What does SXO represent in railway operations?

The designation SXO in railway operations stands for South Crossover. This term is vital in railway terminology as it indicates a specific track configuration that allows trains to switch from one track to another in a southward direction. Crossovers are essential for ensuring safe and efficient train movements, especially in complex track layouts where trains need to change tracks for various operational reasons, such as avoiding a blockage or facilitating traffic in station areas.

In this context, understanding what SXO represents is crucial for maintenance of way personnel, as they must recognize various operational signals and track designs to effectively manage train movements and maintain safety on the railway network.
