It is one of critical tasks to reschedule timetable timely in high-speed railway (HSR) operation system. Multi-disturbances, i.e., primary delay, speed limitation or blockage of dwell lines, are considered in this paper, where a mixed integer linear programming is formulated based on the alternative graph to minimize the sum of times of changing dwell lines and secondary delay. Therefore, train real-time speeds, train orders, running times and occupations on dwell lines are adjusted and optimized simultaneously. In order to solve this complex model within a limited time, a new-designed solving algorithm applied in an actual case, i.e., timetable of Wuhan-Guangzhou high-speed railway, and it is able to provide an acceptable solution efficiently, and the validity and feasibility are demonstrated as well during the computation process. At last, delay times and frequencies of changing dwell lines caused by different disturbances are computed and analyzed during the experimental tests.
