My First Ride In A Class 397 Train – 15th November 2023
I took these pictures during my first ride in a Class 397 train, between Wigan North Western and Liverpool Lime Street stations.
Note.
- Reading the plates, the total weight of the train is 188.4 tonnes.
- There are 268 seats.
- The ride wasn’t bad at all.
- Seats were comfortable.
Build quality was about the same as a Hitachi train.
Grand Central Trains And CAF’s Tri-Mode Trains
In First Tri-Mode Long Distance Trains For The East Coast Main Line, I wrote about LNER’s purchase of a new fleet of ten CAF tri-mode trains to work services between London and Yorkshire.
In this press release from LNER, which is entitled First Tri-Mode Long Distance Trains For The East Coast Main Line, this is a paragraph.
This new fleet of trains will keep LNER on track to reduce its emissions by 67 per cent by 2035 and be net zero by 2045. LNER has already reduced carbon emissions by 50 per cent compared with 2018/19. Per mile, LNER trains produce 15 times less carbon emissions than a domestic flight.
I believe that as they compete over similar routes with LNER, that Grand Central Trains will have to implement a similar decarbonisation strategy or their business will suffer.
The new trains for Grand Central Trains, will need to have the following conditions.
Train Length
Consider.
- The train must be able to fit all the platforms it will use.
- Ten-cars may be too long for some of the platforms.
- Train length should also be long enough to capture as much of the market as possible.
But as adjusting the length of trains is an easy process, I suspect all manufacturers will be happy to supply extra carriages.
Distances Without Electrification
These are the distances on Grand Central Trains’s services without electrification.
- Doncaster and Bradford Interchange – 52.1 miles
- Northallerton and Sunderland – 47.4 miles
A battery-electric train with a battery range of 110 miles would probably be able to reach Sunderland and return, after charging on the main line.
But a CAF tri-mode train, which ran on diesel or a suitable sustainable fuel like biodiesel or HVO wouldn’t give the driver, operator or passengers any worries.
Possible Time Savings To Bradford
Digital signalling is being installed on the East Coast Main Line between Woolmer Green and Dalton-on-Tees, which will allow running on the line up to 140 mph.
- Woolmer Green is 132.1 miles South of Doncaster.
- A typical train time by Grand Central Trains is 75 minutes.
- This is an average speed of 110 mph.
- Trains take typically three hours and eight minutes between London and Bradford Interchange.
I can build a table of timings and savings at various average speeds.
- 120 mph – 66 minutes – 9 minutes
- 125 mph – 63 minutes – 12 minutes
- 130 mph – 61 minutes – 14 minutes
- 140 mph – 57 minutes – 18 minutes
Several times, I have timed an Hitachi train running at 125 mph on routes like the East Coast Main Line, Great Western Main Line, Midland Main Line and West Coast Main Line, so I have no doubt, that London and Bradford Interchange services can be less than three hours.
These journey time savings will be available to any train able to use the digital electrified railway to the South of Doncaster.
Possible Time Savings To Sunderland
Dalton-on-Tees, where the first phase of the digitally signalling will end, is North of Northallerton, so once the Sunderland train is on the East Coast Main Line, it will be a digital electrified railway all the way to Woolmer Green.
- Woolmer Green is 194.6 miles South of Northallerton.
- A typical train time by Grand Central Trains is 151 minutes.
- This is an average speed of 77.3 mph.
- Trains take typically three hours and twenty-eight minutes between London and Sunderland.
I can build a table of timings and savings at various average speeds.
- 120 mph – 97 minutes – 54 minutes
- 125 mph – 93 minutes – 58 minutes
- 130 mph – 89 minutes – 62 minutes
- 140 mph – 83 minutes – 68 minutes
It looks like times of two hours and thirty minutes will be possible between between London and Sunderland.
Will The Trains Need A 140 mph Capability?
Trains will need to average 125 mph on the digital electrified East Coast Main Line to get under three hours for Bradford Interchange and 2½ hours for Sunderland, so I feel a 140 mph capability is required between Northallerton and London.
Could The Trains Split And Join At Doncaster?
High speed paths on the digitally signalled and electrified East Coast Main Line might be at a premium, so running pairs of five-car trains to two destinations could be commonplace working.
- It could be a way of increasing frequency to Bradford Interchange and Sunderland, by perhaps running pairs of five-car trains that split at Doncaster.
- Grand Union Trains have proposed in the past to use splitting and joining to run services to Cleethorpes.
As Hitachi trains can split and join, I suspect that the CAF tri-mode trains will be at least able to be retrofitted with the ability.
Conclusion
These are my conclusions.
- The digital signalling certainly gives good time saving to Yorkshire and the North-East
- New trains for Grand Union Trains would give them faster services on their existing routes.
- Trains with a 140 mph capability would be needed.
