Abstract

This disclosure relates to a system configured to detect rail vehicle events. Some or all of the system may be installed in a rail vehicle and/or be otherwise coupled with the rail vehicle. In some implementations, the system may detect rail vehicle events based on pre-determined rail vehicle event criteria sets. The system may include one or more sensors configured to generate output signals conveying information related to the rail vehicle. In some implementations, the system may detect rail vehicle events based on a comparison of the information conveyed by the output signals from the sensors and/or parameters determined based on the output signals to the pre-determined rail vehicle event criteria sets.
