- Five-car – 176
- Seven-car – 4

That is a total of 1254 trains that need to be decarbonised by either replacement or modification.
- Some trains are effectively double-counted, as both the current trains and their replacements are included.
- Some trains are planned to be replaced by electric trains.
- Some trains will be passed on.
But there are still a lot of trains to be decarbonised.
I will now look at each group in detail.
BR Second Generation Trains
- Class 150 – 129 x two-car and 6 x three-car.
- Class 153 – 36 x one-car.
- Class 155 – 7 x two-car.
- Class 156 – 109 x two-car.
- Class 158 – 155 x two-car and 15 x three-car.
- Class 159 – 29 x three-car.
- Class 165 – 59 x two-car and 16 x three-car.
- Class 166 – 21 x three-car.
Note.
- The trains have mostly Cummins engines, with some Perkins and a spattering of Rolls-Royce.
- Class 150,153, 155 and 156 trains are 75 mph trains and most of the others are capable of 90 mph.
- Condition of the interiors is variable, with some being excellent and others being terrible.
- There are 36 x one-car, 459 x two-car and 59 x three-car.
- There appears to be no plan to decarbonise these trains.
- Some will be replaced by new CAF diesel trains or new electric trains.
The best use of some of the better trains in this group would be to fill-in until zero-carbon trains are available.
Turbostar Trains
These trains are all Turbostars or their predecessor.
- Class 168 – 9 x two-car, 9 x three-car and 13 x four-car.
- Class 170 – 34 x two-car and 71 x three-car.
- Class 171 – 17 x three-car.
- Class 172 – 24 x two-car and 15 x three-car.
Note.
- The trains all have Rolls-Royce mtu engines.
- They are capable of 100 mph.
- Condition of the interiors is generally good.
- There are 67 x two-car, 112 x three-car and 13 x four-car.
- Rolls-Royce mtu engines may be able to run on sustainable fuel like Hydrotreated Vegetable Oil (HVO).
- 168329 has been converted into a diesel-hybrid, by Rolls-Royce mtu.
I feel that one way or another, the trains in this group should be capable of converting to net-zero operation.
Alstom Coradia, Bombardier Voyager and Siemens Desiro Trains
I am putting these trains together, as they are all 100-125 mph long-distance trains, that are not that old.
- Class 175 – 9 x two-car and 15 x three-car.
- Class 180 – 1 x four-car and 12 x five-car.
- Class 185 – 51 x three-car.
- Class 220 – 34 x four-car
- Class 221 – 24 x four-car and 18 x five-cars
- Class 222 – 23 x five-car and 4 x seven-car.
Note.
- The trains all have Cummins engines.
- They are capable of 100 mph or 125 mph.
- Condition of the interiors is generally good.
- There are 9 x two-car, 66 x three-car, 59 x four-car, 53 five-car and 4 x seven-car.
- Cummins engines may be able to run on sustainable fuel like Hydrotreated Vegetable Oil (HVO).
- In Grand Central DMU To Be Used For Dual-Fuel Trial, I described innovative fuel trails in a Class 180 train.
- I suspect Cummins will be taking an interest.
In Cummins And Leclanché S.A. To Collaborate On Lower-Emissions Solutions For Use In Marine And Rail Applications, I asked this question.
How many of these trains could be converted to hybrid operation, if Cummins and Leclanché were to create their version of the mtu Hybrid PowerPack?
I feel that one way or another, the trains in this group should be capable of converting to net-zero operation.
CAF Civity Trains
These three trains have all been recently introduced
- Class 195 – 25 x two-car and 33 x three-car.
- Class 196 – 12 x two-car and 14 x four-car.
- Class 197 – 51 x two-car and 26 x three-car.
Note.
- The trains all have Rolls-Royce mtu engines.
- They are capable of 100 mph.
- Condition of the interiors is probably as-new!
- There are 88 x two-car, 59 x three-car and 14 x four-car.
- All these trains were ordered between 2016 and 2018.
- Rolls-Royce mtu engines may be able to run on sustainable fuel like Hydrotreated Vegetable Oil (HVO).
I don’t believe that as these trains were only ordered a few years ago, that the trains were bought with the knowledge of a route which would convert these trains to net-zero operation.
I suspect the most likely route to net-zero operation, would involve the following.
- Replacing the Rolls-Royce mtu engines with mtu Hybrid PowerPacks.
- Running the trains on sustainable fuel.
The work needed would probably be the same for all trains.
Stadler FLIRT Bi-Mode Trains
- Class 231 – 11 x four-car.
- Class 755 – 14 x three-car and 24 x four-car.
- Class 756 – 7 x three-car and 17 x four-car.
Note.
- The trains all have Rolls-Royce mtu engines.
- They are capable of between 75 and 100 mph.
- Condition of the interiors is probably as-new!
- There are 21 x three-car and 52 x four-car.
- All these trains were ordered between 2016 and 2018.
- As with other recently ordered trains, I am fairly sure that the Deutz engines will be able to run on sustainable fuel like Hydrotreated Vegetable Oil (HVO).
Stadler have designed these trains, so that diesel engines can be replaced by battery packs.
I suspect the most likely route to net-zero operation, would involve the following.
- Replacing all or some the Deutz engines with battery packs.
- Running the trains on sustainable fuel.
The work needed would probably be the same for all trains.
Hitachi AT-300 Trains
Only the bi-mode trains are lists.
- Class 800 – 31 x five-car and 49 x nine-car.
- Class 802 – 46 x five-car and 14 x nine-car.
- Class 805 – 13 x five-car.
- Class 810 – 33 x five-car.
Note.
- The trains all have Rolls-Royce mtu engines.
- They are capable of 125 mph.
- Condition of the interiors is probably as-new!
- There are 123 x three-car and 63 x nine-car.
- Most were built after 2016.
- Rolls-Royce mtu engines may be able to run on sustainable fuel like Hydrotreated Vegetable Oil (HVO).
- Hitachi are developing battery packs for these trains.
I suspect the most likely route to net-zero operation, would involve the following.
- Replacing all or some the Rolls-Royce mtu engines with battery packs.
- Running the trains on sustainable fuel.
The work needed would probably be the same or similar for all trains.
You say that the 2nd generation dmus have mostly Cummins engines, with some Perkins and a spattering of Rolls-Royce. Its all a bit convoluted but Perkins engines were in fact derived from Rolls-Royce units, Perkins having taken over the Rolls-Royce Sentinel Works, then a Vickers company, in Shrewsbury. The few Rolls-Royce designated engines were tested in the Pacer and Class 150 prototype. The Perkins engine found in Classes 158, 165 and 166 was a development of the R-R C Series.
Putting to one side the question of the control electrics, to replicate the Rolls-Royce mtu HydroFLEX, Cummins engines and Leclanché batteries alone would be inadequate to create their version of a Parallel Hybrid Power Pack. You will still require some form of transmission with an incorporated electric motor/generator; this makes up a significant element of the package. Although I don’t think they’d find it commercially attractive the best candidate would probably come out of the Eaton Cummins JV for automated transmissions, something Eaton started developing nearly 20 years ago with their Fuller truck gearboxes.
