I don't think I buy BEV trains to be honest. I'm struggling to think of a proper reason why they might be better compared to normal electric trains.

But the linked article is pretty light on info, so I'll reserve judgement till more info comes to light.

The economics work out where they’re pretty low-frequency (I think less than two an hour per direction is the usual figure).

They’re also useful as a transition technology. The DART+ project in Ireland will use them for one line which will have the frequency for electrification (8 trains per direction per hour) and is already partially electrified, but is going to take a while to fully electrify (due to low bridges etc); once it’s electrified they’ll then likely be used in low-frequency regional routes.

(The realised project will use 750 uniform cars, about 200 of which will have batteries.)

They are good for infrequently used track and places where overhead wires would be in the way, like that very Tesla employee shuttle on it's own track and container ports.

It's not the best way to go for mainline track and not suitable for long distance high speed trains.
