Other forms: sidings
A siding is a short side track where wagons are left. Shunt into the siding, a goods siding, the siding is full.
It comes off the main line and usually ends in a buffer, so it is for storing rather than for going anywhere. Shunting stock into one clears the running line, which is the whole point. In America, siding also means the boards on the outside of a house.
