Cab Signal is defined as?

• A. A fixed signal displayed at the entrance of a block.
• B. A signal located in the engine control compartment and which indicates track occupancy or condition. The cab signal is used in conjunction with interlocking signals and with or in lieu of block signals.
• C. A blue signal.
• D. A bulletin order.

Answer: (B)

A cab signal is a signal displayed inside the locomotive cab that communicates the status of the track ahead to the engineer—such as whether the next block is occupied and what speed restrictions apply. This information supplements interlocking signals and can even replace trackside block signals where a cab signaling system is in place. It’s distinct from a fixed signal at the entrance of a block, isn’t simply a blue indicator, and is not a bulletin order. The cab signal provides real-time route status directly in the cab to help manage train movements safely.
