What is the platform edge safety line?

• A. A painted or marked line on the platform indicating the safe distance from the track when trains are present.
• B. A barrier wall at the platform edge designed to stop passengers from approaching the track.
• C. A visual indicator showing train arrival times on the platform wall.
• D. A tactile surface at the edge that signals where to stand by feel.

Answer: (A)

The platform edge safety line is a painted or marked line on the platform indicating the safe distance from the track when trains are present. It provides a clear visual cue for passengers to stand behind it to avoid getting too close to moving trains or the edge. It’s not a barrier wall that physically blocks access, nor a display of train arrival times, and it isn’t a tactile cue you feel with your feet—those functions are served by barriers, timetable displays, or tactile warning features, respectively.
