What should a train do after receiving notification of an activation failure?

When a train receives notification of an activation failure, it is essential to prioritize safety and ensure that appropriate measures are taken to mitigate any potential risks on the tracks. Stopping the train allows crew members to assess the situation and determine the best course of action. Additionally, ensuring that on-ground warning is provided helps alert other trains and personnel to the failure, minimizing the chance of an accident or incident.

Proceeding at normal speed could lead to dangerous situations, particularly in areas where the activation failure could impact safety systems, such as signals or crossing gates. Continuing with caution without stopping may not provide sufficient security, especially if the activation failure requires immediate intervention or monitoring. Notifying the dispatcher without stopping also lacks the necessary immediate action to ensure safety on the ground. Thus, stopping and ensuring on-ground warning is the appropriate response to effectively address the activation failure scenario.
