2. An experienced signal engineer must verify the safety of the VPI data and its application lt is the signaling engineer s responsibility to verify the correctness of the VPI input data in that it accurately represents the intended safe functionality of the VPI system Furthermore verify the correctness means that the signaling engineer 1 is required to compare the input and output data files to verify the CAA has operated correctly and 2 must test the VPI application in its intended environment before it can be placed in revenue service Failure to comply can degrade the safety performance of the train control system resulting in property damage injury and or death due to train collision or derailment P2086G Rev E Jan 15 5 39 Alstom Signaling Inc Vital Subsystem A WARNING VPI APPLICATION MUST BE VALIDATION TESTED Prior to revenue service validation testing must confirm all VPI application logic is correct and consistent with application requirements Failure to comply can degrade the safety performance of the train control system resulting in property damage injury and or death due to train collision or derailment The basis of the application of VPI is to use a tool to configure the system hardware and software as well as create the signaling logic for the Vital application The independent Application Data Verifier Tool as well as associated procedures must be run and performed prior to any VPI applicat
