If you are approaching a train on the adjacent track that sets off a dragging equipment detector, your train must immediately:

• A. Stop the train immediately until confirmed safe to pass by crew or RTC.
• B. Speed up to clear the detectors.
• C. Ignore the detector and continue.
• D. Sound the horn and proceed.

Answer: (A)

When a dragging equipment detector on the adjacent track signals, you must stop immediately because a loose or dragging item can cause a derailment or damage if the train keeps moving. The detector flag indicates a potential hazard that you cannot safely assess or clear while in motion. You then wait for explicit clearance from the crew or the Rail Traffic Controller to pass, after they verify that nothing is dragging and it’s safe to proceed. Do not try to fix it by speeding up, ignore it, or rely on a horn; those actions do not address the risk and are not permitted.
