Railway travel has schedules you have to adhere, and all the boarding/unboarding overhead, and luggage limitations.

With the high expense of rail infrastructure (e.g. transporation in cities) I always wondered if you simply designated a dedicated paved lane for busses if that would simply be cheaper.

Buying tix online makes rail travel a lot simpler, ektually. But there's a place for buses too, and a crossover point where increased traffic makes rail better long-term.

But long-dx on buses is no fun. Trains rule. Get some shuteye, or watch the world go by.
