What must the control operator state when issuing joint track and time?

When issuing joint track and time, the control operator must state the identities of all movements in the overlapping limits. This ensures that all parties involved are informed of the specific trains, equipment, or movements that may be present in the area where track and time are being granted. By providing this information, it allows for clear communication and coordination between different operators and dispatchers, minimizing the risk of accidents or conflicts on the track.

Understanding the identity of movements is crucial, as it allows for the safe management of train operations within shared or overlapping territories. It ensures that everyone is aware of the current situation and can make informed decisions regarding train operations. This practice enhances safety protocols and promotes effective rail operations, ultimately leading to more efficient use of the track infrastructure.

Other options, while important in their own context, do not specifically pertain to the essential requirement of identifying movements when granting joint track and time.
