Batteries Ordered For Grand Central Inter-City Trains
The title of this post, is the same as that of this article on Railway Gazette.
These three paragraphs add detail to the article.
Hitachi Rail has selected Turntide Technologies to supply lithium iron phosphate batteries for use on electric-diesel-battery hybrid inter-city trainsets it is to build for Arriva’s open access operator Grand Central.
Nine five-car trainsets are to be manufactured at Hitachi Rail’s Newton Aycliffe factory for delivery in 2028 under a order placed by leasing company Angel Trains in March.
Under the latest agreement announced on July 2 Hitachi Rail will place orders worth nearly £10m for Turntide to continue with R&D and supply next-generation LFP batteries, which are designed to be smaller and more powerful than previous lithium-ion batteries. The Safety Integrity Level 2 and IEC 61508 compliant battery management system will detect and mitigate hazards and meet the IEC 62243 cybersecurity standard.
There is also this paragraph, which describes the benefits of the trains.
The battery technology is expected to cut the Grand Central trains’ emissions and fuel consumption by around 30%, with the trains entering and exiting stations in zero-emission mode to improve air quality and reduce noise in urban centres.
Angel Trains, Grand Central, Hitachi Rail and Turntide Technologies seem to be playing this all carefully, as I suppose that they don’t want to be left with a large problem, if the current government decides to take over open access services.
Arriva Group Invests In New Battery Hybrid Train Fleet In Boost To UK Rail Industry
The title of this post, is the same as that of this news item from Arriva Group.
These four bullet points act as sub-headings.
- Order worth around £300 million for fleet of new trains, which will increase seats by 20 per cent, improving capacity and connectivity.
- 45 rail cars to be manufactured at Hitachi Rail in the North East and financed by Angel Trains, helping secure highly skilled jobs and unlocking a new advanced manufacturing opportunity for rail.
- State-of-the-art ‘tri-mode’ train technology has proven its ability to cut emissions and fuel costs by around 30 per cent to support UK Government’s decarbonisation agenda.
- Announcement is made from Hitachi’s Newton Aycliffe factory and attended by the Secretary of State for Transport, Heidi Alexander MP.
These three paragraphs give more details.
Arriva Group announced today an order for nine cutting-edge battery hybrid trains to replace its entire Grand Central fleet, providing a major boost to regional economies and offering passengers more comfortable, greener travel options.
The order for 45 Hitachi Rail ‘tri-mode’ cars, which have the flexibility to run on electrified and non-electrified tracks, along with a 10-year maintenance contract, represents an investment of around £300 million. Tri-mode means the trains can be powered using electricity, battery or diesel.
It follows approval by the rail regulator for extended track access rights for Grand Central’s existing services through to 2038, with the investment underpinning Arriva’s long-term commitment to UK rail and to delivering sustainable public transport solutions to communities up and down the country and across Europe.
The trains will be built by Hitachi at Newton Aycliffe.
I have some further thoughts and questions.
What Distances Will The Trains Run Away From Electrification?
The distances that the various services will run away from electrification are as follows.
- King’s Cross and Bradford Interchange – Doncaster and Bradford Interchange – 52.1 miles.
- King’s Cross and Cleethorpes – Doncaster and Cleethorpes – 52.1 miles.
- King’s Cross and Sunderland – Longlands junction and Sunderland – 48.5 miles.
It would appear that a train with a range away from electrification of 55 miles would be enough, if there were to be charging at all the destinations.
Will The Trains Be Able To Take The Great Northern And Great Eastern Joint Line (GNGE) Diversion Via Lincoln On The East Coast Main Line?
I discussed using this diversion in detail in London And Edinburgh By Lumo Using the Joint Line Diversion.
In that post, I said this.
The January 2024 Edition of Modern Railways says that the diversion is approximately 90 miles or 145 kilometers.
If the trains have a 90 mile capability on batteries and/or diesel, they will be able to use the diversion.
As Hull Trains, LNER and Lumo all need this ability to take the GNGE Diversion, I suspect, it will be a tick-box on the order form for the trains.
When Will The Trains Be In Service?
The news item says this.
The trains will be delivered in 2028 under a 10-year leasing arrangement, in partnership and financed by Angel Trains.
Will The New Trains Be Faster?
They might save a couple of minutes, if Doncaster is the first stop.
Will The New Trains Be Quieter?
The news item says this about noise and emissions.
State-of-the-art ‘tri-mode’ train technology has proven its ability to cut emissions and fuel costs by around 30 per cent to support UK Government’s decarbonisation agenda.
Hitachi have said that the diesel engines will not run in stations.
Could The Trains Run Grand Central’s Routes Carbon-Free?
In The Data Sheet For Hitachi Battery Electric Trains, I came to these conclusions
- The battery pack has a capacity of 750 kWh.
- A five-car train needs three battery-packs to travel 100 miles.
- A nine-car train needs five battery-packs to travel 100 miles.
- The maximum range of a five-car train with three batteries is 117 miles.
- The maximum range of a nine-car train with five batteries is 121 miles.
As battery technology gets better, these distances will increase.
If I was choosing the trains for Grand Central, the trains would be able to operate these routes without using diesel.
- Doncaster and Bradford Interchange and return.
- Doncaster and Cleethorpes and return.
- Longlands junction and Sunderland and return.
Passengers might not like to have noisy passengers.
Probably, the best insurance policy to avoid running out of battery power, would be to have perhaps fifty metres of electrification at terminal stations. Hitachi claim they can offer a nice line in short lengths of electrification.
Quiet Trains Should Attract Passengers
I’ve seen it before and also with buses.
The Number Of Trains Ordered
The basic order is for nine trains, but Railway Gazette says this.
Arriva welcomed the ‘swift decision-making’ by ORR and the backing of the Department for Transport and Network Rail. It has also submitted applications to run more trains to Bradford and introduce services to Cleethorpes, and has an option to buy more trains if these are approved.
I’ve read somewhere that the option is for three extra trains.
So that’s a total of twelve, which would replace the ten Class 180 trains and two Class 221 trains, that Grand Central Trains currently run.
What About Chiltern Railways And CrossCountry?
Train operating companies Chiltern Railways, CrossCountry and Grand Central Trains are all wholly owned subsidiaries of Arriva Trains UK, who are described like this in the first paragraph of their Wikipedia entry.
Arriva UK Trains Limited is the company that oversees Arriva’s train operating companies in the United Kingdom. It gained its first franchises in February 2000. These were later lost, though several others were gained. In January 2010, with the take-over of Arriva by Deutsche Bahn, Arriva UK Trains also took over the running of those formerly overseen by DB Regio UK Limited
Arriva is ultimately owned by American infrastructure investment company; I Squared Capital.
