An electric train may require less energy because it doesn't need to move the engine along the track.

It also doesn't need to move the fuel it needs, either. Plus if cleaner fuel becomes available, it can switch as soon as it's hooked to the grid.

Correct. They can also return energy when braking, although it usually helps to have a decent density of trains running at the same time.
