UK’s First Battery-Powered Trains Hit The Tracks
The title of this post, is the same as that of this article on the BBC.
This is the sub-heading.
The UK’s first battery-powered passenger trains have started running on Merseyside.
These two paragraphs outline the article.
The trains, which are part of the Liverpool City Region’s £500m publicly owned fleet, will run from the new £80m Headbolt Lane station in Kirkby.
Metro Mayor Steve Rotheram said the move helps to pave the way “for cleaner and greener” transport.
I particularly liked this paragraph.
The battery technology – which removes the need for a live third rail – could see the Merseyrail network running to previously inaccessible places, including Manchester, Wrexham, Warrington, Preston and Runcorn, according to a Liverpool City Region Combined Authority spokesperson.
After the trouble, I had on Tuesday, when I tried to get from Manchester to Saint Helens, Manchester is also a city that’s difficult to leave.
Improving Trains Between London And Bradford
Current Services Between London And Bradford
LNER services run between Kings Cross and Bradford Forster Square stations.
- Two trains per day (tpd) run between Bradford and London in the early morning.
- Two tpd run between London and Bradford in the evening.
- Trains take two and three-quarter hours.
- Stops are at Shipley, Leeds, Wakefield Westgate, Doncaster, Retford Grantham and Stevenage.
- Trains seem to be generally a pair of five-car Class 801 trains.
Note.
- Trains reverse at Leeds.
- The timetable seems a bit lopsided, as there is no early morning train to Bradford or an evening one to London.
- Harrogate gets a one train per two hours (tp2h) service to and from London.
The timetable could do with an improvement.
Grand Central services run between Kings Cross and Bradford Interchange stations.
- Four tpd run between Bradford and London.
- Four tpd run between London and Bradford.
- Trains take three and a quarter hours.
- Stops are at Pontefract Monkhill, Wakefield Kirkgate, Mirfield, Brighouse, Halifax and Low Moor
- Trains are five-car Class 180 trains, which have seen better days.
Note.
- The timetable seems a bit lopsided, as there is no early morning train to Bradford or an evening one to London.
The timetable and the trains could do with an improvement.
LNER’s New Ticketing And Nine-Ten Car Trains
LNER have introduced the selling of Advanced Tickets from machines or the Booking Office as late as five minutes before the train leaves.
- My last three trips from Leeds to London cost me £33.55, £33.75 and £33.55 with my Senior Railcard.
- All were bought less than ten minutes before the train left.
- In two of the journeys, I spread out in two seats
- Trains were either a pair of five-car Class 801 trains or a nine-car InterCity 225.
I took these pictures after my last return from Leeds on Tuesday.
Note.
- Two of the three trains I’ve taken lately have arrived 3-4 minutes early.
- Not a great increase, but I do wonder if LNER are seeing what is possible with the new digital signalling.
- The British Rail era; InterCity 225 seems to hold its own against the new Hitachi train.
I wouldn’t be surprised that LNER intend to both run high-capacity trains between London and Leeds and fill them by competitive pricing.
A Grand Central Train Failure On Tuesday
This was my journey to Bradford on Tuesday,
- I was supposed to take the 1057 Grand Central service to Bradford Interchange, where it was timed to arrive at 1400.
- But the train didn’t run and we were all advised to get on the 1103 to Leeds and change at Doncaster.
- We arrived at Doncaster in Platform 4, a minute late at 1240 and got straight on a Grand Central train in the opposite Platform 6.
- We left Doncaster at 1251, which was sixteen minutes late.
- But we arrived in Bradford Interchange more or less on time at 1401.
Despite leaving six minutes late from Kings Cross and changing trains at Doncaster, we arrived at Bradford on time.
Battery-Electric Trains Between London and Bradford Interchange
I feel that my journey on Tuesday indicated.
- Electric trains between London and Doncaster can easily meet the current timetable.
- The Grand Central train went between Doncaster and Bradford Interchange was sixteen minutes faster than the timetable.
I wouldn’t be surprised that London and Bradford Interchange could be a few minutes under three hours.
Consider.
- It has been said that between Bradford Interchange and Leeds will be electrified.
- Bradford Interchange and Doncaster does not have electrification, but is only 52 miles.
- Electrification of Bradford Interchange station, will allow battery-electric trains to be charged in around 10-12 minutes.
- Most inter-city battery-electric trains have a battery range of at least eighty miles.
- Digital signalling is being installed between London and Doncaster to allow 140 mph running and more trains in the timetable.
I believe that a battery-electric train with sufficient range, charging South of Doncaster and at Bradford Interchange could go between London and Bradford Interchange in 5-10 minutes under three hours.
Bradford Interchange and all the other stations North of Doncaster on the route could probably also have a one tp2h service to and from London and the South.
Splitting And Joining Of Trains
Consider.
- Pairs of the Hitachi Class 801 trains have the ability to split and join en route, during a station stop extended by a few minutes.
- Platforms are long enough to handle splitting and joining at Doncaster, Leeds and York.
- Currently, three services to and from London go past Leeds; Bradford Forster Square, Harrogate and Skipton. All these services reverse in Leeds station, when they pass through.
- The reversing in Leeds station takes about 8-9 minutes.
- The track between Leeds and Bradford Forster Square is electrified.
- Leeds and Harrogate is not electrified and is 19.3 miles.
