What if we figure out a way to safely transport people IN something like a missile, self propelled, and can be launched on a schedule. Then we wouldn't need the train at all!
Missiles are super inefficient. You have to overcome gravity while fighting air resistance at the same time, which requires unreasonable energy density
If only there was some way to use air resistance to fight gravity, or better yet even some sort of metal road to push against to lower required acceleration to the minimum...
Maybe if we made a super slow missile on rails? Never mind, this sounds crazy now that I say it out loud
