Which railway station?! I am confused!

I am in Toshkent right now and I’ll take a train from Toshkent to Samarkand in a couple of days. My train ticket says « departure 8:37, train line 710 A », but it seems there are several railway stations in Toshkent. Which station should I go to for this train? My ticket says « TOSHKENT-SH » but I can’t figure out whether it’s the southern railway station or the northern railway station. Thank you very much if you can help me to clarify that, I don’t want to miss my train!
