Only because of the speed of the train. Fuel spent accelerating to later brake is wasted fuel. More efficient would be spending only enough fuel to come to a full stop without braking.
Efficient from an electrical standpoint, but not a transportation one. You can’t “improve” it so much that it no longer does the thing it’s supposed to do.

So you want the trains to coast from station to station? Do you really believe that or is it very important for you to be right?
