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.

- 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.
Devizes Station Would Need To Be Part Of Wider Rail Plan
The title of this post, is the same as that of this article on Railway Gazette.
These two paragraphs outline the current status.
The construction of a Devizes Gateway station at Lydeway is unlikely to represent value for money as a standalone project, but it could be viable as part of a wider rail improvement programme, a study has concluded.
The feasibility study undertaken by Wiltshire Council, Devizes Development Partnership, GWR and Network Rail built on a strategic outline business case submitted to the Department for Transport under the Restoring Your Railway Fund programme in November 2021.
The Department for Transport will now decide what to do next.
I think there are other issues on the route between Reading and Taunton.
The Current Train Service
The only passenger services using the Reading and Taunton route are these three trains, which all have a frequency of one train per two hours (tp2h).
- London Paddington and Exeter St. Davids – Calling at Reading, Newbury, Hungerford, Pewsey, Westbury, Castle Cary, Taunton and Tiverton Parkway
- London Paddington and Plymouth – Calling at Reading, Taunton, Tiverton Parkway and Exeter St Davids
- London Paddington and Penzance – Calling at Reading, Taunton, Tiverton Parkway and Exeter St Davids
Note.
- London Paddington and Exeter St. Davids takes a few minutes over two hours.
- London Paddington and Plymouth takes a few minutes over three hours.
- London Paddington and Penzance takes a few minutes over five hours.
- The Reading and Taunton route is a double-track railway with a 110 mph operating speed.
- London Paddington and Newbury is electrified.
- The last two trains alternate to give Plymouth an hourly service.
- After Exeter St. Davids, trains have a sophisticated stopping pattern to give all stations served a good service.
From several trips along the line, I have the impression, that it’s a route, where drivers can get the best out of the trains.
Electrification
The line would benefit from electrification, in terms of journey times and decarbonisation.
But could this route be run by battery-electric trains?
- It is 89.7 miles between Newbury and Taunton.
- It is 120.4 miles between Newbury and Exeter St. Davids.
- It is 52.1 miles between Exeter St. Davids and Plymouth.
- It is 79.4 miles between Plymouth and Penzance.
- London Paddington and Newbury is electrified.
- Taunton, Exeter St. Davids, Plymouth and Penzance stations could have a charging system of some sort.
This Hitachi infographic shows the specification of the Hitachi Intercity Tri-Mode Battery Train.
Consider.
- Two trains go between Newbury and Taunton without stopping.
- The Exeter St. Davids service stops three times.
- Newbury and Taunton non-stop took 75 minutes at an average speed of 72 mph
- Newbury and Taunton with three stops took 78 minutes.
- All trains currently appear to be nine cars.
I suspect that Hitachi’s Intercity Tri-Mode Battery Train could go between Newbury and Taunton with a great deal of ease.
How many diesel engines and batteries would the train have?
Normally, nine-car Class 800/802 trains have five diesel engines.
So how many will be replaced by batteries?
The infographic says one engine will be replaced, so if that is a five-car train, it looks likely that a nine-car train could have two batteries.
But Hitachi could be playing a long game!
In Stadler FLIRT Akku Battery Train Demonstrates 185km Range, I wrote about how the FLIRT Akku has a range of 115 miles.
If Hitachi can squeeze 125 miles out of a nine-car Class 800 with two or three battery packs, they will outrange the FLIRT Akku and be able to run between London Paddington and Penzance on batteries, with some topping up on the way.
We mustn’t forget the engineers at Hyperdrive Innovation, who are designing and building Hitachi’s battery packs.
They will be ultracompetitive and know the range required to get battery-electric trains to Penzance.
I suspect that when the range of the nine-car battery-electric Class 800/802 is revealed, it will astonish everybody!
Bedwyn Station
Bedwyn station is served by an hourly shuttle train to and from Newbury, run by a diesel train.
The station used to have a direct service from London, but now passengers change at Newbury.
A Station For Marlborough
I investigated this in A Station For Marlborough, where this was my conclusion.
With the next generation of electric train with onboard energy storage or IPEMUs, a Marlborough station on a new Marlborough Branch Line can be used to create a two tph service to and from Paddington to replace the current one tph service from Bedwyn.
So a new Marlborough station would be a win for all those using stations on the Reading to Taunton Line to the East of Pewsey.
