Research on Technical Standards for Urban Railways Connected with Urban Fast Rail Operations
The connection and operation of urban railways and urban express railways have a profound impact on the system format and technical standards of both.How to determine reasonable technical standards is the focus and difficulty of preliminary research.This article takes the Suyuzhang Line of the urban railway as an example to analyze the interconnection and interworking methods between the Suyuzhang Line and the urban fast rail Line 10 from the perspectives of passenger flow demand,resource sharing,adaptability to system capacity.It proposes to adopt segmented transportation and consider connectivity.Based on functional positioning and passenger flow requirements,we will coordinate with Line 10 to build a north-south urban expressway framework,and comprehensively compare and select speed target values from multiple dimensions.We will conduct a systematic and comprehensive economic and technological comparison and selection of vehicles from the perspectives of network coordination at all levels,supporting investment in various specialties,and vehicle life cycle cost.It is recommended to use a design speed of 160 km/h,and the vehicles will use urban A-type vehicles.It is recommended that Line 10 adopt an AC 25 kV power supply system,maintain consistency with the power supply system of the Suyuzhang Line to ensure the reliability and flexibility of the connection and operation of the two lines.