- CAF tri-mode trains wouldn’t need any new infrastructure, but battery-electric trains may need chargers at the destinations.
- Because of the lower infrastructure requirements, I think the CAF trains will get the nod.
First Tri-Mode Long Distance Trains For The East Coast Main Line
The title of this post, is the same as that of this press release from LNER.
This is the sub-heading.
London North Eastern Railway (LNER) is pleased to confirm that CAF has been named as the successful bidder to deliver a fleet of 10 new tri-mode trains for LNER. Porterbrook has been chosen as the financier of the new fleet. The trains will be able to operate in electric, battery or diesel mode.
These are the first two paragraphs.
Benefits of tri-mode trains range from a reduction in emissions, particulates, noise and vibration pollution, lower maintenance and operating costs and upgradeable technology, with an expected increase in range and performance as technology develops further. Battery power reduces the need to use diesel traction in areas where overhead powerlines are not available.
Complementing the modern Azuma fleet of 65 trains, the new ten-coach trains will help LNER achieve its vision of becoming the most loved, progressive and trusted train operator in the UK, delivering an exceptional service for the customers and communities served along its 956-mile network.
I have a few thoughts.
Will The Trains Have Rolls-Royce mtu Diesel Engines?
Consider.
- CAF’s Class 195, 196 and 197 Civity trains for the UK all have Rolls-Royce mtu diesel engines.
- Porterbrook are headquartered in Derby.
- Rolls-Royce are headquartered in Derby.
- In Rolls-Royce And Porterbrook Agreement Will Drive Rail Decarbonisation, I talked about how the two companies were planning to decarbonise trains using techniques like mtu Hybrid PowerPacks and hydrogen fuel cells.
I would think it very likely that the new trains will have Rolls-Royce mtu engines.
Will The Trains Have Rolls-Royce mtu Hybrid PowerPacks?
It was in 2018, that I first wrote about mtu Hybrid PowerPacks in Rolls-Royce And Porterbrook Launch First Hybrid Rail Project In The UK With MTU Hybrid PowerPacks.
- Examples of these power packs are now running in Germany, Ireland and the UK.
- The mtu Hybrid PowerPack how has its own web site.
- There is also this YouTube video.
- If CAF use off-the-shelf mtu Hybrid PowerPacks in their Civity trains, there is one big massive plus – They don’t have to develop the complicated control software to get a combination of diesel engines and batteries to perform as immaculately as Busby Berkeley’s dancers or a Brigade of Guards.
- The mtu Hybrid PowerPacks also have a big plus for operators – The batteries don’t need separate charging infrastructure.
- In Rolls-Royce Releases mtu Rail Engines For Sustainable Fuels, I talk about how mtu engines can run on sustainable fuels, such as biodiesel or HVO.
I think it is extremely likely that CAF’s new trains for LNER will be powered by mtu Hybrid PowerPacks.
Class 800 And Class 397 Trains Compared
The Class 800 train is LNER’s workhorse to Scotland from London.
The Class 397 train used by TransPennine Express, is a 125 mph Civity train.
Differences include.
- The Class 800 train can run at 140 mph, where the signalling allows, but is the Class 397 train only capable of 125 mph?
- The Class 397 train accelerate at 0.92 m/s², whereas the Class 800 train can only manage 0.7 m/s².
- The Hitachi train has 14 % more seats, 36 First and 290 Standard as opposed to 22 First and 264 Standard in five-car trains.
I will add to this list.
Will The New Trains Be Capable Of 140 mph Running?
As the East Coast Main Line is being fully digitally signalled to allow 140 mph running of the numerous Hitachi expresses on the route, I wouldn’t be surprised to see, that the new CAF trains will be capable of 140 mph.
In this article on Modern Railways, which is entitled LNER Orders CAF Tri-mode Sets, this is said.
The new fleet will be equipped with CAF Signalling’s European Rail Traffic Management System digital signalling. This will align with the East Coast Digital Programme, which aims to introduce European Train Control System (ETCS) on the southern stretch of the East Coast main line from King’s Cross to Stoke Tunnel by 2029.
Later in the article this is said.
LNER has retained 12 ‘91s’ hauling eight rakes of Mk 4s, and the rollout of ETCS is another reason the operator has sought to order the replacement fleet. LNER’s passenger numbers have rebounded more quickly than other operators post-Covid, which has helped make the case for confirming the order.
This does seem sensible.
What Will Be The Range Of The CAF Trains Without Electrification?
The longest LNER route without electrification is the Northern section of the Inverness service between Inverness and Dunblane, which is 146.1 miles. There are also eight stops and some hills.
In Edinburgh to Inverness in the Cab of an HST, there’s a video of the route.
I’m sure that even, if they don’t normally run the new trains to Inverness, being able to do so, could be useful at some point.
It should be noted that the Guinness World Record for battery-electric trains is 139 miles, which is held by a Stadler Akku.
