Perhaps an all-electric train could, do they just feed it back into the grid? Freight trains mostly use air brakes, which are friction.

- liability 6y agoA diesel-electric freight train locomotive can use dynamic braking by dumping the electrical energy into a bank of resistors (known as rheostatic braking, opposed to regenerative braking, but collectively called dynamic braking.) However apparently this form of braking is only a small portion of braking that freight trains do since only driven axels can participate in it and most freight cars are unpowered. I didn't consider that.
