Abstract: Based on the analysis on optimal overtaking scheme for a single passenger train and calculation of minimum coefficient of passenger train removal, different passenger trains are categorized according their intervals on a train diagram. A method for determining the optimal overtaking scheme and an algorithm for calculating the coefficient of removal are proposed for multiple passenger trains with influence sections intercrossing on train diagram. The formula for calculating the coefficient of passenger train removal with given passenger train scheme is presented. The accuracy of calculation is verified with an example.
