Abstract：Research purposes: In the jointing area of independent engineering coordinate system of hish—speed railway，the inappropriateness of the coordinate system and track design causes the problem that the central line of track is not be linked up smoothly．Through the comparative analysis，this paper analyzes its reason and offers a solution，which has a directive sense to design of the coordinate system and track．
Research conclusions:Through the analysis of the problem in the jointing area of coordinate system，the following points can be concluded：The projection distortion difference between the adjacent coordinate systems should be controlled reasonably in designing the coordinate system．The control points after transferring the central meridian of coordinate system should be chosen correctly for the design of track．The same control points in different coordinate systems should be transferred by changing the central meridian of coordinate systems．
