Battery Power To Extend Dublin Commuter Services As Alstom Wins DART Fleet Renewal

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

This is the first paragraph.

Alstom was formally confirmed as supplier of up to 750 suburban multiple-unit cars for Iarnród Éireann as part of its DART+ Programme on December 13, having been named preferred bidder in June.

Interesting part of the fleet renewal is that the trains will be extended from Malahide to Drogheda by using battery power.

  • The distance is probably around 41 km. or 25 miles.
  • Trains will have a range of 80 km on battery power.
  • Trains will take twenty minutes to recharge.

It certainly looks to be a good use of battery electric multiple units or BEMUs.

According to the DART+ entry in Wikipedia, the DART will be extended to Drogheda, Maynooth, Hazelhatch, M3 Parkway and Docklands, which could require another 40 km of electrification.

So it looks like the the BEMUs will earn the extra cost of their batteries.

  1. Very smart buy and the UK could easily absorb 750 BEMU vehicles now that could be used on many routes to get the benefits of reduced emissions now and not wait for electrification or actually not even have to bother with it.

  2. I rode a successful battery-electric train in Essex in 2015, As you say there are several routes, where BEMUs would work. It seems to me, that it isn’t the politicians judging by their statements.

    Perhaps there is a senior civil servant in the Treasury, who doesn’t believe battery-electric trains work. Perhaps he needs a few hours with Adrian Shooter and Steve Rotherham.
