Nafferton, Driffield, Hutton Cranswick, Arram, Beverley and Cottingham.
  • Northern Trains – Scarborough and Hull via Seamer, Filey, Hunmanby, Bempton, Bridlington, Nafferton, Driffield, Hutton Cranswick, Arram, Beverley and Cottingham.
  • Northern Trains – York and Hull via Selby, Howden, Gilberdyke and Brough.
  • TransPennine Express – Manchester Piccadilly and Hull via Stalybridge, Huddersfield, Leeds, Selby, Brough

Note.

  1. Some services are joined back-to-back with a reverse at Hull station.
  2. I have simplified some of the lists of intermediate stations.
  3. Services run by Hull Trains, LNER or TransPennine Express use bi-mode Class 800 or Class 802 trains.
  4. All routes to Hull station and the platforms are not electrified.

Trains approach Hull by three routes.

  • Selby and Brough
  • Goole and Brough
  • Beverley and Cottingham

Could these three routes be electrified?

I have just flown my helicopter along all of them.

I’ve also had a lift in the cab of a Class 185 train between Hull and Leeds, courtesy of Don Coffey.

Hull And Selby via Brough

There is the following infrastructure.

  • Several major road overbridges, which all seem to have been built with clearance for overhead wires.
  • There are also some lower stone arch bridges, which may need to be given increased clearance.
  • No tunnels
  • The historic Selby Swing Bridge.
  • Four farm crossings.
  • Fourteen level crossings.

Hull And Goole via Brough

There is the following infrastructure.

  • Several major road overbridges, which all seem to have been built with clearance for overhead wires.
  • No tunnels
  • A swing bridge over the River Ouse.
  • A couple of farm crossings
  • Six level crossings

Hull And Beverley via Cottingham

There is the following infrastructure.

  • A couple of major road overbridges, which all seem to have been built with clearance for overhead wires.
  • No tunnels
  • A couple of farm crossings
  • Six level crossings

All of the routes would appear to be.

  • At least double track.
  • Not in deep cuttings.
  • Mainly in open countryside.

I feel that compared to some routes, they would be easy to electrify, but could cause a lot of disruption, whilst the level crossings and the two swing bridges were electrified.

Speeding Up Services To And From Hull

What Are The Desired  Timings?

The Rail Magazine article says this about the desired timings.

Should the plans be approved, it is expected that Hull-Leeds journey times would be cut from 57 minutes to 38, while Hull-Sheffield would drop from 86 minutes to 50 minutes.

These timings are in line with those given in this report on the Transport for the North web site, which is entitled At A Glance – Northern Powerhouse Rail,

The frequency of both routes is given in the report as two trains per hour (tph)

The Performance Of An Electric Class 802 Train

As Hull Trains, LNER and TransPennine Express will be using these trains or similar to serve Hull, I will use these trains for my calculations.

The maximum speed of a Class 802 train is 125 mph or 140 mph with digital in-cab signalling.

This page on the Eversholt Rail web site, has a data sheet for a Class 802 train.

The data sheet shows the following for a five-car Class 802 train.

It can accelerate to 100 mph and then decelerate to a stop in 200 seconds in electric mode.

The time to 125 mph and back is 350 seconds

Thoughts On Hull And Leeds

Consider.

  • The Hull and Leeds route is 52 miles long, is timed for a 75 mph train and has an average speed of 55 mph
  • There are three intermediate stops, which means that in a Hull and Leeds journey, there are four accelerate-decelerate cycles.
  • A 38 minute journey between Hull and Leeds would be an average speed of 82 mph
  • A train travelling at 100 mph would take 31 minutes to go between Hull and Leeds.
  • A train travelling at 125 mph would take 25 minutes to go between Hull and Leeds.

I also have one question.

What is the speed limit on the Selby Swing Bridge?

I have just been told it’s 25 mph. As it is close to Selby station, it could probably be considered that the stop at Selby is a little bit longer.

These could be rough timings.

  • A train travelling at 100 mph would take 31 minutes to go between Hull and Leeds plus what it takes for the four stops. at 200 seconds a stop, which adds up to 43 minutes.
  • A train travelling at 125 mph would take 25 minutes to go between Hull and Leeds plus what it takes for the four stops. at 350 seconds a stop, which adds up to 48 minutes.

Note how the longer stopping time of the faster train slows the service.

I think it would be possible to attain the required 38 minute journey, running at 100 mph.

Thoughts On Hull And Sheffield

Consider.

  • The Hull and Sheffield route is 61 miles long, is timed for a 90 mph train and has an average speed of 43 mph
  • There are five intermediate stops, which means that in a Hull and Sheffield journey, there are six accelerate-decelerate cycles.
  • A 50 minute journey between Hull and Leeds would be an average speed of 73 mph.
  • A train travelling at 100 mph would take 36 minutes to go between Hull and Sheffield.
  • A train travelling at 125 mph would take 29 minutes to go between Hull and Sheffield.

I also have one question.

What is the speed limit on the swing bridge over the River Ouse?

As there is no nearby station, I suspect it counts as another stop, if it only has a 25 mph limit.

These could be rough timings.

  • A train travelling at 100 mph would take 36 minutes to go between Hull and Sheffield plus what it takes for the six stops. at 200 seconds a stop, which adds up to 56 minutes.
  • A train travelling at 125 mph would take 29 minutes to go between Hull and Sheffield plus what it takes for the six stops. at 350 seconds a stop, which adds up to 64 minutes.

Note how the longer stopping time of the faster train slows the service.

I think it would be possible to attain the required 50 minute journey, running at 100 mph.

Conclusions From My Rough Timings

Looking at my rough timings, I can conclude the following.

  • The trains will have to have  the ability to make a station stop in a very short time. Trains using electric traction are faster at station stops.
  • The trains will need to cruise at a minimum of 100 mph on both routes.
  • The operating speed of both routes must be at least 100 mph, with perhaps 125 mph allowed in places.
  • I feel the Hull and Leeds route is the more difficult.

