In non-signaled or double-track territory, a train may report clear of the limits after passing a location only when which condition is known?

• A. It is known the train is complete
• B. The marker is verified on the rear car
• C. The crew has completed the job briefing
• D. The dispatcher confirms track warrant limits.

Answer: (A)

In non-signaled or double-track territory, you can report clear of the limits only when you have positive knowledge that the entire train has passed the location. This is because there are no fixed signals to confirm the tail end’s position, so clearance must be based on a definite indication that the train is complete and fully clear of the block.

Verifying a rear marker or relying on a crew’s job briefing doesn’t prove that the whole train has cleared the limits, and a dispatcher confirming the track warrant doesn’t change the physical fact that the tail end may still be in the block. Therefore, the safe criterion is knowing that the train is complete.
