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 communication via serial protocols.

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 serial protocols to implement safety-related data communication for open transmission systems. In addition, the communication board 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.

Axle Counter Overlay System

Between London St Pancras International Station and Farringdon Station, there is a history of frequent flooding through the tunnels that adversely affected the reliability of the existing train detection system. Due to this, the installation was non-operational during large periods. However, being a mainline section and a core route through London, high reciliation to any sort of failures is vital.

Ensuring reliable rail operations across India´s longest rail-road bridge

The Bogibeel Bridge is India’s longest rail-road bridge that connects Assam and Arunachal Pradesh, carrying both rail and road traffic across the Brahmaputra River. Harsh environmental conditions and structural constraints made conventional signalling unworkable. The Frauscher Advanced Counter FAdC® axle counting system was selected for its proven reliability and low maintenance under these challenging conditions.

Headbolt Lane to Rainford Project

As part of the project to expand Merseyrail services, the operator needed to address the challenge of transmitting indication information over a specific section, spanning from Headbolt Lane to Rainford. In this instance, Frauscher’s technology was utilised to fulfill the data transmission requirements of this project, avoiding expensive and time consuming cabling that would have otherwise been required.
