Abstract Research purposes ： The railway optimization is developing towards collaborative optimization of line - station，which is based on automatic station locating. Traditional research is lack of systematic consideration about complex constraints among the alignment - stations - environment - structures，which mostly focus on how to select the best station location in the case of the station location alternatives. This paper proposes a method of automatic station locatingunder complex constraint conditions which can divide station locating into station center selection and site direction selection and can quickly and automatically search economic station schemes satisfying the intricate constraint conditions，to provide a reference for designers.
Research conclusions ： ( 1 ) Integrated geographic infomation model based on the system of spatial grid index was established to provide data foundation for station locating. (2 ) Calculation efficiency of the method was increased by divided thought of station center and site direction. (3) A model for calculating the station comprehensive cost was raised considering the cost of land，quantity of earcth work，distance to economic point，deviation to expected route，providing the basis for evaluating the perfomance of stations. (4) A railway in southwest mountain area was analyzed to verify the effectiveness of this method，and the station schemes satisfying the intricate constraint conditions can be quick?ly figured out，which lays the foundation for line - station collaborative optimization.

Key words： intricate constraints automatic station locating comprehensive cost
