Not really a "bad order," but I was on a sleeper that was involved in a (very minor, thank God) derailment a couple Januaries ago in an ice storm in St. Louis.
It was kind of chaotic figuring out what to do because it was the middle of the night, we were (mostly) half-asleep (I had JUST fallen asleep when they knocked on my door and told me I had to leave). We sat in the lounge car for a very long time. They tried to get us rooms on the other sleeper but none were left. So, the first thing that happened, the conductor thought he had permission to leave an empty coach on, and we could all go in there and have the coach to ourselves (the 15 or so people who had been in the sleeper). Probably the best solution at the time. I think I got about an hour of sleep there stretched out between two seats.
BUT - before Amtrak got going again (this all happened at St. Louis), they decided they had to remove that car. So the conductor came back again and routed us out of the empty coach and told us to "go find a seat in one of the other coaches." We had had SOME assistance with luggage and such the first go-round, the second time we had to move everything ourselves - and in a hurry. The train was nearly full so it was no picnic trying to find a seat.
I only got a seat because a woman traveling with small children saw me standing, bewildered, in the aisle, wondering if I could just sit on the floor, and she moved her child out of the seat she was occupying (she had moved the child from the seat next to her to have more room). But it was frustrating how little help Amtrak gave us in finding seats at that point - it was like 1 am and I was very leery of waking up some stranger to ask if they would sit up so I could have the seat next to them. (Also, that night in coach reminded me why I pay the cost of the sleeper! There was an exceptionally loud snorer a few seats over and even earplugs didn't block the sound out). We were some 9 hours late getting to Mineola (my destination). I wound up renting a hotel room for the night as I was way too tired to drive the 2 hours safely to get home.
In retrospect, I think they should have offered for us to stay in the lounge car - it was one of those big Viewliner type lounges. But no one suggested that and I didn't want to settle in again just to be told to move a third time.
It was a giant effort (involving several calls to customer service) but I did get a refund of the sleeper car cost of the trip, and a $75 voucher.
I also weathered a "bustitution" caused by flooding in and around St Louis - Little Rock several years ago. That was an even bigger nightmare - 18 hours on what amounted to a city bus, with loud movies being played all night long.
I really hope that's the extent of my "unexpected" adventures with Amtrak.
