Chengdu Tram Line 2 | China

Download Case Study

Chengdu Tram Line, located in the capital Chengdu City of Sichuan Province, is the first tram line to be operational in the city since 2018. The overall line is Y-shaped, with a total length of 39,3 km and 47 stations. It is also the first line in China to be equipped with the new generation Frauscher Advanced Counter FAdC® that supports the communication protocol FSFB/2. 

To ensure an optimal operating environment, this project uses a relay hardware interface and a customised Ethernet-based software interface in conjunction with the FAdC®. The modular and scalable design of the software interface allows it to be seamlessly integrated into more complex high-level systems and interlocking systems.

With inductive sensing on the FAdC®, train detection becomes more reliable and accurate. In addition, intelligent functionalities such as STS and CHC help suppress accidental induction and customise the number of suppressions. These functionalities play a pivotal role in this project because the track is built on public streets and metallic debris scattered on the track could cause interferences and affect the wheel sensors. The CHC function takes care of this by suppressing accidental fault or occupancy messages triggered by external effects. Meanwhile, STS helps operators save time as it resets faulty track sections automatically, eliminating the need for manual intervention.

The FAdC® supports integrator-specified protocol FSFB/2 to implement safety-related data communication for open transmission systems. In addition, the communication board COM-FSFB is SIL 4 certified.

Reduced maintenance costs

State-of-the-art communication technology, customised safety protocols and intelligent functionalities of the FAdC® have reduced the space occupation, energy consumption and overall maintenance costs for the Chengdu line.

Smart functions for maximised availability

Intelligent functionalities such as STS and CHC suppress error messages caused by accidental interferences and enable faulty track sections to be reset automatically, ensuring failsafe functioning, and further increasing the availability of the system.

Seamless integration into higher-level systems

The software interface has a modular and scalable design, delivering a high degree of flexibility in design and enabling the FAdC® to be easily configured and integrated into other systems.

FAdC® at Uglerudnaya Station | Kazakhstan

AcelorMittal is the operator of the Uglerudnaya industrial railway station, located in Temirtau, Kazakhstan. The station features a total of 56 switches and 52 track sections to enable the smooth flow of train traffic. To ensure the safety of all trains, an interlocking system is used to establish secure routes for incoming, outgoing, and passing trains. This requires effective traffic management and a dependable train detection system to detect the presence of trains on the tracks.
