An American train service from the 1970s where passengers could take their cars with them in special rail cars that were connected to the passenger coaches all the way to Florida from outside Washington D.C., and for a brief time Kentucky. After going bankrupt in 1981, Amtrak took over the operation 2 years later and rebranded it as "Auto Train", which still runs today.
Dad: The family's going to Disney World!
Mom: Ugh, I'm not looking forward to sitting in a car for 3 days.
Dad: We're not taking the car, we're going to ride the auto-train all the way there!
Son: What's the auto-train?
Dad: Well, it basically means we get to relax in luxury aboard a special train, and we don't have to drive! They even have on-board movies, dining and beds!
Mom: I'm on board for that!
