DO NOT HUMP GENERATOR

No, I'm not making this up. There really is a sign that says "DO NOT HUMP." When did this become a problem? It also seems like it might be a little uncomfortable! Actually this is a sticker that was applied by railroad company's to warn against damaging the generator from a practice called HUMPING. Some switch yards use a hill or "Hump" to sort rail cars. A string of cars are detached one at a time and pushed over a hump. The hump accelerates the cars and a person in the switching station sends the cars to the proper rail in the yard by electrically switching the tracks. In the case of the generator, a sticker saying "DO NOT HUMP" was placed on it so that the yard personnel would set the rail car with the generator aside for special handling. Sometimes the practice of humping damages loads because there is no control as to how fast the car will travel once it's humped.
