The Prototype Carborne Monitor Development Project Final Report includes the final technical report, operations manual, and performance specifications developed. This study is a response to the National Transportation Safety Board (NTSB) recommendation R-82-74 regarding onboard recording of safety related data. The recommendation resulted from the NTSB investigation of January 13, 1982, railcar incident near the Federal Triangle subway station in Washington, D.C. The carborne monitor was installed on a Rohr railcar to record 10 analog and 60 digital signals that would be useful in determining the cause of an incident such as derailment or collision. The unit is designed to be fully automatic with self testing start-up features and to automatically "freeze" data in the event of a derailment or collision, the application of emergency brakes or the keying in of the incident switch by the train operator. Thirty minutes of data, prior to an incident and 10 following an incident, are recorded for each of two incidents. In addition to the carborne equipment, software for an off-line data retrieval and analysis system, using a personal computer, was developed, tested and documented. The performance specification reflects all the improvements identified during the operational demonstration and can be used as a technical specification for procurement purposes.
