Abstract Research purposes: Generally，some influence factors can not be fully reflected in the calculation formula of carrying capacity，such as the time and modes of the comprehensive window maintenance，and the influence of quantity of arrival and departure track in intermediate station on the transport organization and carrying capacity，etc．This paper analyzes the influence factors on Datong—Qinhuangdao Railway，and puts forward a new calculation method for the carrying capacity of Datong—Qinhuangdao railway for being as the valuable reference to survey and design of heavy—haul railway．
Research conclusions: The particularity of calculating carrying capacity of Datong—Qinhuangdao Railway mainly reflects in the following three aspects：(1)There are two kinds of comprehensive window arrangement，namely V—mode and vertical skylight and they occupy the different time of train diagrams．(2)The quantity of arrival and departure track in intermediate station will directly influence the loss window time outside maintenance．(3)The number of V—mode and vertical skylight will influence the daily carrying capacity of the railway．