Both Chiltern Railways and CrossCountry have trains, that are coming to the date, when they will need to be replaced and similar trains to those ordered by Grand Central could be suitable. to replace some.
Chiltern Railways have six rakes of Mark 3 coaches, that are hauled by diesel locomotives between London Marylebone and Birmingham Moor Street stations, These rakes of coaches could be replaced by Hitachi tri-mode trains, of perhaps five or six cars.
Chiltern Railways also have about sixty assorted diesel multiple units totalling up to about 150 carriages.
CrossCountry Trains have twenty-nine two- or three-car Class 170 trains and sixty-one four- or five car Class 220 or 221 trains. All these ninety trains were built this century and are diesel-powered.
The Government’s policy of net-zero by 2050, would probably mean a significant number of these smaller diesel multiple units need to be replaced by 2030.
If the Grand Central Trains new Hitachi trains are a success, then changing the longer four-, five- and six-car trains for similar Hitachi trains, would be a low-risk replacement strategy for I Squared Capital, that could be applied at Chiltern Railways and CrossCountry.
I can also see a need for a two-, three- or four-car tri-mode train for Chiltern Railways and CrossCountry.
Was The Date Of The Announcement Significant?
In October 2020, I wrote Hitachi Targets Export Opportunities From Newton Aycliffe and I believe that tri-mode trains like these that Grand Central have ordered could have export opportunities.
One country for exports has possibilities and that is the United States.
- Hitachi AT-300 trains like these don’t need expensive high-speed tracks and there are probably many lines in the United States, where these trains could fit existing tracks.
- This page on the Hitachi Rail web site is entitled Hitachi Rail in the USA and Canada.
- In the UK, companies like GWR, LNER, Southeastern and TransPennine Express effectively use theHitachi trains as fast commuter trains on some routes.
- Trump’s tariffs would only be 10 % on these trains.
- The Grand Central version looks very stylish!
- Hitachi’s battery technology is owned by Turntide Technology, who are a US company.
- For some routes, the trains would probably only need to be battery-electric.
Has the experience of running Chiltern Railways, CrossCountry and Grand Central Trains convinced I Squared Capital, that running railways is a good investment?
Have I Squared Capital identified some railroads in the United States, that could follow a similar upgrade path to Chiltern Railways?
Was it significant that the order was announced the day after Trump’s tariffs?

Brand New Battery Technology To Be Trialled On TransPennine Train
The title of this post, is the same as that of this press release from Hitachi.
These three bullet points, act as sub-headings.
- First-ever trial in the UK to replace a diesel engine with a battery on an intercity train is underway.
- Pioneering collaboration between Angel Trains, TransPennine Express, Turntide Technologies and Hitachi Rail.
- Hitachi Rail has built a battery using the North East supply chain, with one battery unit predicted to reduce emissions and fuel costs by as much as 30%.
These are my thoughts on some of the paragraphs in the press release.
The First Paragraph
This is the first paragraph.
Testing of the UK’s first intercity battery train commenced earlier today. The battery, which generates a peak power of more than 700kw, has now been successfully retrofitted onto a TransPennine Express ‘Nova 1’ train (five-carriage intercity Class 802), ahead of the trial on Transpennine routes this summer.
Each of the three diesel power packs in on of TransPennine Express’s Class 802 trains can generate 700 kW, so the battery packs can provide the same power as the current Rolls-Royce mtu diesel power packs.
The Third Paragraph
This is the third paragraph.
The single battery unit is incredibly powerful, storing enough electricity to power more than 75 houses for a day. This impressive energy and power density will deliver the same levels of high-speed acceleration and performance, while being no heavier than the diesel engine it replaces.
This equity of high-speed acceleration and performance is to be expected, as the train power and weight is the same, if the power is diesel engines or batteries.
The Fourth Paragraph
This is the fourth paragraph.
The installation of a battery will reduce emissions and improve energy efficiency. It is predicted to reduce emissions and fuel costs by as much as 30% on a Hitachi intercity train.
I would assume that this improvement in emissions and fuel costs, is due to the use of regenerative braking to recharge the batteries, when the train slows down.
The Fifth Paragraph
This is the fifth paragraph.
Most importantly for passengers, the trial will test how intercity trains can enter, alight and leave non-electrified stations in zero-emission battery mode to improve air quality and reduce noise pollution.
As the trains enter a non-electrified station, the regenerative braking will recharge the batteries to both power the train in the station and accelerate the train on its way.
The Seventh Paragraph
This is the seventh paragraph.
The trial will provide real-world evidence to inform the business case for a 100% -battery-electric intercity train, capable of running up to 100km in battery mode. This remarkable range means this battery technology could be deployed to cover the final non-electrified sections of intercity routes in the coming years. It will also demonstrate how battery technology can reduce infrastructure costs by reducing the need for overhead wires in tunnel sections and over complex junctions.
Note that 100 kilometres is 62.1 miles.
You can never do too much real world testing!
These are my further thoughts.
Acceleration And Braking Under Battery Power
This graph from Eversholt Rail, shows the acceleration and deceleration of a five-car Class 802 electric train.
As Hitachi have said in the press release that.
- The weight of a battery pack is the same as a diesel engine.
- The power of a battery pack is the same as a diesel engine.
The acceleration and braking curve for a Class 802 train, with a single traction battery will surely be the same.
Would this mean, that if a battery-electric train replaced a diesel-electric train, the timetable would be the same?
What would be the effects, if a second diesel engine were to be replaced with a battery pack?
- The train would still weigh the same.
- The train’s performance would still be the same.
- The train would have 1400 kW of power available, but I doubt this could be used efficiently, as it might exceed the train’s performance limits.
- The train would have enough electricity for a 200 kilometre or 124.3 mile range.
There might be a need for a sophisticated control system to set the power mode, but in my experience of riding in the cab of an InterCity 125 and a Boeing 747, drivers or pilots have enough intelligence and fingers to control systems with multiple engines.
What would be the effects, if a third diesel engine were to be replaced with a battery pack?
- The train would still weigh the same.
- The train’s performance would still be the same.
- The train would have enough electricity for a 300 kilometre or 186.4 mile range.
The range is sufficient for a lot of routes.
London And Beverley
Consider.
- This route has 44.3 miles of unelectrified track between Temple Hirst Junction and Beverley.
- One battery range is 100 kilometres or 62.1 miles.
- As the trains have three slots for battery packs or diesel engines, they could always carry a diesel engine for emergencies.
The route could be run in one of two ways.
- By using one battery, that would be charged at Beverley.
