In the original 1955 airing of the episode "The Great Train Robbery" there was an extra scene involving the Mertzs. After getting on the train the Mertzs tell the Ricardos that they're heading towards the dining car for something to eat. After they leave the Ricardos, there is a montage of scenes showing the Mertzs going into the dining car and being escorted to a table on the second floor of the car where the dome viewing area is. All subsequent airings of this episode omit the scene but a rare 16MM print of the episode, with the scene intact, restored it for the season five DVD release of the show in 2005. The scene was cut from television airings because it was out of sequence with the story. If you look closely at the domed windows of the dining car, you can clearly see the reflections of lights passing over them, simulating a train that is moving at a pretty good speed. However, this scene was placed in the show at a time when the train that the Ricardos and the Mertzes were on had not even left Union Station in Los Angeles. After the Mertzes are seen in the domed dining car of the moving train, the station master announces the departure of their train from the station along with a shot of the train pulling away from the platform in a later scene. Union Pacific Railroad provided Desilu Productions with assistance for several scenes in this episode.
