The southwestern branch of Tehran Metro Line 1 from Shahed to Namayeshgah-e Shahr-e Aftab was rebranded as Line 8 when an extension to Imam Khomeini International Airport opened on August 7.
This is the second metro link to the capital’s airports, with Line 4 already serving Mehrabad airport.
The extension to Imam Khomeini International Airport runs at ground level, paralleling the alignment of the Tehran – Qom motorway.
A further extension to the satellite town of Parand is under construction. This will be Tehran Metro’s first ‘express’ line, with a maximum operating speed of 120 km/h.
