Does anyone know of another efficient mode of transportation that has near-zero surface friction?
Because that would be a gamechanger
Maybe there’s some kind of a wheel, like a metal wheel that could just glide across narrow metal surfaces that could follow a set path….
imagine if it had a flange, so around turns the wheels could hook into the the metal surfaces so they wouldn't go off them, that would sure be neat
Actually the flanges are only an additional safe guard. The train wheels are actually a bit cone shaped which makes then self-centering on their own, even without the flange: https://youtu.be/Nteyw40i9So

Oh! You must be from the land of the free! I'm sorry...
