What can a train operator do if the indication fails after leaving the terminal while in customer service?

In the context of train operations, if the indication fails after leaving the terminal while in customer service, the correct course of action is to keep the train in service if the conductor has indication in both zones. This option emphasizes the importance of coordination and communication between the train operator and conductor.

When the conductor has the necessary indications, it indicates that they can verify the train’s safety in the specific zones of operation, allowing the train to continue running without unnecessary disruption. This approach ensures that service remains consistent while still adhering to safety protocols, as it allows for proper assessment of the operating environment.

The other choices may not be appropriate in this situation, as returning to the terminal immediately could cause delays and inconvenience to passengers without ensuring safety, while manual overrides may not be advisable without clear indications of safety. Calling the Control Center is also a prudent action, but it may not be required if safety can be maintained based on the conductor's indications. Therefore, maintaining service with verified indications aligns with operational efficiency and safety measures.
