According to Saeed Ohadi, the head of the cultural artistic organization of Tehran municipal council, the marchers and mourners will be able to use free public transport, including the metro and bus service, to get back to Tehran.

Dozens of resting stations (known as Moukab) have beebn set up along the route of the walk, where mourners receive refreshments of various kind.

Every year millions of Iranians travel to the holy cities of Iraq to make an Arbaeen pilgrimage. This year Arbaeen falls on October 30. 

While the province of Karbala has the capacity to host 1.2 million pilgrims, the current number of travelers would impact on plans to provide services to the pilgrims, he added.

Arbaeen, one of the largest religious gatherings in the world, comes 40th day after Ashura, the martyrdom anniversary of the third Shiite Imam, Imam Hussein (peace be upon him).
