Three New Battery-Only Revolution Very Light Rail Vehicles
This title of this post, is the same as that as this press release from Eversholt Rail Group.
These are the three bullet points.
- Eversholt Rail funding three brand-new Revolution Very Light Rail vehicles for passenger trials and ongoing operation.
- Manufactured in the UK by Transport Design International.
- Battery-only propulsion, providing zero-emissions operation.
These three paragraphs fill out the story.
Innovative new lightweight passenger trains that will help decarbonise Britain’s railways are to be trialled after a new deal was announced this week.
The new Revolution Very Light Rail vehicles will run entirely on battery power and could be carrying passengers within three years. A new system of lineside fast charging will mean the whole operation has zero emissions.
Some of Britain’s major rail operators are already showing interest in the RVLR vehicles as they seek to fulfil promises to make rail ‘cleaner’.
This is also said about looking for routes, to trial the new vehicles.
Eversholt Rail and TDI are working with key stakeholders across the UK rail industry to agree routes and services where operators can run passenger-carrying trials using these new vehicles. These trials will generate actual passenger demand data to support business cases for long-term deployment of RVLR vehicles as well as providing further passenger and operator feedback on their design and capabilities.
I have some thoughts and questions.
What Is The Top Speed?
A lot of questions like this are answered by this article on Rail Engineer, which is entitled Very Light Rail – A Revolution.
These can be ascertained from this comprehensive article.
- Top Speed – 65 mph
- Seats – 56
- Wheelchair space
- PRM TSI accessibility compatible
- Tare Weight – 24.8 tonnes
- USB Charging
For comparison these figures relate to a PRM-compliant Class 153 diesel train.
- Top Speed – 75 mph
- Seats – 59
- Tare Weight – 41.2 tonnes
This picture shows one of the Class 153 trains at Matlock Bath station.
There are still around thirty in service in the UK.
Can Two Revolution VLRs Run As A Two-Car Train?
From the pictures on the web, the trains have buffers and space for a coupler, so until someone says they must always run as single units, I’ll assume they can at least run as a pair.
Can A Revolution VLR Recharge Its Batteries Using Conventional 25 KVAC Overhead Electrification?
One route, that is a possibility for running using Revolution VLR must surely be the Greenford Branch, which connects to the electrified Great Western Main Line at West Ealing station.
In this and at several other places on the network, it could be easier to charge the trains using the existing overhead electrification or an extension of it.
Another possibility; the Marston Vale Line is also electrified at both Bedford and Bletchley.
In New Mobile Rail Charging Facility For Long Marston, I talked about how Siemens are developing a mobile charger, which initially will be deployed at Long Marston.
It could be very useful for efficient operation, if the batteries on a Revolution VLR could be charged in a number of places, which included conventional electrification.
If charging only happened, whilst trains were stationary, a lightweight pantograph and appropriate electrical gubbins might be sufficient.
Can A Revolution VLR Replace A Class 153 Train?
I suspect on some routes this will be possible, but on others, the speed or hill-climbing requirements might be too stiff for the lightweight train.
But, if I was designing a train like the Revolution VLR, I’d make sure it fitted as many markets as possible.
The picture was taken at Matlock Bath station on the Derwent Valley Line, which is a single track with a fifty mph limit and an uphill climb. I suspect that the Revolution VLR would be designed to handle the uphill part of the route, but would the train be able to handle the speed of the Midland Main Line to Derby.
The Revolution VLR would probably attract more passengers, so it might be necessary to double up the service by running a pair.
Can A Pair Of Revolution VLRs Replace A Class 150 Train?
I don’t see why not!
Could The West London Orbital Use Revolution VLRs?
This might be a proposed route that could use Revolution VLRs.
The two routes would be.
- West Hampstead and Hounslow.
- Hendon and Kew Bridge.
Both services would use the Dudding Hill Line and serve Neasden, Harlesden, Old Oak Common and Acton, with a frequency of four trains per hour (tph).
