Before use in Bordeaux, APS was tested and proved viable on a short section of reserved-track tramway in the French city of Marseilles.

Nevertheless, Bordeaux has experienced problems, with APS being so temperamental that, at one stage, the Mayor issued an ultimatum that if reliability could not be guaranteed, it would have to be replaced with overhead wires.

Although things have improved, in October 2005 it was announced that 1 km of APS tramway was to be converted to overhead wires.