- The track between Leeds and Skipton is electrified.
- Bradford Forster Square has a service of two tpd.
- Harrogate has a service of one tp2h.
- Skipton has a service of one tpd.
In the Wikipedia entry for LNER, this is said.
From December 2019, LNER introduced a Harrogate to London service six times a day. LNER expected to introduce two-hourly services to Bradford and a daily service to Huddersfield by May 2020 when more Azuma trains had been introduced, however the latter has not yet been introduced.
Note.
- The Huddersfield service would have to reverse in Leeds station, like those to Bradford Forster Square, Harrogate and Skipton.
- Leeds and Huddersfield is not electrified and is 17.1 miles.
- Leeds and Huddersfield is being electrified.
Could LNER’s plan be to give Bradford Forster Square, Harrogate, Huddersfield and Skipton stations a two-hourly service , as the Wikipedia extract indicated, they intend to do for Bradford?
- All trains enter and leave Leeds to and from the West.
- Pairs of five-car trains would split and join at Leeds.
- Bradford Forster Square and Skipton services would be served by electric trains.
- Harrogate and Huddersfield services would be served by bi-mode or battery-electric trains.
- Horsforth, Keighley and Shipley could also get a one tp2h service to London.
It looks like services via Leeds could be much improved.
In a two-hour period the Leeds area will have the following trains to and from London Kings Cross.
- Two trains between London and Leeds via Peterborough, Doncaster and Wakefield Westgate
- One train between London and Bradford Forster Square via Stevenage, Grantham, Retford (Bradford-bound only), Doncaster, Wakefield Westgate, Leeds and Shipley.
- One train between London and Harrogate via Stevenage, Grantham, Doncaster, Wakefield Westgate, Leeds and Horsforth
- One train between London and Huddersfield via Stevenage, Grantham, Doncaster, Wakefield Westgate and Leeds
- One train between London and Skipton via Peterborough, Newark Northgate, Doncaster, Wakefield Westgate, Leeds, Shipley (London-bound only) and Keighley.
Note.
- Stops between London and Leeds would be adjusted to satisfy passenger numbers.
- Currently, there are a total of four trains in a two hour period.
- Six trains will be fitted in by having two London and Leeds trains and two pairs of five-car trains, that joined and split at Leeds.
There is still only four train paths needed in a two hour period between London and Leeds.
Digital Signalling Between London And Doncaster
The East Coast Digital Programme has its own web site, which gives this introduction to the programme.
The East Coast Digital Programme is delivering the next generation of train travel – creating a better performing East Coast Main Line for passengers and everyone else who uses and depends on it.
As part of the programme, traditional lineside signals will be removed and replaced with state-of the art digital signalling to improve the reliability of the train service.
The new technology continuously communicates with each train, providing signalling information directly to a computer screen in the driver’s cab. It boosts reliability, reduces carbon emissions and provides a more punctual service for customers.
In the first stage, digital signalling will be introduced on the Northern City Line, between Finsbury Park and Moorgate. It will then be progressively rolled out on the southern section of the East Coast Main Line (between London King’s Cross and the Stoke Tunnels, near Grantham).
It is expected that the first trains to operate on the East Coast Main Line using digital signalling technology will run in 2025, with all improvements expected to be completed by the end of the decade.
As a result of this programme, the East Coast Main Line will be GB’s first intercity mainline to be upgraded to digital. It lays the foundation for further improvements across the network, creating a more efficient railway fit for the future.
There is also a video.
Benefits of digital signalling will include.
- 140 mph running instead of 125 mph.
- An increase in the number of train paths.
- Trains will be able to be run closer together.
As a Graduate Control Engineer, I also believe that digital signalling will enable better control of trains through bottlenecks.
- Could ERTMS And ETCS Solve The Newark Crossing Problem?
- Is There An ERTMS-based Solution To The Digswell Viaduct?
A computer solution would surely be more affordable than some massive civil engineering.
What Will Be The Fastest Times Possible Between London King’s Cross And Leeds?
I put my thoughts in What Will Be The Fastest Times Possible Between London King’s Cross And Leeds?.
Conclusion
The original High Speed Two specification gave a time of one hour and twenty-one minutes between Euston and Leeds.
I suspect that time will be approached before 2040.
Alstom And VMS Present New Battery-Powered Train
The title of this post, is the same as that of this article on Rail Technology Magazine.
This is the sub-heading.
Alstom and the Central Saxony transport authority, Verkehrsverbund Mittelsachsen (VMS) in Germany have unveiled a new battery-powered train developed by Alstom.
These first four paragraphs are very information rich.
A total of eleven Coradia Continental battery-electric trains have been ordered by VMS. These trains will enter service in 2024 on the Chemnitz-Leipzig line.
The Coradia Continental battery-electric train has a range of up to 120 kilometres and can be operated under catenary as well as on non-electrified sections of line. The three-car trains are 56 metres long and can seat up to 150.
The new train can also reach maximum speeds of 160 km/h in battery mode. The capacity of the high-performance lithium-ion batteries is calculated to guarantee catenary-free operation on the Chemnitz-Leipzig line without sacrificing performance.
Müslüm Yakisan, president of Alstom Region DACH, said: “Alstom’s ambition is to be the global leader in sustainable mobility, reducing emissions and pollution in catenary-free operation. The presentation of the first battery-powered train developed by Alstom is an important step in this direction.
