Amtrak! In the early '90s my girlfriend and I decided to go from DC to Chicago for Christmas via Amtrak, about a 12 hour trip, I think. The train kept stopping then moving for a bit at a time in the middle of nowhere until eventually we were told the tracks were frozen. The heat went out, the toilets backed up, and the train ran out of food before we finally rolled into Chicago after almost 30 hours.
But then — I know what you're thinking, "Fool me once..." — a couple of years later we tried it again and you guessed it, same thing. Frozen tracks, no heat, backed up toilets, no food (except what we brought this time), and arrival after around 25 hours.
