Extension Line D Tram Bordeaux

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.

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.

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.

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.

Tram Huangpu Line 1 (HP1) line is located in urban areas with high traffic density and passenger volume as well as many level crossings. The adverse weather conditions can cause flooding of the track bed and add to the challenges for reliable system availability and operations.
