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.[2]

Currently 19 stations serve Line 4's trunk line, plus two more on the branch line serving the country's most-used Domestic Airport, Mehrabad Airport.[3][4]



The line begins with an interchange station with Line 5 at Eram-e Sabz Station, north of the Tehran-Karaj Freeway near Eram-e Sabz Park in western Tehran.

It heads southward through Ekbatan town then turns east, running along Karaj Makhsus Road, Azadi Square, Azadi Street, and Enghelab Street. This main axis continues for 11.2 km (7.0 mi). The line turns southeast briefly along Rowshandelan Street and until Shohada Square. Then it resumes an eastward course along Piruzi Street. Then it veers north-eastwards and runs along the Doran Expressway until reaching its eastern terminus, Shahid Kolahdooz Station.

Mehrabad Airport ExtensionEdit

The 2.8 km (1.7 mi) branch line starting from Bimeh Station towards Mehrabad International Airport was opened on March 15, 2016. The branch gnerally acts as an independent line, using unique, more luggage-friendly trains; Bimeh Station is an interchange station. The branch has three stations, including Bimeh Station.[5]


North-West expansionEdit

A 5.2 km (3.2 mi) extension north from Eram-e Sabz Station is proposed.[6] The new extension will have 4 stations and run along Shahayegh Boulevard and Jannatabad Boulevard so serve the Jannat Abad neighbourhood in Northeastern Tehran.

Eastern expansionEdit

A 9.3 km (5.8 mi) extension northeast-wards from Shahid Kolahdooz Station is proposed.[6] The proposed section will run elevated along Doran Expressway to Damavand Street. Then it will continue north along Hajar-ebn Ady Street and Estakhr Street. The extension will serve Tehranpars and Qanat Kowsar neighbourhoods.