I also think, that having a line running at 100 mph or over, with the large number of level crossings, there are at present, would not be a good idea.

What Does Hull Want?

Hull wants what Northern Powerhouse Rail is promising.

  • Two tph between Hull and Leeds in 38 minutes and Hull and Sheffield in 50 minutes.

They’d probably also like faster electric services between Hull and Bridlington, London Kings Cross, Manchester, Scarborough and York.

When Do They Want It?

They want it now!

Is There An Alternative Solution, That Can Be Delivered Early?

This may seem to be the impossible, as electrifying between Hull and Leeds and Hull and Sheffield is not an instant project, although full electrification could be an ultimate objective.

Consider.

  • Hull and Brough are 10.5 miles apart.
  • Brough and Leeds are 41 miles apart.
  • Brough and Doncaster are 30 miles apart and Doncaster and Sheffield are 20 miles apart.
  • Brough and Temple Hirst Junction are 26 miles apart.
  • Brough and York are 42 miles apart.
  • Hull and Beverley are 8 miles apart.
  • Beverley and Bridlington are 23 miles apart.
  • Beverley and Seamer are 42 miles apart.

Note that Doncaster, Leeds and Temple Hirst Junction are all electrified.

Hitachi’s Regional Battery Train

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

It has a range of 56 miles and an operating speed of 100 mph.

Class 800 and Class 802 trains could be converted into Regional Battery Trains.

  • The three diesel engines would be exchanged for battery packs.
  • The trains would still be capable of 125 mph on fully-electrified routes like the East Coast Main Line.
  • They would be capable of 100 mph on routes like the 100 mph routes from Hull.
  • The trains would have full regenerative braking to batteries, which saves energy.
  • Below 125 mph, their acceleration and deceleration on battery power would probably be the same as when using electrification. It could even be better due to the simplicity and low impedance of batteries.

But they would need some means of charging the batteries at Hull.

A Start To Electrification

If the ultimate aim is to electrify all the lines, then why not start by electrifying.

  • Hull station.
  • Hull and Brough
  • Hull and Beverley

It would only be 18.5 miles of electrification and it doesn’t go anywhere near the swing bridges or about six level crossings.

Battery Electric Services From Hull

I will now look at how the various services could operate.

Note in the following.

  1. When I say Regional Battery Train, I mean Hitachi’s proposed train or any other battery electric train with a similar performance.
  2. I have tried to arrange all power changeovers in a station.
  3. Pantograph operation can happen at line-speed or when the train is stationary.

I have assumed a range of 56 miles on a full battery and an operating speed of 100 mph on a track that allows it.

Hull And London Kings Cross

The legs of the service are as follows.

  • Hull and Brough – 10.5 miles – Electrified
  • Brough and Temple Hirst Junction – 26 miles – Not Electrified
  • Temple Hirst Junction and London Kings Cross – 169 miles – Electrified

Note.

  1. Hull and Brough takes about 11 minutes, so added to the time spent in Hull station, this must be enough time to fully-charge the batteries.
  2. Regional Battery Trains will be able to do 56 miles on a full battery so 26 miles should be easy.
  3. One changeover between power sources will be done in Brough station.
  4. The other changeover will be done at line speed at Temple Hirst Junction, as it is now!

Hull Trains and LNER would be able to offer an all-electric service to London.

A few minutes might be saved, but they would be small compared to time savings, that will be made because of the introduction of full ERTMS in-cab signalling South of Doncaster, which will allow 140 mph running.

Hull And Leeds

The legs of the service are as follows.

  • Hull and Brough – 10.5 miles – Electrified
  • Brough and Leeds – 41 miles – Not Electrified

Note.

  1. Hull and Brough takes about 11 minutes, so added to the time spent in Hull station, this must be enough time to fully-charge the batteries.
  2. Regional Battery Trains will be able to do 56 miles on a full battery so 41 miles should be easy.
  3. One changeover between power sources will be done in Brough station, with the other in Leeds station.

If Leeds and Huddersfield is electrified, TransPennine Express will be able to run an all-electric service between Manchester and Hull, using battery power in the gaps.

Hull And Sheffield

The legs of the service are as follows.

  • Hull and Brough – 10.5 miles – Electrified
  • Brough and Doncaster – 30 miles – Not Electrified
  • Doncaster and Sheffield – 20 miles – Not Electrified

Note.

  1. Hull and Brough takes about 11 minutes, so added to the time spent in Hull station, this must be enough time to fully-charge the battery.
  2. Regional Battery Trains will be able to do 56 miles on a full battery so 30 miles should be easy.
  3. Trains would charge using the electrification at Doncaster.
  4. Doncaster and Sheffield both ways should be possible after a full charge at Doncaster station.
  5. One changeover between power sources will be done in Brough station, with the others in Doncaster station.

Hull And York

The legs of the service are as follows.

  • Hull and Brough – 10.5 miles – Electrified
  • Brough and York- 42 miles – Not electrified

Note.

  1. Hull and Brough takes about 11 minutes, so added to the time spent in Hull station, this must be enough time to fully-charge the batteries.
  2. Regional Battery Trains will be able to do 56 miles on a full battery so 42 miles should be easy.
  3. One changeover between power sources will be done in Brough station, with the other in York station.
  4. Trains would be fully charged for the return in York station.

This journey will also be effected by the York to Church Fenton Improvement Scheme, which is described on this page on the Network Rail web site. According to the web page this involves.

  • Replace old track, sleepers, and ballast (The stones which support the track)
  • Install new signalling gantries, lights, and cabling
  • Fully electrify the route from York to Church Fenton – extending the already electrified railway from York.

There will be another five miles of electrification., which will mean the legs of the Hull and York service will be as follows.

