Iran: Train schedule and travelling there

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..:)

Maybe this will help you but I have no idea how up-to-date the informations are.

Hi, thanks for your link, but this page I (and we from the german part of the rad-forum) know since several time. The only problem is that here the schedules are for the years 2000 and 2001:-(
If someone finds the actual schedule in english, french, spanish or german it would be great! Could perhaps someone help me who can read farsi?

Thanks and mersi
Steffi
