Overhead powerlines work for a lot of rail, diesel-electric is a reasonable compromise I see used here, runs on overhead electric when it can, diesel otherwise. You can electrify the lines with the worst air quality first without having to electrify 100% of the network.
As for batteries, interesting idea, I wonder how far you would get with a fairly short range battery, or essentially turning the current diesel-electrics into plug-in hybrids. Helps that trains are pretty energy efficient too.
I was thinking a fully electric train, how much batteries would it take to match a regular diesel locamotive. I assume it would out would be multiple cars. One near idea is that each car would have it’s own battery and motors and the load could be shared and would scale very well.
