Abstract：Guangtong lies in Chuxiong of Yunnan Province,has special geographical location,is one of the necessary stronghold of Chengdu-Kunming Railway,has a lot of paths which should be linked up. But the surrounding terrain conditions are difficult, the level height difference is big, the setting conditions of contract line are adverse. So it is necessary to study to guide the engineering design and provide a reference for the similar project.Research conclusions:(1) For the area with new line and existing line, should first study the functions and their respective division, as the basis of general drawing program research. (2) Use of annular contact line, can greatly shorten the contact line length, save the engineering investment, but has a certain influence to the capacity and operation of the station, which should be seriously considered before select and use. (3)Area programs should take full account of the introduction of existing facilities and existing lines,enhance the social and economic benefits.(4)Area programs should be in accordance with the general plan of economic, practical principles unified planning, related projects should be timely implemented according to the traffic growth situation, to reduce the initial one-time investment. (5) The research results can be applied to area general drawing program which determines similar double "T" shaped structure.