I also wonder how many other similar services can be developed by extending a service past a main line terminal to a new or reopened branch line, which is built without electrification and run using trains with onboard energy storage.
In answer to my posed question in the last paragraph, I suspect it is quite a few!
Devizes Gateway Station At Lydeway
I wrote about this proposed Devizes Gateway station in Reinstatement Of Rail Access To Devizes Via A New Station At Lydeway.
After writing Was Baldrick An Essex Man? about the building of an avoiding line at the new Beaulieu Park station North of Chelmsford, I do wonder, if it would be an idea to incorporate one in this proposed station, if there is a need to increase capacity.
This Google Map shows the station site, where the A342 crosses the railway.
I suspect a third track can be squeezed in.
Westbury Station
Westbury station is a busy station, where the Reading and Taunton Line crosses the Wessex Main Line.
This map from OpenRailwayMap shows the lines in the station.
Note.
- The blue lettering indicates Westbury station.
- The two major rail routes are shown in orange.
- The Reading and Taunton Line goes East-West across the map.
- Note the avoiding line South of Westbury station.
- Reading is in the East and Taunton is in the West.
- The Wessex Main Line goes North-South across the map.
- Bristol is in the North.
- Salisbury and Southampton is in the South.
In Westbury Station – 30th July 2020, there are some pictures I took of Westbury station.
This section in Wikipedia says this about the Future of Westbury station.
The line to Westbury is not due to be electrified as part of the 21st-century modernisation of the Great Western Main Line. Although local councillors support it, the extension of electrification beyond Newbury to Westbury was assessed as having a benefit–cost ratio of only 0.31.
On the other hand this document on the Network Rail web site, which is entitled the Devizes Gateway Interim
Feasibility Study, suggests that another platform might be added at Westbury station.
Castle Cary Station
Castle Cary station doesn’t seem to have any well-publicised problems, so please tell me if you know of any.
Frome Station
Frome station is described in its Wikipedia entry as an unusual station and one that is Grade II Listed.
I suspect, it could do with some more services.
Somerton Station
I wrote about a new Somerton station in Somerset: Plans For New Railway Station On Levels.
Track Improvements
I suspect if Network Rail were improving the route between Reading and Taunton, they know of some places, where they could do some work.
Service Improvements
Consider.
- There is probably a need for a stopping train between Newbury and Taunton, which calls at all stations.
- It might terminate at the London end, at either London Paddington or Reading.
- It might be a battery-electric train.
- An hourly frequency would be ideal, if the track and signalling could handle it.
- Charging systems would be positioned as needed.
The train would interface with other Great Western services to Bristol, London Paddington, Gloucester, Salisbury, Southampton and Weymouth.
Oy could also interface with the Transwilts services.
Conclusion
This could be developed into a very useful network for Wessex.
Partnership To Develop North American Battery Train
The title of this post, is the same as that of this article on Railway Gazette.
This is the first paragraph.
A contract for the development and testing of a battery multiple-unit for the North American market based on Stadler’s Flirt Akku design for Europe has been signed by the Swiss manufacturer, Utah State University and the Advancing Sustainability through Powered Infrastructure for Roadway Electrification engineering research centre.
After my recent visit to Liverpool, after which I wrote Riding In A Train Designed To Run On Battery Power, I am certainly of the belief that Stadler know where they are going.
Skegness Station To Benefit From A £3.3m Improvement Package
The title of this post, is the same as that of this article on Rail Technology Magazine.
I took these pictures of Skegness station, on a visit to the town in July last year, which I wrote about in A Trip To Skegness.
I feel that Skegness station would welcome some improvement.
The Rail Technology Magazine article says this about the project.
Upon completion of the project, customers will be able to utilise a number of enhanced facilities, including an improved accessible toilet with changing spaces, two new start-up offices, a community café and retail provisions. Upgrades will continue through improved access into the station for pedestrians and vehicles, offering integration with the surrounding community.
Work is hoped to start this year.
A Modern Zero-Carbon Train Service
If £3.3 million is going to be spent on Skegness station, would it not be a good idea to have better trains serving the station.
In A Trip To Skegness, I talked about updating the hourly Nottingham and Skegness service using Class 170 trains with Rolls-Royce MTU Hybrid PowerPacks.
I wonder if this route could be improved by fitting the Class 170 trains with Rolls-Royce MTU Hybrid PowerPacks?
