The Wherry Lines are railway branch lines in East Anglia in the East of England, linking Norwich – Great Yarmouth – Lowestoft. The project aimed to integrate Frauscher Advanced Counter FAdC® into two external systems to mitigate against a train passing a red signal without authority on approach to level crossings. Both systems were required to be a SIL 1 level and have the ability to communicate with an ElectrologIXS Interlocking.

For the Wherry Line project, two systems were implemented to mitigate against a train passing a red signal without authority on approach to level crossings. The first system being a method of predicting the likelihood of a train passing a signal based on its speed, the second being a Fast Acting SPAD Trigger (FAST) in the event that a train does traverse past a signal showing a red aspect.

The customer preferred to use the Frauscher equipment that was already installed on site for another project, consisting of the Frauscher Advanced Counter FAdC® and Wheel Sensor RSR123. This decision was made in favour of reducing lineside equipment while also reducing maintenance costs for the future.

As no data of previous speed measurement accuracy was available, Frauscher facilitated and undertook tests to determine the accuracy of the speed measurement at the speeds requested by the customer. Additionally, a formal SIL assessment was successfully undertaken by Atkins to achieve the required SIL 1 level for the system.

Lower maintenance costs

By using existing trackside equipment, no further installations were needed which reduces the required effort and costs for future maintenance.

Easy integration

The FAdC® proved its flexibility and versatility as an optimal solution for this project: It offers the ability to communicate with the customer’s protocol and can be easily integrated into existing systems.

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.

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.

Homologation for the Île-de-France tramway network

The network of Île-de-France tramways in the region of Paris has been a showcase model of public transport since the line T1 opened in 1992. Over a million passengers use these trams daily and today, the system consists of 11 lines covering over 100 kilometres of track. Over the next years it is planned to expand this network even further. For track vacancy detection, the Frauscher axle counting system is considered as being the ideal solution for this comprehensive network.