- By two batteries, that would be charged on the main line to the South of Temple Hirst Junction. One battery would be used in each direction.
Note.
- The second method would not require any new infrastructure at Beverley or Hull.
- All batteries would be identical 100 km batteries.
- Trains would just swap an appropriate number of diesel engines for batteries.
The service could run as soon as the trains had the power transplants.
Using The Lincoln Diversion
In Extra Luggage Racks For Lumo, I also talked about Lumo taking the diversion via Lincoln.
Consider.
- This route is 88.5 miles of unelectrified track.
- It would be possible to be handled by a Class 802 train with two battery packs.
- Hull Trains will need battery packs to get to Beverley.
- Some LNER services will use battery packs.
Perhaps trains will use one battery to Lincoln and one from.
Crewe And Holyhead
In October 2023, the government said, that the North Wales Coast Line would be electrified.
Consider.
- Crewe and Holyhead are 105.5 miles apart.
- The route currently has no electrification.
- It has been planned to electrify the 21.1 miles between Crewe and Chester for some time.
- A lot of the route West of Chester may arouse the wrath of the Nimbies and be politically difficult to electrify, as castles and electrification don’t mix.
- Llandudno Junction station might be a station, where trains could be charged.
- Shotton and Chester stations need rebuilding.
- The line is not short of electric power, because of Electric Mountain and the windfarms along the coast.
- The route will soon be served by Hitachi Class 805 trains.
I believe the North Wales Coast Line could be one of those routes, which Hitachi’s partial electrification might be ideal.
I also believe that, it could be an extension of High Speed Two from Crewe, which provided a zero-carbon route between London and Ireland.
Conclusion
I can see if the tests perform as expected, that there will be some battery express trains running soon.
What Will Be The Range Of A Hitachi Class 800 Battery Train?
I feel now, I have enough information to make an educated, at what the distance a five-car Class 800 or Class 802 train will travel on batteries.
Previous Battery-Electric Trains
These are examples of previous distances.
- A Bombardier engineer told me eight years ago, that the battery-electric Class 379 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.
Engineering Ambition
Several times in my life, I’ve got fired up about engineering or software projects and I like to think, I’ve produced the best and fastest solution.
For this reason, I believe that Hyperdrive Innovation, who are now part of Turntide Technologies, and Hitachi will set themselves three objectives with the design of the the battery packs for the Class 800 or Class 802 train.
- The battery-electric Class 802 will outperform the Stadler FLIRT Akku in terms of speed and distance.
- The battery packs will be plug-compatible with the diesel engines, so there will only be minor software modification to the trains.
- The train will be able to be handle all Great Western Railway’s routes without using diesel.
- I wouldn’t be surprised that on many routes the train will cruise at over 110 mph on batteries.
I also suspect they want the Akku’s Guinness world record, which will mean the range will be in excess of 139 miles.
More On LNER’s Ten New Bi-Modes
I wrote about these trains in LNER Seeks 10 More Bi-Modes.
This was my conclusion.
There is a lot of scope to develop LNER’s services.
I think it is likely that the order will go to Hitachi.
But as I indicated, I do believe that there is scope for a manufacturer to design a zero-carbon train, that was able to serve Aberdeen and Inverness.
- I suspect a fleet of ten trains would be sufficient.
- Trains would use the 25 KVAC overhead electrification, where it exists and hydrogen or battery power North of the wires.
The trains would also be capable of being upgraded to higher speeds, should the East Coast Main Line be turned into a High Speed Line.
I also think, that whatever trains are bought, there will be a large upgrading of the existing Hitachi fleet, which will add batteries to a lot of trains.
In the July 2023 Edition of Modern Railways, there is an article, which is entitled LNER Embraces Pioneering Spirit, which takes the form of an interview with LNER’s Managing Director; David Horne.
In a section, which is entitled ‘225’ Replacement, this is said.
Meanwhile, Mr Horne is looking to what might replace the InterCity 225 fleet, now smartly repainted in a scheme which pays homage to the original ‘Swallow’ livery. While there were fears this fleet may be withdrawn as an economy measure, the ‘225s’ are now on lease until at least next summer.
But Mr Horne says obsolescence issues are a real challenge and LNER will struggle to maintain the fleet beyond 2025, and from the May 2023 timetable change the number of daily diagrams was reduced from five to four to conserve the fleet’s mileage. Much of the heavy maintenance work had previously been carried out at Wabtec’s Doncaster site, but this facility is no longer available, and while a recent reliability improvement programme is bearing fruit, the challenges remain. The crunch point comes with the transition to ETCS at the southern end of the ECML as part of the East Coast Digital Programme – Mr Horne says LNER does not want to fit cab signalling on the ‘225s’.
The solution to this issue is to procure additional trains to run alongside the 65 Azumas, and LNER went out to tender in October 2020 for a fleet of 10 trains with self-power capability.
While a preferred bidder has been identified, the business case to proceed with the procurement is awaiting approval, but Mr Horne is still hopeful this project can be progressed.
The current plan envisages the new trains broadly replacing the ‘225s’ on Leeds and York diagrams, but a major benefit with the new fleet would be during engineering work – at present LNER has to withdraw services to places such as Harrogate and Hull to concentrate its bi-mode Azumas on services using non-electrified diversionary routes, and having more stock with self-power capability would ease the issue.
Currently, LNER has these Azumas and InterCity 225s in its fleet.
- Five-car bi-mode Class 800 trains – 10
- Nine-car bi-mode Class 800 trains – 13
- Five-car electric Class 801 trains – 12
- Nine-car electric Class 801 trains – 30
- Nine-car electric ImterCity 225 trains – 8
Note.
- There are 23 bi-mode trains and 50 electric trains.
- There are 167 bi-mode carriages and 302 electric carriages.
- Currently 31.5 % of the trains are bi-mode.
- With ten new bi-mode trains and no InterCity 225 trains, 44 % of the fleet will be bi-mode.
Is this increase in the percentage of the fleet, that are bi-mode acceptable?
LNER’s Two Needs
Let’s look at LNER’s needs, which are actually two separate sub-needs.
- There is a need for ten new trains to replace the InterCity 225 trains.
- There is a need to increase the size of the bi-mode fleet to be able to use the Great Northern and Great Eastern Joint Line and other non-electrified routes to by-pass engineering works.
Note.
- I suspect that as Mr Horne explained, there are only five or possibly four InterCity 225s diagrammed on a particular day, then perhaps ten five-car bi-mode Class 800 trains, might be able to cover for the retirement of the InterCity 225s.
- These trains would work as pairs to Leeds and York to replace the InterCity 225 capacity.
