An idling gas engine may be annoyingly loud, but that's the price you pay for having WAY less torque available at a standstill.

The motors have never been the problem, it's always been the battery. See train engines, they are a diesel generator with electric motors.

This is where history pisses me off. We should have been headlong into battery research after the oil embargoes. Could have been 40 years faster.

pretty sure most trains are powered by either overhead wires or third rails? considering that urban rail systems are always electrified and those have A LOT of trains.

okay? i'm talking about the world though, so typical for people to just assume america is all that matters lmao

The point is about utilization of electric motors, if it happens anywhere on earth it's possible. You're trying to insinuate that it isn't true. And it is. Being American has nothing to do with it you dunce
