I considered that. I asked this question about 20 years ago, of course with the answer that we have plenty of oil, why change the current powertrain design.

I agree with you on a few points, but also have some rebuttal. It's true that a loco doesn't have a series of gears: some are geared for high-speed, some are for raw power, low-speed, and in-between, etc. But with the absence of a transmission in a vehicle, that's additional weight savings. A parallel engine/motor idea is pretty efficient, but my goal is weight reduction. With Metro's setup, many heavy batteries may be required to store a decent charge to get around. I'm not saying to stick a 0.7L Diesel hooked to a separate generator, but an all-in-one design like a larger household generator -- those little things can power a house. It's only a theory, and I'm sure the current draw would bog it down, but it's an idea. The forklift motor itself looks pretty darn heavy by itself.