These seem to be a very useful battery-electric train.
- Battery or catenary operation
- Three-cars of 19 metres
- Fifty seats per car
- 100 miles per hour
A three-car Class 730 train has the following characteristics.
- three cars of 20 metres
- 199 seats.
- 90 miles per hour
Can we have a battery version soon? Please!
Chiltern Sets Out New Fleet Ambitions
The title of this post is the same as that of an article in the September 2023 Edition of Modern Railways.
These are the first three paragraphs.
Chiltern Railways deserves to be the next operator to order new trains, its Managing Director Richard Allan has told Modern Railways.
On 7 August the operator published a tender notice seeking proposals for the supply of between 20 and 70 new or converted low-emission trains. This followed the unveiling on 19 July of its ‘RightRoute’ vision setting out the case for investment in new trains, which was presented to stakeholders and parliamentarians in Westminster.
Chiltern is prioritising replacement of its Class 165 DMU fleet, which comprises 89 vehicles. It carried out a pre-market engagement exercise last Autumn, and Mr. Allan said the view is that a battery train would be suitable for the Marylebone to Aylesbury route, either operating solely on battery power or additionally picking up power from the London Underground four-rail system South of Amersham.
These are my thoughts.
Electrification At Amersham
This OpenRailwayMap shows the electrification at Amersham station.
Note.
- Tracks shown in pink are electrified with the London Underground four-rail system.
- Tracks shown in black are not electrified.
- All three platforms are electrified.
The track layout allows both Chiltern and London Underground trains to pass through Amersham station on electrified lines.
Electrification Between Amersham And Harrow-on-the-Hill
This OpenRailwayMap shows the electrification at Northwood station.
Note.
- Tracks shown in pink are electrified with the London Underground four-rail system.
- All four platforms are electrified.
- Some sections are only double-track.
All tracks between Amersham And Harrow-on-the-Hill stations are electrified.
Electrification At Harrow-on-the-Hill
This OpenRailwayMap shows the electrification at Harrow-on-the-Hill station.
Note.
- Tracks shown in pink are electrified with the London Underground four-rail system.
- Tracks shown in black are not electrified.
- All six platforms are electrified.
The track layout allows both Chiltern and London Underground trains to pass through Harrow-on-the-Hill station on electrified lines.
Electrification Between Harrow-on-the-Hill And Finchley Road
Willesden Green station is typical of the stations on this section
This OpenRailwayMap shows the electrification at Willesden Green station
Note.
- Tracks shown in pink are electrified with the London Underground four-rail system.
- Tracks shown in black are not electrified.
- The two tracks South of the station are the Chiltern tracks.
- All Chiltern Trains along this route use these two separate tracks, that are not electrified.
Stations with this layout include Northwick Park, Preston Road, Wembley Park, Neasden, Dollis Hill, Willesden Green, Kilburn and West Hampstead.
The Chiltern Tracks Alongside The Metropolitan Line
I took these pictures as I journeyed from West Hampstead to Harrow-on-the-Hill.
Note.
- The Chiltern Tracks are those farthest from the train without electrification.
- There also seemed a lot of graffiti, where the tracks weren’t electrified.
- Platforms 1 and 2 at Harrow-on-the-Hill station are electrified and used by Chiltern’s diesel trains.
Finding a Jubilee or Metropolitan Line train with clean enough windows for photography was difficult.
Distances Between Stations
These are the distances, times and electrification, between selected stations, between Marylebone and Aylesbury Vale Parkway.
- Marylebone and Harrow-on-the-Hill – 9.2 miles – 13 minutes – Not Electrified
- Harrow-on-the-Hill and Amersham – 14.3 miles – 24 minutes – Electrified
- Amersham and Aylesbury – 15.3 miles – 23 minutes – Not Electrified
- Aylesbury and Aylesbury Vale Parkway – 2.3 miles – 7 minutes – Not Electrified
Note.
- The 24 minutes between Harrow-on-the-Hill and Amersham, should be enough to fully-charge the batteries.
- Harrow-on-the-Hill to Marylebone and return is 18.5 miles.
- Amersham to Aylesbury Vale Parkway and return is 35.2 miles.
As Merseyrail’s Class 777 trains have achieved 83.9 miles on battery power, I am fairly sure that Marylebone and Aylesbury Vale Parkway could be achieved by a battery electric multiple unit, that has been designed for the route.
Rolling Stock
Bombardier built the Class 378 Electrostar train, so that it would run on the London Underground four-rail system to Richmond. so I’m sure that Alstom could build Aventras, that could use the Underground electrification.
I’m also sure that other UK trains manufacturers and suppliers like CAF, Hitachi, Siemens and Stadler have the expertise.
The article mentions between twenty and seventy trains. The number probably depends on the train length.
I think we’ll see some interesting bids.
Train Charging Issues
The main charging will be done between Harrow-on-the-Hill and Amersham using the London Underground four-rail system already installed for the Metropolitan trains between London and Amersham and Chesham.
As the electrification will be powering six trains per hour in both directions between Harrow-on-the-Hill and Amersham and charging the batteries on the Chiltern trains, I wouldn’t be surprised to find, that the power system will be uprated.
I also suspect, that the trains could have the ability to use 25 KVAC overhead electrification, as this could allow short lengths of electrification to be used to charge the trains at terminal stations.
