The main contribution of this paper is considering the capacity of trains and stations, as well as the assumption of a constant interval for travelling between two successive stations. To reach this aim, the sum of dwell time and travel time are assumed constant. The dwell time is considered a function of number of passengers who can board the train. To show the effectiveness of the proposed model, a numerical example is studied. The parameters of the metro system are considered according to Tehran Urban and Suburban Railway Operation Co. The results show that an increase in the capacity of trains and the number of trains separately leads to the reduction of total waiting time. Furthermore, the best amount of Headway in order to minimize the waiting time is six minutes.
