Where must movements be made at Restricted Speed?

Movements at Restricted Speed are specifically required on tracks that are not governed by Automatic Block Signals (ABS), Direct Control Signals (DCS), or Interlocking Rules. This is crucial for maintaining safety in areas where the conventional signaling systems that provide greater control and indication of track conditions are not in effect.

When operating under Restricted Speed, the operator must be prepared to stop unless the track is clear, which enhances safety by allowing for controlled movements in potentially less predictable areas. This is especially important in locations where obstacles might not be visible or where the train crew must be particularly vigilant for unexpected conditions, such as work zones or other vehicles on the track.

In contrast, tracks that are governed by ABS, DCS, or Interlocking Rules typically have more stringent operational guidelines and signal systems in place that inform the crew of track conditions, making Restricted Speed less applicable in those situations. This reinforces the importance of knowing where Restricted Speed applies to ensure safe operations in diverse track environments.
