I just saw a train go by and the cars did not have big open doors on the side. I've watched enough movies to know that trains are supposed to have empty cars with big open doors so you can run and jump the train, and then reach your hand out to your companion as they struggle to make it and just barely grab their hand and help them onto the train. Everyone knows that's how it goes, yet the train I saw had no open doors! Come to think of it, I've never seen an open side door on a moving train!!!!