  • Hull and Brough – 10.5 miles – Electrified
  • Brough and Church Fenton – 31.5 miles – Not Electrified
  • Church Fenton and York – 10.5 miles – Electrified

It is a classic route for a battery electric train.

Note.

  1. Church Fenton and York takes about 19 minutes, so added to the time spent in York station, this must be enough time to fully-charge the batteries.
  2. There will be a changeover between power sources in Church Fenton station.

This appears to me to be a very sensible addition to the electrification.

If you look at a Leeds and York, after the electrification it will have two legs.

  • Leeds and Church Fenton – 13 miles – Not Electrified
  • Church Fenton and York – 10.5 miles – Electrified

It is another classic route for a battery electric train.

Hull And Bridlington

The legs of the service are as follows.

  • Hull and Beverley – 13 miles – Electrified
  • Beverley and Bridlington – 23 miles – Not Electrified

Note.

  1. Hull and Beverley takes about 13 minutes, so added to the time spent in Hull station, this must be enough time to fully-charge the batteries.
  2. Regional Battery Trains will be able to do 56 miles on a full battery so 46 miles to Bridlington and back to Beverley, should be possible.
  3. The changeovers between power sources would be in Beverley station.

If necessary, there is a bay platform at Bridlington, that could be fitted with simple electrification to charge the trains before returning.

Hull And Scarborough

The legs of the service are as follows.

  • Hull and Beverley – 13 miles – Electrified
  • Beverley and Seamer- 42 miles – Not Electrified
  • Seamer and Scarborough – 3 miles – Not Electrified

Note.

  1. Hull and Beverley takes about 13 minutes, so added to the time spent in Hull station, this must be enough time to fully-charge the batteries.
  2. Regional Battery Trains will be able to do 56 miles on a full battery so 45 miles to Scarborough should be easy.
  3. The changeovers between power sources would be in Beverley station.

There would need to be charging at Scarborough, so why not electrify between Scarborough and Seamer?

  • Power changeover would be in Seamer station.
  • The electrification could also charge battery electric trains running between York and Scarborough.
  • Seamer and York are 39 miles apart.
  • All Northern Trains and TransPennine Express services appear to stop in Seamer station.

This could be three very useful miles of electrification.

Could This Plan Based On Battery Trains Be Delivered Early?

The project could be divided into sub-projects.

Necessary Electrification

Only these double-track routes would need to electrified.

  • Hull and Brough
  • Hull and Beverley
  • Seamer and Scarborough

There would also be electrification at Hull and Scarborough stations to charge terminating trains.

In total it would be under twenty-five double-track miles of electrification.

Note.

  1. There are no swing bridges on these routes.
  2. There are no tunnels
  3. Many of the overbridges appear to be modern with adequate clearance for electrification.
  4. I don’t suspect that providing adequate power will be difficult.
  5. Hull and Scarborough are larger stations and I believe a full service can be provided, whilst the stations are being electrified.

It would not be a large and complicated electrification project.

Conversion Of Class 800 And Class 802 Trains To Regional Battery Trains

Whilst the electrification was being installed, the existing Class 800 and Class 802 trains needed by Hull Trains, LNER and TransPennine Express could be converted to Regional Battery Trains, by the replacement of some or all of the diesel engines with battery power-packs.

I suspect LNER or GWR could be the lead customer for Hitachi’s proposed conversion of existing trains.

  • Both train companies have routes, where these trains could be deployed without any electrification or charging systems. Think London Kings Cross and Harrogate for LNER and  Paddington and Oxford for GWR.
  • Both train companies have large fleets of five-car trains, that would be suitable for conversion.
  • Both train companies have lots of experience with Hitachi’s trains.

It should be noted that GWR, Hull Trains and TransPennine Express are all part of the same company.

What About Northern Trains?

Northern Trains will need some battery electric trains, if this plan goes ahead, to run routes like.

  • Hull and Bridlington – 46 miles
  • Hull and Leeds – 41 miles
  • Hull and Scarborough – 42 miles
  • Hull and Sheffield – 40 miles
  • Hull and York – 42 miles
  • Scarborough and York – 31.5 miles
  • The distances are the lengths of the route without electrification.

I suspect they will need a train with this specification.

  • Four cars
  • Ability to use 25 KVAC overhead electrification.
  • Battery range of perhaps 50 miles.
  • 100 mph operating speed.

There are already some possibilities.

  • CAF are talking about a four-car battery electric version of the Class 331 train.
  • Hitachi have mentioned a battery electric Class 385 train.
  • Porterbrook have talked about converting Class 350 trains to battery electric operation.
  • Bombardier have talked about battery electric Aventras.

There are also numerous four-car electric trains, that are coming off lease that could be converted to battery electric operation.

When Could The Project Be Completed?

There are three parts to the project.

  • Under twenty-five double-track miles of electrification.
  • Adding batteries to Class 800 and Class 802 trains.
  • Battery electric trains for Northern.

As the sub-projects can be progressed independently, I can see the project being completely by the end of 2024.

Across The Pennines In A Regional Battery Train

By providing the ability to run Class 802 trains on battery power to Hull and Scarborough, the ability to run Regional Battery Trains from Liverpool in the West to Hull, Middlesbrough and Scarborough in the East under electric power, could become possible.

Looking at Liverpool and Scarborough, there are these legs.

  • Liverpool Lime Street and Manchester Victoria – 32 miles – Electrified
  • Manchester Victoria and Stalybridge – 8 miles – Not Electrified
  • Stalybridge and Huddersfield – 18 miles – Not Electrified
  • Huddersfield and Leeds – 17 miles – Not Electrified
  • Leeds and York – 26 miles – Not Electrified
  • York and Scarborough – 42 miles – Not Electrified

Note.

  1. East of Manchester Victoria, there is electrification in Leeds and York stations, which could charge the train fully if it were in the station for perhaps ten minutes.
  2. Currently, stops at Leeds and York are around 4-5 minutes.
  3. Manchester Victoria and Stalybridge is being electrified.
  4. In this post, I have suggested that between Seamer and Scarborough should be electrified to charge the trains.
  5. I have also noted that between Church Fenton and York is being fully electrified.

