Today's train positioner-dumper systems are powered by drives capable of exerting 300,000 lbs of force and more than 365 hp. The article describes these drives and their operation. Rotary couplers at both ends of a car let it rotate without uncoupling from a train. Typical single dumper systems are unloading trains at a rate of 30 to 35 cars per hour; a system with multiple dumper units has been designed to unload trains of as many as 231 coupled cars in less than 2-1/2 hours. Single dumper systems are most common, and more than 35 have been installed in the free world in the last 5 years.
