In 2014, 94% distribution in Indonesia used by truck mode. But in recent years, the train mode begun to be used as a distribution transport mode of replacement trucks. For shipments with a distance of 500-1500 km, rail mode is more suitable due to cheaper transportation costs and faster delivery times. But in Indonesia railway infrastructure is only used 56% of total capacity. Therefore the current logistical challenge is how to optimize the use of railways. This research tries to develop mathematical model for determining freight trains that avoid the ovetaking. The model developed is a train slot model that inserts a freight train between fixed trains. Because there is a lot of input schedules, it requires a long computation time. Therefore, this research also develops decision support tools using Visual Basic Application in Microsoft Excel. The result showed that minimum headway effect on the determination of additional freight trains and the optimum minimum headway is 6 minutes. With 6 minutes of minimum headway, the additional freight train are 15 trains. This additional train increase the carrying capacity of 900 TEUs / day. When compared with the initial condition, it means the addition of transport capacity is 21,43%
