Do subway trains have batteries for the purpose of moving themselves? I don’t know much about subway trains specifically, but in my imagination I can’t picture one working during a power outage.
If they don’t carry large batteries then it makes perfect sense to me to dump the energy back into the grid. Electrical losses should be fairly small.
