A system for monitoring railcar and tram consist operational parameters and detecting anomalies in the operation and condition thereof using sensors to feed data to a distributive complex event processing engine.

A wireless sensor device includes: an energy harvester configured to convert vibration generated from a broadband vibration source into electricity, an elastic member arranged to receive the vibration and a communication unit fixed by the elastic member, supplied with the converted electricity from the energy harvester, and configured to transmit sensing information obtained by sensing a measurement target. The elastic member operates as a mechanical filter configured to limit a frequency range and an acceleration magnitude of the vibration to be transferred to the communication unit for stabilizing the performance of the communication unit, and the communication unit is arranged to receive vibration passing through the elastic member.

Methods and systems for monitoring and detecting various events or anomalies of interest on or along an object of interest, such as a transportation path, road, or railway, are presented. Data regarding the detected events can be collected near its source and transmitted to a data collection or processing object for analysis or storage. These events may include, but not limited to, rock falls, wheel or tire flat spots, or other acoustic or vibration generating events at or near the object of interest.

An on-board monitoring system for bogies or railroad trucks monitors components over time. The system is modular comprising a first modular device for mounting on the vehicle next to a component to be monitored and passing data on to one or more further modular devices. Focussed data acquisition and ongoing monitoring of a component becomes possible. Data transmission and analysis is also considered.

A system that can automatically control the emissions of each locomotive in a consist to reduce overall train emissions. An emissions module determines the amount of emissions emitted by a train. An emissions control module commands the locomotive, via the train control system, to operate in a predetermined state to achieve a particular amount of emissions. A location module can track the location of the locomotive of the train relative geographic locations having emission regulations so that the emissions control module can command appropriate changes in the locomotive to reduce emissions.

A system that can automatically measure, track, and/or report train emissions for complying with geographic environmental restrictions. An emissions module determines the amount of emissions emitted by a train over time. A location module tracks the location of the locomotive of the train relative geographic locations having emission regulations. A compliance module records the amount of emissions emitted by the train in the geographic location.