I am left with the conclusion that London and Inverness needs a tri-mode train or lots of electrification. Did this rule out Hitachi?
The Number Of Trains Ordered
The Modern Railways article says this about the number of trains.
The contract includes an eight-year maintenance services agreement with an option to extend; CAF says the order value, including maintenance, exceeds €500 million. When the tender was published the intention was to include an option for five additional sets; LNER confirmed to Modern Railways there is an option to purchase additional sets on top of the base order of 10.
Can we assume this means that other trains will be ordered, if the trains are a success?
Can These New CAF Trains Be Made Net Zero?
This is a paragraph, in the LNER press release.
This new fleet of trains will keep LNER on track to reduce its emissions by 67 per cent by 2035 and be net zero by 2045. LNER has already reduced carbon emissions by 50 per cent compared with 2018/19. Per mile, LNER trains produce 15 times less carbon emissions than a domestic flight.
As the new CAF trains will probably have a service life of at least forty years, there must be some way, that these new trains can be made net zero.
Consider.
- I am absolutely certain, that the new CAF trains will have Rolls-Royce mtu diesel engines.
- LNER’s existing Class 800 and 801 trains have Rolls-Royce mtu diesel engines.
Rolls-Royce mtu according to some of Rolls-Royce’s press releases appear to be developing net zero solutions based on hydrogen or net zero fuels.
This press release from Rolls-Royce is entitled Rolls-Royce Successfully Tests mtu Engines With Pure Hydrogen, suggests that Rolls-Royce mtu are working on a solution.
Routes They Will Serve
The Modern Railways article says this about the routes to be served.
Modern Railways understands the new fleet will be maintained at Neville Hill depot in Leeds and, like the ‘225’ sets, will be used predominantly on services between London and Yorkshire, although unlike the ‘225s’ the tri-modes, with their self-power capability, will be able to serve destinations away from the electrified network such as Harrogate and Hull.
Note.
- This surprised me, as I’d always expected the Yorkshire routes will be served by Hitachi battery-electric trains.
- But it does look that both Harrogate and Hull stations, have long enough platforms to hold a ten-car train.
- With their tri-mode technology, it also looks like the CAF trains won’t be needed to be charged before returning to London.
The last point would enable them to try out new routes.
These are distances from the electrification of the East Coast Main Line of the destinations that LNER served, where there is not full electrification.
- Aberdeen via Ladybank – 91.4 miles
- Carlisle via Skipton – 86.8 miles
- Cleethorpes via Newark and Lincoln – 63.9 miles
- Harrogate via Leeds – 18.3 miles
- Huddersfield via Leeds – 17.2 miles
- Hull via Temple Hirst junction – 36.1 miles
- Inverness via Dunblane – 146.1 miles
- Lincoln via Newark – 16.7 miles
- Middlesbrough via Northallerton – 22.2 miles
- Scarborough via York – 42.1 miles
- Sunderland via Northallerton – 47.4 miles
Note.
- The first place after the ‘via’ is where the electrification ends.
- Carlisle could be a possibility during High Speed Two upgrading of the West Coast Main Line or for an enthusiasts’ special or tourist train.
- Cleethorpes is a possible new service for LNER. I wrote about this in LNER To Serve Cleethorpes.
- Scarborough must be a possible new service for LNER.
- All stations can take ten-car trains, with the possible exception of Middlesbrough, which is currently being upgraded.
- Huddersfield and Leeds is being electrified under the TransPennine Upgrade.
This would appear to show that LNER need enough bi-mode or tri-mode trains to run services to Aberdeen, Cleethorpes, Harrogate, Hull, Inverness, Lincoln, Middlesbrough and Sunderland.
But.
- It would appear that the initial batch of trains, will not be serving the North of Scotland.
- Aberdeen and Inverness could be served, when there is enough electrification at the Southern end.
I am also fairly sure, that no significant infrastructure is required.
Do Hitachi Have A Problem?
I am starting to wonder, if Hitachi are having trouble with the designing and building of their battery packs.
- It’s not like Hitachi to allow someone to run off with a €500 million contract from under their nose.
- Are they short of capacity to build the trains at Newton Aycliffe?
But then they’re probably up to their elbows in work on the High Speed Two Classic-Compatible trains.
Are There Any Other Routes, Where The New CAF Trains Could Be Employed?
The trains would certainly be suitable for these routes.
- Chiltern – InterCity services.
- CrossCountry Trains – Fleet replacement
- Grand Central Trains – Fleet replacement
- Grand Union Trains – For Carmarthen and Stirling open access services.
- Great Western Railway – Replacing Castles in the South West.
- ScotRail – Replacing Inter7City trains.
- South Western Railway – Basingstoke and Exeter St. Davids and other routes.
Note.
- CAF could sell a lot of trains.
