What is meant by initiating movement between signals?

Initiating movement between signals refers to the procedure where a train is allowed to start moving while adhering to specific operational protocols, particularly when conditions may not be optimal for safe movement. Moving at restricted speed is crucial in this context because it ensures that the train can stop quickly if there are unforeseen obstacles or conditions that require immediate attention. The restricted speed allows for enhanced safety measures, accommodating the need to react to signals, track conditions, and potential hazards along the route.

This method of operation emphasizes caution and safety, allowing for the correct assessment of the situation before fully committing to regular speed. In scenarios where full-speed movement is not advisable, the emphasis on restricted speed ensures that the train crew has the necessary situational awareness and control.
