Zhengding Airport is the train station from shijiazhuang airport to beijing?

Well yes, it is at Zhengding Airport that you can take a bullet train to Beijing. As I know, over ten trains are in service for this journey and they will lead to Beijing West Station within around 1.5h. You can search for its google address, but I can just tell you it takes around 10min to the station from the airport by shuttle bus. You need to pay CNY 111.5 for a second-class; CNY 179.5 for a first-class; CNY 353.5 for a business class. :)