- If required they could split and join at Leeds and York to serve other destinations.
- The diversion route of the Great Eastern Joint Line has an unelectrified distance of 93.7 miles and the route is electrified at both ends.
- Would a battery-electric Class 800 train handle this distance? I suspect if Stadler can do it, then Hitachi and Turntide Technology will be able to do it too!
LNER will have replaced the InterCity 225s and acquired ten new five-car blockade runners.
As an order for ten new five-car battery-electric trains, is not to be sneezed at, I suspect Hitachi will make sure that their new battery-electric variants have enough range.
So this would mean that the range of a five car battery-electric Class 800 train, should be in excess of 93.7 miles.
Advantages Of Converting Class 800 and Class 802 Trains To Battery-Electric Operation
It should be noted that the five-car and nine-car Class 800 and Class 802 trains have specific advantages when it comes to converting them to battery-electric operation.
- They are modern trains, that are still in production, so every bit of information about the train is known down to the last nut, bolt and plastic clip.
- Like most modern trains, hey have a sophisticated computer system controlling the train.
- They have spaces for three, four or maybe even five diesel engines under the floor, which could be used for a battery-pack in every car designed to hold a diesel engine.
- The train has an electric bus between nose and tail.
- As is shown, when the trains change between diesel and electric, the pantograph can go up and down with all the alacrity of a whore’s drawers.
- The trains can be converted between bi-mode and electric, by adding or removing diesel packs. I doubt this feature will be removed, as batteries replace diesels.
With my Electrical and Control Engineer’s hard hat on, I doubt there is anything to stop a Class 800 or Class 802 train being fitted with three or more batteries to create a 125 mph train, with a range approaching two hundred miles on battery power.
The initial name of these Hitachi trains was the Hitachi Super Express. Is this train the Hitachi Super Battery Express?
But it would appear, that for their initial needs, LNER, just need a range to handle the near hundred miles of the Great Northern and Great Eastern Joint Line.
Inverness and Aberdeen will come later.
Conclusion
The first version of the battery-electric train will have a range of around a hundred miles, so that they can handle the Great Northern and Great Eastern Joint Line diversion, which is 93.7 miles on battery power.
But fairly soon after introduction into service, I will be very surprised if they don’t claim the Guinness world record by running farther than the Stadler FLIRT Akku’s 139 miles.
No-one likes being second!
Thoughts About Electrification Through Devon And Cornwall
Distances
I’ll start by looking at a few distances.
- Penzance and Taunton – 162.3 miles
- Penzance and Exeter St. David’s – 131.5 miles
- Penzance and Plymouth – 79.5 miles
- Taunton and Exeter St. David’s – 30.7 miles
- Plymouth and Exeter St. David’s – 52 miles
- Taunton and Newbury – 89.6 miles
- Plymouth and Taunton – 82.8 miles
- Taunton and Paignton – 59 miles
- Taunton and Patchway – 51.7 miles
Note.
- Patchway and Newbury are already electrified to Cardiff Central and London Paddington respectively.
- Bombardier’s engineer told me eight years ago, that the battery-electric Class 379 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 135km On Battery.
The rail distances in Devon and Cornwall are getting closer to being within the capability of trains fitted with batteries.
Station Stop Times
These are typical times that trains stop in the more important stations between Taunton and Penzance.
- Taunton – < 2 mins
- Tiverton Parkway – < 2 mins
- Exeter St. Davids – 2 mins
- Newton Abbot – < 2 mins
- Totnes – < 2 mins
- Plymouth – 11 minutes
- Devonport – < 2 mins
- Saltash – < 2 mins
- Menheniot – < 2 mins
- Liskeard – < 3 mins
- Bodmin Parkway – 2 mins
- Lostwithiel – 2 mins
- Par – 2 mins
- St. Austell – 2 mins.
- Truro – 2 mins
- Redruth – 2 mins
- Camborne – 2 mins
Note.
- The timings were for today.
- The Cardiff and Penzance services were being run by five-car Class 802 trains.
- Most station stops are around two minutes or less, but Plymouth on this train was eleven minutes.
I find it interesting that the Plymouth stop takes so much longer.
Train Stops At Plymouth
I looked at about twenty trains stopping at Plymouth, that included these services.
- London Paddington and Penzance
- Penzance and London Paddington
- Cardiff Central and Penzance
- Penzance and Cardiff Central
Note.
- I found an average time of eight minutes.
- Eleven minutes was a common stop.
- Eight minutes could be enough time for the rail equivalent of a Formula One splash and dash.
- CrossCountry services were going through the station in three minutes.
I am led to believe that the timetable used by the GWR trains would allow a quick battery charge at Plymouth station.
This OpenRailwayMap shows the platforms at Plymouth station.
Note.
- London is to the East and Penzance is to the West.
- Platform numbers increase from South to North.
- The two East-facing bay platforms are Platforms 1 and 2.
- The West-facing bay platform in the South-West corner is Platform 3.
- Platform 4 shares the island with the bay platforms 1, 2 and 3.
- Most trains going to Penzance use Platform 4.
- Platforms 5 and 6 share the centre island platform.
- Platforms 7 and 8 share the Northernmost island platform.
- Most trains going towards London use Platform 7.
- Wikipedia indicates that the track layout is comprehensive and allows a lot of operational flexibility.
Although the station was completed around forty years ago, it could have been designed for handling modern battery-electric trains.
- There are three bay platforms numbered 1 to 3, to charge local services and send them on their way.
- Trains can arrive and depart in the five through platforms, numbered 4 to 8, from either direction.
- Two days ago, a nine-car London Paddington to Plymouth train terminated in Platform 7. After waiting an hour it returned to London. An hour would be enough time to fully-charge a train.
- As many platforms as needed could be electrified.
I am fairly sure, that most battery-electric trains could be timetabled to leave Plymouth station with full batteries.
Turnround At Penzance
I have found these turnrounds.
- 802113 arrived from Paddington at 1142 and left for London at 1215
- 802022 arrived from Paddington at 1307 and left for London at 1415
- 802103 arrived from Paddington at 1500 and left for London at 1615
This OpenRailwayMap shows the platforms at Penzance station.
Note.
- The three example trains used Platform 1.
- Platform 1 is the long platform on the landward side of the station.
- Platforms are numbered 1 to 4 from left to right.
- An appropriate number of platforms would be electrified to charge trains terminating at Penzance.
Trains would appear to have plenty enough time to recharge, so they would start their return journey with full batteries.
Engineering Ambition
Several times in my life, I’ve got fired up about engineering or software projects and I like to think, I’ve produced the best and fastest solution.
