Viaducts for the line were built to cross the rivers Siagne, Loup and Var.
The line was connected to Nice at the city's neo-classical terminus station, the Gare du Sud.
Destruction of viaducts during WWII closed the section of the line between Nice and Tanneron and the rest was shut in 1950 as it was uneconomic.
