Passenger and freight trains are operated between stations I and II, where the distance between stations is 16 km. The speed of the passenger trains is 100km/h, and the speed of the freight trains is 60km/h for a single-line railway track. The waiting time for passenger trains is 9 minutes, and 2 minutes for freight trains. It is possible to operate 2 freight trains per day, and the daily operation time is 21 hours.
