Interoperability CBTC System

Background

The expansion of urban rail network has increased the demand for cross-line operations; while traditional CBTC systems, which are limited to single lines and fails to achieve compatibility or coordination betweendifferent signaling systems, proves inefficient cross-line operations and inconvenient transfers. Therefore, the development of an interoperable CBTC system has become an urgent need.

Policy documentsrelated to CBTC systems from the Ministry of Transport, as well as the T/CAMET 04010-04013 specifications issued by the China Association of Metros, including aspects such as interoperability systems, interfaces, testing, and engineering, provide guidance for the development of the industry.

Product Features

Cross-Line Coordination to Improve Rail Transit Network Efficiency
I-CBTC enables interoperable, shared-track, and cross-line operations based on unified standards, significantly improving overall network utilization and reducing passengers’ transfer waiting times.
Resource Sharing to Reduce Operational Costs
Designed and developed in align with I-CBTC standards, the system supports mixed operations of shared tracks and crosslines, and flexible dispatching across the rail transit network. Cross-line express operation across multiple routes improves passenger travel efficiency. Meanwhile, the system is compatible with onboard equipment and ground systems from multiple manufacturers, reducing redundant deployment costs and shortening commissioning cycles for new lines.
Depot Sharing to Maximize Track Utilization
With a shared depot model, the system supports co-location of depots for multiple lines, joint use of depot land and stabling tracks, and integrated management of equipment, power supply, communications and other infrastructure, enabling cross-line reuse of assets, dynamic train allocation, and intelligent coordination of power systems.
Dynamic Emergency Response to Ensure Operational Stability
With dynamic network-wide capacity coordination, the system enables real-time adjustment of train routes and density. This allows rapid evacuation of passenger flows from congested stations caused by sudden surges in ridership or line failures.
Standards-Driven Development to Foster Ecosystem Collaboration
By taking a leading role in the formulation of core interoperability standards, our product promotes ecosystem compatibility for multi-vendor equipment, breaking down technical barriers for cross-line operations, and facilitating industry collaboration and integration.

Application Examples

Chongqing National I-CBTC Demonstration Project of Urban Rail Transit Interconnection: As China’s national demonstration project for urban rail transit interoperability, it takes the lead in applying the I-CBTC system. Adhering to independent innovation, TCT spearheads breakthroughs in key interoperability technologies. The system has been successfully deployedon four lines in Chongqing, showcasing national I-CBTC demonstration and establishing a Chinese-standard I-CBTC industrial chain. The project has generated significant influence and a strong demonstration effect within the industry.

Nationwide Deployment:I-CBTC has been successfully applied across21 lines in 18 cities nationwide, with a total mileage of 681.6 kilometers.