- The hybrid technology would have a lower fuel consumption and allow electric operation in stations.
- The prototype hybrid is already working on Chiltern Railways in a Class 168 train.
- The Class 168 train is an earlier version of the Class 170 train and they are members of the Turbostar family.
- Rolls-Royce are developing versions of these hybrid transmissions, that will work with sustainable fuels.
- As we have a total of 207 Turbostar trainsets, these could be a convenient way of cutting carbon emissions on long rural lines.
- As Rolls-Royce MTU are also developing the technology, so their diesel engines can run on hydrogen, it is not outrageous to believe that they could be on a route to complete decarbonisation of this type of train.
I believe that we could see hydrogen-hybrid Class 170 trains, with a Rolls-Royce badge on the side.
But would it be possible to go the whole way using one of Stadler’s battery-electric trains?
Consider the service between Nottingham and Skegness.
- It is hourly.
- The route is run by 100 mph Class 170 trains.
- Nottingham and Grantham are 22.7 miles apart.
- Grantham and Skegness are 58.2 miles apart.
- Trains take four minutes to reverse at Grantham.
- Trains wait 20 minutes before returning at the two end stations.
- Trains reverse at Nottingham in a bay platform, which is numbered 2.
- Grantham is electrified.
- Nottingham station will be electrified in the next few years.
- Skegness station is next to the bus station in the middle of the town, so hopefully the electricity supply is robust enough to charge buses and trains.
Stadler make a train called an Akku.
- It is a member of the FLIRT family.
- It is a 100 mph train.
- I wrote Stadler FLIRT Akku Battery Train Demonstrates 185km Range, which means it could run between Nottingham and Skegness without intermediate charging.
This leads me to the conclusion that with charging systems at Nottingham and Skegness and taking a four-minute top-up at Grantham if needed, a FLIRT Akku could handle this route with ease.
Conclusion
Skegness is a town that needs leveling-up. A refurbished station and 100 mph electric trains to Grantham and London would be a good start.
Regulator Approves New Grand Union Train Service From Carmarthen To London Paddington
The title of this post, is the same as that of this press release from the Office of Rail and Road.
This is the sub-heading of the press release.
The Office of Rail and Road (ORR) has opened up the Great Western Main Line to competition and enabled a significant increase in rail services between London and South Wales.
These points are made in the press release.
- The rail regulator has approved the introduction of new train services between London, Cardiff and South West Wales from the end of 2024.
- The services will be operated by a new open access operator, Grand Union Trains, bringing competition to the Great Western route out of Paddington.
- Passengers travelling between London, Bristol Parkway, Severn Tunnel Junction, Newport, Cardiff, Gowerton, Llanelli and Carmarthen will benefit from an extra five daily return services and greater choice of operator.
- The decision opens up the Great Western Main Line to competition for the first time, with potential benefits in terms of lower fares, improved service quality and innovation for all passengers using the route.
- The application, submitted to ORR in June 2022, was disputed by Network Rail due to concerns about capacity on the network. But following careful consideration and analysis, ORR has directed Network Rail to enter into a contract with Grand Union.
- Grand Union has committed to significant investment in new trains.
- As an ‘open access’ train operator, however, it will not get paid subsidies from public funds, unlike current operators along the route.
ORR supports new open access where it delivers competition for the benefit of passengers. In making this decision, the regulator has weighed this up against the impact on Government funds and effect on other users of the railway, both passengers and freight customers.
These are my thoughts.
The Company
Grand Union Trains have certainly persevered to get this approval.
- The company was created by Ian Yeowart, who previously created open access operators; Alliance Rail Holdings and Grand Central before selling both to Arriva.
- After multiple negotiations with the Office of Road and Rail (ORR), Yeowart must know how to get an acceptable deal.
- Grand Union Trains have a similar application for a service between Euston and Stirling with the ORR.
Grand Union Trains also have a web site.
The home page has a mission statement of Railways To Our Core, with this statement underneath.
At Grand Union we are passionate about Britain’s railways. We are committed to the traditional values of providing a high-quality customer service and a comfortable journey experience at a fair price.
I’ll go with that.
The Financial Backing Of The Company
All the UK’s open access operators are well-financed either by Arriva or First Group.
The ORR would not receive any thanks, if they approved an operator, which duly went bust.
So what is the quality of the financing behind Grand Union Trains?
