What action is required after a train comes to a stop due to an emergency?

After a train comes to a stop due to an emergency, initiating an emergency radio transmission is essential to ensure timely communication regarding the train's status and the nature of the emergency. This action allows for coordination with the appropriate authorities and emergency response teams to assess the situation and provide assistance if necessary.

By sending out a radio transmission, the crew can inform dispatchers and other trains operating in the vicinity, thereby enhancing safety measures and minimizing the potential for further incidents. This transmission also serves as a critical step in following the required protocols for emergency situations within the NORAC guidelines, ensuring that all involved parties are aware of the situation and can respond accordingly.

Other options, while related to safety and operational procedures, occur at different stages or may not be necessary immediately following an emergency stop. For instance, securing the area or conducting an inspection may come after communication has been established, and fueling procedures are not related to the immediate response required for an emergency situation.
