Initialization failure
Initialization failure means any instance when a PTC system fails to activate on a locomotive or train, unless the PTC system successfully activates during a subsequent attempt in the same location or before entering PTC-governed territory. For the types of PTC systems that do not initialize by design, a failed departure test is considered an initialization failure for purposes of the reporting requirement under 236.1029, unless the PTC system successfully passes the departure test during a subsequent attempt in the same location or before entering PTC-governed territory.
