Based on its features, Railway has been selected as study and development objectives in many countries. This thesis is mainly focused on the graphic design of overhead line system of Jingzhou station in railway line Hanyi. Firstly, the suspension was selected after the Jingzhou weather condition information was collected and clue material was sift. The load was calculated according to weather condition and clue material. Secondly, the maximum outreach is obtained from the wind shift. Anchoring section is chosen according to specified anchoring section to satisfy tension difference. Then, portal structure was analysed. Finally, on the basis of the above principle, this thesis concentrated on the graphic design of Jingzhou station in Hanyi railway line with CAD, also conducted Check Computation for typical capacity of the pillars. Based on the basic technical principle of highspeed catenary and according to the actual railway condition, this thesis pleted graphic design of overhead line system of Jingzhou station in railway line Hanyi, which could met the basic technological demand of high speed electrified railway.