Although this service could be run using conventional multiple units, it might be more affordable to use Revolution VLRs charged on sections of line that are already electrified.
Could the Greenford Branch Use Revolution VLRs?
The Greenford Branch would be a classic application and trains could be charged by fitting a charger in the bay platform at West Ealing station.
In An Automated Shuttle Train On The Greenford Branch Line, I did a rough calculation to see if an automated shuttle could achieve four tph.
Four tph might be too ambitious, but automatic trains shuttling along a branch line might be an affordable way to provide zero-carbon trains with an adequate capacity.
- The driver would drive the train using the sort of remote control used for drones.
- The driver would sit in a convenient place on the train, with CCTV to help them see everything.
- When the train was ready to leave, the driver would push a button to tell the train to move to the next station.
- On arrival at the next station, the doors will open.
- The process would repeat along the line.
If this method of operation sounds vaguely familiar, the Victoria Line has used it since 1067.
Although the Victoria Line drivers always sit in the front.
But on a line with no other trains running at the same time, all they need is a good view of the doors.
Branch lines that could be run in this way could include.
Bodmin Parkway and Bodmin General
Brockenhurst and Lymington Pier
Grove Park and Bromley North
Lancaster and Morecambe
Liskeard and Looe
Lostwithiel and Powey
Maidenhead and Marlow
March and Wisbech
Par and Newquay
Plymouth and Gunnislake
Romford and Upminster
Sittingbourne and Sheerness-on-Sea
Slough and Windsor Central
Southall and Brentford
St. Erth and St. Ives
Truro and Falmouth Docks
Twyford and Henley-on-Thames
Watford Junction and St. Albans Abbey
West Ealing and Greenford
Wickford and Southminster
Wymondham and Dereham
Crafty Electrification On The Rhymney Line
I was puzzled on Wednesday, when I took the Class 231 train to Caerphilly on the Rhymney Line, when I saw no signs of electrification.
These are pictures I took at Caerphilly station.
These two OpenRailwayMaps show the tracks through Caerphilly.
Note.
- The map on the left shows infrastructure, with the Rhymney Line shown in yellow.
- Caerphilly station is in the top third of the map.
- The white section of the Rhymney Line is the Caerphilly tunnel.
- The map on the right shows electrification, with the sections of the Rhymney Line that will be electrified are shown in red.
- Black sections will not be electrified.
- North of Caerphilly, the Rhymney Line is electrified, but through the station and the Caerphilly tunnel, there will be no electrification.
Trains will use battery power, where there is no electrification.
This article on Modern Railways gives more information.
This OpenRailwayMap shows the electrification around Cardiff Central and Queen Street stations.
Note.
- Electrified lines are shown in red.
- Unelectrified lines are shown in black.
- The four-platform Cardiff Queen Street station is marked by the blue arrow in the North-East corner of the map.
- There appears to be no plans for electrification in Cardiff Queen Street station.
- The electrified line across the map is the South Wales Main Line.
- The nine-platform Cardiff Central station sits on the South Wales Main Line.
- The main line platforms at Cardiff Central station are electrified, but it appears that Platforms 6.7 and 8. that will serve the South Wales Metro, will not be electrified.
- The line going to the South-East is the branch to Cardiff Bay station.
- The Southern part of this branch appears to be planned to be electrified. so that it can charge the tram-trains before they return North.
This article on Modern Railways says this about catenary-free sections (CFS) in the electrification of the South Wales Metro.
Catenary-free sections are concentrated on areas where it is disproportionately expensive to erect overhead wires. These include the area around Cardiff Queen Street station and the adjacent junction, which has complicated switches and crossings. North of Queen Street, the Cathays area adjacent to Cardiff University and the hospital would present a significant electromagnetic compatibility challenge, so a CFS avoids this complication. Other catenary-free areas will include Pontypridd, where the station features listed canopies and the track is curved, and around the new depot at Taff’s Well, where there will be a significant number of new switches and crossings as well as challenges around highway bridges.
