Under which condition is the Dispatcher not required to notify when entering DCS territory?

• A. Entering at an interlocking, controlled point, or TBS.
• B. Entering DCS territory at the start of the run.
• C. Clearing the limits of authority.
• D. When verbally relieved by the Dispatcher.

Answer: (A)

When entering DCS territory, the need for dispatcher notification depends on how you enter. If you’re entering at an interlocking, at a controlled point, or through a Time-Based Signal, the movement is already governed by automatic signaling or timetable guidance, so the dispatcher isn’t required to provide a separate notification. This is because authority to proceed is established by the control system itself rather than by a verbal clearance from the dispatcher. Entering at the start of the run, clearing the limits of authority, or being verbally relieved by the dispatcher all lack that automatic signaling-based authority, so those situations would require the dispatcher to notify or clear you before you proceed.
