MicroLok II

The MicroLok II multi-purpose wayside controller has become the rail industry’s dominant package for performing vital and non-vital management of signaling systems. As of January, 2012 over 2800 units were operating on five U.S. and Canadian Class I railroads, eight U.S. mass transit systems, rail lines in three European countries, six different rail lines in Australia, several major mass transit lines in China and 14 rail lines spanning India to Malaysia.

Since the first MicroLok II equipment was first installed in 1996, the system has provided fault-free service for tens of millions of operating hours (cumulative). Installations now range from simple end-of-siding to double-track universal crossovers, and include advanced applications such as Driverless Automatic Train Control (ATC) and Communications-Based Train Control (CBTC).

In addition, the system has been given expanded duties (from its original deployment as an interlocking controller) for applications such as dark territory and highway crossing control. MicroLok II can also be configured as a full, standalone non-vital controller, providing “code line” serial communications with a central office and numerous local I/O channels for equipment such as Local Control Panels and ground detectors.
