according to ali-baba its 8 hours and 10 minutes and the price is 210000 toman (around 4$)how long is the Sanandaj-Tehran train journey, how fast do the trains travel and what is the cost of the fare?
I guess 5-7 hours, not very fast, and very cheap
but the road has one problem the train only available on Fridays and Tuesdays . the route don't work on other days . hope at least cargo train works on other days
