Yep. I once fell asleep on train 14 after Oakland, I woke up in Chico, 4 hours late.
Honestly not sure what happened. What I have been told happened was that a person was escorted off the train, and then climbed on to the side of the train and fell. It might have just been a trespasser on the tracks, I don't know.
But we had missed our slot and were stopped for four hours at Klamath Falls because UP was doing track work. Ended up having dinner close to Chemult, and we got into Seattle before 5 AM.