This article on Railway Gazette is entitled RENFE Looks At Entering UK Rail Market Through Open Access Partnership, which starts with this paragraph.
Open access passenger service developer Grand Union Trains is working with Spain’s national operator RENFE and private equity firm Serena Industrial Partners on a proposed service between London and Wales.
That is fairly clear and would surely help in the financing of Grand Union Trains.
The Route
Trains will run between Carmarthen and London Paddington, with stops at Llanelli, Gowerton, Cardiff, Newport, Severn Tunnel Junction and Bristol Parkway.
A new station at Felindre will replace Gowerton at some time in the future.
There will be five trains per day (tpd).
I have some thoughts and questions about the route
Felindre Station
Felindre station is named in Wikipedia as the West Wales Parkway station, where it is introduced like this.
West Wales Parkway is a proposed railway station north of Swansea, near to the boundaries of the neighbouring principal area of Carmarthenshire, and the villages of Felindre and Llangyfelach. The station is proposed to be situated at the former Felindre steelworks, near Junction 46 of the M4 and A48, and near Felindre Business Park and Penllergaer Business Park. The project is in the planning stages, as part of a wider Department for Transport proposal to re-open the Swansea District line to passenger traffic.
This Google Map shows where, it appears the Felindre station will be built.
Note.
- The Felindre Business Park in the North-West corner of the map, with a Park-and-Ride.
- The M4 running across the bottom of the map.
- The Swansea District Line runs East-West between the motorway and the Business Park.
It looks that the new station could be located on the South side of the Business Park.
When High Speed Two Opens Will Trains Call At Old Oak Common?
When High Speed Two opens, all GWR trains will stop at Old Oak Common station for these connections.
- Chiltern for for Banbury, Bicester, High Wycombe and the West Midlands
- Elizabeth Line for Central and East London and the Thames Valley
- Heathrow Airport
- High Speed Two for Birmingham and the North
- Overground for Outer London
As Old Oak Common will be such an important interchange, I think they should.
Will The Platforms At Carmarthen Station Need Lengthening?
This Google Map shows Carmarthen station.
Note.
- The station has two platforms.
- There are certainly pictures of the station with an InterCity 125 in the station. There is a picture on the Wikipedia entry for Carmarthen station.
These pictures show the station.
I suspect that the station will be upgraded to accommodate Grand Union Trains.
The Trains
An article in the June 2022 Edition of Modern Railways, which is entitled Grand Union Bids For London To Carmarthen, gives these details of the trains.
- Three classes.
- 2023 start for the service.
- Cycle provision.
- Vanload freight will be carried.
- Electric trains could start between London and Cardiff by 2023.
- In 2025, trains could be nine-car bi-modes.
- South Wales-based operation and maintenance.
- 125 full-time jobs created.
It certainly seems to be a comprehensive and well-thought out plan.
I have a few thoughts on the trains.
What Make Of Trains Will Be Procured?
Consider.
- Lumo’s Class 803 trains were ordered from Hitachi in March 2019 and entered service in October 2021.
- So if they ordered their version of the Hitachi trains by the end of 2022, the trains could be in service by July/August 2025.
- It would probably be easier, if the only fast trains on the Great Western Main Line between London and South Wales were all Hitachi trains with identical performance.
But the Spanish backers of Grand Union Trains may prefer Spanish-designed trains assembled in South Wales. So would a bi-mode version of CAF’s Class 397 trains be suitable?
On the other hand, the Carmarthen and Cardiff section of the route without a reverse at Swansea is only seventy-five miles.
This Hitachi infographic shows the Hitachi Intercity Tri-Mode Battery Train.
Consider.
- Charging could be provided at Carmarthen using a short length of electrification or one of Furrer + Frey standard chargers.
- Charging would also use the electrification between London Paddington and Cardiff.
- A nine-car Class 800 or Class 802 train has five engines and a five-car train has three engines.
- The Intercity Tri-Mode Battery Train was announced in December 2022.
- In the intervening two years how far has the project progressed?
- For the last twelve months, Lumo have been running trains with an emergency battery-pack for hotel power. How are the batteries doing, whilst being ferried up and down, the East Coast Main Line?
Can Hitachi configure a train with more than one battery-pack and a number of diesel engines, that has a range of seventy-five miles? I suspect they can.
I suspect that CAF also have similar technology.
