Abstract: In this paper, we propose a method for quantifying the resilience of high-speed railway train diagram (HSRTD) under section interference. The resilience of HSRTD is defined as the ability to resist, adapt to the impact of section interference, and quickly recover to normal operation state from the impact. Firstly, by establishing a HSR train operation control model based on cellular automata, the real-time control and feedback of affected train number and affected time under section interference can be obtained. Then, from the three aspects of resistance ability, adaptation ability and recovery ability, six indicators including vulnerability, redundancy, absorbability, survivability, sensitivity and dependency are selected to quantify the resilience of HSRTD. Next, three strategies including removing some operation lines, moving some operation lines, removing and adding some operation lines are proposed for restoring and adjusting the operation of HSR trains under section interference. Finally, the Xi'an North-Baoji South HSRTD is selected as a case study to compare and analyze the resilience quantification results with different recovery and adjustment strategies under section interference. Among the three strategies for adjusting the HSRTD, removing some operation trains in the affected area has the most significant effect on improving the resilience of the HSRTD.
