The project of adding the branch line to Montfermeil also required considerable works at the Bondy terminus and the Gargan station. The platforms of the Bondy terminus were lengthened and reorganized to assign a platform dedicated for arrivals and another dedicated for departures, allowing for 3 minute intervals between both departures and arrivals. The installation of switches to the branch required that Gargan station be moved entirely 90m further southwards down the line. The conversion of traction to 750v takes place gradually about 2 km along the branch from Gargan because several hundred meters are required for the lowering of the pantograph and the conduction of the current.
