Yes but properly speaking Amtrak should have cross-country high speed rail routes and lower costs than flying. Amtrak can't even imagine high speed rail as long as they are stuck renting routes where they are limited to 140km/h, less than half the speed of high speed rail in other countries. Even Amtrak's fastest lines, the Acela in the NE corridor, only manage 240 km/h along one or two sections.
