They could even run a mixture of diesel & electric. Just need a place to store trainsets & service them.
I still wonder if battery-electric trains might be the answer.A battery big enough for an 8-coach Commuter Rail train would be very, very expensive and much heavier than the equivalent energy in diesel. So no.
