It's funny you mention that, I had a similar thought a few weeks ago, though I was thinking about the difficulties of electrifying the freight railroads. What a lot of liberals, and most Europeans, don't understand, is that the nature of the US rail network is fundamentally very different than most parts of the world, and electrifying it is extremely impractical in a lot of areas, which is why locomotives have to be their own power plants. But here's the thing, locomotives don't give a shit about where they get their electricity, and added weight is good for tractive effort, so developing a battery that is practical (i.e. not what they put on gensets), and could effectively replace a prime mover in terms of weight and dimensions, means that you could charge the batteries any time the locomotive is in an area with overhead wires, and leave areas where the wires are problematic as-is (yards, remote branch lines, et c). Then you just swap out the power source the next time the locomotive goes in for a rebuild, add a pantograph, and bob's your uncle. It still doesn't solve the problem of where the power comes from, mind.The biggest challenge in terms of energy, as I see it, is that we don't have ways of storing a large supply of electricity like we can do with coal and oil. If we can find a safe, efficient way of banking large amounts of electricity, then we can solve a lot of problems. One of the unfortunate realities of our time is that most of the political left (middle class neoliberals) doesn't understand the power grid or how it actually functions, and they're too arrogant to listen to working-class people who do. Most renewable sources are only good for base load, and most current peak load solutions are problematic environmentally. The rapid startup, shutdown, and load changes that peaking plants have to perform favour fossil fuels and hydro power greatly, and both of those solutions create serious environmental issues. The current idea for the future is to use solar energy to store thermal energy that can later be used to generate steam for peak load applications. It might be a workable solution, but we're talking about using a lot of intermediary steps to accomplish what we really want: create a giant, reliable, safe, rechargeable battery that will be usable long enough to justify its construction cost.The thing that pisses me off the most about mass transit in the US is that auto ownership as a good thing is a relatively recent construction that belies the fact that owning a car is a massive pain in the ass. We used to have a great interurban rail network in the US, and if you want to understand how it fell apart, all you have to do is watch Who Framed Roger Rabbit.
