I’ve sometimes thought that AMTRAK should change its model to something like in the old days and include a one or two passenger cars with some cargo trains (almost anything not hauling pigs or cows, goes without saying) AND also include a car transporter for the passengers’ cars. Thus when they arrive having not had to drive they have their ow car unloaded (and washed / gassed up?) valet style and have free mobility at their destination.
Do so in corridors where the drive is long and tiresome (or the traffic is just always bad) but the train ride not so long it would be a hassle.
The secret is NOT necessarily faster trains but more departure times and more destinations ... which can be more easily accomplished with hybrid use trains ... combined with the ease of using their own cars.
Lookup the Auto-Train from Virginia to Florida.
