The work is part NAT's project to upgrade the line, which was built in 1989 and is the backbone of the Greater Cairo underground metro network. The line ridership is two million passengers per day.
Alstom will provide the computer-based interlocking system to guarantee the safety of the trains while moving in the depot. It will also supply the supervisory control and data acquisition (SCADA) system for traffic and traction, and telecoms equipment.
The latest award follows two contracts awarded this year by NAT to Alstom for the supply of signalling and infrastructure for phases 3 and 4A of line 3 of the Cairo metro.
