摘要： A system for determining a location of a rail vehicle based on an radio frequency (RF) signal that includes at least one processor programmed or configured to determine that a first RF communication signal transmitted by a head of train (HOT) unit of a plurality of rail vehicles is received by an end of train (EOT) unit of the plurality of rail vehicles, determine whether a second RF communication signal transmitted by the HOT unit is received by the EOT unit during a time interval after a time at which the first RF communication signal was determined to be received by the EOT unit, and determine one or more locations of the plurality of rail vehicles based on determining that the second RF communication signal transmitted by the HOT unit is not received by the EOT unit during the time interval. A method and computer program product are also disclosed.

摘要： A switch reporting device including at least one display screen, a high resolution camera, a code reader, at least one memory and one or more processors, the switch reporting device configured to determine a position of an unmonitored switch in a railway by capturing an image of one or more portions associated with the unmonitored switch, generating switch position data based on the image of one or more portions associated with the unmonitored switch, and updating a switch position record for the unmonitored switch with the switch position data. The switch reporting device includes one or more mobile computers or an EOT device for monitoring and reporting switch position data for an unmonitored switch.

摘要： In a method of braking a number of rail cars of a train travelling on a mainline track, in response to a unique braking command provided to each rail car of a first subset of rail cars, wherein each braking command includes a level or percentage of braking the brakes of the rail car are to assume, the brakes of the rail car are set to level or percentage of braking included in the unique braking command provided to the rail car. Thereafter, in response to a unique braking command provided to each rail car of a second, different subset of rail cars, the brakes of the rail car are set to level or percentage of braking included in the unique braking command provided to the rail car.

摘要： Described are a system, method, and computer program product for automatic inspection of a train including one or more locomotives and/or railcars. The method includes activating, or causing the activation of, at least one scanning drone including at least one sensor configured to obtain primary inspection data of the train. The method also includes communicating at least one set of scanning drone operating instructions configured to cause the at least one scanning drone to obtain the primary inspection data along a travel path associated with the train. The method further includes receiving the primary inspection data from the at least one sensor. In further non-limiting embodiments or aspects, the method includes activating, or causing the activation of, at least one micro drone including at least one sensor configured to obtain secondary inspection data of the train.
