Research conclusions: Through making analyses and doing research on the concrete influencing factors, the final plain layout of Suide Station is decided as follows; Taiyuan-Zhongwei and BaoTou-Xi an railway lines enter into Suide Station separately according to the direction and in the station, Baotou-Xi'an Railway Line is outside Taiyuan- Zhongwei Railway Line. The problems of exchanging traffic flows from two railway lines in Suide Station is solved well with this layout scheme , such as exchanging traffic flows from Taiyuan to Baotou direction and from Zhongwei to Xi an. At the same time, the design is more standardized by adopting this scheme.
