<p>Disclosed herein is a train platform safety device. The train platform safety device is installed at a position corresponding to a safety line on a subway or railway platform and is configured such that wire ropes (200) are moved upwards or downwards depending on conditions in which a train approaches or departs from the platform, thus preventing a passenger from intentionally or unintentionally falling onto the train track. Particularly, the distances that the wire ropes (200) move upwards or downwards are determined by rotating a rotating unit (140) including rotating members having different diameters, whereby the wire ropes (200) overlap each other or spread from each other. In this way, the wire ropes (200) allow or block access of passengers depending on conditions in which a train approaches or departs from the platform, thus fundamentally preventing a safety accident.