This could mean power across the Pennines between Liverpool and Scarborough could be as follows.

  • Liverpool Lime Street and Manchester Victoria – 32 miles – Electrification Power and Charging Battery
  • Manchester Victoria and Stalybridge – 8 miles – Electrification Power and Charging Battery
  • Stalybridge and Huddersfield – 18 miles – Battery Power
  • Huddersfield and Leeds – 17 miles – Battery Power
  • Leeds station – Electrification Power and Charging Battery
  • Leeds and Church Fenton – 13 miles – Battery Power
  • Church Fenton and York – 10.5 miles – Electrification Power and Charging Battery
  • York and Seamer – 39 miles – Battery Power
  • Seamer and Scarborough – 3 miles – Electrification Power and Charging Battery

There are three stretches of the route, where the train will be run on battery power.

  • Stalybridge and Leeds – 35 miles
  • Leeds and Church Fenton – 13 miles
  • York and Seamer – 39 miles

There will be charging at these locations.

  • West of Stalybridge
  • Through Leeds Station
  • Through York Station
  • East of Seamer Station

I feel it could be arranged that trains left the charging sections and stations with a full battery, which would enable the train to cover the next section on battery power.

To make things even easier, Network Rail are developing the Huddersfield And Westtown Upgrade, which will add extra tracks and eight miles of new electrification between Huddersfield and Dewsbury.

This would change the power schedule across the Pennines between Liverpool and Scarborough to this.

  • Liverpool Lime Street and Manchester Victoria – 32 miles – Electrification Power and Charging Battery
  • Manchester Victoria and Stalybridge – 8 miles – Electrification Power and Charging Battery
  • Stalybridge and Huddersfield – 18 miles – Battery Power
  • Huddersfield and Dewsbury – 8 miles – Electrification Power and Charging Battery
  • Fewsbury and Leeds – 9 miles – Battery Power
  • Leeds station – Electrification Power and Charging Battery
  • Leeds and Church Fenton – 13 miles – Battery Power
  • Church Fenton and York – 10.5 miles – Electrification Power and Charging Battery
  • York and Seamer – 39 miles – Battery Power
  • Seamer and Scarborough – 3 miles – Electrification Power and Charging Battery

There are now four stretches of the route, where the train will be run on battery power.

  • Stalybridge and Huddersfield – 18 miles
  • Dewsbury and Leeds – 9 miles
  • Leeds and Church Fenton – 13 miles
  • York and Seamer – 39 miles

I can envisage the electrification being extended.

But battery power on this route gives all the advantages of electric trains, with none of the costs and installation problems of electrification.

Conclusion

I believe a limited electrification of lines for a few miles from the coastal terminals at Hull and Scarborough and battery electric trains can deliver zero-carbon and much faster electric trains to the railways of Yorkshire to the East of Leeds, Sheffield and York.

If this approach is used, the electrification will be much less challenging and if skates were to be worn, the scheme could be fully-implemented in around four years.

The scheme would also deliver the following.

  • Faster, all-electric TransPennine services.
  • An all-electric Hull and London service.
  • A substantial move towards decarbonisation of passenger train services in East Yorkshire.

It is also a scheme, that could be extended South into Lincolnshire, across the Pennines to Lancashire and North to Teesside and Tyneside.

GWR Buys Vehicles Outright In HST Fleet Expansion

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

This is the introductory paragraph.

Despite concerns over future passenger numbers, the Department for Transport has given permission for Great Western Railway to procure three more shortened HST diesel trainsets, branded as the Castle Class by the franchisee.

These pictures show some of the Castle Class trains.

They must be profitable and/or popular with passengers.

If I have a problem with these trains, it is with the Class 43 diesel power cars.

  • Each train has two power cars.
  • It would appear that there are about 150 of the Class 43 power cars in regular service.
  • Each is powered by a modern MTU 16V4000 R41R diesel engine, that is rated at 1678 kW.
  • The engines are generally less than a dozen years old.
  • They will be emitting a lot of carbon dioxide.

As the trains are now only half as long as they used to be, I would suspect, that the engines won’t be working as hard, as they can.

Hopefully, this will mean less emissions.

The article says this about use of the fleet.

With its fleet now increasing to 14, GWR expects to use 12 each day on services across the west of England. Currently the fleet is deployed on the Cardiff – Bristol – Penzance corridor, but the company is still evaluating how the additional sets will be used.

It also says, that they are acquiring rolling stock from other sources. Some of which will be cannibalised for spares.

Are First Rail Holdings Cutting Carbon Emissions?

First Rail Holdings, who are GWR’s parent, have announced in recent months three innovative and lower-carbon fleets from Hitachi, for their subsidiary companies.

Hitachi have also announced a collaboration with Hyperdrive Innovation to provide battery packs to replace diesel engines, that could be used on Class 800 and Class 802 trains.

First Rail Holdings have these Class 800/802 fleets.

  • GWR – 36 x five-car Class 800 trains
  • GWR – 21 x nine-car Class 800 trains
  • GWR – 22 x five-car Class 802 trains
  • GWR – 14 x nine-car Class 802 trains
  • TransPennine Express – 19 x five-car Class 802 trains
  • Hull Trains – 5 x five-car Class 802 trains

Note.

  1. That is a total of 117 trains.
  2. As five-car trains have three diesel engines and nine-car trains have five diesel engines, that is a total of 357 engines.
  3. In Could Battery-Electric Hitachi Trains Work Hull Trains’s Services?, I showed that Hull Trains could run their services with a Fast Charging system in Hull station.
  4. In Could Battery-Electric Hitachi Trains Work TransPennine Express’s Services?, I concluded that Class 802 trains equipped with batteries could handle all their routes without diesel and some strategically-placed charging stations.

