A siding is a section of railroad track which splits off from the main line at a switch, runs parallel to it for a distance, and rejoins it farther down the track. Not to be confused with a branch line or spur.

Sidings are used for many different purposes, including crew change, car/equipment storage, or for a slower train to give right-of-way to a faster one.
