The metro has been built as a turnkey project by a consortium led by Siemens and including Vinci Construction Grands Projets, France, and CAF, Spain. The line will be operated by RATP El Djazaïr, a subsidiary of Paris Transport Authority.
Siemens was responsible for installing track, electrification and power supply, fare collection equipment and the entire signalling and train control system. The latter comprised its Trainguard MT communications-base train control (CBTC) system, Airlink radio system and Digiloc train location system.
Vinci was responsible for the civil works, escalators, tunnel and station ventilation, the control centre and maintenance depot, while CAF supplied a fleet of 14 six-car trains.
A 3.5km extension to Line 1 and two more lines are planned.
