Researchers show economic, environmental and grid-resilience benefits of converting diesel trains to battery-electric

Green Car Congress

In diesel-electric trains, a diesel engine is connected to an alternator that then supplies electricity to electric motors connected to the locomotive axles. Retrofitting the trains to be powered by batteries is therefore feasible because diesel-electric trains already have an electric motor. Popovich, N.D., Rajagopal, D.,
