That sucks the US closed so many electrified lines...
Sad, but economically inescapable. The interurbans succumbed to subsidized roads, GN to better tunnel technology, and the Milwaukee Road to a favorable market for scrap copper. The distances are just too great in the US for mainline electrification outside the Northeast.
I guess for people who value hope over engineering, we could try selling transcon electrification powered by solar cells and wind turbines (g) .
