Other politicians regularly called for the separation, which according to them was essential to open up these populated areas. This was the case for Regional Councillor and President of the STIF's Investment and Contact State-Region Plan Follow-up Commission ("Commission des investissements et du suivi du contrat de plan État-Région"), Alain Amédro, who requested the inclusion of the separation in the contract signed by the Region and Seine-Saint-Denis department. Similarly, Claude Dilain, the mayor of Clichy-sous-Bois (1995–2011), asked that the region finally start planning the branch.
