Express and local trains can meet passengers' various travel needs effectively, reduce transport operation costs, and promote the service level of urban rail transit. For a train system to be effective, it is crucial that reasonable stop schemes be created. First, the study examines, in detail, the feature of overtaking between express trains and all-stop trains. The overtaking of local trains by express trains not only results in increased passenger travel time and train turnaround time, but also reduces carrying capacity. This study puts forward a scheme wherein express trains overtake all -stop trains at slow stations, without stopping, to reduce the adverse impact of overtaking. We then analyze passenger trave1 time and the operation costs of express and local trains, we establish an optimization model for the stop scheme of express and local trains, and use a genetic algorithm to solve it. Our results indicate that this scheme saves passengers 3,976,815 seconds of travel time, and train operators one set of train stock and a 12,OOO-yuan stop cost during the peak trave1 hour.
