The technology of passenger station includes the flow of operations to service the movement of trains and shunting activity to the technical station representing a common railway complex providing the best service to passengers and using the available technical means. The shunting process at a passenger station consists of activities such as handling trains, taking them out of the technical station and their placement on tracks according to the train assembling plan. The paper examines the work of shunter teams and how the number of teams required to serve the passengers railway complex is determined. The study is aimed at possible improvement of shunting process based on a number of selected indicators theoretically worked out: the number and duration of shunting movements per duty; the number and duration of isolated movements; the stay and utilization of shunting teams; the relative occupancy of station tracks. The implementation of the current schedule for the movement of trains and the existing schedule plan for the work at the Sofia station was analyzed and a new one was developed to improve the work of the shunting teams. The developed new scheme of the shunting process ensures reducing the relative employment of shunting teams and the duration of shunting movements.
