Tehran’s Metro is one of the busiest metros in the Middle East. The system is owned and operated by Tehran Urban and Suburban Railway. It consists of 6 operational metro lines (and an additional commuter rail line)
As of 2019, the total system was 229 kilometers (142 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 9 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 1000 Iranian Toman for each journey (about US$0.25), 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 who do not wish to ride with men in the same car. Women can still ride other cars freely.
