 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 theyre 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.
