Cool, but come on, put some over head wires up!
I wonder if overhead wires make sense with the state of battery technology now? It must be cheaper to build battery-powered trains than install and maintain all that infra before you even factor in the cost of adjusting bridges and tunnels to accommodate the overhead wires.
Unlikely. Batteries are still incredibly expensive, also heavy and a consumable item (need to be regularly replaced). Overhead wires don't work for 1 train, but for all of them. They are also a mostly permanent installation with comparatively cheap maintenance (they are just steel+paint for the most part).
It's surely fine for a fringe route, where a train or two runs, and that would need electrification for a lot of track. So I'd assume there's a break even point somewhere.