For this reason, I believe that Hyperdrive Innovation, who are now part of Turntide Technologies, and Hitachi will set themselves three objectives with the design of the the battery packs for the Class 802 train.
- The battery-electric Class 802 will outperform the Stadler FLIRT Akku in terms of speed and distance.
- The battery packs will be plug-compatible with the diesel engines, so there will only be minor software modification to the trains.
- The train will be able to be handle all Great Western Railway’s routes without using diesel.
- I wouldn’t be surprised that on many routes the train will cruise at over 110 mph on batteries.
I also suspect they want the Akku’s Guinness world record, which will mean the range will be in excess of 139 miles.
Battery Range Needed For Routes
These are routes that need to be covered by battery-electric Class 802 trains or similar.
- Avanti West Coast – Crewe and Chester – 22.2 miles
- Avanti West Coast – Crewe and Holyhead – 105.5 miles
- Avanti West Coast – Crewe and Llandudno Junction – 65.5 miles
- Avanti West Coast – Crewe and Wrexham – 34.4 miles
- Avanti West Coast – Shrewsbury and Wolverhampton – 29.7 miles
- Great Western Railway – Penzance and Plymouth – 79.5 miles
- Great Western Railway – Plymouth and Taunton – 82.8 miles
- Great Western Railway – Taunton and Patchway – 51.7 miles
- Great Western Railway – Newbury and Taunton – 89.6 miles
- Great Western Railway – Taunton and Paignton – 59.0 miles
- Great Western Railway – Weston-super-Mare and Chippenham – 43.5 miles
- Great Western Railway – Oxford and Great Malvern – 65.6 miles
- Great Western Railway – Oxford and Hereford – 86.3 miles
- Great Western Railway – Oxford and Worcester Foregate Street – 57.6 miles
- Great Western Railway – Oxford and Worcester Shrub Hill – 57.2 miles
- Great Western Railway – Cheltenham Spa and Swindon – 43.2 miles
- Great Western Railway – Cardiff Central and Carmarthen – 77.4 miles
- Great Western Railway – Cardiff Central and Pembroke Dock – 118.9 miles
- Great Western Railway – Cardiff Central and Swansea – 45.7 miles
- Hull Trains – Beverley and Temple Hirst Junction – 44.3 miles
- Hull Trains – Hull and Temple Hirst Junction – 36.1 miles
- LNER – Hull and Temple Hirst Junction – 36.1 miles
- LNER – Middlesbrough and Longlands Junction – 22.2 miles
- LNER – Sunderland and Longlands Junction – 48.5 miles
- LNER – Lincoln Central and Newark Northgate – 16.6 miles
- LNER – Leeds and Bradford – 13 miles
- LNER – Leeds and Harrogate – 18 miles
- LNER – Leeds and Huddersfield – 17 miles
- LNER – Stirling and Inverness – 146 miles
- LNER – Edinburgh Haymarket and Aberdeen – 130 miles
- LNER – Peterborough and Doncaster via Great Northern and Great Eastern Joint Line – 93.7 miles
- South Western Railway – Basingstoke and Exeter St. David’s – 124.5 miles
- TransPennine – Hull and Micklefield – 42 miles
- TransPennine – Longlands Junction and Saltburn – 34.7 miles
- TransPennine – York and Scarborough – 42 miles
- TransPennine – Doncaster and Cleethorpes – 52.1 miles
- TransPennine – Stockport and Doncaster – 55.4 miles
- TransPennine – Stockport and Cleethorpes – 107.5 miles
Note.
- Stirling and Inverness and Edinburgh Haymarket and Aberdeen could be shortened by up to thirty miles, by planned electrification in Scotland.
- I have assumed that the TransPennine Upgrade has been completed.
- It looks like a battery-electric Class 802 train could use the Great Northern and Great Eastern Joint Line diversion via Lincoln.
- I am slightly surprised, that the longest stretch of line without electrification and with a passenger service is Basingstoke and Exeter St. David’s.
Charging will be needed at some places to charge the battery-electric trains. Stations fitted with chargers could include Aberdeen, Carmarthen, Cleethorpes, Exeter St. David’s, Hereford, Holyhead, Hull, Inverness, Paignton, Penzance, Pembroke Dock, Plymouth, Swansea, Taunton, Weston-super-Mare, Worcester.
Most chargers would be a length of electrification in the platform, where the battery-electric trains terminated or passed through.
More On LNER’s Ten New Bi-Modes
I wrote about these trains in LNER Seeks 10 More Bi-Modes.
This was my conclusion.
There is a lot of scope to develop LNER’s services.
I think it is likely that the order will go to Hitachi.
But as I indicated, I do believe that there is scope for a manufacturer to design a zero-carbon train, that was able to serve Aberdeen and Inverness.
-
- I suspect a fleet of ten trains would be sufficient.
- Trains would use the 25 KVAC overhead electrification, where it exists and hydrogen or battery power North of the wires.
The trains would also be capable of being upgraded to higher speeds, should the East Coast Main Line be turned into a High Speed Line.
I also think, that whatever trains are bought, there will be a large upgrading of the existing Hitachi fleet, which will add batteries to a lot of trains.
In the July 2023 Edition of Modern Railways, there is an article, which is entitled LNER Embraces Pioneering Spirit, which takes the form of an interview with LNER’s Managing Director; David Horne.
In a section, which is entitled ‘225’ Replacement, this is said.
Meanwhile, Mr Horne is looking to what might replace the InterCity 225 fleet, now smartly repainted in a scheme which pays homage to the original ‘Swallow’ livery. While there were fears this fleet may be withdrawn as an economy measure, the ‘225s’ are now on lease until at least next summer.
But Mr Horne says obsolescence issues are a real challenge and LNER will struggle to maintain the fleet beyond 2025, and from the May 2023 timetable change the number of daily diagrams was reduced from five to four to conserve the fleet’s mileage. Much of the heavy maintenance work had previously been carried out at Wabtec’s Doncaster site, but this facility is no longer available, and while a recent reliability improvement programme is bearing fruit, the challenges remain. The crunch point comes with the transition to ETCS at the southern end of the ECML as part of the East Coast Digital Programme – Mr Horne says LNER does not want to fit cab signalling on the ‘225s’.
The solution to this issue is to procure additional trains to run alongside the 65 Azumas, and LNER went out to tender in October 2020 for a fleet of 10 trains with self-power capability.
While a preferred bidder has been identified, the business case to proceed with the procurement is awaiting approval, but Mr Horne is still hopeful this project can be progressed.