There is also a benefit to Great Western Railway (GWR).
If GWR were able to fit out their Class 802 trains in the same way, they would be able to run between Cardiff and Swansea on battery power.
- It is only 45.7 miles.
- Charging would need to be provided at Swansea.
- GWR could still run their one tpd service to Carmarthen.
It looks like both train operating companies could be able to do as Lumo does and advertise all electric services.
What Could Be The Maxmum Range Of A Hitachi Train On Batteries?
This Hitachi infographic shows the Hitachi Regional Battery Train.
Consider.
- It has a battery range of 90 km or 56 miles on the single battery.
- I would expect that by a regional train, Hitachi mean a five car Class 800 or 802 train, like those that go to Cheltenham, Lincoln or Middlesbrough.
- A five-car Hitachi Regional Battery Train would have a battery that could contain power equivalent to 280 car-miles.
- Five-car Class 800 or 802 trains have three engine positions.
- These Hitachi trains have a very sophisticated control system, which I wrote about in Do Class 800/801/802 Trains Use Batteries For Regenerative Braking?
I believe the engineers at Hyperdrive Innovation have designed the battery-packs that replace the diesel engines as simulations of the diesel engines, so they can be a direct replacement.
This would mean that battery-packs could be additive, so the following could apply to a five-car train.
- Two battery packs could have a range of 112 miles.
- Three battery packs could have a range of 168 miles.
GWR generally runs pairs of five-car trains to Swansea, which would be 90 miles without electrification.
If five-car trains with two battery packs, could be given a range of 112 miles, GWR could run an electric service to Swansea.
They could also run to Carmarthen, if Grand Union Trains would share the charger.
What ranges could be possible with nine-car trains, if one battery pack is good for 280 car-miles?
- One battery-pack, gives a range of 280/9 = 31 miles
- Two battery-packs, give a range of 2*280/9 = 62 miles
- Three battery-packs, give a range of 3*280/9 = 93 miles
- Four battery-packs, give a range of 4*280/9 = 124 miles
- Five battery-packs, give a range of 5*280/9 = 155 miles
- Six battery-packs, give a range of 6*280/9 = 187 miles
- Seven battery-packs, give a range of 7*280/9 = 218 miles
Note.
- I have rounded figures to the nearest mile.
- There are five cars with diesel engines in a nine-car train, which are in cars 2,3,5, 7 and 8.
- Diesel engines are also placed under the driver cars in five-car Class 810 trains.
- For the previous two reasons, I feel that the maximum numbers of diesel engines in a nine-car train could be a maximum of seven.
- I have therefor assumed a maximum of seven battery packs.
These distances seem sensational, but when you consider that Stradler’s Flirt Akku has demonstrated a battery range of 243 kilometres or 150 miles, I don’t think they are out of order.
But, if they are correct, then the ramifications are enormous.
- Large numbers of routes could become electric without any infrastructure works.
- Grand Union Trains would be able to run to Carmarthen and back without a charger at Carmarthen.
- GWR would be able to run to Swansea and back without a charger at Swansea.
Prudence may mean strategic chargers are installed.
Rrenewable Energy Developments In South West Wales
In Enter The Dragon, I talked about renewable energy developments in South West Wales.
I used information from this article on the Engineer, which is entitled Unlocking The Renewables Potential Of The Celtic Sea.
The article on the Engineer finishes with this conclusion.
For now, Wales may be lagging slightly behind its Celtic cousin to the north, but if the true potential of the Celtic Sea can be unleashed – FLOW, tidal stream, lagoon and wave – it looks set to play an even more prominent role in the net zero pursuit.
The Red Dragon is entering the battle to replace Vlad the Mad’s tainted energy.
South West Wales could see a massive renewable energy boom.
Grand Union Trains will increase the capacity to bring in more workers to support the developments from South Wales and Bristol.
‘Castle’ HSTs To Be Withdrawn By Great Western Railway
The title of this post, is the same as that of this article on Rail Advent.
This quote from a GWR spokesman, sums up the action that will be taken.
The Castles were always designed to be a temporary measure on the Cardiff to Penzance route. We expect to replace the Castle Class trains on a phased basis over the next couple of years, bringing customers the benefit of more modern trains that will reduce both cost and carbon emissions across the route.
These are my thoughts.
Could The Engines In The Power Cars Be Replaced With Modern Carbon-Neutral Engines?
