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.

Frauscher axle counters have been separately integrated into the interlocking systems of the 9 lines in Beijing- Yizhuang Line, Changping Line, Beijing Line 8, etc. covering in total 226.35 km with an average daily passenger flow of 266,000. Furthermore, the axle counters had to be SIL 4 certified. The ACS2000 with IMC and RSR180 was the preferred system by the three signalling operators and a total of 763 wheel sensors across 645 track sections were installed. A wide range of rail claws satisfied the multiple rail track requirements on the network, such as slab and ballasted track. Easy and fast mounting of rail claws allowed a timely and cost-efficient installation.

After over 10 years of operation, the ACS2000 has proven its outstanding stability and reliability. Furthermore, the ACS2000 has not only fulfilled all the operating requirements but has also always guaranteed a smooth operation of the metro lines.

Excellent match of requirements

The ACS2000 has fully met all the strict challenges outlined in this project as well as the operating requirements set by both the integrators and the operators.

Significant reduction of time

Easy and fast mounting of rail claws allowed the installers to greatly shorten the timescale of the entire project.

Highest flexibility

The modular design of the ACS2000 offers clients the highest flexibility in daily operation, including a simple, fast and efficient reset process which significantly reduces the Mean Time to Repair (MTTR).

Toronto Transit Commission | Canada

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.
