摘要：The article contains a model of wagon rolling down the hump profiles. It deals with motive and resistance forces. These forces made it possible to mathematically describe geometrical parameters of hump profile and kinematical characteristics of wagon movement depending on time. The conditions have been formulated, which makes the wagon movement down various marshalling hump profile sections possible. These conditions enable slowdown of the wagon as it moves from one hump profile element to the other until it stops in the hump-yard.
