In single track territory, what must be done if a train finds a fusee burning red on or near its track?

When a train encounters a burning red fusee on or near its track in single track territory, it is critical to take immediate and appropriate action. The correct response is to stop the train and extinguish the fusees before proceeding at restricted speed. This procedure is essential because a burning red fusee indicates a signal to the train crew that there is a danger or obstruction ahead.

Stopping allows the crew to assess the situation and ensure that it is safe before continuing. Extinguishing the fusees is necessary as they may cause confusion for following trains or could be indicative of an ongoing unsafe condition that must be resolved. Following these steps ensures the safety of both the train crew and any potential hazards on the track ahead, aligning with operational protocols designed to prevent accidents and ensure safe rail operations.

In contrast, proceeding without stopping would disregard the warning indicated by the fusee, which could lead to accidents or collisions. Calling for assistance is not the immediate action required when a fusee is encountered; it is more important to ensure the immediate area is safe first. Continuing with caution without first stopping and extinguishing the fusees would not be sufficient and could compromise safety.
