Barcelona is using the regenerative braking of its subways to power trains, stations, and neighborhood EV chargers. Could New York do it too?

    It also reduces brake wear on the trains, so they’ll need new brakes less often, and it improves air quality in the stations. Most of that black dust you see is brake dust. And you’re breathing it in, too.
