What must be done if track bridges or other structures are found to be dangerous?

When track bridges or other structures are identified as dangerous, it is crucial to provide proper protection and inform the Train Dispatcher. This approach ensures that the situation is managed appropriately to prevent accidents and maintain safety on the tracks.

By providing proper protection, it could involve signaling to oncoming trains or establishing physical barriers to prevent access to the dangerous area. Reporting the issue to the Train Dispatcher is essential for initiating a coordinated response, which could include rerouting trains or conducting emergency repairs.

This process aligns with safety protocols that emphasize proactive measures in response to hazardous conditions, ensuring the safety of both railway personnel and the traveling public. The other options do not prioritize safety or proactive communication in the way that providing protection and notifying the Train Dispatcher does.
