If both the train operator and conductor lose indication while moving the train, what must the train operator do first?

When the train operator and conductor lose indication while the train is in motion, the primary responsibility is to ensure the safety of the train and its passengers. Stopping the train is the first critical step to prevent any potential hazards that may arise from operating the train without clear indications. This action allows the operator to reassess the situation safely.

Once the train is stopped, calling the Control Center is essential because they have the authority and resources to provide guidance and assistance in resolving the loss of indication. The Control Center can offer real-time information, instruct actions, or coordinate emergency responses if needed.

Taking immediate action to stop the train before contacting the Control Center emphasizes the importance of prioritizing safety over continuation of travel, especially in uncertain conditions. This sequence of actions aligns with safety protocols within train operations.
