    Abstract: A communication system includes a first wireless communication device disposed onboard a vehicle system having two or more propulsion-generating vehicles that are mechanically interconnected with each other. The communication system also includes a controller configured to be disposed onboard the vehicle system and operatively connected with the first wireless communication device in order to control operations of the device. The controller is configured to direct the first wireless communication device to switch between operating in an off-board communication mode and an onboard communication mode. When the first wireless communication device is operating in the off-board communication mode, the device is configured to receive remote data signals from a location that is disposed off-board of the vehicle system. When the first wireless communication device is operating in the onboard communication mode, the device is configured to communicate local data signals between the propulsion-generating vehicles of the vehicle system.

    Abstract: A system includes first and second application devices, a control unit, and at least one processor. The first and second application devices are configured to be at least one of conductively or inductively coupled with one of the conductive tracks. The control unit is configured to control the first and second application devices in order to electrically inject a first examination signal into the conductive tracks via the first application device and a second examination signal into the conductive tracks via the second application device. The at least one processor is configured to monitor one or more electrical characteristics of the first and second conductive tracks in response to the first and second examination signals being injected into the conductive tracks; and to identify a type of fault based upon the one or more electrical characteristics of the first and second conductive tracks.

    Abstract: A system (for controlling a vehicle system along a route) includes a route geometry sensor, a speed sensor, and a controller. The route geometry sensor monitors a route curve profile for a segment of the route. The speed sensor monitors a speed of the vehicle system. The controller identifies a characteristic frequency associated with the vehicle system. The controller determines a periodic driving force exerted on the vehicle system from the route based on the route curve profile and the speed of the vehicle system. The controller analyzes the periodic driving force with the characteristic frequency to determine an excitation rate. Responsive to the excitation rate exceeding a designated threshold, the controller designates tractive efforts or braking efforts for implementation by the vehicle system to change the speed of the vehicle system such that the excitation rate falls below the threshold.

    Abstract: A method for acoustically examining a route includes sensing passively excited residual sounds of a vehicle system during travel over a route, examining the passively excited residual sounds to identify one or more changes of interest in the passively excited residual sounds, and identifying a section of the route as being damaged responsive to the one or more changes of interest in the passively excited residual sounds that are identified.

    Abstract: A route examining system includes first and second application devices, a control unit, first and second detection units, and an identification unit. The first and second application devices are disposed onboard a vehicle traveling along a route having conductive tracks. The control unit controls injection of a first examination signal into the conductive tracks via the first application device and injection of a second examination signal into the conductive tracks via the second application device. The first and second detection units monitor electrical characteristics of the route in response to the first and second examination signals being injected into the conductive tracks. The identification unit examines the electrical characteristics of the conductive tracks in order to determine whether a section of the route is potentially damaged based on the electrical characteristics.
