In the heyday of the all-electric Pennsylvania Railroad, a train going down a mountain regenerated power back into the lines to power another train coming up the mountain.
I played a lot with electric trains in my deformative youth. One of my fond childhood memories was a family vacation out east, where I got to see *real* electric trains in action. Seeing and hearing the mighty GG1 locomotive in action was an amazing experience. Yes, there are all sorts of alternative ways to run a railroad. Alas, innovation seems to be a dirty word in the US.

Perhaps if you wanted to have a fully electric locomotive maybe it might be useful (at least in the beginning) to only electrify the mountain areas? That might start the process. These all electric locomotives could shuttle back and forth as "helper" locomotives. Go up the mountains. Disconnect...and wait for the next train that is going down and provide "brakes"/regen into the grid on the way down. Then as you said, you'd only need a limited amount of batteries probably to change direction and stuff...
