Which system controls the interlocked switch used by Montauk westbound trains when upgrading into the 10 extension?

• A. Central Dispatch
• B. Hillside Yardmaster
• C. JCC
• D. Jamaica Yardmaster

Answer: (C)

Interlocked switches are controlled by a centralized interlocking system that coordinates the route, signals, and lock release to prevent conflicting movements. For a Montauk westbound train upgrading into the 10 extension, the authority and system responsible for setting and locking that switch is Jamaica Central Control. This center oversees the interlocking around that area, ensuring the switch is properly lined and locked before the train proceeds and that signals agree with the chosen route. Central Dispatch would issue movement authorizations but does not directly operate the physical interlock. The Hillside Yardmaster handles movements inside Hillside yard, and the Jamaica Yardmaster manages movements within Jamaica yard. The system that actually controls the interlocked switch in this scenario is the Jamaica Central Control, making it the best answer.
