Al, Dirk and Eva get on the train one at a time and the guard at the end of the train sees the now-riderless camels one by one. While Eva is getting on the train, the scene switches to view from the rear of the train. All three camels are seen close together. Shortly thereafter, the scene switches again to the view from the train, and the camels are separated by some distance from each other. The camels would not have been that close together unless all three people had boarded the train simultaneously.