In the Wikipedia entry for the Class 800 train, there is a section called Powertrain, where this is said.

According to Modern Railways magazine, the limited space available for the GUs has made them prone to overheating. It claims that, on one day in summer 2018, “half the diagrammed units were out of action as engines shut down through overheating.

So would replacing some diesel engines with battery packs, also reduce this problem, in addition to cutting carbon emissions?

It does appear to me, that First Rail Holdings could be cutting carbon emissions in their large fleet of Hitachi Class 800 and Class 802 trains.

The Class 43 power cars could become a marketing nightmare for the company?

Could Class 43 Power Cars Be Decarbonised?

Consider.

  • Class 43 power cars are forty-five years old.
  • They have been rebuilt with new MTU engines in the last dozen years or so.
  • I suspect MTU and GWR know everything there is to know about the traction system of a Class 43 power car.
  • There is bags of space in the rear section of the power car.
  • MTU are part of Rolls-Royce, who because of the downturn in aviation aren’t performing very well!

But perhaps more importantly, the power cars are iconic, so anybody, who decarbonises these fabulous beasts, gets the right sort of high-class publicity.

I would also feel, if you could decarbonise these power cars, the hundreds of diesel locomotives around the world powered by similar diesel engines could be a useful market.

What methods could be used?

Biodiesel

Running the trains on biodiesel would be a simple solution.

  • It could be used short-term or long-term.
  • MTU has probably run the engines on biodiesel to see how they perform.
  • Biodiesel could also be used in GWR’s smaller diesel multiple units, like Class 150, 158, 165 and 166 trains.

Some environmentalists think biodiesel is cheating as it isn’t zero-carbon.

But it’s my view, that for a lot of applications it is a good interim solution, especially, as companies like Altalto, will be making biodiesel and aviation biofuel from household and industrial waste, which would otherwise be incinerated or go to landfill.

The Addition Of Batteries

This page on the Hitachi Rail Ltd web site shows this image of the V-Train 2.

This is the introduction to the research program, which was based on a High Speed Train, fotmed of two Class 43 power cars and four Mark 3 carriages.

The V-Train 2 was a demonstration train designed in order to demonstrate our skills and expertise while bidding for the Intercity Express Programme project.

The page  is claiming, that a 20 % fuel saving could be possible.

This paragraph talks about performance.

The V-Train 2 looked to power the train away from the platform using batteries – which would in turn be topped up by regenerative braking when a train slowed down to stop at a station. Acceleration would be quicker and diesel saved for the cruising part of the journey.

A similar arrangement to that Hitachi produced in 2005 could be ideal.

  • Technology has moved on significantly in the intervening years.
  • The performance would be adequate for a train that just trundles around the West Country at 90 mph.
  • The space in the rear of the power car could hold a lot of batteries.
  • The power car would be quiet and emission-free in stations.
  • There would be nothing to stop the diesel engine running on biodiesel.

This might be the sort of project, that Hitachi’s partner in the Regional Battery Train; Hyperdrive Innovation. would probably be capable of undertaking.

MTU Hybrid PowerPack

I wouldn’t be surprised to find, that MTU have a drop-in solution for the current 6V4000 R41R diesel engine, that includes a significant amount of batteries.

This must be a serious possibility.

Rolls-Royce’s 2.5 MW Generator

In Our Sustainability Journey, I talk about rail applications of Rolls-Royce’s 2.5 MW generator, that has been developed to provide power for electric flight.

In the post, I discuss fitting the generator into a Class 43 power car and running it on aviation biofuel.

I conclude the section with this.

It should also be noted, that more-efficient and less-polluting MTU engines were fitted in Class 43s from 2005, so as MTU is now part of Rolls-Royce, I suspect that Rolls-Royce have access to all the drawings and engineers notes, if not the engineers themselves

But it would be more about publicity for future sales around the world, with headlines like.

Iconic UK Diesel Passenger Trains To Receive Green Roll-Royce Jet Power!

COVID-19 has given Rolls-Royce’s aviation business a real hammering, so perhaps they can open up a new revenue stream by replacing the engines of diesel locomotives,

I find this an intriguing possibility. Especially, if it were to be fitted with a battery pack.

Answering My Original Question

In answering my original question, I feel that there could be several ways to reduce the carbon footprint of a Class 43 power car.

It should also be noted that other operators are users of Class 43 power cars.

  • ScotRail – 56
  • CrossCountry – 12
  • East Midlands Railway – 39
  • Network Rail – 3

Note.

  1. ScotRail’s use of the power cars, is very similar to that of GWR.
  2. CrossCountry’s routes would need a lot of reorganisation to be run by say Hitachi’s Regional Battery Train.
  3. East Midlands Railway are replacing their Inter-City 125s with new Class 810 trains.

The picture shows the power car of Network Rail’s New Measurement Train.

These may well be the most difficult to decarbonise, as I suspect they need to run at 125 mph on some routes, which do not have electrification and there are no 125 mph self-powered locomotives. After the Stonehaven crash, there may be more tests to do and a second train may be needed by Network Rail.

Why Are GWR Increasing Their Castle Class Fleet?

These are possible reasons.

GWR Want To Increase Services

This is the obvious explanation, as more services will need more trains.

GWR Want To Update The Fleet

There may be something that they need to do to all the fleet, so having a few extra trains would enable them to update the trains without cutting services.

GWR Want To Partially Or Fully Decarbonise The Power Cars

As with updating the fleet,  extra power cars would help, as they could be modified first and then given a thorough testing before entering passenger service.

GWR Have Been Made An Offer They Can’t Refuse

Suppose Rolls-Royce, MTU or another locomotive power plant manufacturer has a novel idea, they want to test.

Over the years, train operating companies have often tested modified trains and locomotives for manufacturers.

So has a manufacturer, asked GWR to test something in main line service?

Are Other Train Operators Thinking Of Using Introducing More Short-Formed InterCity 125 Trains?

