M1 (Fahedajellal Metro)

The M1 Emireis Bridge - Borkent is a rapid transit line in Fahedajellal, the capital city of Ardistan. It opened in 2001, between Emireis Bridge and Maribar, as the first metro line in the country.

Extension work began in 2009 towards Bin Hafez International Airport, in time for the airport's opening in 2013. Delays in the construction work means that the line currently terminates at Borkent, and three stations towards the airport remain under construction due to open at the end of 2014.
