Rolls-Royce And Porterbrook Launch First Hybrid Rail Project In The UK With MTU Hybrid PowerPacks

The title of this post is the same as that on this Press Release from Porterbrook.

Porterbrook, Eversholt and the other train leasing companies have a problem, that can be turned into an opportunity to make money in a way, few will find unacceptable.

There are several fleets of trains in the UK, that are reasonably new and have plenty of life left in their basic structure, running gear and traction equipment.

But compared to modern rolling stock, they are like a twenty-year-old BMW, Jaguar or Mercedes. Good runners and comfortable, but not up to the standards, passengers, rail operators, rail staff and environmentalists expect.

So the train leasing companies are looking for ways to update their fleets, so that they can continue to earn money and satisfy everybody’s needs and aspirations.

Class 769 Train

Porterbrook started this innovation by taking redundant Class 319 trains and converting them into Class 769 trains, so they could be used on lines without electrification.

The picture shows one of Northern’s Class 319 trains.

Thirty-five of these trains have been ordered. So far, due to design and testing issues none have been delivered. Hopefully, as testing has now started, some will be in traffic before the end of the year.

This project could create upwards of fifty much-needed four-car bi-mode trains for running on partially-electrified routes.

Class 321 Hydrogen Train

Eversholt have also teamed up with Alstom to create a hydrogen-powered version of their Class 321 train.

This project could create around a hundred four-car 100 mph, zero-emission electric trains, for running on routes with no or only partial electrification.electrification.

The Four-Car High Speed Train

Everybody loves High Speed Trains and Scotrail and Great Western Railway  are taking a number of them and creating four-car quality trains to increase their rolling stock.

The picture shows a High Speed Train under test in Glasgow Queen Street station.

They are already running in Cornwall and they should be running in Scotland before the end of the year.

Updating The Class 170 Trains

The Press Release announces Porterbrook’s latest project and gives this picture.

There are 122 Class 170 trains on the UK rail network, which were built around twenty years ago. There are also nearly a hundred other Class 168, 171 and 172 trains with a similar design.

They are 100 mph trains, that are diesel-powered and some are used on long distances.

As a passenger, they are not a bad train, but being diesel, they are not that environmentally friendly.

The Class 172 trains, which are currently running on the Gospel Oak to Barking Line, would surely be a much better train with a smoother electric transmission, that had regenerative braking. Although, as they have a mechanical transmission, rather than the hydraulic of the other Turbostars, this might not be possible.

On the other hand, West Midlands Trains will soon have a fleet of thirty-five Class 172 trains of various sub-types, so fuel savings could be significant.

This is from the Press Release.

Rolls-Royce and Porterbrook, the UK’s largest owner of passenger rolling stock, have agreed the delivery of MTU Hybrid PowerPacks that can convert Class 168 and Class 170 ‘Turbostar’ DMUs from diesel-only to hybrid-electric operation. Hybrid technology allows for the cleaner and quieter operation of trains in stations and through urban areas.

As I understand it, the current hydraulic traction system will be replaced by an electric one with a battery, that will enable.

  • Regenerative braking using a battery.
  • Battery electric power in urban areas, stations and depots.
  • Lower noise levels
  • Lower maintenance costs.

This should also reduce diesel fuel consumption and carbon emissions.

Conclusion

The good Class 170 trains, are being improved and should give another twenty years of service.

How many other projects like these will surface in the next few years?

  1. […] This involves using an MTU Hybrid PowerPack, from the same family as those, that will be used in the UK to upgrade the Class 170 trains. I talked about the latter project in Rolls-Royce And Porterbrook Launch First Hybrid Rail Project In The UK With MTU Hybrid PowerPacks. […]
