I am trying to figure out why the motorman would even think of maliciously crashing the train with the full knowledge every action, response , warning system is being monitored/recorded and observed by black boxes. One thing for sure, the first response from management anywhere is always "operator error." Heard that phrase more times than I can count. First thing an operator learns, documentation: put it in writing. Seems problems with the equipment is well documented: PLC, brakes. Indeed , wait and see. Only thing is, will probably die of old age before the truth is known.
