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.

Toronto Transit Commission

The Toronto Transit Commission (TTC) Line 1 Yonge-University is Toronto’s longest subway line, with track circuits utilized for signalling. Due to an increasing number of daily passengers and an aged system the need for upgrading without interfering with the daily operations became readily apparent. It was further required that the new signalling system functions independently of the existing system. It would provide CBTC fallback functionalities, and work as an overlay to the current track circuit-based system.

Maintaining the past, creating the future

The Dean Forest Railway (DFR) operates a historical 7 km passenger service line running north from Lydney Junction to Parkend, in the Forest of Dean. Due to extensions of the line and an additional turnout being added at Parkend, an update and modernisation of the existing train detection and signalling system was necessary. Being a heritage railway, it requires high standards in terms of signalling and safety, whilst maintaining the historical touch of the line.

GKB Graz-Köflacher Bahn

The operator of the Graz-Köflacher Bahn has made substantial modernisations to the network, choosing a decentralised system architecture and the EULYNX standardised interface. In this case, it was crucial that the new system would ensure a seamless transition from the previous parallel interface for relay systems to EULYNX.
