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.

In 2019, Network Rail started to look at how to improve the overall reliability of the railway without removing the existing detection system. The main requirement was guaranteeing maximum availability considering the local conditions without interfering with the existing installation.

Due to its great reliability under such circumstances the Frauscher Advanced Counter FAdC® has been chosen as the most appropriate solution. The FAdC’s® modular design allowed for the establishment of a decentralised architecture, where four external location cases were installed between the two stations to host the axle counter’s indoor equipment. The system is supported by the Frauscher Wheel Sensor RSR123, which precisely tracks every train axle. The sensor is extremely resilient to water penetration and other environmental and external influences. Thanks to the IP68 rated housing, it even works reliably in case of floods.

Excellent match of requirements

The FAdC® units installed in location cases between the stations can communicate with one another via a vital Ethernet interface and also with the higher-ranking system using relay outputs. With overlay systems, the new track sections had to match the existing track section limits. Therefore, the system had a specific requirement to install the RSR123 within 0.5 m of the existing train detection system and within proximity of the neutral section to avoid any impact on the signalling controls.

Great resilience

The RSR123 is highly resilient against any interference or environmental influences.

Dillinger Hütte | Germany

A new ladder track was required to provide more parking tracks in the steel plant. At the same time, the layout of the dead end tracks were optimised and the efficiency of the whole depot improved by installing the Frauscher Advanced Counter FAdC®i in combination with the wheel sensor RSR180. With the implementation of the Frauscher Diagnostic System FDS, the overall maintenance costs can be significantly reduced.

Maintaining the past, creating the future | UK

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.

Renewal signalling FAdC® and RSR123 | Denmark

Banedanmark, the Danish railway infrastructure owner, started replacing the existing signalling system in the Eastern region of Denmark in 2009 to implement the newest proven signalling technology, based on standard industrial hardware components and redundant system configurations. Uniform system interfaces should reduce signalling failures to provide a better reliability and punctuality of the entire network. For this project, Frauscher delivered the Frauscher Advanced Counter FAdC® and the Frauscher Wheel Sensor RSR123.

CBTC Fallback System on Beijing Metro Lines | China

Beijing metro, one of the busiest lines in the world, was Frauscher’s very first assignment when entering the Chinese market. Due to its utilised capacity, it requires a great level of stability, reliability and performance of the entire signalling system. The Communication Based Train Control System (CBTC) applied here relies on a backup system consisting of fixed automatic train detection systems. Axle counting systems from Frauscher are perfectly suited for the accurate operation of such stand-by systems.
