ROUTE EXAMINING SYSTEM
A system includes a route examining system and an off-board failsafe controller. The route examining system is configured to examine a route on which a first vehicle system is moving and to generate an inspection signal based on the route examination. The inspection signal indicates a status of a segment of the route as damaged or undamaged. The off-board failsafe controller is configured to receive the inspection signal from the route examining system. Responsive to a lack of receipt of the inspection signal within a designated time period which indicates communication loss with the route examining system, the failsafe controller is configured to generate a warning signal for communication to a second vehicle system. The warning signal is generated to direct the second vehicle system to (i) avoid traveling over the route segment or (ii) travel over the route segment or another route segment at a reduced speed.
Route examining system
A system includes a route examining system on a non-propulsion-generating vehicle at a trailing end of a leading vehicle system. The route examining system examines a route on which the leading vehicle system is moving to determine whether the route is damaged. The system also includes an off-board failsafe controller that communicates with the route examining system. The off-board failsafe controller sends a warning signal to the trailing vehicle system responsive to receiving a notification signal from the route examining system indicating detection of damage to the route. The off-board failsafe controller also sends the warning signal to the trailing vehicle system responsive to losing communication with the route examining system. The warning signal directs the trailing vehicle system to automatically change movement of the trailing vehicle system responsive to the detection of damage to the route and/or the off-board failsafe controller losing communication with the route examining system.

CHARGING SYSTEM FOR ELECTRIC VEHICLES
A charging system for an electric vehicle has an elongate enclosure having a plurality of sides and an at least partially open side. The enclosure defines a hollow interior. The charging system further includes a conductor rail disposed in the hollow interior and that is accessible through the at least partially open side of the enclosure. The conductor rail may be placed in electric communication with an electrical power source and thereby may be selectively placed in electrical communication with an electrical connector of an electric vehicle. The charging system may conduct electric current from the electrical power source to an electric power supply of the electric vehicle.
Route examining system
Systems for examining a route inject one or more electrical examination signals into a conductive route from onboard a vehicle system traveling along the route, detect one or more electrical characteristics of the route based on the one or more electrical examination signals, and detect a break in conductivity of the route responsive to the one or more electrical characteristics decreasing by more than a designated drop threshold for a time period within a designated drop time period. Feature vectors may be determined for the electrical characteristics and compared to one or more patterns in order to distinguish between breaks in the conductivity of the route and other causes for changes in the electrical characteristics.

Systems and methods for braking or propelling a roaming vehicle
In one embodiment, a propulsion system includes roaming vehicles including a reaction plate installed on a bottom of each of the roaming vehicles, a surface stator matrix installed with a running surface for the roaming vehicles and including single sided linear induction motors (SSLIMs). Each of the SSLIMs include two windings installed orthogonally to one another. The propulsion system also includes motor drives configured to electrically couple to the SSLIMs via a switching panel, and a control system configured to receive information related to the roaming vehicles, receive a desired motion profile for the roaming vehicles across the surface stator matrix, determine which of the SSLIMs to activate and a performance of the SSLIMs based on the desired motion profile, the information, or some combination thereof, and send control signals to the motor drives to control the SSLIMs to produce the motion profile.
