Heavy-haul Train’s Operating Ratio, Speed and Intensity Relationship for Daqin Railway Based on Cellular Automata Model
Feng Fen-Ling and Lan Dan

Abstract:
Proper allocation of the trains in terms of speed, intensity and carrying capacity is key to the railway line’s operational competence. Based on the four-aspect fixed block system, a cellular automata model was constructed for Daqin Railway in China by combining the rail transit system and cellular automata model. In consideration of the present station equipment, rail line conditions and transport modes, different train track ups and train delay propagation were simulated based on train length, way to enter the station and other factors. Hence, the model was proved to show a true-to-word picture of Daqin Railway operations. Many schemes were achieved through relationship analysis between the operating ratio, speed and intensity. Through comparative studies, the schemes were optimized for different carrying capacity, speed and intensity conditions and then an optimized one was chosen. The results showed that the higher proportion of 20,000-ton trains then the scheme would be more optimal. However, in view of the cargo source organizing, empty train organizing and available equipment, all being 20,000-ton trains are impossible.
