What is required when a train encounters an unattended fusee burning on the track?

When a train encounters an unattended fusee burning on the track, it is essential to stop and proceed at restricted speed until passing a specified distance, which is typically one mile past the fusee. The reason for this requirement is to ensure the safety of the train crew, passengers, and any potential hazards that may be present on or near the track.

A fusee serves as a warning signal indicating that there may be an obstruction or a dangerous condition ahead, and treating it with caution is necessary to avoid accidents. By stopping and then proceeding at restricted speed, the crew can maintain a heightened awareness of their surroundings and be prepared to take further action if needed. This procedure allows for the assessment of the track ahead to ensure it is clear before returning to normal operations.

Options that suggest ignoring the fusee or proceeding at normal speed disregard the significant safety implications that a burning fusee represents. Similarly, while signaling dispatch may be a prudent action in some situations, it does not replace the immediate safety actions required when encountering such a warning signal on the track.
