I wondered about the same thing. The train was stopped in the middle of town and the crew members were talking to the local fire department. They apparently decided that it was wise to shut the engine down, which they did. The fire ceased immediately. I came back by about an hour later and the train was gone. They must have "pushed" the lead engine on to Atlanta. Can they even do that?
Why not? Throw it in neutral, Hook up and treat it like any other car.
