Westrace  MKII System  Architecture – Block Diagram

WESTRACE  MkII  is a processor based vital signalling system, designed, manufactured and   supplied   by   Invensys   Rail.   The   inputs   (tracks   detection,   local   panels,   alarms,   etc)   are   processed by the microprocessors A and B, which execute the same logic. According to the   state   of   the   inputs,   the   microprocessors   change or not   the status of   the   outputs.

Westrace System and Safety advantage. WESTRACE MkII is a safety critical, processor based railway signalling system. It is generally used for interlockings. It is a suitable for passenger and freight railways and has been independently certified to meet the stringent safety principles for this equipment. WESTRACE MkII : Advange meets world Safety Integrated Level 4(SIL 4). features modularity; is easy to maintain; is robust, and; Has cost advantages over conventional interlockings (Reduction in use of relays based interlocking) The system encompasses all of these features but safety is foremost. WESTRACE equipment is suitable for safety critical applications. Each WESTRACE module uses a 2oo2 (2-out-of-2) safety architecture. Modules use two processing or hardware paths with separate processors. Both paths must agree before an active input will be accepted or an active output driven. Modules that generate different states are automatically shut down. The only impact that failure or removal of a module has on the interlocking is the absence of it’s associated inputs and outputs. The interlocking continues operation..
