When I was little, I saw a movie overseas that Andrew McCarthy was in where at the end he and the girl were on a railroad track on one of those handcar, maybe running away. This was in the 1970s and I don't have a clue what the name of the movie was and I haven't been able to find it. Anyone?
Andrew did not start is film career until the 80's. Could you have mistaken him for someone else. The only movie I can think of where at the end of the film he is with a girl near a train is the movie Kansas. In the late 90's he is also leaving on a train by himself in the film I'm Losing you.
