What should a train do if it receives a message indicating a trackside warning detector is not working?

When a train receives a message indicating that a trackside warning detector is not functioning properly, the appropriate response is to reduce speed to 30 MPH and notify the dispatcher. This approach is crucial for several reasons.

First, the reduction in speed allows the train crew to proceed with greater caution since the failure of the warning detector could mean that hazards on the track are not being identified or communicated. By slowing down, the crew can better react to any potential dangers that may arise ahead, enhancing safety for both the train and everyone on the route.

Second, notifying the dispatcher is essential for maintaining communication and ensuring that appropriate actions can be taken from a central operational perspective. The dispatcher can monitor the situation, possibly rerouting or taking other necessary precautions to mitigate risks associated with the non-functioning detector.

This option integrates both safety and communication protocols essential in train operations, ensuring that trains maintain safe speeds and that dispatch is kept informed to make informed operational decisions.