- I estimate that fleet replacement for Grand Central Trans would cost around €350 million
- The specification would vary according to the route.
Could CAF have got the LNER order, because they have the capacity in the Newport factory?
Conclusion
It looks like CAF have done a good job in designing the trains.
I’m also fairly sure that CAF are using Rolls-Royce mtu PowerPacks.
TransPennine Express To Stop Using Loco-Hauled Push-Pull Trains In December
The title of this post, is the same as that of this article on Railway Gazette.
This is the sub-heading.
TransPennine Express has confirmed that it will cease using its push-pull sets of Class 68 locomotives and MkVa coaches, previously designated Nova 3 sets, from the December 2023 timetable change.
These are my thoughts.
The Nova 3 Trains
Currently, the Nova 3 trains are made up from the following.
- 14 – Class 68 locomotives
- 52 – Mark 5a coaches
- 14 – Driving Van Trailers
Note.
- There have been complaints about the noise of the Class 68 locomotives at Scarborough and also at Marylebone with Chiltern Railways.
- The Class 68 locomotives could be switched to freight duties.
- The coaches are capable of 125 mph.
- A maximum of thirteen sets can be created.
- I suspect CAF wouldn’t object to being asked to build some more Mark 5a coaches and driving van trailers.
- The current fleet has a spare locomotive and a spare driving van trailer to allow for servicing.
All locomotives and coaches are a maximum of seven years old, so will have plenty of life left.
The Class 93 Locomotive
Rail Operations Group have ordered ten Class 93 locomotives, with twenty options, which have an impressive specification.
- Built by Stadler in Valencia.
- Same family as a Class 68 and 88 locomotive.
- Electric, diesel and battery power
- 110 mph operating speed
- Ability to pull passenger and freight trains.
- Delivery scheduled for 2023.
I believe that if the Class 68 diesel locomotive of a Nova 3 train, were to be replaced with a Class 93 locomotive, a very useful train would be created.
- It would be ten mph faster, than a Nova 3 train.
- It could use the diesel engine and the batteries to bridge gaps in electrification.
- By adding extra carriages it could be tailored to the needs of a route.
- In Vegetable Oil Fuelling Chiltern Railways Trains In UK First, I discuss how it might be possible to run all these locomotives on HVO to cut emissions.
- It could be quieter.
Could it be a simple way to reduce carbon emissions on a route?
The Successor To The Class 93 Locomotive
Stadler keep innovating in their designs for locomotives and are already building hydrogen-powered multiple units.
I can see Stadler coming up with a hydrogen-powered locomotive, with the following specification.
- In the same family as Class 68, 88 and 93 locomotives.
- Ability to do everything that Class 68, 88 and 93 locomotives can do.
- Ability to use 25 KVAC overhead electrification, where it exists.
- Ability to be able to be fitted with third-rail equipment, so it can use 750 VDC third-rail electrification, where it exists.
- At least a 110 mph operating speed.
- Range of at least 200 miles on hydrogen.
Stadler would sell a lot of these locomotives to decarbonise railways all over the world.
Possible Routes
These are possible routes for a rake of Mark 5a coaches hauled by a Class 93 locomotive or its zero-carbon successor.
Hull Trains
Consider.
- Hull Trains is an open access operator.
- Hull Trains currently have a fleet of five Class 802 trains, each of which have five-cars.
- A Class 93 locomotive has a power of 900 kW on diesel, whereas the Class 802 train has 2100 kW.
- The Class 802 train has nearly ten percent more capacity.
- In Ten-Car Hull Trains, I saw two Class 802 trains working as a pair. Does this indicate they have a capacity problem?
- Between Hull and the East Coast Main Line is only 36.1 miles and isn’t very challenging and I suspect could probably be easily handled by a Class 93-hauled rake of Mark 5a coaches.
- Adding extra coaches would not be difficult and would probably be less costly than with the more complex Class 802 trains.
- Hull Trains need to have a plan to decarbonise.
- HVO could be used to cut down emissions.
A Class 93-hauled rake of Mark 5a coaches could be an intermediate step to full decarbonisation with a hydrogen locomotive.
Would other operators of Class 802 trains like to increase their fleets, by adding Hull Trains’s five Class 802 trains?
TransPennine Express
Consider.
- TransPennine Express currently have four different fleets of trains, so it must cause problems with the allocation of drivers.
- The Class 397 trains are confined to the West Coast Main Line.
- So that leaves the bi-mode Class 802 trains and the diesel Class 185 trains to work the TransPennine routes.
The Wikipedia entry for the Class 802 train, gives more details of the plans for the Class 802 trains.
During October 2021, it was announced that TransPennine Express, Hitachi, and Angel Trains had agreed to convert one of the former’s Nova 1 trainsets into a battery hybrid train on a trial basis with the aim of supporting the technology’s further development. If successful, Hitachi and Angel Trains have proposed the retrofitting of the entire fleet. In January 2022, reports emerged that the Nova 1 fleet was operating under diesel power even when operating on entirely electrified sections of the East Coast Main Line on account of the insufficient power supplies present along the line; national railway infrastructure owner Network Rail is reportedly set to complete upgrades to the power supplies within two years.