The current plan envisages the new trains broadly replacing the ‘225s’ on Leeds and York diagrams, but a major benefit with the new fleet would be during engineering work – at present LNER has to withdraw services to places such as Harrogate and Hull to concentrate its bi-mode Azumas on services using non-electrified diversionary routes, and having more stock with self-power capability would ease the issue.
Currently, LNER has these Azumas and InterCity 225s in its fleet.
- Five-car bi-mode Class 800 trains – 10
- Nine-car bi-mode Class 800 trains – 13
- Five-car electric Class 801 trains – 12
- Nine-car electric Class 801 trains – 30
- Nine-car electric ImterCity 225 trains – 8
Note.
- There are 23 bi-mode trains and 50 electric trains.
- There are 167 bi-mode carriages and 302 electric carriages.
- Currently 31.5 % of the trains are bi-mode.
- With ten new bi-mode trains and no InterCity 225 trains, 44 % of the fleet will be bi-mode.
Is this increase in the percentage of the fleet, that are bi-mode acceptable?
I wonder, if there is a more affordable and flexible way to increase the fleet size.
In the Wikipedia entry for the Class 800 train, there is a section, which is entitled Traction And Generator Units, where this is said.
The Class 800 and Class 802 bi-mode are equipped with 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. In comparison, the electric-orientated Class 801 features a single GU for a five to nine-car set, which provides emergency power for limited traction and auxiliaries if the power supply from the overhead line fails. By adding or removing GUs, a Class 800 can be converted into a Class 801 and vice versa.
Let’s look at LNER’s needs, which are actually two separate sub-needs.
- There is a need for ten new trains to replace the InterCity 225 trains.
- There is a need to increase the size of the bi-mode fleet to be able to use the Great Northern and Great Eastern Joint Line and other non-electrified routes to by-pass engineering works.
Note.
- I suspect that as Mr Horne explained, there are only five or possibly four InterCity 225s diagrammed on a particular day, then perhaps ten five-car bi-mode Class 800 trains, might be able to cover for the retirement of the InterCity 225s.
- These trains would work as pairs to Leeds and York to replace the InterCity 225 capacity.
- If required they could split and join at Leeds and York to serve other destinations.
- The diversion route of the Great Eastern Joint Line has an unelectrified distance of 93.7 miles and the route is electrified at both ends.
- Would a battery-electric Class 800 train handle this distance? I suspect if Stadler can do it, then Hitachi and Turntide Technology will be able to do it too!
LNER will have replaced the InterCity 225s and acquired ten new five-car blockade runners.
As an order for ten new five-car battery-electric trains, is not to be sneezed at, I suspect Hitachi will make sure that their new battery-electric variants have enough range.
So this would mean that the range of a five cat battery-electric Class 800 train, should be in excess of 93.7 miles.
It should be noted that the five-car Class 800 and Class 802 trains have specific advantages when it comes to converting them to battery-electric trains.
- They are modern trains, that are still in production, every bit of information about the train is known down to the last nut, bolt and plastic clip.
- Like most modern trains, hey have a sophisticated computer system controlling the train.
- They have spaces for three, four or maybe even five diesel engines under the floor, which could be used for a battery-pack in every car designed to hold a diesel engine.
- The train has an electric bus between nose and tail.
- As is shown, when the trains change between diesel and electric, the pantograph can go up and down with all the alacrity of a whore’s drawers.
- The trains can be converted between bi-mode and electric, by adding or removing diesel packs. I doubt this feature will be removed, as batteries replace diesels.
With my Electrical and Control Engineer’s hard hat on, I doubt there is anything to stop a Class 800 or Class 802 train being fitted with three or more batteries to create a 125 mph train, with a range approaching two hundred miles on battery power.
The initial name of these Hitachi trains was the Hitachi Super Express. Is this train the Hitachi Super Battery Express?
But it would appear, that for their initial needs, LNER, just need a range to handle the near hundred miles of the Great Northern and Great Eastern Joint Line.
Inverness and Aberdeen will come later.
Hull Trains
This page on the Lumo web site is entitled Greener Travel Between Edinburgh And London.
These are the first three paragraphs.
A new, 100% electric rail service is to start running between London and Edinburgh with fares for as little as £14.90 in a bid to encourage greener and more affordable travel between the capitals.
Called Lumo, it will provide low-carbon, affordable long-distance travel for over 1 million passengers per year. Over 74,500 passengers currently fly between Edinburgh and London each month3.
And with single tickets between the capitals starting from just £14.90, Lumo will be a comfortable, convenient alternative to flying that is affordable for all. Some 60% of all single fares will be available at a cost of £30 or less.
I’m sure Hull Trains, who are owned by First Group like Lumo would like to position themselves in the 100 % electric low-carbon box too!
Currently, Hull Trains’s five-car Class 802 trains, run 88.6 and 72.2 miles using diesel on round-trips to Beverley and Hull respectively from London.
If batteries were fitted to their trains to give a battery range of around a hundred miles, Hull Trains could call themselves 100 % electric.
No new infrastructure would be required, but a short length of overhead electrification in a convenient platform at Hull station would ensure the train left for London and Beverley with a full battery.
The pictures show Hull Trains’s Class 802 train in Platform 7 at Hull station.
Penzance And Taunton
This to me is the key section as if you can run a battery-electric train between these two stations it allows so many of the services to be run using zero-carbon traction.
These are distances from Taunton.
- Exeter St. David’s – 30.7 miles
- Newbury – 89.6 miles
- Okehampton – 55.3 miles
- Paignton – 59.0 miles
- Patchway – 51.7 miles
- Plymouth – 82.8 miles
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.
- All would be possible with a battery-electric train, with a hundred-mile range, leaving Taunton with a full battery.
- Charging could be needed at Okehampton and Paignton.
What is needed is some form of charging in the Taunton area.
This OpenRailwayMap shows Taunton station.
Note.
- The station has four through platforms.
- All Great Western Railway services to and from Devon and Cornwall stop in the station.
- I feel it would be possible to electrify the station, so that all stopping trains could charge the batteries.
But the problem would be, that as typically trains only stop for a couple of minutes at Taunton, there may not be enough time to take enough charge on board.
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 Collumpton.
This Google Map shows a section of the M5 North of Collumpton.
And this Google Map shows Tiverton Parkway station.
Note how the railway runs alongside the M5 to the West.
I feel that if the two new stations of Wellington and Collumpton are built between Taunton and Exeter St. David’s, then why not partially electrify the route, so that all trains would leave or pass through Taunton and Collumpton stations with full batteries.
- Going West the trains would reach Exeter St. David’s, Okehampton or Plymouth.
- Going East trains would reach Newbury for Reading and Paddington, and Patchway for Cardiff.
