The SAFEGE monorail system was developed in France. The design was headed by Lucien Chadenson .

The design of the system entails a monorail suspended from a box-like track, with an opening in the bottom. The rubber wheels of the train run inside the track.

Unlike previous suspended monorails like the Schwebebahn in Wuppertal, Germany, the tracks are not exposed to inclimate weather, and do not need any cleaning or ice-removal systems. This advantage enables them to run in cities where ice and other conditions would impair the reliablity of the system.

Safege Monorails in the World

• There are two SAFEGE-style monorails in Japan. One in Chiba City and the other in Shonan.
• The test track built in France by SAFEGE in 1958, is featured prominently in the 1966 movie adaptation of Fahrenheit 451, directed by François Truffaut. However, the track has been dismantled since then.
