BRD associated Cab code?

BRD associated Cab code?

• A. 75 code
• B. 60 code
• C. 90 code
• D. 120 code (track circuit)

Answer: (D)

In cab signaling, each signaling function or device in the block is tied to a specific cab code that tells the locomotive cab how to read the information from the wayside equipment. The BRD in this context is associated with the track circuit, which uses the 120 code to convey occupancy and related data to the cab. That’s why the correct association is 120 code (track circuit). The other numbers correspond to different signaling functions or older systems, which do not represent the BRD’s track-circuit relationship.