I believe that a battery-electric solution is possible, that would enable the decarbonisation of the Great Western Main Line all the way to Penzance.
More Trains To Carmarthen
The last time, I looked at the number of GWR trains to Carmarthen its Wikipedia entry, it was just a couple.
Today, one train per hour (tph) is shown between London Paddington and Swansea, with this supplementary information.
- 7 trains per day continue to Carmarthen, calling at Gowerton (limited), Llanelli, Pembrey & Burry Port, Kidwelly (limited) and Ferryside (limited)
- On Summer Saturdays, 2 trains per day run to Pembroke Dock, calling at all stations between Carmarthen and Pembroke Dock
In Regulator Approves New Grand Union Train Service From Carmarthen To London Paddington, I talked about the plans of Grand Union Trains to run five trains per day (tpd) between London Paddington and Carmarthen.
This would appear to give a total of twelve tpd between London Paddington and Carmarthen.
This page on the Crown Estate web site is entitled Celtic Sea Floating Offshore Wind, where this is said.
The Government has set an ambition to deliver up to 5GW of floating wind by 2030, with rapid expansion anticipated thereafter.
At The Crown Estate, we are committed to helping the UK achieve its net zero ambitions. To support this, we are excited to deliver a new leasing opportunity in the Celtic Sea for the first generation of commercial-scale floating offshore windfarms – unlocking up to 4GW of new clean energy capacity by 2035, kick-starting industry in the region, and providing power to almost four million homes.
We will be inviting full commercial scale projects up to 1GW, which may be developed in a phased or ‘stepping stone’ approach. Recognising the need to develop the UK supply chain and supporting infrastructure for this nascent technology, this approach is deliberately intended to provide opportunities for growth and investment. This will also facilitate the co-ordination of the necessary infrastructure, such as ports and grid connections, all of which are key to the sustainable development of the UK floating wind sector over the long term.
This leasing opportunity will provide the foundation for greater capacity in the future and help establish an exciting new industrial sector for the UK, creating opportunities for significant new investment in jobs, skills and infrastructure for the communities onshore.
It appears to me, that Great Western Railway and Grand Union Trains both believe that there will be large increase in demand for rail travel between London Paddington and Carmarthen and also along the South Wales Coast.
Grand Union Trains are also proposing the building of a new parkway station at Parc Felindre North of Swansea.
But then this area of South Wales and the Celtic Sea, has the four things needed for the development of up to 5 GW of offshore wind; a lot of wind, a large area of empty sea, steel and deep water ports to assemble all the floating wind turbines.
A Zero-Carbon High Speed Railway Between London Paddington And Carmarthen
Consider.
- The Great Western Railway between London Paddington and Carmarthen is 222.5 miles and trains take around three hours and fifty minutes, which is an average speed of 58 mph.
- Between Bristol Parkway and Reading stations, the operating speed is 125 mph.
- In South Wales, the operating speed is generally between 70 and 100 mph.
- Only the 77.4 miles between Cardiff Central and Carmarthen via Swansea is not electrified.
There is probably scope to increase the operating speed using digital signalling and by improving the track.
I would suspect that a time between London Paddington and Carmarthen of under three-and-a-half hours is possible.
The Range Of Battery-Electric Trains
Hitachi have not been specific about the zero-carbon range of their Intercity Tri-Mode Battery Train, which is described in this Hitachi infographic.
In Stadler FLIRT Akku Battery Train Demonstrates 185km Range, I talk about Stadler’s record-braking Battery-electric; Akku, which covered 185 km or 115 miles.
I suspect that Hitachi’s engineers and those at their battery suppliers; Turntide Technology will be ultra-competitive, so I wouldn’t be surprised that the zero-carbon range of the Hitachi train is very competitive to the Stadler FLIRT Akku.
A hundred mile range would allow electric services to be run on these routes.
- Cardiff and Carmarthen – 77.4 miles
- Chippenham and Bristol Temple Meads and return – 48.8 miles
- Chippenham and Bristol Western-super-Mare and return – 86.9 miles
- Swindon and Cheltenham Spa and return – 86.5 miles
- East Coast Main Line and Hull and return – 72.2 miles
- Plymouth and Penzance – 79.5 miles
- Taunton and Newbury – 89.6 miles
- York and Scarborough and return – 84.1 miles
I am fairly sure that Hitachi will aim for at least a hundred mile battery range for their Intercity Tri-Mode Battery Train.
- This would be competitive with other train manufacturers like Stadler and Siemens.
- They would handle a lot of important routes.
- With development they could probably handle Edinburgh and Inverness.
I can’t wait to have a ride.
Hitachi Rail Names Preferred Supplier For Battery System Development For UK Trial
The title of this post is the same as that of this article on Rail Technology Magazine.
These are the first two paragraphs.
Hitachi Rail UK is continuing its commitment to electrification and sustainability as it has teamed with a UK based Technology firm to design and supply its traction and battery systems for its intercity battery train trial which it hopes to run in the future.
Working with the North East England Partnership and Turntide Technologies, Hitachi UK Rail are working towards a UK trial for its battery technology which is engineered to reduce emissions and fuel costs. It is hoped, that if successful, it’ll advance the UK’s position as a global leader in battery train technology.
Note.
- Turntide Technologies took over Hyperdrive Innovation.
- Turntide Technologies have designed and built systems for JCB.
Up until now, we have been told very little about the batteries.
I have the following questions.
Is The Battery System In The Class 803 Trains For Lumo By Turntide Technologies/Hyperdrive Innovation?
The Wikipedia entry for Lumo, says this about the design of the Class 803 train.
Services are operated by a fleet of 125 mph (200 km/h) Class 803 electric multiple unit trains, ordered in March 2019 at a cost of £100 million, financed by the rail leasing company Beacon Rail.[15] While based on the same Hitachi AT300 design as the Class 801 Azuma trains operated on the East Coast Main Line by franchised operator London North Eastern Railway (LNER), they are not fitted with an auxiliary diesel engine, but instead feature batteries intended solely to power onboard facilities in case of overhead line equipment failure.
The maker of the batteries has not been disclosed.
If they have been made by Turntide, then they would certainly have had a good vibration testing.
Is The Battery System In The Class 803 Trains Similar To That Proposed For Class 800/802/805/810 Trains?
It would seem sensible, as this would mean that Hitachi would only be introducing one type of battery into the various fleets.
Supporting structures and wiring harnesses would then be identical in all trains, whether diesel engines or batteries were to be fitted.
Are The Batteries Plug Compatible With Similar Performance To The Diesel Engines?
