Chongqing to Zunyi

Hi, I'm currently in Shanghai and will fly into Chongqing Jiangbei International Airport. Once there, I would like to book a train ticket to Zunyi, Guizhou. There seems to be a few railway stations in Chongqing, should I go to the Chongqing North station? (It looks like Chongqing North station is the closet to the Chongqing airport, about twenty minutes.) Is this right? Please advise, thanks!
