Abstract
A method and monitoring unit for recording the status of a railroad vehicle prior to a potential accident. In a monitoring unit mounted in or on a railroad vehicle, such as a locomotive, a video camera is provided to continuously view a scene that the railroad vehicle approaches. The monitoring unit continuously monitors the status of an emergency brake of the railroad vehicle and the status of a horn of the railroad vehicle. Video signals from the video camera are continuously stored. A control unit in the monitoring unit detects the application of both the emergency brake and blast of the horn within a predetermined time window. Video signals from the video camera are captured for a predetermined period of time after detecting that the application of the emergency brake and horn blast within the predetermined time window.
