texts: So I transfer from red to blue , then how long do I ride the blue ?
labels: 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 .
