Siemens will supply its Trainguard MT CBTC automatic train control system as well as Airlink, a track-to-train continuous-data radio transmission system, and Digiloc train location. The CBTC on Line 1 uses moving block with an absolute stopping distance and incorporates automatic train operation (ATO). The contract also includes staff training.

Commissioning of the four-station southern extension from Hai El Badr to El Harrach-Centre is scheduled for mid-2015.

Siemens won the original turnkey contract to construct the initial phase of Line 1 in 2006, and the line opened in 2011.