This would be an alternative way to solve the decarbonisation problem.
It would also mean that other applications of the Class 43 power cars, like ScotRail’s Inter7City trains, Cross Country’s HSTs and Network Rail’s New Measurement Train would have a decarbonisation route,
In Rolls-Royce Releases mtu Rail Engines For Sustainable Fuels, Rolls-Royce mtu outline their route to decarbonise rail engines using sustainable fuels.
This was the first paragraph of my conclusion in the linked article.
Rolls-Royce and Cummins seem to be doing a thoroughly professional job in decarbonising the diesel engines they have made in recent years.
The Class 43 power cars have Rolls-Royce mtu Series 4000 engines, which will soon be available to run on sustainable fuel.
I think as a possible fall-back, one Class 43 power car should be converted to carbon neutral.
Could The Engines In The Power Cars Be Replaced With Modern Hydrogen Engines?
I looked at this in Will We See Class 43 Power Cars Converted To Hydrogen?.
I came to the conclusion, that this might be possible and said this.
It would be the ultimate Roller.
But then Rolls-Royce know about winning battles with large internal combustion engines.
The Option Of New Trains
This quote from a GWR spokesman was fairly definite about new trains, when they said.
The Castles were always designed to be a temporary measure on the Cardiff to Penzance route. We expect to replace the Castle Class trains on a phased basis over the next couple of years, bringing customers the benefit of more modern trains that will reduce both cost and carbon emissions across the route.
What trains could replace the Castles?
- The Cardiff and Penzance route is just short of 250 miles or roughly 400 kilometres.
- Only about 30 miles at the Cardiff end is electrified.
- Trains would need to be able to handle 25 KVAC overhead electrification.
- 125 mph trains will be needed at the Cardiff end.
- Four or five passenger cars will be needed.
- Currently, there are twelve Castles, so I will assume twelve new trains.
As these trains will be lasting up to forty years, they must be zero-carbon, which must mean battery-electric or hydrogen.
Charging Battery-Electric Trains
Consider
- Bristol Temple Meads, Exeter St. Davis and Plymouth are large stations with several platforms. I suspect that a number of Furrer + Frey’s charging stations can be installed along the route.
- The timetable would be adjusted to allow trains to be charged as they stopped to set down and pick up passengers.
- Trains would dwell in the station and then use their 125 mph performance to regain the time.
- I’ve also found a Penzance to Cardiff service, that stopped at Plymouth for fourteen minutes, which is more than enough to charge the batteries.
- Regenerative braking to the batteries would further eke out the range.
- There might also be some extra electrification around Bristol or Exeter.
- Some form of charging would be needed at Penzance.
Note.
- Putting up electrification may mean that it will delay the new trains for a few years.
- Charging stations along the route could probably be installed to a tight timetable.
I believe that with some top-class work, by battery and charger manufacturers, that a battery-electric train could be developed that could run between Cardiff and Penzance.
Thoughts On Hydrogen
Consider.
- The Alstom Coradia iLint train has a range of about 1,000 km. on hydrogen.
- Companies like Airbus, Boeing and a host of rocket makers will improve the storage and safety of hydrogen.
- A range of a 1,000 km. would allow refuelling at one end of the route.
- Trains could be multiple units or a hydrogen-electric locomotive pulling a rake of coaches with a driving van trailer.
I feel that hydrogen would be very feasible as a power source.
Alstom Could Offer A Hydrogen Aventra
Consider.
- Alstom are developing a hydrogen-powered Aventra.
- Bombardier were offering a 125 mph Aventra.
- A typical Aventra like a Class 720 train seats a hundred passengers a car.
A hydrogen Aventra would be feasible.
Hitachi Could Offer A Battery-Electric Or Hybrid AT-300
In 2021, in Hitachi And Eversholt Rail To Develop GWR Intercity Battery Hybrid Train – Offering Fuel Savings Of More Than 20%, I wrote about the announcement of the Hitachi Intercity Tri-Mode Battery Hybrid Train, which is shown in this Hitachi infographic.
Note.
- Batteries replacing an engine to cut fuel usage and reduce carbon emissions.
- First time a modern UK intercity train, in passenger service, will use alternative fuel.
- These Hitachi trains use mtu engines, so I suspect they will be switched to sustainable fuel like HVO.
