[1] The public transport authority, the Regional Council, runs 800 trains a day, especially near Avignon, Marseille, Toulon and Nice.

Unlike most other regions in France, the Provence-Alpes-Côte d'Azur separates their trains into two services: This separation is done due to the presence of big metropolises on the coast (Marseille, Toulon and Nice) and a very rural hinterland (French Alps).

The suburban trains from Marseille also continue onto Avignon, 100 kilometres (62 mi) away.

The rail network as of May 2022:[2][3] branch line: Grasse – Mouans-Sartoux – Ranguin – La Frayère – Le Bosquet – Cannes Rail service not part of the TER Provence-Alpes-Côte d'Azur network: With the building of the new LGV Provence-Alpes-Côte d'Azur line between Marseille and Monaco expected by 2030, regional traffic may grow.

This will be achieved through the introduction of a new high speed train calling every hour at Marseille Provence Airport, the construction of a new underground train station in downtown Marseille, a new high speed stop in Marseille's Eastern Districts, and the enlargement of Toulon, Nice Côte d'Azur Airport and Nice Ville train stations.