This question has to be asked, as I feel there could be routes, that would be suitable for a net-zero carbon version of a train, like a GWR Castle or a ScotRail Inter7City.

Northern Trains

Northern Trains is now run by the Department for Transport and has surely the most suitable route in the UK for a shorted-formed InterCity 125 train – Leeds and Carlisle via the Settle and Carlisle Line.

Northern Trains may have other routes.

Transport for Wales Rail Services

Transport for Wales Rail Services already run services between Cardiff Central and Holyhead using diesel locomotive hauled services and long distance services between South Wales and Manchester using diesel multiple units.

Would an iconic lower-carbon train be a better way of providing some services and attract more visitors to the Principality?

Conclusion

GWR must have a plan, but there are few clues to what it is.

The fact that the trains have been purchased rather than leased could be significant and suggests to me that because there is no leasing company involved to consult, GWR are going to do major experimental modifications to the trains.

They may be being paid, by someone like an established or new locomotive engine manufacturer.

It could also be part of a large government innovation and decarbonisation project.

My hunch says that as First Rail Holdings appear to be going for a lower-carbon fleet, that it is about decarbonising the Class 43 power cars.

The plan would be something like this.

  • Update the three new trains to the new specification.
  • Give them a good testing, before certifying them for service.
  • Check them out in passenger service.
  • Update all the trains.

The three extra trains would give flexibility and mean that there would always be enough trains for a full service.

Which Methods Could Be Used To Reduce The Carbon Footprint Of The Class 43 Power Cars?

These must be the front runners.

  • A Hitachi/Hyperdrive Innovation specialist battery pack.
  • An MTU Hybrid PowerPack.
  • A Rolls-Royce MTU solution based on the Rolls-Royce 2.5 MW generator with batteries.

All would appear to be viable solutions.

Stevenage Station’s New Fifth Platform Opened A Year Early

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

This is the introductory paragraph.

A new £40 million platform and track at Stevenage station has been completed more than a year ahead of schedule.

Yesterday, it appears that the first scheduled train left Stevenage for Moorgate at 0502.

Will This Be Good For Travellers?

A few thoughts!

Stevenage Hospital

One of my old school friends lives in Cuffley. From that part of Hertfordshire, the hospital, patients use is in Stevenage. He can drive, but not everybody can!

LNER

Currently, LNER run an hourly service between Stevenage and Leeds, with an hourly service between Stevenage and Lincoln or York via Newark.

North From Enfield, Palmers Green, Southgate, Winchmore Hill and Wood Green

If you live in Enfield or the old London boroughs of Southgate or Wood Green, it could be easier to pick up trains for the North from Stevenage, rather than Kings Cross.

Not Bad For Me Too!

Even, where I live now, which is a mile or so East of Highbury & Islington station, if the timing is right, I can walk or get a bus for four stops to Essex Road station and get a train to Stevenage and then change for Leeds and the North.

East Coast Trains

East Coast Trains will be starting a fast, low-cost London Kings Cross and Edinburgh service, which will call at Stevenage.

Grand Central Trains

Grand Central Trains are currently shut down because of COVID-19, but will they call at Stevenage station, when they restart?

Hull Trains

Some Hull Trains services between London Kings Cross and Hull, call at Stevenage.

Hitachi’s Class 80x Trains

LNER, East Coast Trains and Hull Trains, all run versions of Hitachi’s Class 800 trains or similar.

These trains are built for performance and an extra stop at Stevenage station can probably be incorporated in the timetable without any penalty.

So will we see more trains stopping at Stevenage, if the train operators think it will be worthwhile?

Could Some Services From The North Terminate At Stevenage?

The Digswell Viaduct and the double-track section through Welwyn North station are the major bottleneck on the East Coast Main Line.

But a train returning North at Stevenage wouldn’t go over the viaduct.

Stevenage already has or could have excellent connections to the following.

  • Cambridge, Stansted Airport and East Anglia
  • Moorgate and the City of London and Crossrail.
  • North East London

If keen pricing can encourage travellers to use Stevenage instead of Kings Cross, I can see operators wanting to run extra services, that could start at Stevenage.

I can also see Greater Anglia getting in on the act.

Could Greater Anglia’s Ipswich and Cambridge service be extended to Stevenage via the planned Cambridge South and Royston stations?

Could the service be timed to offer cross-platform interchange with their Norwich and Stansted Airport, at Cambridge South station?

Four important extra services would be created with a step-free interchange.

  • Ipswich and Stansted Airport – 106 minutes – Step-free walk across at Cambridge South station
  • Ipswich and Stevenage – 115 minutes – New direct service
  • Norwich and Stansted Airport – 107 minutes – Existing service
  • Norwich and Stevenage – 116 minutes – Step-free walk across at Cambridge South station.

A large number East Anglian rail journeys would be simpler.

Car Parking

Will there be enough car parking at Stevenage station?

I suppose, it would be possible to build a Stevenage Parkway station between Stevenage and Watton-at-Stone stations.

This Google Map shows the area.

Note, that the railway seems to mark the development limit for the town.

The high performance of the Class 717 trains, would probably mean, that there would be no lengthened journey times.

Conclusion

This project appears to have been well-thought through!

Westbury Station – 30th July 2020

I went to Westbury station today and took these pictures.

I found Westbury station to be a station in extremely good condition.

It also had a buffet, where I was able to purchase a delicious ice cream.

Passenger Services Through Westbury Station

I was at the station for about an hour and several trains passed through.

Great Western Railway services through the station include.

  • One train per two hour (tp2h) – London Paddington and Exeter St. Davids – Stops
  • One tp2h – London Paddington and Penzance – Passes through
  • One tp2h – London Paddington and Plymouth – Passes through
  • One train per hour (tph) – Cardiff Central and Portsmouth Harbour – Stops
  • One tp2h – Great Malvern and Westbury
  • One tp2h – Gloucester and Weymouth – Stops
  • One tp2h – Swindon and Westbury

Train classes included Class 800 trains and Class 166 trains.

