Which term describes the indication that a track is occupied even though no train is present?

• A. Derail
• B. Energize
• C. Emergency
• D. False Occupancy

Answer: (D)

False occupancy is the term used when the signaling system shows a track section as occupied even though no train is in the block. This happens when track circuits or detectors misread faults or interference as the presence of a train. In practice, operators must treat that block as occupied and have maintenance verify clearance, since the indication isn’t reliable. It’s exactly describing a track being shown as occupied without a train actually being present. The other terms refer to different concepts: derail is about causing a train to leave the rails, energize means applying traction power, and emergency is a safety stop action.
