Preventing men from entering the special carriage for women in Tehran metro

Since the inception of the subway system in the late 1990s, separate carriages for women have existed, but women were also allowed to use other cars. The potential challenges associated with implementing gender segregation in the subway system include families being separated, individuals becoming disoriented in crowded stations, and family members accidentally disembarking at different stops. Morality police patrols have also recently increased around subway stations.
