Computer based interlockings: Electronic interlockings detect and control the logical and vital equipment in accordance with the dependencies between signals, points and vehicles. More advanced than solid state interlocking (SSI), Simis W is the latest computer based system combining high reliability with low maintenance, is adaptable for future requirements and can be integrated with existing control systems.
Control and operation systems: The control and operation of the interlocking is provided by Siemens Vicos systems which use networked components and automated functions to ensure efficient operation – not only of Simis W, but also of other manufacturers’ electronic and relay interlockings. Vicos also offers automatic train-tracking, automatic route setting and SCADA.
Axle counters: Track vacancy detection systems provide reliable information on clear and occupied states of track sections. Siemens solutions include wheel sensors and axle counters.
The Az S 350 U microcomputer axle counting system from Siemens is a fail-safe track vacancy detection equipment for one or more track sections. Az S 350 U has been designed for operators of main line and industrial railways, secondary lines and light transit systems. A universal interface allows connection to any interlocking system. Az S 350 U benefits include:
Low lifecycle costs
Rapid implementation of customer requirements
Easy to modify and extend systems
Low maintenance and repair requirements
Small space requirements
Fault tolerant evaluation of the pulse count signals
Fail-safe computer on the basis of the well-proven Simis® principle
No need for air conditioning
Adaptable to existing power supply systems
