Retrofitted Hydrogen Fuel Cell EMU Concept Presented

The title of this post is the same as that of this article on Global Rail News, that was published in April 2014.

This is the first two paragraphs.

The possibility of retro-fitting diesel multiple units (DMUs) to run on hydrogen fuel cell technology has been put to the test as part of an RSSB and Network Rail-funded innovation research programme.

Fuel Cell Systems, which has worked alongside the University of Birmingham and Hitachi Rail Europe, says the six-month study has demonstrated the feasibility of installing hydrogen fuel cell technology on DMUs as an alternative to electrification.

It strikes me that some serious people are involved in this project.

The report on the project was published in June 2016 and it is stored here on the University pf Birmingham web site.

Network Rail’s Independently Powered Electric Multiple Unit (IPEMU) Trial Report

The report of the BEMU trial using a Class 379 train is freely available on the Internet, after a simple registration and download.

It is a very professional document, that goes a lot further than describe how the trial was carried out.

Other information includes.

  • Battery power can aid the introduction of power sources such as hydrogen.
  • Objectives included a target range of 50 km and speed of 60-100 mph.
  • The list of those contributing to the project were impressive.
  • Three different types of battery were comprehensively tested.
  • The batteries were able to handle the regenerative braking.
  • Testing included runs at up to 100 mph and an extreme range test.
  • It is suggested that battery power could enhance safety.
  • It is suggested that electrification could be simplified, if trains had batteries.

In addition, Bombardier have developed software to analyse routes to see if they are suitable for battery operation.

As someone, who has spent most of my working life looking at the mathematics of systems, I suspect that lots of useful ideas have been indicated by Bombardier’s modelling.

I suspect that the bi-mode Aventra I discussed in Bombardier Bi-Mode Aventra To Feature Battery Power, is one train that has been designed extensively by computer simulation.

Aircraft have been designed that way for decades.

A Very Smart Class 319 Train

On my trip to Bricket Wood station yesterday, I travelled from Watford Junction station in a very smart Class 319 train.

These pictures show the train.

It certainly shows how Mark 3-based stock has the ability to scrub up well!

West Midlands Trains have nine of these Class 319 trains, which are mainly used for peak hour services on the West Coast Main Line.

One gets used on the Abbey Line.

The current arrangement probably works reasonably well from the train operators point of view.

However, passengers probably need a regular half-hourly service, which would need two trains and a passing loop at Bricket Wood station.

These trains are going to be replaced with new five-car Class 730 trains in 2020-21.

Will these new trains be used on the Abbey Line?

If the passing loop is installed at Bricket Wood, then two trains might be able to provide a half-hourly service. Although, having seen Bricket Wood station yesterday, a passing loop with electrification and a second platform would be a more expensive .option.

I discuss the various options in Could Modern Technology And Developments Improve the Abbey Line?.
