Even if they were to power it from a nuclear plant, there is growing controversy over nuclear waste.
Basically, you get to a point where the nuclear fuel rods are no longer potent enough to make dry steam for the turbines, so the plants can't use them anymore, but they are still plenty radioactive and plenty dangerous... So we bury the stuff in deep mountain caves.

I definitely could see something like a Prius type locomotive working. Maybe a small high efficiency motor to reduce the battery drain even if it doesn't have enough capability to fully recharge the batteries under high load?
