Hello everyone here and salam!

I will probably go to Iran this summer for four weeks - if I get my visa;). I am looking for cities to go and visit. For this I'll take busses and trains because I don't want to cycle in the middle of summer.
I am looking for the homepage of the Iranian Railway Association to see the schedules. Until now I didn't find the right page. Sometimes pages are just in Farsi and so I don't understand them!
Can someone help me and tell me the actuel homepage to see the train schedules? Thanks a lot, mersi!
Sure that I am also interested in all other things related to travelling in Iran, cities to go and not to go..:)
