An event recorder includes an outer case, and a first memory module including a first amount of data storage capacity contained within the outer case. The first memory module is configured to receive and store multiple types of data including at least two of: video data; audio data; locomotive data indicative of one or more locomotive operating parameters, locomotive control signals, and locomotive performance characteristics; engine operating parameter data; exhaust characteristics data; electrical data; and positive train control data. A controller contained within the outer case may be configured to associate a universal time stamp with each of the multiple types of data stored in the first memory module. An inner, crash-hardened case may be contained within the outer case, containing a second memory module including a second amount of data storage capacity that is smaller than the first amount. The controller may be further configured to periodically transfer a portion of the time-stamped data stored in the first memory module to the second memory module.
