Hazardous Event Alert Systems and Methods

A hazardous event alert system for a train includes a sensor, a communication device, a positioning system, and a computer. The sensor is positioned on or associated with the train and configured to sense or monitor at least one parameter or condition. The computer is programmed or configured to determine that a hazardous event occurred based at least partially on data generated by the at least one sensor, determine or receive the location or position of the at least a portion of the train from the at least one positioning system, generate a hazardous event notification based at least partially on the at least one condition and the location or position of the at least a portion of the train, and communicate the hazardous event notification to at least one of a back office system and at least one remote server associated with at least one specified entity.
