Bièvre bus network

Former network

On January 2, 2006, the network was significantly expanded with the creation of lines 8, 9 and 12.

On May 26, 2007, the network is undergoing an initial restructuring with a simplification of the line 8 and the abandonment of service to Sceaux and Bourg-la-Reine by the line 12.

On August 26, 2013, the line 1 is diverted through Wissous and the district Saint-Éloi.

Due to the opening up of the competition of public transport in Île-de-France, Le Paladin changed to Bièvre on August 1, 2022, corresponding to public service delegation number 37 established by Île-de-France Mobilités. A call for tenders was therefore launched by the organizing authority in order to designate a company that will succeed the operation of Transdev Bièvre Bus Mobilités for a period of eight years. It was finally RATP Cap Île-de-France, via its subsidiary RD Bièvre, which was designated during the board of directors on October 12, 2021.^[1]

At the time of its opening to competition, the network consisted of lines 1, 2, 4, 8, 9, 12, 15 and 18 of the former bus network, Le Paladin. Lines 3, 6, 7, 11, 14, 16 and 17 are integrated into the Vallée Sud Bus network.

From June 26, 2023, the lines are renamed according to a new numbering system implemented by Île-de-France Mobilités. Lines 4 and 12 merged to become line 412.^[2] In addition, some lines see their lines modified.^[3]

From June 24, 2023. RATP Cap Bièvre also operates Tramway line 10.^[4]

Network renaming

As of June 26, 2023, the Bièvre network is one of the first to apply the new principle of unique regional numbering planned by Île-de-France Mobilités, removing duplicates concurrently with the commissioning of the Île-de-France tramway line 10.^[5] The correspondence between old and new numbers is as follows:^[5]