Speed Issues
If you look at the speeds and times, you get the following.
- Current Chiltern Class 165 trains are 75 mph trains.
- Current Underground S Stock trains are 62 mph trains.
- Chiltern take 33 minutes between Amersham and Marylebone.
- Trains in both services run every half hour.
- There is also an every half hour service between Chesham and Aldgate, which means there are six trains per hour between Chalfont & Latimer and Harrow-on-the-Hill.
- I suspect Chiltern set the timetable, by going through first with the slower Amersham and Chesham services following.
- This means that if the new Chiltern trains are 100 mph trains, it shouldn’t make much difference to the operation of the trains.
But the faster Chiltern trains could knock eight minutes off the time between Amersham and Harrow-on-the-Hill stations.
In an ideal world, where TfL had more money, faster Underground trains would allow more services to the area.
Leamington Spa Services
Chiltern Railways run two local services from Leamington Spa station.
- One service goes to Stratford-on-Avon, which is a distance of 15.3 miles.
- The other service goes to Birmingham Moor Street, which is a distance of 22.7 miles.
- Both services are run by Class 165 diesel trains.
- Both services have a frequency of one train per two hours.
I suspect that these services could be run using battery-electric trains with charging at Leamington Spa.
Timescale
This is said about timescale.
Under the plans set out in its ‘RightRoute’ prospectus, Chiltern wants to agree scope and funding for new trains this year and launch the first new trains by 2027 between London and Aylesbury, and upgrade infrastructure and trains on the West Midlands route between 2028 and 2035.
West Midlands Route
This is said about the West Midlands route.
Mr Allan said that after ‘165’ replacement consideration would be given to the best solution for the main line between London and the West Midlands, including whether this would involve partial or full electrification, with a rolling stock solution to succeed the Class 168 DMUs and loco-hauled sets to be devised accordingly. Chiltern’s Interim Engineering & Safety Director Tim Sayer told Modern Railways one potential option the Government and Network Rail are keen on is third party funding of electrification, which could be built into a manufacturer’s contract for new stock.
Note.
- I must admit that I like the idea of bundling rolling stock and electrification in one contract.
- After all, rolling stock and maintenance have been bundled together for some years and it seems to work.
- I disclose some of Hitachi’s thinking in Solving The Electrification Conundrum, which is based on an article in Modern Railways.
I wonder if Hitachi will come up with a solution something like this.
- A number of five-car battery-electric trains.
- High quality interiors.
- They would serve Birmingham Moor Street, Oxford and Stratford-on-Avon.
- Short lengths of electrification in terminals and perhaps at strategic locations in the middle. Banbury?
- Automation as needed.
It could be a service that’s a viable alternative to High Speed Two for some passengers.
Charging At London Marylebone Station
I recently took these pictures at Marylebone station.
Note.
- It is a surprisingly spacious station and I feel that Furrer+Frey or some other specialist company could add some form of charging to the platforms.
- In its simplest form it would be a short length of 25 KVAC overhead electrification.
- Charging would be performed using the train’s pantograph.
It appears that the turnround time in Marylebone is typically twelve minutes or more, which should be adequate to fully charge a train.
Charging At Oxford Station
These pictures show the bay platforms at Oxford station, where Chiltern services terminate.
I wouldn’t be surprised, if these two platforms were designed for future 25 KVAC overhead electrification.
Marylebone And Oxford Services
Marylebone and Oxford are only 66.7 miles apart and I believe that a battery electric train would be able to shuttle between the two terminals, charging as required after each journey.
Charging At Birmingham
These pictures show the bay platforms at Birmingham Moor Street station, where some Chiltern services terminate.
Note.
- Currently, Birmingham Moor Street station has two through platforms and two bay platforms.
- None of the platforms are electrified.
- Some plans include adding two more bay platforms to the station.
- Electrifying the bay platforms 3 and 4, would allow the charging battery electric trains from London.
The two through platforms could also be electrified to help Birmingham’s local trains decarbonise and allow London services to reach Birmingham Snow Hill station.
Marylebone And Birmingham Services
Consider.
- Marylebone and Birmingham Moor Street are only 111.7 miles apart.
- Birmingham Moor Street and Birmingham Snow Hill stations are only 0.6 miles apart.
- Birmingham Moor Street and Birmingham Snow Hill stations could be easily connected by an electrified line.
- Stadler are talking of battery-electric trains having a range of over 125 miles.
- It might be sensible to electrify Banbury to give the batteries a top up.
I believe that a battery electric train would be able to shuttle between Marylebone and Birmingham, charging as required after each journey.
Conclusion
It seems a sound plan!
Morley Station – 17th August 2023
These pictures show Morley station, which is currently being upgraded.
I was rather surprised at the lack of any sign of electrification.
There was no sign of any gantries for overhead electrification, either installed or ready to installed.
In Is There Going To Be Full Electrification Between Leeds And Huddersfield?, I said this.
I have now found this document on the Network Rail web site, which is entitled Huddersfield to Westtown (Dewsbury).
This statement is included under proposals.
Electrification of the railway from Huddersfield to Ravensthorpe – and right through to Leeds.
Because there is a dash in the words, has electrification to Leeds, been a recent addition?
