Tehran Metro Line 1, coloured red on system maps runs north-south and is 36.6 kilometers (22.7 mi) of which 14.9 km (9.3 mi) is underground (from Tajrish station to Shush Station) and the rest at grade (at surface level). The number of stations along this line is 29 of which 22 stations are underground and 7 above. As of 2005, the line's total capacity is 650,000 passengers per day and trains make a scheduled stop of 20 seconds per station. The trains are made up of seven wagons, giving a nominal capacity of 1,300 seated and standing passengers. The maximum speed of the trains is 80 km/h (50 mph) per hour in practice tempered to an average 45 km/h (28 mph) due to station stops.

Line 1 runs mostly north-south, and the southern terminus has interchange platforms for its extension sometimes termed Metro Line 8, to Imam Khomeini International Airport completed in August 2017.^[2] A 4.1 kilometers (2.5 mi), three-station extension of the line from Mirdamad station to Qolhak opened on May 20, 2009; a 4 kilometers (2.5 mi), four-stations second phase from Qolhak to Tajrish Square was completed in 2012.^[3] Construction was to be completed by March 2007 but faced major issues due to large boulders and rock bed in part of the tunnels as well as water ingress/drainage issues. It also faced major financing issues as the government refused to release funds earmarked for the project to the municipality.
