The GN, and other roads, had huge high-sided woodchip gondolas with end-doors. These were emptied by tipping whole car nearly vertical on a hydraulically-inclined section of track. The same idea is also used with large truck-trailers as you describe.toggle quoted messageShow quoted text
Even more extreme are the mechanical coal-dumpers used in many port cities, both on the ocean and in the Great Lakes. The entire car (sometimes a pair of cars) is grabbed, clamped, then raised perhaps 50 feet. Sometimes the car is elevated by pushing it up a ramp, and sometimes lifted with a vertical elevator. Then it is nearly inverted to dump the load. Quite rapid, very dusty, and very impressive.
