The track is the marked entrance to a private property, one on the North side, one to the South. They are not connected as the map seem to suggest. There used to be a track that followed the borders between La Commune de St Pompon y La Commune de Campagnac Les Quercy. Landslides and narrow pass between buildings encouraged the Commune to reopen the track further East an it is now the current public road as marked in your map. The land occupied by the old track was sold by the commune and bought as Cadastre registered land  by the old proprietaries. Now is part of the farm. We will be very grateful if you could update your maps because, as they currently show, encourage vehicles into the farm’s private grounds at road speeds endangering people and animals.
The current owners.
