The Iranian capital is planning a major expansion of its subway system, with Mayor Alireza Zakani saying the new development phase would elevate Tehran’s metro to the fifth‑largest globally, considering the total length of the network.
Zakani said on Tuesday that Tehran intends to add 36 kilometers of new lines and 21 stations over the next five years.
According to him, the expansion would move the system from its current position, which he placed at 16th, to fifth among the world’s largest metro networks.
“This is a great achievement and honor for the country,” he said while inaugurating a new station in a densely populated district of eastern Tehran.
Zakani added that two more stations will open before the end of the Iranian calendar year in late March, bringing the length of the network to roughly 320 kilometers with 164 stations.
He said the municipality is preparing Lines 8, 9, 10 and 11 for construction, noting that contracts have been awarded for work that will extend the network by an additional 171 kilometers.
Zakani also announced that a contract with Chinese suppliers for 1,184 subway cars has been finalized, with the first batch expected to arrive after completing customs procedures.
He added that a third batch of domestically produced metro cars will be delivered by March, and that monthly additions will rise to more than 20 cars next summer.
The mayor said a new financing scheme is being developed for metro‑related projects in Tehran to support contractors and accelerate construction timelines.
