What Will Be The Power Unit In LNER’s New CAF Tri-Mode Trains?
There is a short article in the January 2024 Edition of Modern Railways, that is entitled New LNER Fleet To Have Joint Line Capability.
This is said about the diesel engines in the new CAF tri-mode trains.
CAF will supply 10×10-car trains with overhead electric, battery and diesel capability, financed by Porterbrook. The inclusion of diesel engines as part of the winning bid, rather than a straightforward battery-electric unit, has surprised some observers, but LNER’s specification was that the fleet should have sufficient self-powered capability to cover the length of the joint line, which is approximately 90 miles. This is currently to be considered to be beyond the scope of battery-power alone, although as the technology evolves diesel engines could be replaced by batteries. The configuration of diesel engines and batteries within the sets has yet to be decided.
As the paragraph says that the diesel engines can be replaced by batteries and the trains are from CAF’s modular Civity family, it sounds like CAF are using a modular power system.
The CAF Class 195, 196 and 197 diesel multiple units, that are used in the UK, use mtu Railcar Power Packs, which are shown on this web page.
mtu are a Rolls-Royce subsidiary.
mtu also make a Hybrid Power Pack, which is shown on this web page.
This is the sub-title on the web page.
Individual hybrid drive with a modular design
Underneath is this sub-heading.
It takes revolutionary thinking to develop a smart rail drive system like the Hybrid PowerPack. Find out what makes mtu different, and why our Hybrid PowerPack brings added value to operators while benefiting passengers and the environment alike.
These paragraphs describe the mtu Hybrid PowerPack.
The Hybrid PowerPack was developed from the successful mtu underfloor drives: Tried and tested mtu PowerPacks were modified and equipped with additional components and functionalities in order to integrate hybrid technology. The mtu hybrid concept consists of a modular kit with a variety of drive elements. It satisfies all existing railway standards and can be arranged according to customer specifications.
Thanks to its compact design and the use of power-dense electrical machines, the Hybrid PowerPack can be easily integrated in the existing installation space under the floor, both in new rail vehicles or for repowering. mtu EnergyPacks – the energy storage – can be positioned at various places in the vehicle: on the roof or underfloor. The modular design creates great flexibility for operators who are planning new diesel hybrid vehicles or want to convert existing vehicles.
Based on specifications for the hybrid train and the profile of the planned routes, mtu can simulate the lifecycle costs (capital, maintenance and operating costs) of specific projects. This means that a variety of drive options can be defined even before the design stage. Together with you, we then determine an optimal concept based on your needs.
Note.
- mtu Hybrid PowerPacks can be used in new rail vehicles or for repowering.
- It looks to me, that the total of 161 of Class 195, 196 and 197 trains, that will soon be all in service in the UK may well have been designed to be converted to hybrid power using mtu Hybrid PowerPacks.
- In Would You Buy A Battery Energy Storage System From Rolls-Royce?, I talk about how mtu EnergyPacks are also used for battery storage.
- In fact, mtu EnergyPacks could be the secret ingredient to both systems.
This looks like a typical Rolls-Royce product, that pushes the design to the full.
I will be very surprised if LNER’s new CAF tri-mode trains are not powered by mtu Hybrid PowerPacks.
I have a few thoughts.
CAF Are Going For A Proven Solution
CAF are going for a proven power solution, that they will also need for 161 trains in the UK.
Integration of systems like these can be difficult but CAF are using another company to combine diesel, electric and battery power in an efficient way.
I also feel that mtu Hybrid PowerPacks have a big future and Rolls Royce mtu will do what it takes to make sure they dominate the market.
Decarbonising The Trains
I suspect given Rolls-Royce’s philosophy, that the diesel engines will run on sustainable fuels from delivery.
But as the extract from the Modern Railways article says, the space used by diesel engines can be used for batteries.
Follow The Money
Consider.
- Porterbrook and Rolls-Royce are both based in Derby.
- Porterbrook are a rolling stock leasing company, who own a lot of rolling stock, that could be converted to hybrid trains, using mtu Hybrid PowerPacks.
- Porterbrook are financing LNER’s new CAF tri-mode trains.
I wouldn’t be surprised if Porterbrook and Rolls-Royce have done a lot of due diligence on these trains.
Other Train Operators Will Follow
LNER’s new CAF tri-mode trains may be a bespoke design for LNER, but other train operators will need a similar train.
- CrossCountry need a replacement low-carbon fleet.
- ScotRail need a replacement fleet for their Inter7City services.
- Great Western Railway need a replacement fleet for their GWR Castles.
- Grand Central need a replacement low-carbon fleet.
- TransPennine Express need new trains.
- Open Access Operator Grand Union Trains will need trains.
I think CAF are gong to be busy.
Conclusion
The more I read about Rolls-Royce and its engineering, the more I’m impressed.
Do Rolls-Royce mtu Have A Plan To Decarbonise Their Diesel Engines For Rail Applications?
Data Sheets For Rolls-Royce mtu Diesel Engines For Trains
These are data sheets for various Rolls-Royce mtu diesel engines that can be used in rail applications.
Rolls-Royce Releases mtu Rail Engines For Sustainable Fuels
The title of this section, is the same as that of this press release from Rolls-Royce.
These four bullet points, act as sub-headings.
- mtu Series 1300, 1500 and 1800 engines already released; Series 1600 and 4000 to follow shortly
- Up to 90% CO2 savings by operating existing engines with Hydrotreated Vegetable Oil (HVO/renewable diesel)
- Locally emission-free operation possible in combination with mtu Hybrid PowerPack
- Field tests with DB Cargo and RDC Autozug Sylt
This is the first paragraph.
