Alstom, which is leading a consortium with Thales, will install its Urbalis signalling system as well as signalling equipment for stations, an Iconis train control centre, and point machines. Alstom together with Colas Rail, Orascom and Arabco will supply electro-mechanical equipment comprising substations to feed the third-rail electrification, ventilation, escalators and lifts. The signalling contract is worth €85m and the infrastructure contract €102m.

Phase 3, which is currently under construction and due to be completed in 2022, involves extending Line 3 by 17.7km from Attaba west to Kit Kat Square where the line will split. The northern branch will run via Embaba to Rod El-Farag, while the southern section will serve Cairo University. The extension will add 15 stations to the network and will increase traffic on Line 3 to more than 1.5 million passengers a year.
