THE board of Paris transport authority Île-de-France Mobility (IdFM) will be asked to approve at its meeting on June 18 the two preferred bidders selected for metro and tram-train operating contracts.

IdFM has chosen Keolis as the preferred bidder for the contract to operate Line 18 of the automated Grand Paris Express network. Line 18 is currently under construction and is due to open between Orly Airport and Versailles Chantiers in three phases from the end of 2026.

The first section to open will be from Massy-Palaiseau to Christ de Saclay. At the end of 2026 Keolis will also take over the operation of Orly Airport station, which is due to open later this month with the extension of Paris metro Line 14 from Olympiades.

The next section of Line 18 to open will be from Orly Airport to Massy-Palaiseau at the end of 2027, followed by Christ de Saclay - Versailles Chantiers at the end of 2030.

RATP Cap Île-de-France is IdFM’s preferred bidder to operate tram-train lines T12 and T13. The 20.4km line T12 entered service in December 2023 between Massy-Palaiseau and Évry-Courcouronnes. Peak service frequency is six trains an hour and the line is expected to carry 35,000 passengers a day.

Phase 1 of line T13 opened in July 2022, running for 18.8km from Saint-Germain-en-Laye to Saint-Cyr. Peak service frequency is also six trains an hour and projected ridership is 16,000 passengers a day.

RATP will also be responsible for operating Phase 2 which is due to enter service around the end of 2028. It will extend line T13 from Saint-Germain-en-Laye to Achères Grand Cormier on RER Line A, which will also be served by the future extension of RER Line E to Mantes-la-Jolie.
