What is the function of a fouling point sign?

The function of a fouling point sign is to clearly define the clearance point at hand-operated switches. This is crucial in railway operations, as it helps ensure that trains do not encroach upon areas where switching operations are taking place. By marking the fouling point, the sign informs train operators of the safe distance to maintain from the switch to avoid interference with the switching mechanism or any personnel who may be operating the switches.

Understanding the significance of this signage helps maintain safety protocols in train operations and minimizes the risk of accidents. In instances where train movements are involved in the vicinity of switches, adhering to the clearance indicated by the fouling point sign is essential for operational safety.
