The Jordan spreader was used primarily for ditching along the right of way. I never saw it used for snow, but it could have been used for ballast before the advent of the mechanized ballast regulator they use today. What the Jordan spreader usually did best was to derail. I have used them many times on work trains, and the [not allowed]ed things spent more time derailed than they did working. The blades would just twist or lift the wheels off the rail. / Ron
PS, they were not working the Jordan spreader when it derailed at the Junction. They were just moving it on a train. I don't know what caused that derailment, but I remember Brown Eyes Hubertz was the engineer.
