What should a train do upon receiving an incomplete message from a trackside warning detector?

• A. Proceed at normal speed
• B. Reduce speed to 30 MPH until the next detector or inspection
• C. Stop the train immediately
• D. Continue at reduced speed until reaching the next station

Answer: (B)

When a train receives an incomplete message from a trackside warning detector, the appropriate action is to reduce speed to 30 MPH until the next detector or an inspection can be performed. This response ensures safety because an incomplete message may indicate a potential issue with the track or signal that has not been fully identified. By reducing speed, the train can proceed cautiously, allowing for the possibility to identify any problems before proceeding further. This method strikes a balance between maintaining operational efficiency and ensuring the safety of the train and its passengers. Continuing at normal speed, stopping immediately, or proceeding at reduced speed until reaching the next station may not provide the necessary caution and could compromise safety if underlying issues need further assessment. Thus, reducing speed to a specified limit until additional information is received is a precautionary measure commonly implemented in the industry.
