Command, Control & Communication (C3) SystemEmpowering thru’ Innovation

Operational PerspectiveThe C3 System design ‘marries’ the requirements ofrailway operators and modern technology to create acost-effective and responsive solution for railwayoperation. This is in contrast to other system whichrequires operational elements to be built around astandard solution. Typical Railway Operations (ServiceStartup, Revenue Service, Shut-down) are fullysupported by the C3 solution.RailwayOperationOperation SupervisionIncident ManagementEmergency ManagementService Startup Revenue Service Service ShutdownTypical Railway OperationSoftware ArchitectureTimeThe C3 System software architecture builds around anEvent Model as described below: Messages are called Events Events are typically system state changes,inter-process communication, and auditing Events The Event service is responsible for propagatingEvents to all relevant subscribers Event delivery is guaranteed by the Event service Modules push Events to the Event service asrequired Modules subscribe to Events in which they areinterested. Modules do not know or care whichother modules have subscribed to the EventWith this model, Modules (Functions) can be distributedanywhere in the system and redundancy can be appliedeasily where required. This architecture is also highlyscalable and can be adapted to suit specificrequirements.Railway Situation ManagementTypically, a railway operates in 3 modes; namelyNormal, Incident and Emergency modes. During normalmode of operation, the C3 System routinely managesthe daily system startup, launching of trains, servicesupervision and train withdrawal at the end of revenueservice.In the course of revenue service, certain abnormalitieslike “Stalled Train”, or “Station On Fire” etc., may arise.These incidents or emergency situations, depending onits severity, require rapid and precise operator’sreactions under a tense environment. In support of suchrequirements, the C3 System includes a DSS tool toguide the actions of the control centre operators basedon pre-defined operating steps or procedures in acontrolled manner based on information received fromvarious sources.For instance, on detection of a “Train On Fire”emergency situation, the corresponding DSS plan willautomatically be activated and a series of operator’ssteps/actions will be displayed. Such steps wouldtypically include: Select and display video of affectedtrain to assess situation, call station staffs andemergency services on direct line, stop train services inaffected sector, send appropriate emergencyevacuation messages via train-borne PA and signage,identify and confirm location of affected train and selectappropriate tunnel ventilation mode to facilitateevacuation of passengers etc. This systematicapproach provided by the tool minimizes the chances ofoperator’s errors during abnormal and tense situations.The DSS is fully configurable to suit various operatingscenarios defined by the railway operator.Specifications subject to change without prior notice.PowerCompanyFireBureauRailway OperatorManagementC3 RailwayControl CentreChief C3 SupervisorTransportRegulatorPoliceEmergencyServices TrainRegulatorPowerRegulatorFacility/Security /RegulatorFaults& WorksCoordinatorTypical C3 Supported Railway Operational OrganizationSINGAPORE TECHNOLOGIES ELECTRONICS LIMITED24 ANG MO KIO STREET 65 SINGAPORE 569061TEL: (65) 6481 8888 FAX: (65) 6482 1803WEBSITE: www.stee.stengg.com(Regn.
