How does that work without batteries? Where does the energy go?
- ljf 3y agoBack into the power grid. Quote: When regenerative braking is employed, the current in the electric motors is reversed, slowing down the train. At the same time, the electro motors generate electricity to be returned to the power distribution system https://www.ctc-n.org/technologies/regenerative-braking-trains https://www.ctc-n.org/technologies/regenerative-braking-trai...

- blacksmith_tb 3y agoThe light rail MAX trains in Portland use regen braking without batteries, as one train is slowing it's generating power for other trains that are in motion[1]. 1: https://www.wired.com/2013/06/portland-light-rail/ https://www.wired.com/2013/06/portland-light-rail/
