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.

Charlotte Area Transit System (CATS) Supplementing Audio Frequency Track Circuits with Axle Counters

At the Charlotte Area Transit System, frequent false red signal overruns resulted when electromagnetic interference caused “bobbing” of the line’s audio frequency track circuits. The Frauscher Advanced Counter FAdC was subsequently considered as an alternative to these track circuits to eliminate the occurrence of false red signal overruns.

Tracking Trains in Houston

Houston MetroRail (METRO for short) is comprised of three light-rail lines covering 22 miles. Two-car, low-floor trainsets are powered by overhead catenary and operated on a mix of rail types, including embedded, grooved, concrete, and ballasted track. Harsh weather conditions such as extreme heat, humidity, and storms with heavy rains causing floods are typical for Houston. Combined with the variable track structure this caused significant malfunctions of the wheel sensors of METRO’s signalling system.

City of Calgary Grade Crossing Upgrade

The City of Calgary in Alberta, Canada was seeking an upgrade to the existing signaling system at a crossing near a station in the downtown area, to alleviate shunt issues caused by winter conditions. The Frauscher Advanced Counter FAdC and Wheel Sensors RSR180 were chosen to augment the existing system. During the eleven month trial period, the axle counter ran in shadow mode with the legacy system to gauge performance and compatibility. After the axle counter was proven during the trial with no faults or errors, the city was able to implement a hybrid crossing design using both the axle counting system and track circuits.

Class 1 Yard Project

Frauscher was approached by a North American Class 1 railroad planning a major expansion of one of its yards, and the required time to completion was short. The scope of the expansion was to build an operational multitrack flat yard on vacant land within six weeks with a signalling solution to protect switches during operations.
