How may your train be authorized by a stop indication at a manual interlocking?

• A. By the dispatcher giving permission
• B. By the conductor's signal
• C. Contact control operator who will give permission when the route is properly lined and no conflicting movement is occupying or authorized to enter the track between that signal and the next absolute signal
• D. By proceeding at restricted speed

Answer: (C)

At a stop indication in a manual interlocking, you’re not authorized to move until someone in control confirms it. The train drawer of this interlocking—the control operator—must grant permission after verifying the route is properly lined and there’s no conflicting movement occupying or authorized to enter the track between the current signal and the next absolute signal. This explicit authorization ensures the route is clear and safe before you proceed.

Dispatcher permission isn’t the mechanism here, and the conductor’s signal isn’t the authority to enter the interlocking. Merely proceeding at restricted speed isn’t authorization by itself; you still need the control operator’s clearance to move.
