I would like to put a little nuance in the answer given by Mr. Jeanes concerning the electrified system of high-speed rail. Yes, it's true that electrified high-speed rail would be much better for the environment than diesel locomotives, but it all depends where the electricity comes from. If comes from a coal plant, I'm not sure we're going to be in the place we think we should be.
