A data acquisition and recording system (DARS) for mobile assets that includes a data recorder. The data recorder includes a data encoder, an onboard data manager, a vehicle event detector, at least one local memory component, and a queueing repository. DARS processes data from at least one input sensor and stores a compressed record of the data at least once per second in the local memory module. DARS is designed to run in near real-time mode, storing a full record comprising five minutes of data to a remote memory module every five minutes, and in real-time mode, streaming data to the remote memory module by uploading a record of data at least once per second and up to once every tenth of a second. Remotely located users can view video, audio, and data acquired by DARS through a web browser, which provides for quicker emergency response, validate the effectiveness of repairs and rerouting, and monitor crew performance and safety.
