What should the train operator do when approaching a home signal displaying stop and sees a man with a white lantern?

When a train operator approaches a home signal displaying a stop indication and observes a man with a white lantern, the presence of the white lantern typically signifies a specific instruction or message from a ground crew member. This signal is a form of communication indicating that the operator should seek further clarification or instruction regarding the stop signal.

In this context, it is crucial for the operator to call the Control Center Desk Superintendent to understand the situation better. The operator must ensure safety and adhere to operational protocols, which often include verification of the signal's status and any additional instructions that may be necessary before proceeding. Engaging with the Control Center is essential to coordinate any required actions and to prevent any potential safety issues.

The other options do not emphasize the appropriate response required in this situation. For instance, proceeding with normal speed would disregard the stop indication and could lead to unsafe conditions. Waiting for further instructions may not be suitable without first communicating with the Control Center or ground personnel, and ignoring the signal entirely is unsafe and against operational rules. Therefore, reaching out to the Control Center ensures that all actions taken are aligned with safety protocols and operational guidelines.
