Abstract: This disclosure relates to a system configured to detect rail vehicle events. Some or all of the system may be installed in a rail vehicle and/or be otherwise coupled with the rail vehicle. In some implementations, the system may detect rail vehicle events based on pre-determined rail vehicle event criteria sets. The system may include one or more sensors configured to generate output signals conveying information related to the rail vehicle. In some implementations, the system may detect rail vehicle events based on a comparison of the information conveyed by the output signals from the sensors and/or parameters determined based on the output signals to the pre-determined rail vehicle event criteria sets.

Abstract: A railway safety critical application system substitutes commercial off-the-shelf (COTS) hardware and/or software for railway-domain specific product components, yet is validated to conform to railway safety critical system failure-free standards. The safety critical system uses a pair of tasks executed on a controller of a COTS personal computer or within a virtual environment with asymmetric communications capability. Both tasks receive and verify safety critical systems input message data and security code integrity and separately generate output data responsive to the input message. The first task has sole capability to send complete safety critical system output messages, but only the second task has the capability of generating the output security code. A failure of any of systems hardware, software or processing capability results failure to transmit a safety critical system output message or an output message that cannot be verified by other safety critical systems.

Abstract: A system for controlling locomotive compressors in a multiple locomotive consist to optimize compressor life, cold weather operation, and maintenance schedules. Each compressor is associated with a controller than can communicate via an interface to a network with the corresponding controllers of the other compressors that are also interfaced to the network. A lead compressor controller may then issue commands to the other compressor controller to more efficiently restore pressure to the system, to implement improved usage schedules, or to manage maintenance intervals to maximize usage of each compressor during periodic maintenance intervals.

Abstract: A sensing system includes a leading sensor, a trailing sensor, and a route examining unit. The leading sensor is onboard a first vehicle of a vehicle system that is traveling along a route. The leading sensor measures first characteristics of the route as the vehicle system moves along the route. The trailing sensor is disposed onboard a second vehicle of the vehicle system. The trailing sensor measures second characteristics of the route as the vehicle system moves along the route. The route examining unit is disposed onboard the vehicle system and receives the first characteristics of the route and the second characteristics of the route to compare the first characteristics with the second characteristics. The route examining unit also identifies a segment of the route as being damaged based on a comparison of the first characteristics with the second characteristics.

Abstract: A vehicle includes running wheels traveling on traveling road surfaces of tracks; a pair of position detection parts disposed at an interval in a width direction that output signals by detecting a distance from measured objects; a control unit controlling the amount of steering of the running wheels according to the signals from the position detection parts; and a steering mechanism steering the running wheels via the control unit. Each of the position detection parts outputs a signal having characteristics such that the output increases as the distance from the measured objects increases while an output change ratio is decreased in a range wherein the distance from the measured objects is not less than a predetermined value, and is configured such that, when the distance between one position detection part and the measured object is decreased, the distance between the other position detection part and the measured object is increased.

Abstract: A train control system includes independent virtual in-train forces modeling engines onboard each of a plurality of locomotives in a train and a data acquisition hub configured to acquire signals from sensors, wherein the signals are indicative of real-time force and displacement measurement data from each of draft gears and couplers interconnecting each locomotive with another locomotive or with non-powered rail cars, acquire synchronized messages transmitted from offboard the train or from other locomotives of the train over a range of frequencies used by voice radios on the train for communicating between the locomotives, wherein the synchronized messages include real-time information on starting the train, stopping the train, and the next two speed limits for the train, and acquire heuristic data indicating the locomotive's motion during a predetermined period of time. An energy management system adjusts throttle requests, dynamic braking requests, and pneumatic braking requests for the locomotives based at least in part on a respective one of the virtual in-train forces models.
