Infrastructure manager SNCF Network closed the line in December 2016 to carry out the works, which included track improvements and the construction of a passing loop at Le Bosquet station. This has enabled frequencies to be doubled to half-hourly (38 trains per day).

The project included the extension of platforms to 220m to accommodate new Bombardier Régio 2N double-deck EMUs, which are now being used on services to Grasse.
