What does WSS stand for in railway terminology?

In railway terminology, WSS stands for West Siding Switch. This term refers specifically to a switch or turnout located on the west side of a railway line that allows trains to switch tracks from the main line to a siding. The function of a siding is to enable trains to pass each other or to hold stationary trains while others continue on the main track, thereby enhancing operational efficiency.

Understanding the significance of a siding switch is important for railway operations, particularly in managing train traffic and ensuring the safety of operations on busy lines. Knowing the specific terminology helps maintenance of way personnel communicate clearly and effectively about track configurations and operational procedures.
