The Tehran Metro (Persian: مترو تهران, romanized: Metro-ye Tehrān) is a rapid transit system serving Tehran, the capital of Iran. It is the largest metro system in the Middle East. The system is owned and operated by Tehran Urban and Suburban Railway. It consists of six operational metro lines (and an additional commuter rail line), with construction under way on three lines including west extension of line 4, line 6 and north and east extension line 7. The Tehran Metro carries more than 3 million passengers a day. In 2018, 820 million trips were made on Tehran Metro. As of 2020[update], the total system was 253.7 kilometers (157.6 mi) long, 186 kilometers (116 mi) of which is metro-grade rail. It is planned to have a length of 430 kilometers (270 mi) with nine lines once all construction is complete by 2025. On all days of the week, the Metro service runs from approximately 05:30 to 23:00. The line uses standard gauge and is mostly underground. Ticket price is 1,500 Iranian Toman for each journey (about US$0.06), 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 and half of the second carriages from each end are reserved for women. Women can still ride other cars freely. From Wikipedia
