Which statement is true for operation in equipped territory after a departure test?

• A. The cab signal should conform to each fixed signal within 6 seconds after entering a block.
• B. The cab signal may ignore fixed signals if signaling is functioning.
• C. The fixed signal governs at all times.
• D. The engineer must rely on the cab signal only.

Answer: (A)

In equipped territory, the cab signal system is the immediate source of signal information for the engineer, but the fixed (wayside) signals still hold authority. After a departure test, the important requirement is that the cab signal must reflect or conform to the fixed signal for each block within six seconds after entering that block. This rapid alignment ensures the engineer isn’t acting on outdated or conflicting information and confirms proper signaling is being followed as you move from one block to the next. The six-second window provides a concrete cadence to verify that the cab display and the fixed signal are in agreement before proceeding. The other statements imply ignoring or bypassing fixed signals or relying solely on one system, which would undermine the built-in redundancy and safety that equipped territory is meant to provide.
