The Locomotion Interruption - S8-E1
Corrected entry: Sheldon says he was in a fire while taking a train through Des Moines. The largest Des Moines in Iowa has not had passenger rail service since 1970, and the much smaller Des Moines in Washington and New Mexico have never had it at all.
The Locomotion Interruption - S8-E1
Corrected entry: When they're driving back from Arianna, the road is a stupidly big bend for several shots, then the shot changes and it's suddenly straight and a much lighter tarmac.
Correction: After Amy says "How could you leave like that without saying goodbye and then call Leonard instead of me", and the shot changes to Sheldon looking at Leonard and then back to the three of them, it can be seen in the background that at the turn, the tarmac quality actually changes. Thus it is originally there and the footage is continuous.
Correction: There may not be a station operating in Des Moines, but there are passenger rail tracks that go through it, stopping at Osceola. The fire could have happened on the train, as he does not specifically mention being at a station there.
