People keep on forgetting the immense density of America across it's East Coast: https://en.wikipedia.org/wiki/Northeast_megalopolis https://en.wikipedia.org/wiki/Northeast_megalopolis The northeast corridor accounts for 60M(!) people in the United States and yet the rail options are expensive and slow. it still boggles my mind that flying from Boston to NYC was cheaper by flight than train. While the US is geographically immense, the population is actually concentrated pretty well. Obviously rail doesn't work everywhere but if we had rails serving the Northeast Corridor, Texas (Austin, Dallas, Houston), California Coast (San Diego -> SF) we would have lines serving highly trafficked and dense areas.
