The rail companies are really resistant to electrifying lines. I think because they are focused on cutting costs and spending money would cut into profit. Unfortunately, that means that the government will likely have to pay for it or force them. They have been looking into battery electric locomotives which don't make any sense except for switching yards. I read recently that there are electric and diesel locomotives which can use overhead power where available and switch to diesel when it isn't. That has the advantage that they can electrify lines incrementally.
