Station arrangement structure and method for driving urban trains by using existing single-track railways

Abstract

The invention provides a station arrangement structure for driving a city train by using an existing single-track railway, which comprises an existing single-track railway main line, a city platform and a city arrival and departure line, the city platform is arranged on the outer side of the existing single-track railway main line, and the city arrival and departure line is located between the city platform and the existing single-track railway main line. A first crossover and a second crossover are arranged between the existing single-track railway main track and the city arrival and departure track, a platform isolation area is arranged on the city platform, and a middle crossover set is arranged at the position, corresponding to the platform isolation area, between the existing single-track railway main track and the city arrival and departure track. According to the method, by additionally building the urban platforms and the urban arrival and departure lines, the urban trains are driven by using the existing single-track railways, meanwhile, the station spacing is shortened, the service level of driving the urban trains by using the existing single-track railways is improved, the main tracks of the existing single-track railways do not need to be changed, and the cost is reduced. And the cost of using the single-track railway or the existing special branch railway to drive the urban train is reduced.

Description

technical field [0001] The invention belongs to the technical field of rail transit, and in particular relates to a station arrangement structure and method for running city trains by using an existing single-track railway. Background technique [0002] At present, a large number of existing special branch line freight railways have surplus capacity, and using the existing special branch line railways to run city trains has obvious advantages such as revitalizing railway assets, reducing construction costs, and achieving "win-win for urban railways". [0003] The special-line railways are mainly single-track railways, and passenger trains are operated at the same time as freight trains. Since the distance between most single-line railways or special-line railways is between 8 and 10km, the running speed of freight trains is low, while the speed of urban passenger trains is low. The distance between stations is required to be between 3 and 5km, the transportation speed of urb...

AI Technical Summary

Problems solved by technology

[0003] The use of special branch railways is mainly single-track railways. Passenger city trains are run at the same time as freight trains. Since most single-track railways or special branch railway stations are between 8 and 10km apart, freight trains run at a low speed, while urban passenger trains The distance between stations is required to be between 3 and 5km. The transportation speed of urban passenger trains is high, and the operation density of public transportation is high. The existing stations of urban passenger trains alone cannot meet the compatibility functions of urban traffic passenger and cargo transportation.

It is necessary to appropriately increase the number of stations on the existing single-line railway or branch line railway to improve the service level of the area along the line, which is the internal demand of urban transportation functions. However, it is difficult and costly to add stations with distribution lines. Operations can also be adversely affected