I also showed this map, that I have copied from the Network Rail document
Note the railway lines shown in red. Are these the ones to be electrified? As they go from Huddersfield to Westtown, I think the answer is probably in the affirmative.
Surely, if there were going to be electrification through Morley, they’d have at least put the gantries up by now or installed the bases for them by now?
These are some distances from Real Time Trains.
- Leeds and Morley – 4.6 miles
- Morley and Dewsbury – 5,5 miles
- Dewsbury and Huddersfield 8 miles
Note.
- Leeds and Dewsbury are only 10.1 miles apart, which would be an easy journey for a battery-electric train.
- Trains typically take eighteen minutes between Dewsbury and Huddersfield, which would surely be more than enough time to charge the batteries on a train.
- It also appears that the only trains through Morley station are passenger services run by TransPennine Express or Northern Trains.
It certainly looks to me, that the section of the route between Dewsbury and Leeds though Morley station is to be run using battery-electric trains.
Southeastern Keen On Battery EMUs
The title of this post, is the same as that of a small section in the August 2023 Edition of Modern Railways.
This is said.
Southeastern is to seek pre-qualification interest from manufacturers and leasing companies for a replacement fleet for the Networker Class 465 and 466 inner-suburban stock, now over 30 years old. The company intends to compare the price of new and cascaded stock.
Southeastern MD Steve White told Modern Railways his preference is for a bi-mode EMU, capable of working off both the third rail supply and batteries. Battery EMUs were originally proposed for the Networker replacements so they could work through services to the unelectrified Isle of Grain branch, after Medway Council put forward plans to restore passenger services on the Hoo peninsular to serve new housing there.
Despite the extension of services to Sharnal Street on the Isle of Grain having since been put on hold by Medway Council on cost grounds (p13, May issue).
Southeastern is still pursuing battery EMUs, even though the company’s existing network is all electrified on the third rail system.
Merseyrail is already adopting battery EMU technology, with seven of the new fleet of 53×4-car Class 777 units being equipped with batteries to enable them to serve the unelectrified extension to Headbolt Lane (p82, July 2022 issue).
Mr. White says there are a number of reasons battery EMUs are attractive.
-
- Increasing levels of mental health issues in society have led to trespass being a major issue the railway: battery EMUs would make it feasible to keep trains moving at slow speed when the current supply has to be switched off to protect a trespasser.
- Battery EMUs would be able to keep moving on occasions when the third rail supply fails, due to technical failures or ice on the conductor rail. This would avoid the compounding of problems, as when delayed passengers got out on the track at Lewisham in March 2018 when the third rail iced up, forcing Network Rail to cut the electricity supply and making it more difficult to get trains moving again.
- Battery EMUs would make it feasible to remove third rail from depots, making them safer places in which to work. A train cleaner was electrocuted and died at West Marina depot in St. Leonards in May 2014, and the Office of Road and Rail has well-publicised concerns on safety grounds about any extensions to the third rail system.
- Battery EMUs would be able to cater for service extensions on unelectrified lines, such as the Isle of Grain.
Mt. White says the trespass issue is the major driver, and if the principle of battery EMUs becomes established it might prove feasible to remove the third rail from platform areas at inner-suburban stations with a persistent trespass problem. He points out this approach might unlock extension of third rail to routes such as the Uckfield line, allowing station areas to be left unelectrified. Replacement of DMUs by electric stock on the Uckfield branch would eliminate diesel working at London Bridge, with air-quality and carbon removal benefits for the capital.
There are a 5-star hotel and a major hospital close to the diesel-worked plstform at London Bridge.
I will now look at some of the issues in detail.
Range Of A Battery EMU
I discuss range of battery EMUs in these posts.
- Stadler FLIRT Akku Battery Train Demonstrates 185km Range
- New Merseyrail Train Runs 135km On Battery
Note.
- Both trains are built by Stadler.
- 135 km. is 84 miles.
- A Bombardier engineer told me eight years ago, that the prototype battery-electric Class 379 train had a range of sixty miles.
I feel it is reasonable to assume that a 100 mph battery-electric train, designed to replace Southeastern’s Networkers could have a range of at least sixty miles.
Distances Of Cannon Street Metro Services
These are distances of services from Cannon Street.
- Erith Loop via Greenwich, Woolwich Arsenal and Bexleyheath – 28.5 miles
- Gravesend – 24.5 miles
- Orpington – 12.6 miles
- Grove Park – 7.1 miles
- Slade Green – 14.5 miles
Note.
- The Erith Loop services start and finish at Cannon Street station.
- The Gravesend service terminates in an electrified bay platform.
- The Orpington service terminates in an electrified bay platform.
- Grove Park and Slade Green are depots.
If trains could be fully charged at Cannon Street station, all services out of the station could be worked by a battery EMU with a range of forty miles.
Charging At Cannon Street
Consider.
- All Cannon Street services arrive at the station via London Bridge station.
- All Cannon Street services leave the station via London Bridge station.
- Trains typically take 4-5 minutes between Cannon Street and London Bridge station.
- Trains typically wait at least 7 minutes in Cannon Street station before leaving.
- Typically, a battery EMU takes fifteen minutes to charge.
A train running from London Bridge to London Bridge would probably take a minimum of fifteen minutes, which should be enough to charge the train.
The track between London Bridge and Cannon Street would need a strong level of protection from trespassers.
