The Tehran Metro is a rapid transit system serving Tehran, the capital of Iran. The system consists of four operational metro lines (and a fifth commuter rail line), with construction begun on a further two lines in 2007.
The Tehran Metro carries more than 3 million passengers a day. In 2014, 815 million trips were made on Tehran Metro. As of 2015, the total system was 170 kilometers (110 mi) long, 127 kilometers (79 mi) of which it metro-grade rail. It is planned to have a length of 430 kilometers (270 mi) with 9 lines once all construction is complete by 2020.
On all days of the week, the Metro service runs from approximately 05:30 to 23:00.
The line uses standard gauge and is partly underground. Ticket price is 10000 IRR for each journey (about USD 0.3), regardless of the distance traveled, but using prepaid tickets costs much less. Seniors may travel for free on the metro. On all Tehran metro trains the first, the second, and the last carriages are reserved for women who do not wish to ride with men in the same car. Women can still ride other cars freely.
