I don't know about reliability but there does seem to be a trend of every
new electric train in this country using more power than its predecessor.
In the case of the 377s significantly more. This is in stark contrast to
cars which despite getting heavier year on year are still using less fuel
with each generation. Whatever the train builders are concentrating on in
their designs, energy efficiency doesn't seem to be it.

Cars potentially use more and more energy on more and more gadgets just
like trains, but have significantly more efficient engines year on year.
You might be able to apply some of the engine-improvement technology to
DMUs, but can electric motors be made any more efficient?