South Western Railway services through the station include.

  • Five trains per day – Salisbury and Bristol Temple Meads – Stops

Train classes include Class 159 trains.

Battery Trains Through Westbury

Hitachi’s Class 800 train with a battery electric capability or Regional Battery Train, is described in this infographic from the company.

The proposed 90 km or 56 mile range could even be sufficient take a train between Westbury and Bristol Temple Meads stations on a return trip.

Many of the trains through Westbury go to the same stations.

Distances are as follows.

  • Bristol Temple Meads – 28 miles
  • Newbury – 42 miles
  • Salisbury – 24 miles
  • Swindon – 32.5 miles
  • Taunton – 47 miles

It looks like all of these places should be in range of an electric train with a battery capability, providing there is a charging facility at the other end.

An Electrification Island At Westbury Station

I have been advocating an island of electrification around Westbury station for some time and feel about a dozen miles of electrification through the station would be sufficient for Class 800 trains with a battery capability to bridge the gap.

  • At Newbury, trains would access the current electrification into London Paddington.
  • Between Exeter and Taunton, the rail route runs alongside the M5, so why not electrify this stretch, as the wires will not be so noticeable?

Looking at Westbury, to my untrained eye, it would appear that a short section of electrification around the station, would not be the most challenging of projects.

I believe that discontinuous electrification between Newbury and Exeter would be possible and could gradually be extended across Devon and Cornwall.

It should also be noted that one of Hitachi’s Regional Battery Trains has a range of 56 miles, so that these places from Westbury could be an return trip on batteries, with a well-driven train with excellent energy management.

  • Bath Spa – 17 miles
  • Bradford-on-Avon – 7 miles
  • Bristol Temple Meads – 28 miles
  • Chippenham – 16 miles
  • Frome – 6 miles
  • Salisbury – 24 miles
  • Trowbridge – 4 miles
  • Warminster – 9 miles

Obviously, the number of stops and the terrain will play a part.

Freight Might Drive Full Electrification Through Westbury Station

As the pictures show, there are heavy freight trains going through the area, which bring long and weighty loads of stone from the Mendips to London.

  • There are regularly two or three stone trains in an average hour of the day.
  • Like in the picture, I suspect they are usually hauled by a noisy, smelly, polluting and carbon-dioxide emitting Class 66 Locomotive. Not all of these, are as clean and well-maintained, as the one in the picture.
  • Some trains start at Merehead Quarry, which is about fifteen miles from Westbury station.

I believe that we must decarbonise freight trains.

But freight and electric haulage is not a simple subject.

  • I once had extensive talks with a Senior Crane Driver at the Port of Felixstowe during an Ipswich Town Away match. Ports don’t like overhead wires, as containers do get dropped and fall off rail wagons.
  • Suppose a historic line without electrification, like the Settle and Carlisle has a serious land-slip, which it did a couple of years ago. How do you haul in the materials for repair?
  • Because freight can be of a random and unpredictable nature, to electrify freight, you probably need to electrify the whole rail network.

For these and other reasons, we need independently-powered freight locomotives and I feel that a new freight locomotive will develop, that will be needed by the rail industry all over the world.

There are several solutions.

Biodiesel

Biodiesel is the simplest solution and would mean that the current diesel locomotives could be used.

In Grant Shapps Announcement On Friday, I talked about Government support for an industrial process, that has been developed by Oxford University and their spin-off company; Velocys, from the the Fischer-Tropsch Process, which can produce, the following fuels from household and industrial waste.

  • Aviation biofuel.
  • Biodiesel.

A plant to process 500,000 tonnes per year of Lincolnshire finest waste is now being built at Immingham to create 50,000,000 litres of fuel, by Altalto, which is a partnership between Velocys, British Airways and Shell.

If nothing else, waste-to-fuel is the interim solution to the decarbonisation of tricky sectors like heavy rail freight, rail construction, large diesel-powered machines, ships or long-distance aviation.

This fuel could be ideal to haul the heavy stone trains from the Mendips.

Hydrogen

I did think, it would be hydrogen powered, but I’m not so sure now, as hydrogen trains and locomotives seem to have a slow development cycle.

Although, there is one factor, that might influence the use of hydrogen as a fuel, which I wrote about in Thirsty High-Rollers … Mining’s Heavy Haulers Prime Candidates For Hydrogen Conversion.

Mining and quarrying don’t have a good green image, but converting mines and quarries to hydrogen power, would surely have operational and good public relational advantages.

It would also ensure a plentiful and convenient supply of hydrogen, for any hydrogen-powered locomotives.

Hydrogen-powered locomotives, with their electric transmissions, would probably be able to use electrification for traction power, so they would put pressure on the Government to electrify between Westbury and Newbury stations, so that there was a fully-electrified route between the Mendips and London.

Rolls-Royce’s Staggering Development

Staggering is not my word, but that of Paul Stein, who is Rolls-Royce’s Chief Technology Officer.

He used the word in a press release, which I discuss in Our Sustainability Journey.

To electrify aviation, Rolls-Royce has developed a 2.5 MW generator, based on a small gas-turbine engine, which Paul Stein describes like this.

Amongst the many great achievements from E-Fan X has been the generator – about the same size as a beer keg – but producing a staggering 2.5 MW. That’s enough power to supply 2,500 homes and fully represents the pioneering spirit on this project.

This generator is designed for flight and the data sheet for the gas-turbine engine is available on the Internet.

  • It has a weight of under a couple of tonnes compared to the thirteen tonnes of the diesel engine and generator in a Class 68 locomotive.
  • It is also more powerful than the diesel.
  • It looks to be as frugal, if not more so!
  • Rolls-Royce haven’t said if this gas-turbine can run on aviation biofuel, but as many of Rolls-Royce’s large engines can, I would be very surprised if it couldn’t!

