Abstract

We are studying railway operation optimization. Two kinds of trains, local and rapid, are under consideration to investigate the optimization of rapid trains stopping stations by adjusting the stopping stations to reach optimum convenience and rapidity. However, the rapid train has to overtake local trains that are running ahead. Therefore, overtaking facilities need to be considered too. In this paper, we describe the relation between stopping and overtaking station combinations and operation effectiveness. First, the rapid train stopping and overtaking stations are determined by DP (Dynamic Programming), considering real overtaking facilities at stations. Second, the rapid train timetable is determined and drawn on the train diagram. Third, the local train timetable is determined based on overtaking stations. The diagram is drawn for both directions starting from the overtaking station. The evaluation value is the average trip time, and is calculated by the timetable (diagram) and the passenger OD (Origin and Destination) table. By computer simulation using an existing line, we show that the most effective conditions are fewer overtaking stations, and no simultaneous overtaking at a stopping station. Keywords: rapid trains, combination of stopping and overtaking at stations, train timetable, average trip time.
