How must trains operate when within view of another train under restricted speed?

When trains are operating under restricted speed and within view of another train, they must proceed cautiously. This means that the engineer should be prepared to stop short of any obstruction, recognizing that visibility may be limited and risks may be present. Proceeding cautiously emphasizes the need for vigilance and the ability to react to any unexpected conditions or obstacles on the track.

The concept of restricted speed inherently requires that the train does not operate at high speeds, allowing for safer management of any potential hazards. As the term implies, restricted speed is a lower speed limit, ensuring that the train can stop within a distance that is visible to the engineer, thus maintaining safety in operations where other trains may be in proximity.