Rolls-Royce is taking a significant step towards even more climate-friendly rail transport with the release of mtu rail engines for use with sustainable fuels. With synthetic diesel fuels of the EN15940 standard, CO2 emissions can be reduced by up to 100 percent compared to fossil diesel. Hydrotreated Vegetable Oil (HVO or renewable diesel), which is already commercially available today, reduces CO2 emissions by up to 90 percent. If the fuels are produced with the help of renewable energy and green hydrogen – through what is termed a Power-to-X process – existing rail vehicles can be operated in a completely CO2-neutral manner. The mtu Series 1800 engines which are used in mtu PowerPacks, as well as Series 1300 and 1500 for locomotives and multi-purpose vehicles, are already approved for use with synthetic fuels such as HVO. Series 1600 and versions of Series 4000 engines will follow in the near future. The release of engines for climate-friendly fuels requires a series of tests and trials and Rolls-Royce has found strong partners for this activity. DB Cargo and RDC Autozug Sylt have already tested or are currently testing mtu Series 4000 engines with HVO in their locomotives.
How Does That Fit With The UK’s Population Of Rolls-Royce mtu Diesel Engines?
These classes of train have Rolls-Royce mtu engines.
- Class 43 power cars – 6V 4000 R41R
- Class 168 train – 6R 183 TD 13H
- Class 170 train – 6R 183 TD 13H
- Class 172 train – 12V 1800 R83
- Class 195 train – 12V 1800 R85L
- Class 196 train – 12V 1600 R85L
- Class 197 train – 12V 1600 R85L
- Class 800 train – 12V 1600 R80L
- Class 801 train – 12V 1600 R80L
- Class 802 train – 12V 1600 R80L
- Class 805 train – 12V 1600 R80L
- Class 810 train – 12V 1600 R80L
Note.
- Class 168 and 170 trains seem to be powered by older model Rolls Royce mtu engines.
- Class 180, 220,221 and 222 trains are powered by Cummins engines.
- I can’t find what engines power Class 805 and 810 trains, but it is reasonable to assume they have the same engines as the other Hitachi trains.
- As CAF are building LNER’s new tri-mode trains, I suspect these trains will also have Rolls Royce mtu engines.
It would appear that all the Rolls-Royce mtu rolling stock in the UK, with the possible exception of the Class 168 and 170 trains will be able to run on sustainable fuels.
Rolls Royce mtu And Hydrogen
This press release from Rolls-Royce is entitled Rolls-Royce Successfully Tests mtu Engines With Pure Hydrogen.
This is the first paragraph.
Rolls-Royce today announces that it has conducted successful tests of a 12-cylinder gas variant of the mtu Series 4000 L64 engine running on 100% hydrogen fuel. The tests, carried out by the Power Systems business unit, showed very good characteristics in terms of efficiency, performance, emissions and combustion. These tests mark another important step towards the commercial introduction of hydrogen solutions to meet the demand of customers for more sustainable energy.
Engines of mtu’s 4000 family are used in Class 43 power cars, so surely these developments could lead to hydrogen-powered freight locomotives.
The picture shows a Class 43 power car at Glasgow Queen Street station.
Could Rolls-Royce mtu hydrogen power keep these iconic trains running for a few more years?
In ‘Spirit of Innovation’ Stakes Claim To Be The World’s Fastest All-Electric Vehicle, I look at Rolls-Royce’s Spirit of Innovation, which set the record for an electric vehicle at 555.9 km/hour.
As the InterCity125 already holds the record for the fastest diesel train, perhaps Rolls-Royce will attempt to set a record for the fastest hydrogen-powered train?
Decarbarbonising The CAF Class 195, 196 And 197 Trains
If Rolls-Royce mtu develop a hydrogen version of the 1800 diesel engine, then this could be used to fully decarbonise the CAF trains.
The operators may consider it’s not worth it and continue with using sustainable fuels.
But the possibility is surely there.
There must also be the possibility of developing a fuel cell replacement for the 1800 diesel, that can be slotted into the train.
Decarbarbonising The Hitachi Class 80x Trains
Hitachi are developing battery packs and the data sheet can be downloaded from this page on the Hitachi web site.
Decarbarbonising The CAF Tri-Mode Trains
I feel that as CAF usually use Rolls-Royce mtu engines, I suspect these trains will be designed, so they can be converted to hydrogen.
Conclusion
Rolls-Royce mtu appear to be on a path to decarbonise all their diesel engines.
Carew Castle Express Unveiled In Carmarthen
The title of this post, is the same as that of this article on Rail UK.
These are the first two paragraphs.
The ‘Carew Castle Express’ has been unveiled to mark the introduction of brand-new Transport for Wales (TfW) trains between Swansea and Carmarthen.
Named as part of TfW’s Magnificent Train Journey competition, the name ‘Carew Castle Express’ was chosen by year 5 pupil Rhys Protheroe from Johnstown Primary School in Carmarthen.
But perhaps, this extract is the most significant statement in the article.
Soon every service west of Carmarthen will be on one of the brand-new trains.
Alexia Course, chief commercial officer for TfW, said: “We’re excited to be running our brand-new trains in West Wales and we’re adding more to our network every few weeks.
CAF and TfW don’t seem to be hanging about in getting these new trains into service.
But then, I suspect some of the trains they replace, will be going to the scrapyard in Newport.
How Will These Trains Be Decarbonised?
My one worry is that these Class 197 trains and the similar Class 195 trains at Northern and the Class 196 trains at West Midlands Trains are diesel powered.
Nothing has been said about how these 141 trains will be decarbonised.
But all three fleets have the same Rolls-Royce mtu 6H 1800 R85L engines, so at least one solution will fit all!
A Thought About LNER’s New Trains
These trains appear to have been delivered quickly.
Did this influence the decision of LNER to buy CAF trains for their fleet expansion?
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.