I suspect that with some slight timetable adjustments, all Cannon Street services could be run using battery EMUs.
Distances Of Charing Cross Metro Services
These are distances of services from Charing Cross.
- Maidstone East – 38.9 miles
- Dartford – 17.1 miles
- Gravesend – 23.8 miles
- Hayes – 14.3 miles
- Sevenoaks – 22.2 miles
- Grove Park – 8 miles
Note.
- The Gravesend service terminates in an electrified bay platform, which could be used to charge the train before return.
- The Maidstone East service terminates in an electrified platform.
- Grove Park is a depot.
If trains could be fully charged at Charing Cross station, all services out of the station could be worked by a battery EMU with a range of fifty miles.
Charging At Charing Cross
Consider.
- All Charing Cross services arrive at the station via London Bridge station.
- All Charing Cross services leave the station via London Bridge station.
- Trains typically take 10 minutes between Charing Cross and London Bridge station.
- Trains typically wait at least 7 minutes in Charing Cross station before leaving.
- Typically, a battery EMU takes fifteen minutes to charge.
A train running from London Bridge to London Bridge would probably take a minimum of twenty minutes, which should be enough to charge the train.
The track between London Bridge and Charing Cross would need a strong level of protection from trespassers.
I suspect that with some slight timetable adjustments, all Charing Cross services could be run using battery EMUs.
Distances Of Victoria Metro Services
These are distances of services from Victoria.
- Gillingham – 37.2 miles
- Orpington – 14.7 miles
- Dartford – 18.9 miles
Note.
- The Orpington service terminates in an electrified bay platform.
- The Gillingham service terminates in an electrified bay platform.
- The Dartford service terminates in an electrified platform.
If trains could be fully charged at Victoria station, all services out of the station could be worked by a battery EMU with a range of fifty miles.
Charging At Victoria
Consider.
- All Victoria services arrive at the station via Shepherds Lane junction.
- All Victoria services leave the station via Shepherds Lane junction.
- Trains typically take five minutes between Victoria and Shepherds Lane junction.
- Trains typically wait at least 7 minutes in Victoria station before leaving.
- Typically, a battery EMU takes fifteen minutes to charge.
A train running from Shepherds Lane junction to Shepherds Lane junction would probably take a minimum of seventeen minutes, which should be enough to charge the train.
The track between Shepherds Lane junction and Victoria would need a strong level of protection from trespassers.
Conclusion
It certainly appears that if the Networker Class 465 and Class 466 trains were replaced by new trains with the following specification.
- 100 mph operating speed.
- Range of fifty miles on battery power.
- Ability to charge batteries in fifteen minutes.
- Third-rail operation
- It might be an idea to add a pantograph, so the trains could use 25 KVAC overhead wires where necessary and charge batteries on a short length of overhead electrification.
Then a substantial part of the Southeastern Metro network could be made safer, by selective removal of third rail at trespassing hot spots.
Battery Train Deployment Report Commissioned
The title of this post, is the same as that of this article on Railway Gazette.
This is the first paragraph.
The Rail Safety & Standards Board has commissioned consultancy WSP to produce evidence-based recommendations for optimising and standardising the adoption of battery-powered trains.
Note.
- The train shown in the picture in the article is a Stadler FLIRT Akku.
- WSP are a well-respected Canadian engineering consultancy.
To commission a development report sounds to be a sensible act.
Electrification Between Newbury And East Somerset Junction
In the August 2023 Edition of Modern Railways, there is an article, which is entitled GWR Seeks Opportunities To Grow.
This is the sub-heading.
Managing Director Mark Hopwood tells Philip Sherratt there is plenty of potential to increase rail’s economic contribution.
This is two paragraphs.
The desire to provide electrification to support aggregates traffic from the Mendip quarries could also benefit GWR , says Mr. Hopwood. ‘Having an electric loco would massively help with pathing heavy freight trains through the Thames Valley. If you could electrify from Newbury to East Somerset Junction, a big chunk of the Berks and Hants route would be wired.
Then you can ask how much further you could get on battery power on an IET without running out of juice.’
I have some thoughts.
Where Is East Somerset Junction?
This OpenRailwayMap shows East Somerset junction.
Note.
- The East Somerset junction is marked with the blue arrow.
- East Somerset junction is 5.2 miles North of Bruton station and 5.4 miles South of Frome station on the Reading and Taunton Line.
As the map shows there is a branch to Merehead Rail Sidings, which is shown in yellow.
This Google Map shows Merehead Rail Sidings.
Note.
- It looks like there is a massive quarry to the North of the A361 road, which curves across the map.
- It is labelled Torr Works – Aggregate Industries.
- Torr Works has a Wikipedia entry.
- The rail sidings are South of the A361.
- Zooming in on the map, shows that the railway between East Somerset junction and Merehead is single-track and only a few miles long.
Distances from East Somerset junction are as follows.
- Dorchester junction – 41.2 miles
- Newbury – 53.4 miles
- Taunton – 37.2 miles
- Weymouth – 47.8 miles
Note that it is electrified with 750 VDC third-rail between Weymouth and Dorchester junction.
Range of Battery-Electric Trains
Consider.
- A Bombardier engineer told me eight years ago, that the battery-electric Class 379 train had a range of sixty miles.
- Stadler’s FLIRT Akku has a Guinness world record of 139 miles on one battery charge. See this page on the Stadler web site.
