  • Publication number: 20150276555
    Abstract: A train test platform for testing actual train components of a multiple car railway train and a method to test such actual train components includes a supervisor unit and several car units linked by a reflective memory system. The actual components to be tested are installed in instrumentation units of the respective car units. The instrumentation units provide break-out interfaces for connecting the actual train components to a train communication system having the wiring, bus systems, or power supplies Further the instrumentation units simulate those components not being present physically in the respective cars. Testing is performed by monitoring and manipulating signals at the break-out interfaces in real-time. All testing is controlled by the supervisor unit using the reflective memory to exchange information with the platform components in the respective car units.
