Perhaps instead of calling for a new autotrain, we should be calling for Amtrak to actually run its normal trains on a usable schedule.
Outside of the NE corridor, I have not encountered a usable schedule. 3 days a week, once a day, per direction is not usable. That's barely even
service.
If Amtrak could run a train like the Cardinal at least 5 days a week, 2x a day (once per direction), minimum, then that would be a great leap forward. Unless I'm going to a park, my destination is going to be in a city. Amtrak almost always goes to those cities, and train stations are almost always more convenient than landing at airports. Some places I have driven/trained to are over an hour away from the nearest major airport. If Amtrak would just RUN REGULARLY, it would be more convenient than driving for most of my trips. I wouldn't be the only one who would experience this convenience. If Amtrak could get its service in gear, we wouldn't need these advocated autotrains as the train would largely cancel out the need for driving. If, once one arrives at his destination, light rail or foot wouldn't get him to where he needs to go, there is always car renting.
I found that I had need to go to Huntington, WV for a weekend in the future. So I checked Amtrak, remembering that I had been there when I rode the Cardinal a while back. The best Amtrak could give me is a Wednesday departure, with an incredibly late arrival, and there was no way back until the middle of the next week.
While Amtrak would be far cheaper than driving (unless you're carpooling, it almost always is), the extra hotel fees would cost far more than the gas would.
While we're at it, we need to get Amtrak's speed up. I recall seeing an Amtrak average speed listing of 48 mph, and that calculation was made only when the trains were actually moving. (ie: only the time in motion was used, not the time sitting stationary on sidings or at stations, so this average is actually higher than it could be.)
Few car carriers are simply attached to existing train and train carries both regular passengers and auto riders.
Forget that, instead put on more sleeper cars so that long-distance train travel is practical for the "average joe". Long distance coach isn't a real selling point, and on certain trips even a roomette can cost 3x as much as a coach trip. A sleeper car makes more sense, as it doesn't take a beaucoup of extra time nor special facilities to load up. Unlike auto carriers, there's a much greater demand throughout the Amtrak system for sleeper cars.
I find it ironic that the heavy-handed government regulations of yesteryear are holding back the government transit venture (Amtrak) of the present.
