                                It is not very hard for transfer. There is a railway station right at the airport called Zhongchan Airport Station. From there, you can reach both stations by rail directly. Then you can change to another ride to your final destination, but surely, you need at least 30min or 60min between for a transfer process. If you will choose to take a high speed rail, you will need to go to Lanzhou West Station, if by normal rides, they you will use the main station.
