Abstract: A signal communication system is provided that may include signaling lamp assembly, a receiver device, and a communication device. The signaling lamp assembly may include a lamp generating light indicative of a status of a wayside device The lamp may generate the light responsive to receiving an activation signal. The receiver may receive timing signals from one or more remote signal sources and output a time indication based on the timing signals that are received. The receiver may output the time indication responsive to the lamp receiving the activation signal. The communication device may send a status signal responsive to the lamp receiving the activation signal, the status signal indicating the status of the wayside device and the time indication.

Abstract: A system and method includes a first control system having one or more processors onboard a lead vehicle of a vehicle system that includes the lead vehicle and a remote vehicle. The second control system automatically restricts movement of the vehicle system based on a location of the vehicle system. The processors detect a signal instance of an operator actuating an input device, and communicate a vehicle information request message to the second control system. The second control system communicates a list of vehicle identifiers, that includes a vehicle identifier associated with the remote vehicle, to the processors. The processors communicate a wireless linking message, including a request to establish a communication link, to the remote vehicle based on the vehicle identifier associated with the remote vehicle.

Abstract: A system includes one or more processors, a communication device, and a positive train control (PTC) system. The one or more processors and communication device are onboard a lead vehicle of a vehicle system that includes the lead vehicle and a first remote vehicle. The PTC system is configured to restrict movement of the vehicle system based on a location of the vehicle system. The PTC system communicates a list of vehicle identifiers to the one or more processors. The communication device communicates a wireless linking message, which includes a vehicle identifier associated with the first remote vehicle, to the first remote vehicle. The communication device establishes a communication link between the lead vehicle and the first remote vehicle responsive to receipt of the wireless linking message at the first remote vehicle. The one or more processors remotely control movement of the first remote vehicle via the communication link.

Abstract: A method and a communication system includes establishing a communication link between a first vehicle and an off-board database. The first vehicle and the off-board database are communicatively linked via a first communication system. A message from a second vehicle may be received via the off-board database. The second vehicle and the off-board database are communicatively coupled via a second communication system. A response may be communicated from the first vehicle to the second vehicle via the off-board database.
