UK Rolling Stock Strategy: Diesel, Bi-mode and Fuel Cell-Powered Trains

The title of this post is the same as that on an article in Global Rail News.

I will not repeat myself here, but I laid down my thoughts in The Intelligent Multi-Mode Train And Affordable Electrification.

In that post, I said that an Intelligent Multi-Mode Train would have these characteristics.

  • Electric drive with regenerative braking.
  • Diesel or hydrogen power-pack.
  • Onboard energy storage to handle the energy generated by braking.
  • 25 KVAC and/or 750 VDC operation.
  • Automatic pantograph and third-rail shoe deployment.
  • Automatic power source selection.
  • The train would be designed for low energy use.
  • Driver assistance system, so the train was driven safely, economically and to the timetable.

Note the amount of automation to ease the workload for the driver and run the train efficiently.

After discussing affordable electrification, I came to the following conclusion.

There are a very large number of techniques that can enable a multi-mode train to roam freely over large parts of the UK.

It is also a team effort, with every design element of the train, track, signalling and stations contributing to an efficient low-energy train, that is not too heavy.