Rolls-Royce’s German subsidiary is a large producer of rail and maritime diesel engines, so the company has the expertise to customise the generator for rail applications.

I can see this generator ending up in a high-powered heavy independently-powered electric locomotive for hauling stone and inter-modal container trains.

As with hydrogen-powered locomotives, this new breed of gas-turbine locomotive with its electric transmission, will be able to use electrification, where it exists.

So would locomotive developments drive the electrification through Westbury and especially between Westbury and Newbury?

I would rate is likely, that in the future, increasingly rail locomotives will have sophisticated electric transmissions, between their prime motive power of diesel, hydrogen, gas-turbine or whatever and their traction system. All of these locomotives will have pantographs and/or third-rail shoes to access electrification, where it exists.

These locomotives will surely add to pressure to electrify between Westbury and Newbury.

Biodiesel is surely the interim freight solution, if one is needed.

Future Zero-Carbon Passenger Services

Passenger services through Westbury can be divided into three groups.

Great Western Railway’s Services Between London Paddington And Devon And Cornwall

From Beeching Reversal projects put forward over the last few months, it looks like these services will increase and stop at several new and refurbished stations.

I can see discontinuous electrification being used to create a series of electrification islands to allow Class 800 trains, with a battery capability reach the Far South West of Cornwall.

Electrification islands could be at places like

  • Around Westbury station.
  • Between Taunton and Exeter St. Davids stations alongside the M5.
  • Between Plymouth station and the Royal Albert bridge.
  • Around Bodmin Parkway station
  • Around Truro station
  • At Newquay station
  • At Penzance station

Obviously, the number and type of the various installations will depend on the methods used and the engineering required.

I do believe that with Hitachi trains, that meet their specification, that trains will be able to travel between Paddington and Penzance without touching a drop of diesel.

Great Western Railway’s Cardiff Central And Portsmouth Harbour Service

The service can be split into the following legs.

  • Cardiff Central and Filton Junction – 33 miles – Electrified
  • Filton Junction and Bristol Temple Meads – 5 miles – Not Electrified
  • Bristol Temple Meads and Westbury – 28 miles – Not Electrified
  • Westbury and Salisbury – 24 miles – Not Electrified
  • Salisbury and Southampton Central – 15 miles – Not Electrified
  • Southampton Central and Portsmouth Harbour – 26 miles – Electrified

It would appear that a train with the performance and range on batteries of Hitachi’s Regional Battery Train should be able to handle the route, provided the following conditions are met.

  • It can leave the Great Western Main Line at Filton Junction with a full battery.
  • It can leave the electrification at Westbury station with a full battery.
  • It can leave Southampton Central station with a full battery.
  • Third-rail shoes are fitted for working between Southampton Central and Portsmouth Harbour stations.

Recharging batteries at Bristol Temple Meads and Salisbury stations, although probably welcome, are not necessary.

I can envisage Hitachi Class 800 and Class 385 trains being able to fulfil this role, along with Bombardier Electrostars and Aventras and Siemens Desiros.

As Great Western Railway have forty-five Class 387 trains, conversion of some of these to battery electric operation must be a possibility.

Great Western Railway’s Gloucester and Weymouth Service

The service can be split into the following legs.

  • Gloucester and Bristol Temple Meads – 39 miles – Not Electrified
  • Bristol Temple Meads and Westbury – 28 miles – Not Electrifield
  • Westbury and Dorchester Junction – 52 miles – Not Electrified
  • Dorchester Junction and Weymouth – 4 miles – Electrified

It would appear that a train with the performance and range on batteries of Hitachi’s Regional Battery Train should be able to handle the route, provided the following conditions are met.

  • It can leave Gloucester station with a full battery.
  • It can leave Bristol Temple Meads with a full battery.
  • It can leave Westbury with a full battery.
  • It can leave the South Western Main Line at Dorchester Junction with a full battery.

It would be a tight trip for a battery electric train and I suspect, that there would be some extra electrification between Westbury and Dorchester Junction or perhaps charging facilities at Frome or Yeovil Pen Mill stations.

The alternative would be to fit larger batteries on the train.

As to the train to be used, a Class 387 train with a battery capability would surely be ideal.

Great Western Railway’s Swindon and Westbury Service

The service can be split into the following legs.

  • Swindon and Chippenham – 16 miles – Electrified
  • Chippenham and Westbury- 16 miles – Not Electrified

It would appear that a train with the performance and range on batteries of Hitachi’s Regional Battery Train should be able to handle the route, provided the following conditions are met.

  • It can leave Chippenham station with a full battery.

This would have sufficient charge to do the thirty-two mile round trip from Chippenham to Westbury and back.

As to the train to be used, a Class 387 train with a battery capability would surely be ideal.

South Western Railway’s Bristol Temple Meads and Salisbury Service

The service can be split into the following legs.

  • Bristol Temple Meads and Westbury – 28 miles – Not Electrified
  • Westbury and Salisbury- 24 miles – Not Electrified

t would appear that a train with the performance and range on batteries of Hitachi’s Regional Battery Train should be able to handle the route, provided the following conditions are met.

  • It can leave Bristol Temple Meads station with a full battery.
  • It can leave Westbury with a full battery.
  • It can leave Salisbury with a full battery.

But, I do wonder, if with a slightly larger battery, a well-driven train could work the route with only charging the battery at Westbury station?

Conclusion

Could Westbury station develop into a zero-carbon rail transport hub for Wiltshire?

  1. It has an hourly train service between London Paddington and Exeter St. Davids.
  2. It has an hourly service between Bristol Temple Meads and Weymouth.
  3. There are hourly services to stations like Bath Spa, Bradford-on-Avon, Bristol Temple Meads, Chippenham, Dorchester, Frome, Swindon, Taunton, Trowbridge and Yeovil

It could be electrified to charge battery electric trains as they pass through.
