Project Overview

The Shanghai Rail Transit Airport Link Line starts from Hongqiao Railway Station and ends at Shanghaidong Railway Station, passing Pudong International Airport Station along the way, with a total length of 68.6 km, 9 stations on the main line and a maximum design speed of 160 km/h.

The line connects two international airports in Shanghai, Hongqiao and Pudong. After operation, the travel time between the two places can be shortened from 90 minutes to 40 minutes. At the same time, the line links up Shanghai Hongqiao Railway Station, Shanghainan Railway Station and Shanghaidong Railway Station along the route, which will also help realize the seamless connection between the railway hub and airports and the urban transportation in Shanghai, and promote the integrated development of higher-quality transportation in the Yangtze River Delta.

Products and Services Provided by CASCO

CASCO provided efficient and intelligent suburban railway signaling system solutions, including centralized traffic control system, interlocking system, trackside train control system, which significantly enhanced the mass transit function based on the CTCS2+ATO system, while meeting the future demand for networked operation of national railway trains on Shanghai Rail Transit Airport Link Line.

Compared with the existing standard CTCS2+ATO system of national railway, this system features the following innovative breakthroughs:

• • It has realized the automatic turnback (ATB) function to meet the requirement of operating interval within 3 minutes for the whole line, which is one of the important innovations in mass transit operation.
• • Integrating the dispatching systems of existing national railway and urban rail transit, it has created a suburban railway networked dispatching management system that supports interconnection with national railway lines and mass transit of urban metro lines.
• • While promoting mass transit, it supports cross-line operation and meets the needs of mass transit and networked operation.
• • Based on the integration of dispatching and train control systems, the interface between the dispatching system and other subsystems is expanded. In addition, the information among dispatching, train control and other disciplines is exchanged and integrated to realize multi-disciplinary information linkage with intelligent dispatching system as the core, providing technical support for efficient operation, emergency disposal, multi-disciplinary collaboration and low-cost maintenance.
• • The flexible train foundation operation with 4 or 4+4 cars configuration, which has been realized to meet the demand of tidal passenger flow and achieve the precise deployment of transport capacity.
