On Integrated Train Operational Scheme Drawing-up Platform of China

The paper analyzes the historical development of railway train schemes since 1949. Four stages have been summarized to embrace different characteristics and issues existed in different times according to their procedures. From the viewpoints of methods and techniques involved in above four stages, the authors describe the key models and algorithms applied in train scheduling, locomotive and crew work plan, yard operational plan and experimental analysis of train timetables. Based on the studies delivered in the field during the past decade, authors advance an integrated framework which deals with its major functions, key theoretical and technological progresses and several applications of the platform, including ones in improvements of railway station design, signal layout optimization, train scheduling evaluation at microscopic level and possible other applications in the construction of high-speed railways of China.