The fleet is also set to benefit from the rollout of electrification under the Transpennine route upgrade scheme. The company’s management has noted that, in the event of largescale electrification being funded and implemented, the Class 802s could have some of their engines removed to reduce roughly 15% of their weight and thus raise their efficiency. Furthermore, Leo Goodwin, TPE’s managing director, has observed that while the Class 802s have an initial maximum speed of 125 mph (201 km/h), they have the capability of being modified for operating at 140 mph (230 km/h) if infrastructure upgrades were to permit such speeds at a future date.
Could an augmented fleet of battery-electric Class 802 trains handle the bulk of the TransPennine routes, with the shorter and unelectrified ones still being handled by the Class 185 trains?
These shorter routes are.
- Leeds and Huddersfield
- Manchester Piccadilly and Huddersfield
- York and Scarborough
Plans only exist to electrify Leeds and Huddersfield.
I suspect a few more battery-electric Class 802 trains would be needed.
Great Western Railway
Could a Class 93-hauled rake of Mark 5a coaches be used as a replacement for the GWR Castles or short-formation InterCity125s?
- They both have four passenger coaches.
- They are both 125 mph trains.
- A Class 68 locomotive could be used on routes without electrification.
- HVO could be used to cut down emissions.
- The Mark 5a coaches would probably be quieter, as they only have one diesel engine.
A Class 93-hauled rake of Mark 5a coaches could be an intermediate step to full decarbonisation with a hydrogen locomotive.
Alternatively, five-car Class 802 trains could be used as replacements for GWR Castles.
Great Western Railway also have the problem of decarbonising services between Bristol/Gloucester and Weymouth/Southampton/Portsmouth.
Great Western Railway look like they’re needing some innovative thinking.
I also suspect a few more battery-electric Class 802 trains would be needed for other routes.
Transport For Wales Rail
Transport for Wales Rail run a Premier Service between Holyhead and Cardiff using Class 67 locomotives and Mark 4 coaches.
According to the Wikipedia entry for Transport for Wales Rail, they have seven sets of 4/5 coaches to run this service.
If Transport for Wales Rail wanted to decarbonise this route, they would need to replace the locomotives for a zero-carbon unit.
Perhaps, their best solution, would be to wait until a suitable hydrogen-powered locomotive is available and buy seven rakes of new coaches with driving van trailers.
Grand Union
Grand Union has a detailed Wikipedia entry, where this is the first paragraph.
Grand Union is a prospective open access operator who are proposing to operate train services in the United Kingdom from England to Wales and Scotland. Grand Union is headed by Ian Yeowart, who founded previous open access operators Alliance Rail Holdings and Grand Central before selling both to Arriva.
That seems a sound foundation.
- They have permission to run trains between Paddington and Carmarthen starting in December 2024.
- They have also applied to run trains between Euston and Stirling.
- They are now backed by Spanish companies; Serena Industrial Partners and Renfe.
- They are proposing to use nine Mark 4 coaches hauled by Class 93 locomotives.
Consider.
- CAF has a factory in Wales.
- CAF has sold trains to Transport for Wales.
- The Mark 5a coaches will definitely be available by December 2024.
- Mark 5a coaches could easily be arranged as a rake of eight coaches and a driving van trailer.
- Grand Union is backed by Spanish companies.
I wouldn’t be surprised if Grand Union were to use sets of CAF-built Mark 5a coaches for their Carmarthen service. And later for their Stirling service.
A Class 93-hauled rake of Mark 5a coaches could be an intermediate step to full decarbonisation with a hydrogen locomotive.
Grand Central
Consider.
- Grand Central is another open access operator.
- Grand Central has a mixed fleet of twelve five-car diesel trains.
- These trains run under electrification on the East Coast Main Line.
- According to the Wikipedia entry for Grand Central trains, they have plans for expansion across the North and to and from London.
- Grand Central need to have a plan to decarbonise.
- HVO could be used to cut down emissions.
A Class 93-hauled rake of Mark 5a coaches could be an intermediate step to full decarbonisation with a hydrogen locomotive.
South Western Railway
South Western Railway have an excellent fleet of new or nearly new trains, with the exception of the diesel Class 158 and Class 159 trains, that work services between Waterloo and Exeter trains via Basingstoke and Salisbury.
- Waterloo and Exeter is 172 miles.
- Only the 47.7 miles between Waterloo and Basingstoke is electrified with 750 VDC third-rail electrification.
- Train lengths vary between five and eight cars.
- The current trains date from around 1990 and must need replacing soon.
