I am planning to travel to Beijing at May. I was wondering how to buy a ticket and take a train from Beijing North Station to Badaling Great Wall. I tried to find out this through internet but I just got confused.
Some says that there's exclusive ticket office upstairs for Badaling trains at the North station. One report say that you can use any booth downstairs. Then some says that you can use your ticket (if you manage to get one) on any train during the day and some says that tickets are unique numbered. Some says it's S2-train and some says it's Y-train. I wonder which one is it. Rate also varies from 6 RMB to 25 RMB (one-way). Are platforms and trains signed also in English? Can anyone advise me on these questions?