I am in touch with two major electrification companies and I am sure we’ll be seeing a lot more crafty electrification and the use of battery-electric trains.
High Speed Two To Holyhead
Rishi Sunak has just announced that the North Wales Main Line will be electrified, along with the cancellation of further phases of High Speed Two.
I have written about this topic before in Could High Speed Two Serve Holyhead?.
In that post, I started with this question and answer.
Why?
It could be a way to create a zero- or low-carbon route between the islands of Great Britain and Ireland.
In Could High Speed Two Finish At Lichfield?, I discussed, what might happen if the Birmingham to Manchester leg of High Speed Two were to be scrapped.
This was my main conclusion.
I strongly believe that an upgraded Trent Valley Line linked to a shortened High Speed Two at Lichfield could improve journey times between London, Birmingham and the North.
As the current Holyhead services will pass this junction between the Trent Valley Line and High Speed Two, there is no reason, why they couldn’t take High Speed Two to and from London, if the service was run by High Speed Two Classic-Compatible Trains.
These are further thoughts.
Timings
These would be the times in hours:minutes.
- Bangor – 2:42
- Chester – 1:28
- Holyhead – 3:10
- Llandudno Junction – 2:24
Currently, Holyhead is three hours and forty-five minutes.
Would the Electrification Be Full Or Partial Between Crewe And Holyhead?
This question will be increasingly asked about electrification.
Consider.
- CAF, Hitachi, Siemens and Stadler are all developing battery-electric technology for trains.
- The UK’s first battery-electric train service goes into service tomorrow between Liverpool and Headbolt Lane station.
- Freight locomotives are increasingly being ordered with both electric and diesel power.
- Some of the castles, countryside and other monuments wouldn’t be enhanced, with lots of overhead electrification.
I think it is likely, that electrification will increasingly have gaps for visual, technical or heritage reasons.
Electrification of the North Wales Coast Line with other small improvements could probably reduce the journey time between London and Holyhead to around three hours.
Would There Be Enough Paths On The Trent Valley Line And High Speed Two?
This graphic shows High Speed Two services after Phase 2b is completed.
Note.
- Services shown in blue are run by High Speed Two Full Size trains.
- Services shown in yellow are run by High Speed Two Classic-Compatible trains.
- There are a total of 23 train paths of which eleven would need to go along the Trent Valley Line.
- The three London-Manchester services and the two Birmingham-Manchester services would have to be run by High Speed Two Classic-Compatible trains.
- The second Liverpool train is only a single train, but it could be a pair, that split at Crewe, with one train going to Liverpool and the other to Chester and North Wales.
- All the Avanti West Coast services, currently using the Trent Valley Line would probably be replaced by High Speed Two services.
There would have to be a bit of reorganising, but I suspect an hourly path could be found for a train between London and Holyhead.
A Fast Green Route To The Emerald Isle
Electrification of the North Wales Coast Line with other small improvements could probably reduce the journey time between London and Holyhead to around three hours.
This service could be paired with a fast zero-carbon ferry to the island of Ireland?
Conclusion
I am fairly sure that an HS2 service to Holyhead could be run, once the North Wales Coast Line is electrified.

Cunning Electrification On The North London Line
I took a trip on the North London Line from Highbury & Islington station to Richmond station.
I took various pictures on the way.
25 KVAC Overhead Electrification
East of Acton Central station, typical 25 KVAC overhead electrification is used.
It may need to be beefed up, if more large electric locomotives haul freight trains along the North London Line.
Gunnersbury Station
Gunnersbury station is a two-platform station with London Underground four-rail electrification.
It can be used by London Underground S-Stock and London Overground Class 378 trains.
It must help that both trains were built by Bombardier in Derby.
Kew Gardens Station
Kew Gardens station is a two-platform station with London Underground four-rail electrification.
