ABSTRACT OF THE DISCLOSURE: This invention relates to the design of mar- shalling yard with upgrade speed control system. The principal difference between this yard and the conven- tional marshalling yard with downgrade only profile is described hereunder. Unlike the already known yard in which many speed control devices are installed on a down- grade to consume excess energy of cuts, the yard in the invention has an hump height designed by taking operating conditions of moderate runners as a base and is provided with at least one upgrade speed control unit consisting of one upgrade section and a necessary number of boosters and retarders on the downgrade profile. This upgrade control unit could convert excess energy of cuts into potential energy. The invention could raise hump operating capacity of marshalling yard at a considerably reduced cost.
