Hitachi Limited has developed a wagon speed control system that uses linear motor power. Sidings fanning out from the hump are equipped with a reaction plate and light running rails on which linear motor-powered Trolleys travel. Retarders are program-controlled by a small computer, or can be remote-controlled by radio. As a freight wagon leaves the trolley units travel with the wagon for a short distance, boosting or retarding its speed according to the computer's instructions.
