The part about trains sound really interesting. Do you mean that the energy gained through regenerative braking while a loaded train moves downhill is enough to move an empty train back up the mountain?
If so, how do they store the energy? Do the trains carry massive batteries, or do they draw power from (and contribute back to) the grid?

The regenerated energy is sufficient to power the empty trains back up to the national border." It's pumped into the grid.

- analog31 12y agoTrue. Oddly enough, I've been hiking in regions that were ski resorts during the winter, and they sometimes ran the chair lifts during the summer. We'd use them for hiking. There were some published hikes that involved lifts, buses, trains, etc. Perhaps out of a sense of sportsmanship, we tended to ride down, but never up.
