Lest we forget, there was once a Louisville-Lorton private sector Auto Train. It flopped; and that was even after it was combined with Amtrak's Floridian. As I recall, that was gone before the Floridian's demise as part of the '79 Carter Cuts.
It's no wonder; the journey was simply too long. I've noted here that if the AT has not arrived by Noon, "arewethereyetitis" becomes quite endemic
. AT passengers are not railfans; they are not even non-fan train lovers. They are people who want to get themselves and their auto (often "loaded to the gills" with stuff for an extended stay) in a painless way between the Northeast and Florida. Sure, there are competitive trucking services where the auto's owner will simply fly down and back. But how about "the fun" of doing without your auto for maybe twenty-four hours while the truck catches up? AT sure seems more convenient, for your auto is never more than a train length away from you.
Now I want to reiterate my "ditching" of AT (I "go down" every year and will do so long as God grants me my health) was not brought about by any "horror story". In fact on my final journey aboard #52(the day Kobe Bryant was killed), "everything worked", the Attendant was simply "wondeful", the food "edible" (even if their "comp" wine served by an Attendant carrying milk bottles and saying "you get one glass; Red or White?"; I passed on "Continental Breakfast as I knew of a MickeyD essentially at the corner of Lorton Road and Jefferson Davis Highway US1), and arrived Lorton one hour early!. But the experience was simply a "meh" - and it has become too expensive for such, considering the only 400 miles of driving - and no time whatever- saved.