I have never driven a train, but I have ridden in the cab of an InterCity 125, as I wrote about in Edinburgh to Inverness in the Cab of an HST.
The driver controls the two locomotives individually, just like I controlled the two engines in my Cessna 340 with two separate throttles.
So how does a driver control all the three engines in a five-car Class 800 train or the five engines in a nine-car?
Put simply, the driver just tells the computer, what speed or power is required and the train’s computer adjusts al the engines accordingly.
I believe it would be possible to design battery packs that are plug-compatible with similar performance to the diesel engines.
Hitachi could be playing an old Electrical/Electronic Engineer’s trick.
As a sixteen-year-old, I spent a Summer in a rolling mills, building replacement transistorised control units for the old electronic valve units. They had been designed, so they were plug-compatible and performed identically.
The great advantage of this approach, is that no changes were needed to the rolling mill.
So if Hitachi are using a similar approach, there should be very few or even no changes to the train.
What Range Will A Class 800 Train Have On Batteries?
This article on Focus Transport is entitled 224-kilometre Battery Range For FLIRT Akku – Stadler Sets World Record For Guinness Book Of Records.
I would be very surprised if Hitachi don’t break that record of 224 kilometres or 139 miles.
Conclusion
I belive we’re going to see a real revolution in rail transport.
The Ways First Group, Hitachi, Hyperdrive Innovation and Turntide Technologies Can Enable Electric Trains To Run Between Basingstoke And Exeter
Who Are Turntide Technologies?
The Wikipedia entry for the company starts with this paragraph.
Turntide Technologies is a US-based business that makes intelligent, sustainable motor systems. Turntide applies its Technology for Sustainable Operations across buildings, agriculture, and transportation segments. It maintains operations in the USA, Canada, the United Kingdom, and India.
These three paragraphs from the Technology section of the Wikipedia entry outline their technology.
Turntide’s core product is its Technology for Sustainable Operations, a cloud-based open platform that monitors and automates building and vehicle systems. The platform is powered by its Smart Motor System, a connected hardware-software machine built around a high rotor pole switched reluctance motor.
Southern California Edison utility certified in 2018 that the V01 Smart Motor System reduced energy consumption by 23%-57% compared with a standard AC induction motor, and 11% compared with an induction motor controlled by a variable frequency drive.
In 2019, National Renewable Energy Laboratory certified that Turntide’s motor reduced energy consumption in refrigerator condenser fans by 29%-71%.
Note.
- Turntide’s efficiencies, which appear to have been verified by reputable organisations, if they can be reproduced in traction systems for battery-powered transport could improve range substantially.
- There are also other more efficient electric motors being developed.
- I wrote about Norfolk-based advanced traction motor company; Equipmake in Equipmake Hybrid To Battery Powered LT11.
- Motors like these, are the engineer’s cure for range anxiety.
I have to ask, if Hitachi (, and Stadler) are using more efficient motors to stretch the range of their battery-electric trains.
Initially, Hitachi asked Hyperdrive Innovation to design battery packs for Class 802 and other similar trains.
These three posts give some details about the battery project involving the two companies.
- Hitachi And Eversholt Rail To Develop GWR Intercity Battery Hybrid Train – Offering Fuel Savings Of More Than 20%
- Hitachi Rail And Angel Trains To Create Intercity Battery Hybrid Train On TransPennine Express
- More On Batteries On Class 802 Trains
Consider.
- In June 2021, Turntide acquired Hyperdrive Innovation.
- So did this effectively invite Turntide to the project?
- According to the Internet, Hitachi are one of the largest manufacturers of electric motors.
- Turntide are very-well funded by the likes of Bill Gates, Robert Downey Junior and some big funds.
Has there been some intense design meetings, which have been beneficial to all parties?
In my experience, these groupings don’t often work out how they should!
But this relationship seems to be doing fine.
One of Hitachi’s managers from the battery-train project even appears in the video on Turntide’s home page.
Electrifying Basingstoke And Exeter
Consider these facts about the route.
- Basingstoke and Salisbury is 35.8 miles.
- Salisbury and Exeter is 88.5 miles.
- Basingstoke and Exeter is 124.3 miles.
- There is no electrification.
- There are 14 stops between Salisbury and Exeter.
- There are 4 stops between Basingstoke and Salisbury.
- Trains are up to nine car Class 159 trains.
- Average speeds are not much better than 50 mph.
- Maximum speeds vary between 75 and 90 mph.
To get an estimate of how much energy, a Basingstoke and Exeter train will use, I’ll start with a figure from How Much Power Is Needed To Run A Train At 125 Or 100 mph?.
At 125 mph, a Class 801 train has a usage figure of 3.42 kWh per vehicle mile.
As drag is proportional to the square of the speed, which gives
- At 100 mph, a Class 801 train has a usage figure of 2.19 kWh per vehicle mile.
- At 80 mph, a Class 801 train has a usage figure of 1.40 kWh per vehicle mile.
For this calculation I’ll take the 80 mph figure of 1.40 kWh per vehicle mile.
Assuming a five-car train travelling between Basingstoke and Exeter, which is 124.3 miles gives a figure of 870 kWh.
But this is only one use of energy on the train.
- Every time, the train accelerates it will need power, but it will charge itself using regenerative braking.
- An all-electric Class 803 train has a mass of 228.5 tonnes and carries 400 passengers.
- If I assume that each passenger is 80 Kg including baggage, bikes and buggies, that gives a mass of 32 tonnes or a total mass of 260.5 tonnes.
- Putting these figures into Omni’s Kinetic Energy calculator gives a figure of 46.3 kWh at 80 mph.
As there are eighteen stops along the route and at each stop it could lose up to twenty percent of its energy, this means that the eighteen stops will cost 166.7 KWh.
Adding this to the 870 KWh it takes to maintain speed, it looks like a trip between Basingstoke and Exeter will take 1036.7 kWh.
Could this be a 200 kWh battery in each coach?
Obviously, this is only a rough calculation and with the better figures Hitachi would have, I would suspect much better answers.
But I do believe that it would be possible to run between Basingstoke and Exeter on battery power, if the train was efficient.
Charging The Train
The train would be charged on the third-rail electrification between Waterloo and Basingstoke.
But what would happen at Exeter?
The trains could be bi-modes like Hitachi’s Class 395 trains for Southeastern,
One of Vivarail’s third-rail charging systems, that First Group, acquired from the Receiver of Vivarail could be used.
Getting The Order Right
Would between Basingstoke and Exeter, be a sensible route to convert to battery-electric trains early, as it would release a useful fleet of diesel trains, that might be able to fill in for a couple of years by replacing the Castles!
