A contract was signed in August 2019 with Bombardier Transportation, Orascom Construction, and Arab Contractors for $4.5 billion to build and operate the two monorail lines. The first will run 54 km from eastern Cairo to the new administrative capital. The second will run 42 km from 6 October City to Giza. As of December 2017, Spokesperson for the Egyptian National Authority for Tunnels (NAT) said that there are plans to extend Line 2 7 kilometers to the north from Shubra Al-Kheima station to end at Qalyub station due to the increasing traffic in north Cairo entrances, He also said that bidding will be held in February 2018 and the winner will be revealed mid 2018. The station will be an at-grade station built parallel to the train railway, bridges will be built to divert traffic from the Metro route. A transportation study of the Greater Cairo region was completed in 1999. It recommended the implementation of a six line system consisting of lines 1, 2 and 3 (existing), and lines 4, 5 and 6. The completed Metro Network would be capable of serving most of the densely populated areas in the Greater Cairo region, which was much in need of a comprehensive mass transit system. The plans include interchange stations between the six metro lines and would also provides interchange facilities with existing main railway stations, the airport, and bus stations. The six planned metro lines aim to meet the transportation demands of the Greater Cairo area up to the year 2032. However, the actual construction and implementation schedule will be restricted by available funding, and it is likely that the timetable will slip. Line 5 would be a half-circular line connecting lines 1-4 in northern Cairo, running from Nasr City in the east, to Port Said Street and Shubra El Kheima in the west. It would have a length of , entirely within bored tunnels. It would intersect Line 1 at "Helmiet el-Zaitoun station", Line 2 at "El-Khalafawy station", Line 3 at "Haroun station", and Line 4 at "Al-Wafaa we al-Amal station". Line 6 would be a north-south line, from Shubra in the north to the Maadi and Helwan districts in the south. It would run from "Ataba Station" through "El Kalaa street" in bored tunnels to "Salah Eldin Citadel Station" (Interchange with "Line 4") and moving on from there to both districts via bored tunnels using the existing route "El-Mahager Railway" as a guide through both Maadi and Helwan.
