RTC is responsible for which action related to Track Authority?

• A. Approving the OK time
• B. Scheduling maintenance crews
• C. Issuing track authority documents
• D. Verifying and approving the OK time for Track Authority

Answer: (D)

The action being tested is how the timing of a Track Authority is regulated to keep operations safe. The OK time is the moment the Track Authority becomes active, so it must be precise and free of conflicts with other authorities and current track occupancy. The RTC’s role is to verify that proposed OK time is correct, safe, and coordinated with everything else in the system, and then approve it so the authority can be used. This ensures trains won’t enter a block when another authority is already in effect or when the track isn’t actually clear.

Issuing the TA documents is handled by the authority that creates the instruction, not the RTC. Scheduling maintenance crews is a separate function unrelated to approving when a Track Authority goes into effect.