- Even Stadler’s Class 777 trains for Merseyrail have a range of 84 miles on battery power. See New Merseyrail Train Runs 135 km On Battery.
It does appear that five-car battery-electric trains will have ranges in excess of a hundred miles.
I believe that because Hitachi’s battery makers have a good record, they will probably be very ambitious and will want that Guinness record, that Hitachi’s Class 802 trains will have a battery range not far short of the 139 miles of the Stadler FLIRT Akku.
I will be very surprised if Hitachi’s battery-electric version of a Class 802 train, doesn’t have range of at least 125 miles.
But say if they could do say 140 miles, the battery-electric Class 802 train could cover every long-distance route in the UK, which would attract orders for trains to run on the following routes.
- Cardiff and Swansea
- Crewe and Holyhead
- Edinburgh and Aberdeen
- Edinburgh and Inverness
- Crewe and Holyhead
- London Waterloo and Exeter St. Davids
A substantial reward to the battery makers, would probably not be out of order.
Aggregate Trains From The Mendips
Consider.
- Mining and quarrying companies are under pressure from governments, shareholders and environmentalists to reduce their carbon footprints.
- Many are replacing diesel-powered mining excavators and trucks, with electric or hydrogen versions.
- In addition, those companies delivering building products to the construction industry are under pressure to provide low-carbon products.
- Using rail with electric traction to deliver products to market would cut carbon emissions and might even help sales.
These Mendip quarries appear to be connected to the Reading and Taunton Line.
- Torr Works – Connects 5.4 miles to the South of Frome.
- Whatley Quarry – Connects close to Frome.
There may be others.
But these rail-connected quarries, connect at or North of East Somerset junction, to where Mark Hopwood is proposing electrification.
Zero-carbon rail traction could even be possible, by electrifying the short single-track branch lines. or by using hydrogen-electric hybrid locomotives.
GWR’s London And South-West Services
These services use the Reading and Taunton Line to join the Bristol and Exeter Line at Taunton, before going on to Exeter, Plymouth and other destinations in the South-West of England.
These are distances from East Somerset Junction.
- Exeter – 67 miles
- Paignton 95.2 miles
- Penzance – 198.5 miles
- Plymouth – 119.0 miles
- Taunton – 37.2 miles
Note.
- Exeter, Paignton, Penzance and Plymouth stations would need short lengths of electrification to charge terminating trains or top-up passing trains.
- In Thoughts About Electrification Through Devon And Cornwall, I showed that the average stop time at Plymouth station was eight minutes, which could be enough for the rail equivalent of a Formula One splash and dash.
- A 125 mile battery range, not only enables London and Penzance, but also Cardiff and Swansea, and Edinburgh and Aberdeen, when the extra electrification is completed.
Could my estimate of a 125 mile battery range, be Hitachi’s objective for their battery-electric trains?
The Ultimate Battery-Electric Class 802 Train
Hitachi have been totally silent on how the fitting of batteries to Class 802 trains is going.
But Mark Hopwood is more forthcoming in the GWR Seeks Opportunities To Grow article. where this is said.
Meanwhile, GWR had announced plans with Eversholt Rail to trial the replacement of a diesel generator unit with batteries on a Class 802 IET. However, Mr. Hopwood says this would not be useful for GWR and so the trial is not proceeding; instead, a TransPennine Express Class 802 will be the subject of a battery trial.
It sounds to me that another solution is being developed to get trains to run on electric power between London and the South-West.
- I think we can rule out full electrification on the grounds of cost, disruption, time and the Nimbys and objectors will have a field day.
- Newbury and Penzance is a distance of 251.9 miles, which would surely need a lot of batteries.
Mark Hopwood’s idea to electrify the 53.4 miles between Newbury And East Somerset junction, is starting to look like a good compromise.
GWR’s Bristol/Gloucester And Weymouth Services

Note.
- I would assume that there is enough electrification at Bristol Temple Meads and towards Gloucester to charge the trains.
- Trains would leave Bristol Temple Meads with a full battery.
- The eighteen stops mean that an electric train with regenerative braking will be more efficient.
- Bristol Temple Meads and Westbury is not electrified.
- Westbury and East Somerset junction will be electrified with 25 KVAC overhead electrification under Mark Hopwood’s proposal.
- Trains take sixteen minutes between Westbury and East Somerset junction.
- East Somerset junction and Dorchester junction is not electrified.

- Chippenham and Westbury – 15.8 miles – Not Electrified
The section without electrification, should be well within range of a battery-electric train, that has been designed for the route.
What Can Be Done If The Electrification Is Not Long Enough?
Some of these routes battery-electric routes may need more electrification to work efficiently.
Despite some routes having both 25 KVAC overhead and 750 VDC third-rail electrification, any extension of the electrification would be overhead, as new third-rail electrification is effectively banned.
Conclusion
It looks like Mark Hopgood proposal is an excellent idea to enable the decarbonisation of GWR services in Wiltshire and Somerset.
- Express services would be run by battery-electric Class 802 trains.
- Local services would be run by battery-electric trains with perhaps three cars.
Some of the local trains would need to be dual-voltage to use both forms of electrification.
Centrica To Build Largest Battery Storage Project To Date
The title of this post, is the same as that of this news item from Centrica.
