Abstract：Research purposes:From the study on the planning of the inter － city railway network in Guanzhong of Shanxi Province，it can be seen that the Guanzhong Urban agglomeration is the core region of the Guanzhong － Tianshui Economic Region，and construction of the inter － city railway network is the major action to promote the balanced development among different regions and form an important stragetic highland for the west development． Also this railway network has the significant realistic effect and profound historic sense for giving play to its proper and leading effect，promoting the economic revitalization of the North － West China，and pushing foreward the sustainable development．After the establishment of the Guanzhong － Tianshui Economic Region，the radiating and driving play of the Guanzhong Urban Agglomeration with Xi'an City as center will be further strengthened．
Research conclusions:Based on studying the overall development plan，the space distribution，industry layout plan and passenger flow distribution of the Guanzhong Urban Agglomeration，the skeleton of network was defined．Finally，the circular radiative network structure of a " V" shape main frame was recommanded with Baoji － Xi'an － Weinan as main axis and Xi'an as the center．
