Which component has the ability to shutdown power to the entire Skyway Express system at once or in sections?

• A. Substation A
• B. Breaker Room
• C. Automatic Safety System
• D. Control Center

Answer: (D)

Shutting down power in a controlled, coordinated way—whether for the whole Skyway Express or just a section—is managed from a single operations hub: the Control Center. This is where operators monitor system status, receive fault information, and issue deliberate shutdown commands. The Control Center can coordinate with substations and the switching gear in the breaker rooms to de-energize the entire network or isolate specific segments safely, ensuring a controlled sequence that protects passengers, equipment, and the grid.

Substations mainly supply and step down power to distribution points, and the breaker room houses the equipment used to physically break or re-establish circuits, usually under the direction of the Control Center or in response to automatic triggers. An automatic safety system can trip breakers automatically to protect against faults, but it operates to safeguard the system rather than to execute centralized shutdowns on demand across the entire network.
