Scope of project
565 wheel sensors, 103 equipment locations

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.

In order to improve the system, METRO conducted trial installations with several suppliers of axle counter solutions to demonstrate features and the overall performance of their respective products. Due to the complicated track structure and environmental conditions, Frauscher quickly understood that the required wheel sensors had to be simple to install, immune to extreme heat as well as waterproof as floods could easily occur. The trial results demonstrated that the Frauscher Advanced Counter FAdC® met all of METRO’s requirements in terms of environmental influences, interfaces, reliability and seamless integration into the existing infrastructure.

The flexible design of the FAdC® allows efficient data transfer via relay interface to the traffic control system and interlocking. Additionally, two optional intelligent functions, Supervisor Track Sections and Counting Head Control, were used to counter the effects of unexpected influences such as metallic debris. The installed Frauscher Wheel Sensor RSR180 is extremely robust and not affected by any environmental influences.

In total, 565 Wheel Sensors RSR180 were installed along the rail line, and the axle counter Frauscher Advanced Counter FAdC® in 103 locations throughout the network to guarantee a flawless operation of the line.

Excellent match of requirements

The Frauscher axle counting solution met all of METRO’s environmental, interface and reliability requirements. The straightforward installation and smooth transition from the existing train detection system was highly appreciated by the operator.

Reduction of costs

The new system caused a significant reduction in down time and maintenance costs, which will continue to add up over the lifecycle of the system. The additional smart functionalities that were implemented increased the availability of the system even further.

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.

Jhansi - Bina Railway Line | India

The Jhansi-Bina railway line is a strategically important line which belongs to North Central Railway and is in Uttar Pradesh. Initially, the line featured analogue axle counters for detecting trains in individual track sections as well as a DC track circuit train detection system in less congested areas.

Axle Counter Overlay System | UK

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.

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.

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.