I wouldn’t be surprised that if after a rebranding with new trains, this could be a popular route.
A version of Hitachi’s ubiquitous bi-mode Class 802 could be used.
But.
- They would need to be ordered and built.
- The third-rail gear, would need to be developed and tested.
- Passengers would be travelling for over two and a half hours with underfloor diesel engines.
An alternative could be a Class 68-hauled rake of Mark 5a coaches.
- These trains would be available after release from TransPennine Express.
- They would run in TransPennine Express formation.
- Length could be adjusted by adding or removing coaches, if required.
- The noise is all in the locomotive, which is isolated from the passengers.
At some point in the future, the route could be decarbonised by swapping the locomotive for a hydrogen-electric locomotive with the ability to handle third-rail electrification.
ScotRail
ScotRail have a similar problem to Great Western Railway with their short-formation InterCity125s.
- They have 52 Class 43 locomotives and 120 Mark 3 coaches, which is probably enough for 24 trains.
- Scotland has substantial amounts of electrification.
- I feel that a Class 68-hauled rake of Mark 5a coaches would be a more than adequate replacement.
- Class 93 locomotives could be used where routes are partially electrified.
- Scotland is not going to be short of green hydrogen.
When a suitable hydrogen-electric locomotive is available, these trains can be decarbonised.
CrossCountry
CrossCountry have a fleet consisting of the following trains.
- 5 – 2+7 InterCity125 trains
- 7 – two-car Class 170 trains
- 22 – three-car Class 170 trains
- 34 – four-car Class 220 trains
- 4 – four-car Class 221 trains
- 20 – five-car Class 221 trains
Note.
- The fleet is all diesel.
- I’ll ignore the Class 170 trains in this analysis.
- The Class 220 and 221 trains often work in pairs to provide the required capacity.
So how could these trains be decarbonised?
- The InterCity125s and the Class 220 and 221 trains could be replaced by a locomotive-hauled rake of Mark 5a coaches of an appropriate length.
- Motive power could be provided by an appropriate Class 68 or 93 locomotive.
When a suitable hydrogen-electric locomotive is available, these trains can be fully decarbonised.
Decarbonisation Of UK Main Line Services
It is generally assumed that the railways of the UK will need to fully decarbonise if the UK and the constituent nations are going to meet their decarbonisation targets.
I believe that my analysis shows that decarbonisation of main line passenger services can be achieved by the purchase of two types of trains.
- Five-car bi-mode Class 802 trains or similar.
- Locomotive-hauled rakes of Mark 5a coaches of an appropriate length.
Note.
- The Class 802 trains would be mainly to augment existing Hitachi fleets.
- Some Class 802 trains would be fitted with batteries instead of diesel generators to handle gaps in the electrification.
- The rakes of coaches would be powered by an appropriate locomotive.
- The lengths of the rakes of coaches would be adjusted to meet the demand of each service.
Initially, the following locomotives would be used.
- Class 68 locomotives would be used on unelectrified lines.
- Class 93 locomotives would be used on full or partially electrified lines.
When the hydrogen-electric locomotives become available, these would take over the routes, which couldn’t be decarbonised by full electrification or by using a Class 93 locomotive.
Northern Trains Plans Framework Contract For 450 Multiple-Units
The title of this post, is the same as that of this article on Railway Gazette.
This is the first paragraph.
Northern Trains has invited expressions of interest in a framework contract covering the supply of up to 450 multiple-units to replace ‘significant quantities of its ageing fleet’.
These are other details.
- Firm orders would be placed in phases.
- The initial order would be for ‘multi-mode’ multiple-units.
- Battery-electric or electric-only trains would be included in subsequent orders.
- Trains would have a minimum design life of 35 years from acceptance.
- The ability for the multi-mode units to be converted to electric or battery-electric power as part of an ‘in-life decarbonisation’ programme.
These four paragraphs outline the framework agreement between Northern Trains, the train manufacturer and the owners, who will finance the trains.
The framework agreement would run for eight years, with Northern able to order rolling stock in multiple phases.
Each phase would include a train manufacturing and supply agreement and a technical support and spares supply agreement.
The supplier would provide tools and spare parts, and there would be options for the supply of mock-ups and a cab simulator. Northern is to run a separate procurement for an owning party which would purchase each fleet and lease it to the operator.
The owner would be party to each manufacturing and supply agreement, and there may be different owning parties for each order phase.
This is a well-thought out proposal, that would be worth around a billion pounds to the train manufacturer.
It would probably be based around a family of trains like Alstom’s Aventra, CAF’s Civity or Stadler’s FLIRT.
For a series of orders of such a value, I think we will see some excellent proposals.
The deal will transform rail travel in the North.
I have some thoughts.
Which Trains Will Be Replaced?
Northern Trains fleet includes these ageing trains.
