Here's an idea: Build battery packs into ISO containers and hook up whatever you need on cars modified with appropriate wiring. Swap the battery just like you'd load and unload the containers!LTLFTcomposite said:I wonder how far you get with a locomotive pulling a train with 2484 kWh. I bet they don't use much once you get them rolling.
LTLFTcomposite said:Besides, locomotives use DC traction motors, right? Weight and size wouldn't seem to be an issue, since you'd have a big savings on weight and space with no engine, fuel tanks, generator, or rectifier stuff to accommodate all those batteries.

I thought the Leaf motor was AC.
Imagine the regenerative braking on that sucker when towing 200 cars!dznit said:http://www.popsci.com/environment/article/2009-10/worlds-first-all-electric-locomotive-has-over-1000-batteries-can-run-24-hours-single-charge

Does that have electric motors driving the screws, or does the steam power from the reactor run turbines that drive the screws through reduction gears? Not that it matters, it's bad ass either way.
