On March 17, 2023, Dalian Metro Line 5, the backbone rail transit line connecting the north and south of the core area of Dalian, was officially put into operation. Under the escort of the FITSCO JeRail®CBTC signaling system, the line will accelerate the economic development of Dalian, which is of great significance to the construction of a coastal city on both sides of the Bay.

Dalian Metro Line 5 adopts the JeRail®CBTC signaling system independently developed by FITSCO, which conforms to the relevant standards and industry characteristics of domestic and foreign rail transit signal systems. Combined with the rich application experience of FITSCO in the field of rail transit signaling system, it has the following technical characteristics:

Service experience of CBTC+. Which means under the condition of CBTC line, the automatic operation system features such as superimposed rain and snow mode, platform backsliding safety protection, etc., can provide a better experience for users.

Fail-safe operation. Based on the concept of fail-safe operation, aiming at common fault scenarios in operation, Innovative technology for improving system availability in degraded mode is enriched to weaken the impact of faults and reduce the dependence on external conditions.

Meet customer characteristics. Based on the advantages of autonomous technology, optimize the train mode switching mode, reduce the operating complexity of drivers, and make the driving process more smooth; At the same time, the train control algorithm is refined to provide multiple running grade curves, which can be adjusted automatically and flexibly according to the operation needs.

Intelligent operation and maintenance system functions. Rich system maintenance functions, to provide indoor and outdoor switch consistency inspection and other features to solve the industry pain points.

In order to meet the requirements of Dalian Municipal Party Committee and government for the construction of Dalian Metro Line 5, to ensure the smooth completion of the project node. All members of the FITSCO project team stick to the front line, relying on the flexible innovation of autonomous products, the full use of laboratory testing, and the advantages of timely response, and closely cooperate with various professions to advance in multiple fields. The field engineers overcame difficulties and went all out to successfully complete equipment installation, interval testing, on-board static adjustment, "white + black" 24-hour uninterrupted bullet train test, trial operation and other links, efficiently complete the deep run-in between systems and people and systems, and lay a solid foundation for the official opening and operation of the line.
