Excuse me , can you help me figure out how to get to the Wudaokou subway station from here ?   Sure ... first you're going to have to buy a ticket to ride on the subway . The Wudaokou station is on the lightrail , so you'll have to transfer . Be sure you buy a combination ticket for the regular subway and the lightrail . It should cost you 5 yuan .   An after I buy the ticket , where should I go ?   You can take the red line train from here , but you'll have to transfer to the blue line at Fuxingmen transfer station . After you transfer , take the blue line that is heading north towards Fuchengmen .   So I transfer from red to blue , then how long do I ride the blue ?   You'll take the blue line until you reach Xizhimen . That's a big station , so there will likely be a lot of people getting off at that stop . You can transfer to the lightrail there , you'll have to exit the subway and present the unused portion of your combination ticket to the Ticketmaster , they'll give you a new ticket to use on the lightrail system .
