for these uses. Development seems to be on-going, and
the biggest shot of energy needed is to accelerate
the vehicle out of the station and up to cruising
speed. Maintaining the speed of a train doesn't take
very much energy (due, of course, to its high efficiency!),
and the capacitors are most efficient when the loads are
light. So, I think it could be feasible for local train
service as well.
