The Vijayawada Division of Indian Railways introduced a new train detection system with data transmission functionality to overcome the challenges of the existing BPAC and conventional quad cable-based systems. Frauscher implemented the Frauscher Advanced Counter FAdC, featuring full redundancy, advanced reset mechanisms and remote diagnostics. This upgrade delivers significant cost savings and enhanced system availability for the operator.

The Vijayawada Division Intermediate Block Section projects aimed to upgrade and transform the division with a modern signalling system. Using Frauscher Advanced Counter FAdC, with data transmission functionality, the division was able to improve reliability and efficiency.

The project covered 24 intermediate block sections over approximately 264 kilometres and 360 detection points.

The SIL 4-compliant, FAdC was chosen for this project due its benefits in solving the challenges faced by the customer. The solution integrates advanced features such as dual detection, full redundancy, Supervisor Track Section (STS) auto-reset, and Counting Head Control (CHC), ensuring high availability and safety. The data transmission functionality also enabled secure transmission of both vital (track vacancy, signal control) and non-vital (signal status, alarm) information via a dual-path network using optical fiber and redundant quad cables.

Pre-wired cubicles and easy installation of RSR180 ensured minimal on-site disruption. Furthermore, the Frauscher Diagnostic System (FDS) was integrated with Indian Railway’s RailNet network, which allowed real-time web-based remote monitoring.

This upgrade project not only reduced operational costs and maintenance needs but also created a future-ready, modular infrastructure capable of supporting ongoing digital transformation in Indian Railways.

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.

City of Calgary Grade Crossing Upgrade

The City of Calgary in Alberta, Canada was seeking an upgrade to the existing signaling system at a crossing near a station in the downtown area, to alleviate shunt issues caused by winter conditions. The Frauscher Advanced Counter FAdC and Wheel Sensors RSR180 were chosen to augment the existing system. During the eleven month trial period, the axle counter ran in shadow mode with the legacy system to gauge performance and compatibility. After the axle counter was proven during the trial with no faults or errors, the city was able to implement a hybrid crossing design using both the axle counting system and track circuits.

Renewal signalling FAdC and RSR123

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.

Tracking Trains in Houston

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.
