In the old days, regenerative braking used the monetum of a descending train to pump electricity back into the wires to help ascending trains. When diesels came along, it became dynamic braking because the generated electricity was wasted as heat. My question now is: has modern diesel loco technology advanced to the point that they can indeed put a useful amount of energy back into the loco's batteries? How big are they? Where are they? What voltage are they? Or, more probably, was it an error on Lynn's part, to which I was responding with tongue-in-cheek?
