Abstract
A method and a device for monitoring the presence of at least one guide rail for a guided vehicle, include a first detector located downstream of a wheel. The detector is capable of detecting the presence of the rail and of transmitting a first signal relating to the presence of the rail to a monitoring member. A second detector located upstream of the wheel can be connected in parallel to the first detector and is capable of detecting the presence of the rail. The second detector can communicate a second signal, relating to the presence of the rail, to the monitoring member.
