Safety device (1) to prevent people and objects falling from a platform (2) down onto the track at, for example a station where the device (1) includes a slab-like protective barrier (4) that extends along the length of the platform (2) at its outer edge. This barrier (4) is formed as an upside down U-shaped profile where at least one of the shanks, the one facing the platform, has a length that is equal to or greater than the intended height of the protective barrier from floor of the platform. The manoeuvring arms (3) are supported to pivot at their respective lower ends at a level below the floor of the platform and at their upper ends are jointed to support the protective barrier (4). In addition, the manoeuvring arms (3) are arranged to pivot from an essentially vertical position to an essentially horizontal or angled position and thereby lower the barrier (4) so that travellers can board or leave the train without hinder when the train has stopped at the platform (2) and to raise the barrier (4) prior to the train beginning its journey again by the manoeuvring arms 3 swinging up to their upraised position. |
