Abstract
A device to be fitted to a guided vehicle moving on a track having a guide rail and two side rails parallel to and on each side of the guide rail maintains a trajectory of the vehicle upon derailment. The vehicle includes a guidance unit having guide wheels to be supported on the guide rail. The device includes a bar to be fixed to the guidance unit transverse to the track. The bar has a length L between a distance D mutually separating the side rails minus the width C of the head of the guide rail and the distance D mutually separating side rails, i.e. D−C<L<D. A fixing device fixes the bar to the guidance unit with the bar transversely between and level with the side rails and supported on one of the side rails during a derailment and/or failure of vehicle guidance.
