What about a mechanical sling shot system at each sub station?
As the train arrived it gets slowed by a spring or similar system which is then used to propel the train forward once it needs to depart.
Also, what about just slower trains? The heat produced while acccelerating or braking is probably not exactly linear with the speed of the train.
- jdmichal 9y agoIt would probably be simpler to use regenerative braking like a hybrid car. The trains are already electric.
- cjrp 9y agoIt says in the article they convert some of the heat caused by braking, but I thought regenerative braking meant you also didn't have to brake as much.
- jdmichal 9y agoYour don't have to engage friction-based brakes as much, yes. And since friction-based brakes work by converting movement to heat, that's why regenerative braking helps with heat.
