Purpose. This paper presents the calculation method and result of reasonable station spacing in the organization of mixed high-speed passenger and freight transportation, at different speed combinations and different types of train schedules.
Methodology. By using the principle of the shortest distance between stations, this paper analyzes the possible layout of passenger and freight trains running at different speeds between Brest and Moscow, and work out the optimal distance between overtaking stations. According to the shortest distance between stations, the blocking method with four-digit automatic should be used when the maximum speed of the passenger train is 250 km/h. The crossing scheme for different types of trains is determined, and the train schedule period (TDS) of each scheme is determined. Calculate the appropriate distance between stations that had been passed through with different trip intervals according to the characteristics of the passing passenger and freight trains. By adopting simulation analysis, the influence of different number of trains and their composition on the station spacing is simulated to work out the reasonable railway station spacing for passenger and freight train with a speed of 250 km / h.
Findings. In the case of passenger and freight traffic with the speed of 250 km / h, the optimal distance for stations between Brest and Moscow should be around 35 km. In order to make effective use of the existing infrastructure and achieve maximum transit capacity of the railway, it is recommended to increase the speed of the low priority trains.
Originality. The distance between stations on a line will affect the number of stations on the entire line, as well as the maximum train speed and the number of train pairs. Excessive or insufficient station spacing will affect the transportation capacity and efficiency. Therefore, reasonable station spacing will determine the number of trains and the maximum speed of each train for both passenger and freight.
Practical value. This paper proposes a method to estimate the reasonable spacing between crossing stations, which can ensure the effective utilization of the capacity of railway sections when high speed passenger trains on existing lines are running at speeds of up to 250 km/h.
