A classification yard, marshalling yard or shunting yard is a railway yard found at some freight train stations, used to separate railway cars onto one of several tracks. First the cars are taken to a track, sometimes called a lead or a drill. From there the cars are sent through a series of switches called a ladder onto the classification tracks. Larger yards tend to put the lead on an artificially built hill called a hump to use the force of gravity to propel the cars through the ladder.

Not all cars can be sent over a classification hump. This Union Pacific track maintenance vehicle is permanently labelled "Do not hump", because it is not designed to withstand hump sorting.
The retarders grip the sides of the wheels on passing cars to slow them down.
CNW towerman R. W. Mayberry operates the retarders at Proviso Yard in Chicago, Illinois, May 1943.
A goods station or freight station is, in the widest sense, a railway station where, either exclusively or predominantly, goods, such as merchandise, parcels, and manufactured items, are loaded onto or unloaded off of ships or road vehicles and/or where goods wagons are transferred to local sidings.
