The Influence of Maintenance Window Configuration on the Carrying Capacity of Shuohuang Railway

摘要

Shuohuang Railway is a typical heavy-haul railway with coal transportation in China. In this paper, the influence of maintenance window setting on the carrying capacity of Shuohuang Railway is studied. Firstly, the factors affecting the traffic volume of Shuohuang Railway are analyzed in terms of the overall situation. Then the main factors influencing the traffic volume under different maintenance window schemes of Shuohuang Railway are selected, and then the calculation method of the carrying capacity of double-line parallel operation diagram and non-parallel operation diagram is deduced under the condition of the configuration of maintenance window in Shuohuang Railway. Based on this, the influence of maintenance window setting on traffic volume is quantitatively described. The research proves that under the conditions of the existing train running, all kinds of trains in Shuohuang Railway can stop evenly in front of the maintenance window, and the number of arrival-departure tracks will not affect the traffic volume under the condition of maintenance window setting. Considering the slow running after comprehensive maintenance or not, the theoretical calculation capacity exceeds the actual traffic volume, which provides a theoretical basis for the further optimization of transportation organization and the improvement of transportation capacity of Shuohuang Railway.
