a first rail system designed for the movement or guidance of a vehicle or any other moveable device, and including:
at least one first rail having a rail head whose upper surface is approximately flush with the road surface, a first lateral face and a second lateral face opposite the first lateral face; andat least one spacing feature designed to establish a passage space for the relief structures of a guide at the least on one side of the first lateral face of the rail head; a second rail system for the guidance of a vehicle and including at least one guide rail, which guide rail:
has a rail head with an upper face approximately flush with the road surface and crossing the first rail;is interrupted at the crossing with the first rail to form two portions, having respectively a first end and a second end extending the first end; at least one extensible part integrated into at least the first or the second portion; at least one mechanism designed for lengthwise extension and contraction of the extensible part, defining a contracted position in which the first end is moved away from first rail to allow the passage of a vehicle or any other movable device over the first rail; and an extended position in which the first end is moved closer to first rail to guide a vehicle along the guide rail. |
