1. A system for detecting operational anomalies on a train consist or railcar comprising:
- (a) one or more communication management units mounted on one or more railcars;
(b) one or more sensors located on said one or more railcars configured to sense an operational parameter of said one or more railcars, said sensors being in communication with said one or more communication management units, wherein the one or more sensors comprise one or more sensors configured to measure accelerations of the railcar; and
(c) one or more filters configured to filter at least a portion of the accelerations,wherein said communication management units perform the functions of;
(i) collecting data regarding said one or more railcar operational parameters;
(ii) analyzing said collected data for trends or events indicative of an anomalous operational condition; and
(iii) communicating a message to a remote receiver when said trend or event is detected.
