Battery powered cars, trucks and buses have now committed to battery operation, now that battery technology has improved. There was even talk of a battery powered airplane. The next transport to go battery would seem to be railroads. Battery power would appear to be the ideal "propellent" due to the carrying capacity of a rail car. Back in the late 1800's, a battery powered locomotive was demonstrated to the public; I believe it was in Germany. Battery power has been used in mining operations successfully. I think railroads would be a good candidate for battery power. The current explosion of battery technology could make railroads the next big user of battery power. I guess energy cost vs payload is a large consideration.
