Cairo's metro network was greatly expanded in the mid-1990s with the building of Line 2 (red), from Shubra Al Khaimah to Cairo University, with an extension to Giza.
It is the first line in history to have a tunnel going under the Nile.[6][7]
The tunnel under the Nile is 8.35 m (27 ft 5 in) in internal diameter and was constructed using two Herenknecht bentonite slurry shield TBMs, which are 9.43 m (30 ft 11 in) in diameter.[6] Extending 21.5 kilometres (13 mi) with 20 stations, it is sometimes called the "Japanese-Built Line".[citation needed] It is mostly in bored tunnel, with two exceptions: a short section at the northern end approaching Shubra El-Kheima which is elevated, and a section just south of this by cut-and-cover. The main difference between Lines 1 and 2 is that Line 1 uses an overhead line while Line 2 uses the third-rail system.[citation needed] The construction of the line was finished in October 2000 and was later extended to El Mounib.[6] The communication for line 2 was provided by Alcatel in 2005.[8]
Total project cost was 761 million euros.
After the 2011 Egyptian revolution, the station "Mubarak" has been renamed and is now called "Al-Shohadaa" (Arabic for "martyrs").
October 1996 Shobra - Mubarak (now:"Al-Shohadaa"), 8 kilometres (5 mi)[9]
