What is the purpose of a "restrictive signal" in rail operations?

A restrictive signal serves an important function in rail operations by indicating that caution is required as a train approaches a switch or other potential hazards on the track. The signal communicates to train operators that they must proceed with reduced speed and be prepared to take appropriate actions, which may include stopping if necessary. This cautious approach is essential for maintaining safety, especially in areas where train movements could encounter conflicting traffic or where track conditions may require careful navigation.

The role of a restrictive signal is crucial in ensuring that all personnel operating trains are aware of the need to be vigilant and maintain control over their train's movements, thereby preventing accidents and ensuring a smooth operation across the rail network.
