Train engines work hard to get the train up to crusing speed (60 mph for
these trains). That takes a few minutes. The rest of the time they're
producing very little power. The engines will cut out automatically when
power isn't needed, just as road vehicles do.

Road vehicles can get away with that because the transmission keeps the
engine spinning so no restart is needed - the ECU simply starts injecting
fuel again. That won't work with a generator engine.

Mostly the engines stop in road vehicles when the vehicle is
stationary, so the starter motor is needed. With the generator
modules, I wonder if they can use the generator as the starter motor?
If not, then they just have a conventional starter.

I don't think many vans have start/stop though I could be wrong.

More than likely.
