What does the Blocked Device Removed (BDR) code serve to do?

• A. Transmit weather information to crews
• B. Assign track sections to trains
• C. Send a unique number to prevent fouling a track
• D. Control the speed of approaching trains

Answer: (C)

The Blocked Device Removed (BDR) code is primarily used to send a unique number that helps manage and maintain safety on the tracks by preventing fouling. When the BDR code is issued, it indicates that a certain section of track has been cleared or defined in a manner that ensures that no other train or apparatus will inadvertently interfere with operations in that area. By assigning this unique number, locomotive engineers can be assured that they are operating within a safe zone and that track conditions are adequately monitored, ensuring accountability and security in train movements. The other choices do not accurately represent the BDR's function. Transmitting weather information or controlling train speeds involves different systems and protocols that are not related to the BDR code. Additionally, while assigning track sections pertains to overall train operations, it does not specifically address the unique identification aspect crucial to preventing track fouling that the BDR focuses on.
