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.
