Abstract：Research purposes: The speed D—value of train through the CurVe at both sides of station is rather big．The track super elevation innuences the comfortableness of passenger train and also directly innuences the selection of curve radius and the length of the transition curves．Using big radius curves can improve the comfortableness of passenger train，but it needs to cover more land．However，the most stations locke in the urban densely populated area．Using small radius curves can much reduce the work of moving people out．Through the analyses of the Curve radius，the transition curves and the super elevation setting，this paper sives some suggestions to selection of the curve radius value and the length of the transition curves at both sides of station．
Research conclusions: The curve radius at both sides of the station of passenger dedicated line should be chosen with consideration of the terrain conditions and calculated on the base of the minimum train speed．If the terrain conditions permit．the 1 1 000—12 000 m curve radius and the max．transition curve stipulated in the code should be adopted．For considering the further speed—raise in future，it is advised the transition curve length should extend 30 m，when adopting 1 1 000～12 000 m curve radius．
