The invention concerns a rail crossing device designed for crossing a first rail embedded in a road surface with a guide rail, embedded in the road surface. It comprises at least one extensible portion provided in the guide rail and at least one mechanism designed for lengthwise extension and contraction of the extensible portion. This mechanism is designed to extend and contract the extensible portion in a lengthwise direction, defining a contracted position in which one end of the guide rail is separated from the first rail to allow a vehicle or any other movable device to travel along this rail, and an extended position in which said end of the guide rail is moved towards the first rail in order to guide a vehicle onto the guide rail. |
