Battery EMUs For Merseyrail

The title of this post is the same as an article in the August 2017 Edition of Modern Railways.

This is the first paragraph.

Two of the new EMUs Stadler will build for the Merseyrail network will be fitted with batteries.

This is also said.

The initial benefits of the trial will be the energy recycling properties of the batteries, but with a larger battery the option could be to run the units away from the electrified Merseyrail network using battery power.

Other reports suggest that battery power could move the trains in depots.

Another report in the same edition of Modern Railways is entitled Class 769s For Wales.

It discusses the use of Class 769 trains on the Borderlands Line.

This is said.

Would safety regulations permit Class 769s, or other third-rail EMUs retrofitted with diesel engines, to operate the Wrexhm-Bidston Line and continue in the Mersey tunnels to Liverpool? No definite answer was available as Modern Railways went to press. Each bi-mode unit would displace pnly one two-car Class 150/2 unit from the line, but studies have predicted large growth in passenger numbers if the change of trains at Bidston were eliminated.

It is an interesting concept.

  • Porterbrook have already talked about converting Class 455 trains into bi-modes.
  • These third-rail units don’t have pantographs to snag in the tunnels.
  • They have been refurbished to a high standard in recent years.
  • The fuel safety problem in the tunnel, is something for which Formula One engineers may have a ready-made solution.

I’m sure if it does happen, Scouse humour will go into overdrive, about London cast-offs and old trains. But Class 455 bi-mode trains would have the last laugh.


It is encouraging to see in these two articles signs of radical but in my view totally sound thinking.
