Research conclusions:The Baicheng railway is planed as a one － station form with arrangement in a horizontal line for the passenger and freight traffic ．The Baicheng Station is a passenger station and also a technical operation station to deal with the passenger and freight transport in the region． The Changchun － Baicheng － Wulanhaote rapid railway should be lead into the Baicheng station by the direction orientation，and the Baicheng Station should be arranged in a horizontal line for the passenger and freight traffic． The overall layout of the small railway region is not suitably arranged as the separate lines for passenger and freight traffic，which is adopted to the large and medium － sized railway terminal．The one － station type arrangement or cross － type junction arrangement or in － line arrangement should be adopted to the small railway region． This can set an example for research and design of the overall layout of the railway terminal(region) ，especially of the small railway region．
