UK-based YASA has just built a tiny electric motor that makes Tesla motors look like slackers, and this invention could potentially reshape the future of EVs
Quite the opposite, you want the locomotive to be as heavy as possible without exceeding axle or track load limits. The heavier it is, the more weight it can pull before slipping the wheels.
Assuming that flying with an electric motor is a viable option (I have zero clue, but from what I heard currently its not that realistic that we will get electric planes)
The main weight in an electric plane is a battery, and the energy density in that isn’t good enough yet, and it’s possible that it can’t be better with the current batteries we have, and we need a battery on a different set of elements
Trains don’t benefit much from lesser weight.
Drones, and planes are the most likely to benefit from this.

Small electric planes already exist. But yeah not passenger planes or to go any useful distance for the foreseeable future
