Prototype Revolution Very Light Rail Vehicle Ready For Testing

The title of this post, is the same as that of this article on Rail Business UK.

It is very much a complete article, which gives full information on the current status of the Revolution VLR very light rail prototype railcar.

  • The railcar is an eighteen metre long bi-directional vehicle.
  • It has capacity for 56 seated passengers and 40 standees. This is more than a double-deck bus load.
  • It has a Cummins diesel-electric power-train.
  • Maximum speed is 65 mph.
  • There is regenerative braking to a battery, which can be used for traction in built-up areas.

I must admit that I am surprised that Revolution VLR is not fully zero-carbon, but as this is a prototype, that is probably a sensible move, as it will be able to test the concept and show the railcar to potential customers.

However, as Cummins are a member of the consortium and they are now embracing hydrogen as an alternative fuel, a zero-carbon hydrogen power-train may be under development, that would be suitable for the Revolution VLR.

When the Revolution VLR consortium was in its early stages I wrote Very Light Rail Research On Track, based on a Railway Gazette article with the same title.

That earlier article did talk about a problem.

However, the drawback of a lightweight vehicle is that its lower crashworthiness could make it unsuitable for mixed traffic lines.

But the consortium felt that the limitation could be overcome by better traffic management and digital signalling.

Mixed traffic running was also flagged up as a problem by the tram-trains running in Sheffield, but touch wood, they seem to be working well!

Hopefully extensive testing of this prototype will identify any limitations of the concept.