These three paragraphs outline the news.
Centrica Business Solutions has secured the development rights to a 65MW two-hour battery storage plant in Perthshire, Scotland, its largest battery storage acquisition to date.
The site in Abernethy is located near a connection for North Sea offshore wind farms and will help manage grid capacity by charging when demand for power is low, and discharging when demand is at its highest.
Once connected to the grid in 2028, the 65MW two-hour battery will be able to store enough electricity to power 130,000 homes for an hour – the equivalent to a town the size of Aberdeen. The discharge could happen up to four times a day.
This map shows the site of the substation at Abernethy.
It seems a site with enough space for a 65 MW/130 MWh battery.
But is that a railway running past the site in the South-East corner of the map?
Yes! It is the single-track unelectrified railway that is used by trains to go between Edinburgh and Perth.
- There are stations at both ends of the single-track section at Ladybank and Perth.
- Abernethy substation looks like it is about halfway between the two end stations.
This page on Scotland’s Railway is entitled Fife Electrification and lists these four phases.
- Haymarket and Dalmeny
- Kinghorn and Thornton North
- Thornton and Lochgelly
- Thorton and Ladybank
The page also says that the electrification will support BEMUs (Battery Electric Multiple Units)
I feel that the electrification to Ladybank and Centrica’s battery could be linked.
- If the electrification was extended a few miles to Abernethy substation, this would surely be a reliable way to power the electrification.
- It would also be ideally placed, if Perth and Ladybank were to be electrified.
- The new battery would surely smooth out any deviations in the power supply.
I certainly don’t expect that Centrica will object to a new customer.
Electrification Between Edinburgh And Ladybank
Consider.
- Edinburgh and Ladybank is 39 miles and takes a couple of minutes over an hour.
- Once, the four phases of the electrification are complete, only the 13.6 miles between Dalmeny and Kinghorn, will be without electrification.
- I doubt that Dalmeny and Kinghorn will ever be electrified, as it includes the Forth Rail Bridge.
- Dalmeny and Kinghorn is 13.6 miles and takes around twenty-four minutes.
It looks like the BEMUs will be under wires for 25.4 miles and nearly forty minutes, which will be more than enough to charge the trains.
Edinburgh And Aberdeen
In Thoughts On Batteries On A Hitachi Intercity Tri-Mode Battery Train, I said this about services between Edinburgh and Aberdeen.
Consider.
-
- The gap in the electrification is 130 miles between Edinburgh Haymarket and Aberdeen.
- There could be an intermediate charging station at Dundee.
- Charging would be needed at Aberdeen.
I think Hitachi could design a train for this route.
The 25.4 miles of new Fife electrification between Haymarket and Ladybank will reduce gap in the electrification to 105 miles and ensure trains leaving Ladybank for Aberdeen had a full battery.
Taunton To Exeter St. Davids – 4th July 2023
I took these pictures as I travelled from Taunton station to Exeter St.Davids station.
This Google Map shows a section of the M5 North of Collumpton.
Note.
- The proximity of the M5 motorway to the railway, in some pictures and the map.
- There is space to plant large numbers of trees between the motorway and the railway.
- There are high voltage overhead electrical cables running along the same corridor.
- Collumpton services are also placed between the motorway and the railway.
I believe that with good landscaping, it would be possible to improve the motorway and railway corridor, between Taunton and South of Collumpton.
This OpenRailwayMap shows the track between Wellington and Collumpton, between Taunton and Exeter.
Note.
- The black line is the railway between Taunton and Exeter.
- The blue arrow in the North-East corner of the map indicates the position of the proposed Wellington station.
- Collumpton is in the South-West corner of the map and has also been put forward for a new Collumpton station.
- I talked about the reopening of these two stations in Reopening Of Wellington and Cullompton Stations.
- The M5 to the North of Collumpton runs closely alongside the railway.
- According to Real Time Trains, it takes just under ten minutes to go the thirteen miles between Wellington and Cullompton.
I believe that by using partial electrification, good engineering and innovative landscaping, that sufficient electrification can be erected between Taunton and South of Collumpton, that would ensure the following.
- Trains would leave Taunton going East with enough charge to travel the 89.6 miles to Newbury.
- Trains would leave Taunton going North with enough charge to travel the 51.7 miles to Patchway via Western-super-Mare and Bristol Temple Meads.
- Trains would leave Cullompton going South with enough charge to travel the 32.9 miles to Okehampton.
- Trains would leave Cullompton going South with enough charge to travel the 36.6 miles to Paignton.
- Trains would leave Cullompton going South with enough charge to travel the 60.4 miles to Plymouth.
Note.
- I’ve added Okehampton, as I feel that if Dawlish had another encounter with Poseidon, Okehampton with its proposed Parkway station on the A30 could be the terminus for coaches to and from Cornwall.
- Charging could be needed at Okehampton and Paignton.
- Charging at Okehampton and Paignton, wouldn’t be needed, if the battery-electric trains had enough range to do the return trip.
Electrification of Plymouth and Penzance stations, as I outlined in Thoughts About Electrification Through Devon And Cornwall, would enable battery-electric trains to bridge the gap of 79.5 miles, between these two stations.
Conclusion
It looks like some miles of sympathetic electrification and landscaping between Taunton and South of Cullompton, is the key to running battery-electric train to Devon and Cornwall.
