    Abstract
  • According to the actual transportation mode and operating character of passenger trains and freight trains running together on busy existed railway main-lines, the existed calculating methods of carrying capacity were analyzed, and the study principle and the definitions of period and calculated division were set down. By analyzing the time of train interval and the overtaking between different class trains, the improved mode of negative index distribution was adopted, and the planning model and calculating method of period carrying capacity on busy existed railway main-lines were advanced.An example of certain division in up train graph on Huning line was given to explain the new method.Calculation result indicates that the academic numerical values of four period carrying capacities are 53, 26, 49 and 43 respectively, which accords with the actual situation of busy main-lines, so the model and method are feasible.
