A control system is for a railway yard with railroad tracks. The control system may include RCLs and sets of railcars on the railroad tracks. The control system may include railyard sensors configured to generate railyard sensor data of the railroad tracks, and a server in communication with the RCLs and the railyard sensors. The server may be configured to generate a database associated with the sets of railcars based upon the railyard sensor data. The database may have, for each railcar, a railcar type value, a railcar logo image, and a vehicle classification value. The server may be configured to selectively control the RCLs to position the sets of railcars within the railroad tracks based upon the railyard sensor data.

A control system includes a controller configured to control communication between or among plural vehicle devices that control operation of a vehicle via a network that communicatively couples the vehicle devices. The controller also is configured to control the communication using a data distribution service (DDS) and with the network operating as a time sensitive network (TSN). The controller is configured to direct a first set of the vehicle devices to communicate using time sensitive communications, a different, second set of the vehicle devices to communicate using best effort communications, and a different, third set of the vehicle devices to communicate using rate constrained communications.

A first device is provided. The first device includes a first processing unit, wherein the first processing unit is adapted to determine a first status of a first connection between the first processing unit of the first device and a corresponding first processing unit of a second device; and a second processing unit, wherein the second processing unit is adapted to determine a second status of a second connection between the second processing unit of the first device and a corresponding second processing unit of the second device. The first processing unit is further adapted to: receive the second status of the second connection from the second processing unit of the first device over a path between the first processing unit of the first device and the second processing unit of the first device; and determine one or more actions to take with respect to a machine associated with the first device based on one or both of the first status and the second status.

A system and method provide seamless control switchover through an input coupled to a power line and a safety apparatus that actuates if the input remains de-energized for a first time interval. Each of a plurality of subsystems has a control unit that controls a power source to energize the power line and is capable of transitioning between master and slave states. A first switch or second and third switches in series couple the power source to the power line. The first switch is closed during master state operation. The second switch is closed during slave operation and the third switch is open if any subsystem control unit is in master state. The system is configured to open or close the first switch, the second switch, or the third switch responsive to a transition of a control unit to or from master state within the first time interval.
