W R O N G.
In North America, a siding is a place named in the time-table where trains meet or pass each other.
A stub ended track, either industrial or in a yard is a _spur_ NOT a siding. "Siding" is what model railroaders frequently and incorrectly call "spurs".
Even an industrial track connected at both ends to the mainline yet not named in the time-table and not used for passing or meeting trains is a double connected spur, it is still not a siding, even though it looks like one.