- Class 150/0 diesel trains – 6 x three-car – 18 cars
- Class 150/1 diesel trains – 46 x two-car – 92 cars
- Class 150/2 diesel trains – 26 x two-car – 52 cars
- Class 155 diesel trains – 7 x two-car – 14 cars
- Class 156 diesel trains – 65 x two-car – 130 cars
- Class 158/0 diesel trains – 45 x two-car – 90 cars
- Class 158/9 diesel trains – 8 x three-car – 24 cars
- Class 319 electric trains – 12 x four-car – 48 cars
- Class 323 electric trains – 34 x three-car – 102 cars
- Class 333 electric trains – 16 x four-car – 64 cars
- Class 769 bi-mode trains – 8 x four-car – 32 cars
Note.
- These total to 273 trains and 661 cars.
- If the 16 Class 170 trains, which are of three-cars, were also to be replaced. that would bring the total trains to be replaced to 289 trains and 709 cars.
I would expect the difference between 273-289 current trains and 450 trains in the article, is explained by new services and increased services on certain routes.
Which Trains Could Be Retained?
Northern Trains fleet includes these new trains.
- Class 195 diesel trains – 25 x two-cars – 50 cars
- Class 195 diesel trains – 33 x three-cars – 99 cars
- Class 331 electric trains – 31 x three-cars – 93 cars
- Class 331 electric trains – 12 x four-cars – 48 cars
Note.
- These trains were all built by CAF in the last five years.
- These total to 101 trains and 290 cars.
But if they have an expected life of 35 years, the diesels will have to be converted to zero-carbon trains.
Will The CAF Trains Be Retained?
Consider.
- If all the ageing trains and those not built by CAF were to be replaced then that would be 289 trains and 709 cars.
- If the nearly-new CAF trains were also to be replaced that would be 390 trains and 999 cars.
- Add in a few more trains for expanded services and you’re got the figure of 450 trains given in this article.
- If the CAF trains were to be replaced, then Northern Trains would have an homogenous fleet of new trains from one manufacturer, with all the advantages in operation and maintenance.
On the other hand, I haven’t read any bad criticism of these CAF trains, so I will assume that there is no pressing reason to replace them.
And of course Northern Trains could have an homogenous fleet of new CAF trains.
This is said in the article.
The supplier would provide tools and spare parts, and there would be options for the supply of mock-ups and a cab simulator.
As this is specifically mentioned, do Northern lack a simulator for driver training?
What About The Manchester Bee Network And Other Local Networks?
Will these networks want to take control of their local trains?
If there is an homogenous fleet of new trains from one manufacturer, then surely, it would be easier to give control of some routes to the local transport interests.
Training and driver rostering could be retained in what was left of Northern Trains.
Tram-Trains
Tram trains would be an added complication, but as the South Wales Metro is showing, tram-trains are an interesting way of expanding a network.
Key Mainline Testing Undertaken In Bi Modal Hydrogen Train Project
The title of this post, is the same as that of this article on Rail Technology Magazine.
This is a key paragraph.
In the test, lithium-titanate batteries and the hydrogen fuel cells have been retro-fitted to a CAF Civia Class 463 commuter electric unit train. This then has the ability to create a hybrid powertrain which can run on electrified lines alongside standard lines.
This paragraph describes some of the testing.
The new power system has been integrated into the existing vehicle’s traction system and the current tests on the mainline follow closed track testing and static testing at CAF’s plant in Zaragoza. The mainline testing has taken place across lines in Zaragoza, Madrid and Galicia but the crucial test run for the new unit was on the Zaragoza-Canfranc line where it ran in both electric mode on the electrified line before switching to hybrid mode, combining the fuel from hydrogen fuel cells and batteries where needed.
It sounds like this is a better specified hydrogen-powered train than Alstom’s iLint.
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.
Are These Two Stories Related?
These are two stories recently published in Railway Gazette.
Deutsche Bahn Sells Arriva Businesses To Private Equity Holding Company, which starts with this paragraph.
Deutsche Bahn has reached agreement to sell its Arriva local transport activities in Denmark, Poland and Serbia to München-based private equity holding company Mutares SE & Co KGaA.
That is fairly clear and is probably related with the German government’s desire for DB to concentrate on its core business.seren
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 also is fairly clear and would bring competition to services to and from South Wales.
It would also help in the financing of Grand Union Trains.
The article also says the following.
- RENFE seem to be expanding into partnerships to run services outside Spain.
- A parkway station at Felindre will be build to avoid the reverse at Swansea, that would save 20 mins.
- It will be a high quality service with new electro-diesel trains.
- Four trains will be needed.
- A 2025 start is envisaged.
Will this partnership with Grand Union Trains proceed with the development of Grand Union Trains’ London and Stirling service?
I have some thoughts and questions.
Will Deutsche Bahn Sell Other Arriva Businesses?
