The guy that taught my Conductor, and later, Engineer class, had 31 years on the Union Pacific as a trainman and manager....he had some crazy stories.
When he hired out as a switchman in a large yard in Texas, things were much different in the early 1970's than they are today. He told us the first time he saw a railroad related incident, the yard foreman was helping kick cars (the engineer pushes on the train, building slack in the couplers, the switchman pulls the pin, the engineer abruptly stops, while the car rolls free into the many tracks the other switchman are turning as fast as they can to build trains). Supposedly this guy was not one for safety, and it really showed that day, while kicking cars, so he was sent down the rail to couple cars that did not couple correctly while being kicked. He had the hoghead pull two cars apart to lift the pin, and stick it up so they could be coupled. The engineer either got the wrong signal, or some form of miscommunication happened, the the guy got coupled between to cars. They called the paramedics, and his wife down o the yard. The guy was still coherent, but they all knew from hearsay, that as soon as the cars were uncoupled, he was going to expire. The Superintendent told his wife that she had better go say goodbye to him, which she did for several minutes, then they ushered her away. Jerry, my friend that taught my two classes, had to pull the pin on the car to get his friend out of the couplers. He said that he didn't make it but a few minutes while the paramedics tended to him.
