What is a switcher?

A yard switcher, sometimes called a yard jockey, works in the trucking or railway industry. Their primary job duties are to move trailers or rail car beds around the yard, preparing them to load or unload cargo. The yard switcher makes sure that the area remains clear so traffic can pass through easily. A switcher works in the freight yard rather than as a truck driver or train operator, although they should be familiar with driving a tractor-trailer semi, locomotives, or other specialized equipment.
