Line 4 is one of several lines of the Tehran Metro. The line is 24.4 km (15.2 mi) with 20 main stations, 3 stations along a domestic airport-serving branch line and a terminal (depôt).
Its section 1, from Ferdowsi Square to Darvazeh Shemiran, opened in April 2008. Section 2 from Darvazeh shemiran to Shohada Square opened in February 2009. Three months later Section 3 from Ferdowsi Square to Engelab Square opened. On July 23, 2012 two more stations were inaugurated, connecting line 4 with line 5.
Currently 20 stations serve Line 4's trunk line, plus two more on the branch line serving the country's most-used Domestic Airport, Mehrabad Airport.
