What is the fouling point in rail switching?

The fouling point in rail switching refers to the point at which a train could interfere with the operations of another track. This is a critical concept in rail operations as it determines the safe distances that must be maintained between trains on adjacent tracks. When a train is on or past the fouling point, it risks obstructing other trains that may be approaching on parallel tracks, thereby increasing the risk of collisions or accidents. Understanding fouling points is essential for maintaining safety and efficient operations within a rail yard, allowing for better coordination among multiple trains operating in close proximity.
