ABSTRACT:
In a vehicle guidance system, a circular-section guidance rail is embraced y a detector on a vehicle. At a fork, where the rail progressively broadens prior to dividing, the rail height is reduced so that a detector, when tilted to select one branch of the fork, has its lowered side between the rail and a side wall of a channel in which the rail is mounted and its raised side riding over the broadened rail.