I think this is a reasonable question to ask, especially, as Deutsche Bahn owns two Open Access Operators in the UK; Chiltern Railways and Grand Central Trains.
- Both operators have a good reputation.
- Both operators need to decarbonise, either by updating their current stock or buying new trains.
- Both operators have solid niche markets, where they are often responsible for the stations.
- Both operators have expansion plans.
Would RENFE and Serena Industrial Partners be interested in taking over Arriva UK and developing the business?
The Talgo Factory At Longannet
I believe that there is reason to believe that one of Talgo’s reasons for a factory in Scotland, is that it could have been used to build Russian and dual-gauge trains for Eastern Europe. The trains would have been delivered by ferry from Rosyth.
There is also the not-small matter of the fleet for Rail Baltica, for which Talgo will surely be a bidder.
But Russia’s attack on Ukraine has scuppered that plan, or at least delayed it for a few years. But now, there could be a much larger market for trains in Eastern Europe and especially Ukraine.
If RENFE Acquire Open Access Operators In The UK, They Will Need New Trains
They will certainly need new trains for the South Wales operations, if they go ahead, but if they were to decarbonise Chiltern and Grand Central, the order could be substantial.
With one Spanish train factory in the UK and another a possibility, I would suspect any train order would go to a Spanish train-builder.
If the orders fell right, could we see Talgo’s factory at Longannet built after all?
UK’s First 100mph Battery-Diesel Hybrid Train Enters Passenger Service
The title of this post, is the same as that of this article on ITV.
These are the first three paragraphs.
The UK’s first 100mph battery-diesel hybrid train is entering passenger service to cut carbon emissions and boost air quality.
It was developed by adding a powerful battery to a 20-year-old diesel train to reduce fuel consumption and CO2 emissions by 25%, according to owner Porterbrook.
The firm added that the two-carriage train, named HybridFLEX, also provides a 75% decrease in noise and a 70% decrease in nitrogen oxide.
The battery-diesel hybrid transmission is from MTU, who are a Rolls-Royce company and they go further with this press release which is entitled World Premiere: MTU Hybrid PowerPack From Rolls-Royce Enters Passenger Service.
This is the first paragraph.
Rolls-Royce, Porterbrook and Chiltern Railways are making rail history together with a climate-friendly world premiere: A hybrid diesel-battery-electric train that reduces CO2 emissions by up to 25% entered passenger service in the UK today for the first time. The so-called HybridFLEX train is powered by two mtu Hybrid PowerPacks and is operated by Chiltern Railways on the route between London Marylebone and Aylesbury. Together with the leasing company Porterbrook and Chiltern Railways, Rolls-Royce has converted a Class 168 DMU into the HybridFLEX train. The partners are proving that existing rail vehicles can be used in a climate-friendly way without the need to install complex and expensive new infrastructure. It is the world’s first regular passenger operation with mtu Hybrid PowerPacks, of which 13 have already been ordered.
This is significant for the railways of the UK.
The train that has been converted is a Class 168 train, which itself had been converted from a Class 170 train, when it transferred to Chiltern Railways in 2016.
I think this means that all Bombardier Turbostars in Classes 168, 170, 171 and 172 can probably be fitted with MTU Hybrid PowerPacks.
That is the following numbers of trains and cars.
- Class 168 – 28 trains – 86 cars
- Class 170 – 139 trains – 372 cars
- Class 171 – 20 trains – 56 cars
- Class 172 – 39 trains – 93 cars
Note.
- This totals to 226 trains and 607 cars.
- As each car has an engine, this will be an order of 607 PowerPacks, if all trains were to be converted.
This could certainly help to meet the Government’s aim of getting rid of all diesel only trains by 2040.
Can The CAF Civities Be Converted?
There are three Classes of CAF Civity diesel multiple units; 195, 196 and 197, all of which have Rolls-Royce MTU engines.
Could these be converted to hybrid operation by the swapping of the current diesel engines for MTU Hybrid PowerPacks?
I would suspect they could, as the CAF Civity trains might have been designed after MTU disclosed plans of the MTU Hybrid PowerPack to train builders prior to its announcement in September 2018.
Conclusion
MTU Hybrid PowerPacks could go a long way to eliminating diesel-only trains on UK railways. They could even run the diesels on Hydrotreated Vegetable Oil (HVO) to lower their carbon-footprint further.
Aberdeen’s Hydrogen Buses Taken Off The Road Due To Technical Issue
The title of this post, is the same as that of this article on the BBC.
This is the introductory paragraph.
Aberdeen’s fleet of hydrogen buses has been taken off the road due to a “technical issue”.
The technical issue appears not to be hydrogen-related, but with a mounting bracket.
Strange coming after CAF had bracket trouble with their trams and Hitachi had a similar problem with their trains.
Wrightbus, CAF and Hitachi haven’t been using the save dodgy Chinese supplier called El Cheapo Brackets have they?
