Which device is considered an audible warning device on rail infrastructure?

• A. Display board
• B. A device that records safety incidents
• C. A device such as a whistle, siren, horn or hooter used to give warning
• D. A track circuit monitor

Answer: (C)

Audible warning devices are the sound-making tools used to alert people and railway staff of train movement or hazards. A device such as a whistle, siren, horn or hooter produces a loud sound designed to grab attention, especially in busy or noisy environments or at crossings. This direct sound warning is what helps people react quickly to approaching trains or unsafe conditions. The other options don’t provide an audible alert: a display board communicates information visually; a device that records safety incidents stores data for later review; a track circuit monitor checks the status of track circuits to detect trains or faults. Since the goal is to warn by sound, the device that emits an audible alert is the correct choice.
