Stadler Receives First Flirt Akku Battery Train Order

The title of this post, is the same as that of this article in Railway Gazette International.

This is said.

Schleswig-Holstein transport authority NAH.SH has selected Stadler to supply 55 Flirt Akku battery multiple-units to operate regional services and provide 30 years of maintenance.

Announcing its selection as preferred bidder on June 19, Stadler said that it will reveal more details when the contract is signed, which is expected after the 10-day standstill period. NAH.SH called tenders for zero-emission trains to run on non-electrified lines but did not specify the technology to be used.

NAH.SH becomes the launch customer for the Flirt Akku, which was officially unveiled last year at the Stadler Pankow factory in Berlin.

Information on the order is a bit short, but that doesn’t stop me speculating.

Do The Flirt Akku Trains Have A Power-Pack Like Greater Anglia’s Class 755 Trains?

Certainly, the Stadler Flirts for the South Wales Metro, do have both a power-pack and a battery, as Stadler use the same image for both trains and the trains have batteries.

These pictures show some of Greater Anglia’s Class 755 trains in the sidings at Crown Point Depot.

Note, these are four-car Class 755 trains with a power-pack in the middle.

In Importance Of Battery Range: Stadler’s FLIRT BMU For Greater Anglia, I referenced an article, that said that Greater Anglia’s network is too long for battery trains. But the article seemed to suggest, that Greater Anglia could go battery in the future.

Until, I get more details on the Flirt Akku, I will assume that they use a power-pack containing batteries instead of diesel engines.

As in South Wales, there could also be a mix of diesel engines and batteries in the power-pack of a Flirt Akku.

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.

Conclusion

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.
