If the Dispatcher stops a train while it is moving through an interlocking, the train must not move in either direction until?

• A. It has received the proper signal or permission from the Dispatcher
• B. The train's engineer is replaced
• C. The interlocking is reset
• D. The conductor gives authorization

Answer: (A)

When a train is moving through an interlocking, its movements are controlled by the interlocking system and dispatcher authority to prevent conflicting routes. If the Dispatcher stops the train, the train must not move in either direction until it has received the proper signal or explicit permission from the Dispatcher to proceed. This ensures that the route remains protected and clear of any conflicting movements. Replacing the engineer, resetting the interlocking, or conductor authorization do not provide the required authority to move through a protected interlocking.
