Before entering OCS limits, which entity must always be consulted?

Consulting the train dispatcher before entering OCS (Occupancy Control System) limits is required because the dispatcher maintains control over the track and ensures that it is safe for entry. The dispatcher has real-time information about train movements, work activities, and the overall status of the rail network, which is crucial for preventing accidents and coordinating safe operations.

While other position holders like station masters or regional managers may have roles in the broader operational context, they do not have the direct operational oversight that the train dispatcher possesses in regard to OCS limits. This makes the dispatcher the essential authority to contact, ensuring that all safety protocols are followed before any entry occurs.
