How is occupancy verified in Track Warrant Control?

• A. The crew and dispatcher monitor the train’s location and progress within the stated limits, using position reports, track signals, or other monitoring systems.
• B. Only the dispatcher monitors.
• C. Only the crew uses a handheld device.
• D. Visual inspection from a central tower.

Answer: (B)

In Track Warrant Control, the dispatcher is the central authority responsible for verifying occupancy. The dispatcher keeps track of all warrants and movements in real time, using position reports from trains, signals, and other monitoring systems to ensure that no two trains occupy the same block and that movements stay within the authorized limits.

The crew operates under the issued warrant and reports their position as required, but the actual verification of occupancy and prevention of conflicts rests with the dispatcher. This centralized approach helps maintain safe, coordinated movement across the network.

Other options imply that occupancy is determined by the crew, handheld devices, or a distant visual check, which do not reflect how Track Warrant Control is designed to function.
