Abstract：Research purposes: The plane design standard for railway line decides the train running speed and the comfortable level，and affects the construction cost．By analyzing and researching the train operating plan and the V—S curve，the scientific and reasonable plane design standard for the railway line is obtained in order to meet the design requirements for the speed target value and the comfortable level of train and controls along the railway line，and achieve the goal of obtaining the optimal railway line plan in technology and benefits．
Research conclusions: For the section with the special technical requirements and control sector，the plane design standard for the railway line should be decided in accordance with the operation situation of construction project and researched result of V—S curve．For the sectional track，the plane design standard should be reasonably selected after analyzing the relation of the speed difference between the cross—line train and hish—speed train and deciding the reasonable comfortable level of train and relative super—elevation of track in accordance with the operation situation of construction project and researched result of V—S curve．For the tracks on both ends of station，the plane design standard should be selected after analyzing the relation of the distance between the curve and the center of the station and the relation of the speed difference between the entering and departing trains and high—speed train，and deciding the comfortable level of train and the super—elevation．
