What must be done to avoid fouling the main track during a restricted speed operation?

To avoid fouling the main track during a restricted speed operation, it is essential to keep a lookout for broken rails and obstructions. Restricted speed is defined as the speed at which a train can stop within half the range of vision, allowing the crew to react to any unexpected obstacles or track conditions. By remaining vigilant for potential issues such as broken rails, equipment, or other obstructions, the crew can ensure that safe stopping distances are maintained and that the train does not encroach upon areas where it could cause an accident or obstruct other trains.

Maintaining awareness of the surrounding environment is crucial in restricted speed situations, as it directly contributes to the safety and control of train operations. This proactive approach in monitoring the track helps prevent fouling the main track, thereby ensuring that operations proceed smoothly and safely.
