Sounds possible. See http://en.wikipedia.org/wiki/Hybrid_train. I see it as a real possibility for lighter passenger trains. It might take development of special batteries for the heavier trains.

Energy & Dynamic Braking

Thursday, January 5th, 2012

Energy: you can’t destroy it, but you can certainly waste it. That’s what most motorized vehicles do, including trains. Usually, the energy generated when you stop a moving vehicle is dissipated as heat, and is lost to the atmosphere. With GE’s ecomagination we’ve discovered that you can capture and store that energy, then reuse it – that’s how our hybrid systems work. Watch the video to see a simple illustration of the physics behind dynamic braking. Keep in mind an object’s force is measured in newtons, using the equation force = Mass x Acceleration.
