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.

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.

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.

Edmonton Metro Line

The Edmonton Metro Line was experiencing significant issues with its newly installed Communications Based Train Control (CBTC) signalling system, which did not perform to the operator‘s expectations. The city was forced to run an incomplete schedule with reduced train speed and frequency which negatively affected commuters and the city of Edmonton in general. Finally in 2019, the operator decided to install a new system in cooperation with Frauscher.
