There was some old movie I once saw a scene of, maybe it was on TCM. All I remember (I am a train buff after all) was one scene where people were talking about getting on the subway in New York at 14th Street for one stop to West 4th Street, and then transferring. Then you saw them actually get on the train. Any help would be great. I do not remember if it was in color, but there is a good chance it was B&W since it was old.
