What must a crew member do before proceeding from a stop indication regarding dual control switches?

Before a crew member proceeds from a stop indication, it is crucial to examine and ensure that the dual control switches are properly lined for the route. This step is essential for maintaining safety on the railway and ensuring that the train is directed onto the correct track. Dual control switches require careful attention because they can be operated manually or mechanically, and any misalignment could lead to a dangerous situation, such as a derailment or collision with another train on an incorrect track.

Ensuring that the switches are correctly lined confirms that the route ahead is safe and that the train can progress without encountering obstructions or running into trouble. This practice is a key aspect of safety protocols in train operation and reflects a thorough understanding of the responsibilities that come with operating in proximity to control switches.
