The story
Construction of the meter gauge line began in 1890 followed by a partial opening in 1892. Construction ended on 3 July 1911 and conceded to Sud-France. Lines from Nice stretched to Grasse, Puget-Théniers (opened in 1892), Digne (opened in 1911) and Annot.
After World War II, the line to Meyrargues closed and almost took the entire network with it. The Chemins de Fer de Provence closed the Gare du Sud in December 1991 and moved its terminating services to Nice CP.
On 5 November 1994 flooding of the river Var cut the line in several places and forced upon the line a total closure. A new bridge at Gueydan was built and the reopening of the line occurred on 12 April 1996.
The remaining line is 151 kilometres (94 mi) long. It comprises 27 tunnels, including the 3,457-metre-long (11,342 ft) Tunnel de la Colle Saint-Michel. The exit of the tunnel, Dignes-side, is at an elevation of 1,023 metres (3,356 ft).
The railway's terminus in Nice was until 1991 at Gare du Sud and since then Gare de Nice CP. The station is the terminus of a 1,000 mm (3 ft 3+3⁄8 in) (metre gauge) railway from Digne-les-Bains.
In Digne there was also a former railway line to Grenoble (standard gauge) operated by the SNCF. The SNCF had its own station building opposite the CP station.
In Digne the former station of the CP is no longer used. The narrow gauge track and the ticket service are moved to the former SNCF station building.
