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.

Reducing Delays in a Metro (subway) Environment

A large metro operator was researching ways to reduce bottlenecks that were causing significant delays at a busy station. With two routes dividing in close proximity to the station and a complex auto-routing system that required the use of a 30-second timer to release switches, trains would frequently back up when approaching the station.

Headbolt Lane to Rainford Project

As part of the project to expand Merseyrail services, the operator needed to address the challenge of transmitting indication information over a specific section, spanning from Headbolt Lane to Rainford. In this instance, Frauscher’s technology was utilised to fulfill the data transmission requirements of this project, avoiding expensive and time consuming cabling that would have otherwise been required.

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.

Increasing Availability at Adra Yard

Adra Yard belongs to the Southeastern Railway Zone of Indian Railways and is in West Bengal. Initially the yard was equipped with track circuits and there was a requirement to get them replaced with the Frauscher Advanced Counter FAdC®. This project is one of Frauscher’s esteemed Indian Railway Projects with a coverage of 139 counting heads and 97 track sections.
