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.

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.

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.

Axle counting adds fail-safe control to laser diagnostics

When MERMEC set out to install a laser-based Wheel Profile Measurement System in close proximity to the Eurotunnel, they faced a critical challenge: how to avoid unintended laser exposure without compromising the system’s ability to inspect up to 200 trains per day. To meet these requirements, MERMEC partnered with Frauscher.

Three-rail Castellbisbal

The dual-gauge system of the Spanish railway network is quite challenging in terms of track vacancy detection: Wheel sensors must be installed on two rails next to each other in tight spaces and have to detect axles reliably on the respective rail. Frauscher developed a solution which copes also with the complexity of different interlocking technology in the stations along the line.
