Importance Of Battery Range: Stadler’s FLIRT BMU For Greater Anglia

The title of this post is the same as a sub-section of this article on Railway News, which is entitled Stadler Presents New FLIRT Akku For The First Time.

This is said.

By contrast, Stadler recently unveiled its bi-mode (electric-diesel) FLIRT for Greater Anglia (U.K.) at InnoTrans 2018. When asked why Greater Anglia went for a diesel-electric option rather than a battery-electric option to bridge the non-electrified gaps in the network, Railway-News was told that the non-electrified distances in the U.K. are currently too great for battery-operated trains to cope with. As battery technology improves, this will hopefully change, making diesel and the need for electrification obsolete

Does this infer the following?

  1. Greater Anglia would have preferred to use battery-electric trains.
  2. It is possible to swap the diesel engines in the power-pack for battery modules.
  3. It could be possible to swap a diesel generator for a hydrogen fuel cell.

Option three might be difficult, as you need somewhere to put the hydrogen tank within the limited UK loading gauge.


I think it is highly likely that as battery technology improves and Stadler are able to package it better for the Class 755 trains, that Greater Anglia will change some of their Class 755 trains to battery-electric operation.

  2. a German article I found claims a range of up to 150km, which is a lot. It may well be that the GB loading gauge limits that – until batteries reduce in size some more.

    • I tried to post the German link, but your site refuses to process it – does it perhaps treat German urls as spam??

    • I was told by the Bombardier engineer monitoring the Class 379 BEMU train on a laptop, that the train had a range of 50 km. Not bad for a demo. I believe that this is consistent with 150 km for a well-designed battery train.