As with Gunnersbury station, both types of train can use both platforms.
Richmond Station
Richmond station is both a through and terminal station.
Note.
- Platforms 1 and 2 are through platforms for South Western main line services.
- Platforms 3 to 7 are for terminating London Underground and Overground services.
- Platforms 1 to 3 have traditional third-rail electrification.
- Platforms 4 to 7 have London Underground four-rail electrification.
- If needed, it may be possible to add another platform between platforms 3 and 4.
It looks like a lot of flexibility has been built in.
I have a few general thoughts.
Getting The Voltages Right
London Underground’s system used to use 630 VDC for its four-rail system, whereas Network Rail’s system uses 750 VDC.
I wouldn’t be surprised to find out that both trains use quality power electronics that can work on a range of voltages. This would enable London Underground to up their voltage to the same 750 VDC as used by Network Rail.
In Chiltern Sets Out New Fleet Ambitions, I talked about how Chiltern Railways could use London Underground’s four-rail electrification between Harrow-on-the-Hill and Amersham stations to charge the batteries.
As an electrical engineer, I don’t think this is outrageous.
Liverpool Lime Street And Newcastle By Battery-Electric Class 802 Train
After my visit to Morley station, which I wrote about in Morley Station – 17th August 2023, in this post, I look at how a battery-electric Class 802 train might run between Liverpool Lime Street And Newcastle stations.
These are the various sections of the route.
- Liverpool Lime Street and Manchester Victoria – 31.6 miles – 36 minutes – Electrified
- Manchester Victoria and Huddersfield – 25.7 miles – 30 minutes – Not Electrified
- Huddersfield and Dewsbury – 8 miles – 7 minutes – Currently Being Electrified
- Dewsbury and Leeds – 9.1 miles – 14 minutes – Not Electrified
- Leeds and York – 25.8 miles – 30 minutes – Currently Being Electrified
- York and Newcastle – 80.2 miles – 58 minutes – Electrified
Note.
- Liverpool Lime Street and Manchester Victoria, Leeds and York and York and Newcastle are all long enough to fully charge a battery-electric train.
- There is electrification of both ends of the route.
- Manchester Victoria and York is a distance of 68.6 miles.
- The total route length is a distance of 180.4 miles.
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 a paragraph.
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.
Could the trial be conducted on TransPennine Express’s Liverpool Lime Street And Newcastle route?
- The total route length is a distance of 180.4 miles.
- The two electrified sections at the ends of the route; Liverpool Lime Street and Manchester Victoria and York and Newcastle are both long enough to fully charge a battery-electric train.
- The central section between Manchester Victoria and York is not overly long at 68.6 miles.
- The route is convenient for Hitachi’s headquarters at Newton Aycliffe.
It looks like, the Liverpool Lime Street And Newcastle route would make an ideal test route for battery-electric Class 802 trains.
Manchester Piccadilly And Newcastle By Battery-Electric Class 802 Train
This is a very similar route to the Liverpool Lime Street And Newcastle route with a different Western terminal.
These are the various sections of the route.
- Manchester Piccadilly and Huddersfield – 25.5 miles – 42 minutes – Not Electrified
- Huddersfield and Dewsbury – 8 miles – 10 minutes – Currently Being Electrified
- Dewsbury and Leeds – 9.1 miles – 14 minutes – Not Electrified
- Leeds and York – 25.8 miles – 30 minutes – Currently Being Electrified
- York and Newcastle – 80.2 miles – 58 minutes – Electrified
Note.
- Turnround time at Manchester Piccadilly and York and Newcastle are all long enough to fully charge a battery-electric train.
- There is electrification of both ends of the route.
- Manchester Piccadilly and York is a distance of 68.4 miles.
- The total route length is a distance of 148.5 miles.
Like the Liverpool Lime Street And Newcastle route, I believe the Manchester Piccadilly And Newcastle route would make an ideal test route for battery-electric Class 802 trains.
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.
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.