- The trains are 125 mph and 140 mph with the latest digital signalling.
- Great Western Railway already have 58 five-car Class 800/802 trains and 35 nine-car 800/802 trains.
- They would not need any changing stations or other infrastructure changes.
- Staff retraining would be minimal.
Testing of the prototype of these trains must be getting very close or even underway.
Stadler Could Offer A Battery-Electric Flirt Akku
Consider
- Stadler have run a Flirt Akku on batteries for 243 km.
- Flirt Akkus will go into service soon.
- Flirts have been designed for 125 mph running.
With charging at Cardiff, Bristol, Exeter, Plymouth and Penzance, I believe a Flirt Akku could handle the route.
Are Hitachi Home And Hosed?
I have a feeling that the announcement has been made about retiring the Castles as the prototype Hitachi Intercity Tri-Mode Battery Hybrid Train is under test and is performing well.
So I wouldn’t be surprised to see an order for twelve more Class 802 trains soon.
Flirt Akku And Class 755 Train Compared
This article on Focus Transport is entitled 224-kilometre Battery Range For FLIRT Akku – Stadler Sets World Record For Guinness Book Of Records.
These facts about the record run are given.
- The route was from from Berlin to Warnemünde.
- It appears to have been independently verified.
- The distance was 224 kilometres or 139 miles.
- This distance is more than London to Great Yarmouth via Norwich.
- It is reported that the temperature was around zero, which is not very battery-friendly.
No mention was made in the article of the number of passengers on board or the average speed.
Various articles have stated that the Flirt Akku is a three-car train, but I was not sure, if it included a PowerPack car like the Class 755 train.
So I flew my virtual drone over the route and got this picture.
Compare the front end with this picture of a Class 755 train at Lowestoft.
And the side view with this diagram of the trains, that I clipped from Wikipedia.
I can come to these conclusions.
- The two front ends are very different, although the basic layout of doors and windows appears the same.
- The Akku seems to have a flatter side.
- The Akku lacks the PowerPack of the British train.
It also looks like the Greater Anglia train has better step-free access between between train and platform. But then you never seem to find good step-free access on German trains.
Some extra information and thoughts .
Testing The Flirt Akku
This article on Railvolution is entitled FLIRT AKKU Research Project Completed.
The article comprehensively described the testing process and gave more details of the train.
- The train was running at 140 kph or 87 mph.
- This speed is available from the catenary or battery.
- Battery charging takes twenty minutes.
- The train seats 154 passengers in a 2 + 2 configuration.
The train appears to be roughly the same size and performance as a three-car Class 755 train.
Range On A Battery-Electric Class 755 Train
The battery range needed on various Greater Anglia routes are as follows.
Ipswich and Cambridge – 41.3 miles
- Ipswich and Felixstowe – 15.6 miles
- Ipswich and Lowestoft – 48.9 miles
- Ipswich and Peterborough – 71.2 miles
- Norwich and Great Yarmouth – 18.3 miles
- Norwich and Lowestoft – 23.5 miles
- Norwich and Sheringham – 30 miles
- Norwich and Stansted Airport – 53.7 miles
- Marks Tey and Sudbury – 11.8 miles
Note.
- Cambridge, Ely, Ipswich, Norwich and Peterborough are stations with full electrification.
- I suspect some services will need charging at the remote station.
It looks like to handle all routes will need a train with a range of around 80 miles or around 129 kilometres.
Conclusion
I don’t think that it would be impossible for Stadler to create a battery-electric Class 755 train with enough range.
Stadler FLIRT Akku Battery Train Demonstrates 185km Range
The title of this post, is the same as that of this article on Railway-News.
This is the first paragraph.
Stadler’s offering in the battery-powered rolling stock market, the FLIRT Akku has demonstrated a guaranteed range of 185km, even in energy-intensive conditions, it has been found following a three-year research period.
The range is very good and is over twice what Hitachi are claiming with the Hitachi Regional Battery Train.
I can’t find out many details of the size of a Flirt Akku train, but this article on the International Railway Journal has these details.
- A picture shows a three-car train.
- The trains have a 100 mph operating speed.
- Fifty-five two-car trains are on order for Schleswig-Holstein.
Stadler can also fit batteries into trains like Greater Anglia’s Class 755 trains.
There have been reports of these trains being fitted with batteries in a couple of years to reduce carbon emissions.
