A system includes one or more processors configured to communicatively link a first operator control unit (OCU) disposed off-board a vehicle system with a vehicle control system (VCS) disposed onboard the vehicle system. The vehicle system is formed from first and second vehicles. The VCS is configured to remotely control movement of the second vehicle from the first vehicle, wherein the one or more processors configured to receive a control signal communicated from the first OCU to a communication device that is onboard the first vehicle. The control signal dictates a change in movement operational setting of the second vehicle. The one or more processors configured to direct the communication device to communicate the control signal from the first vehicle to the second vehicle via the VCS, wherein movement of the second vehicle is automatically changed responsive to communicating the control signal from the first vehicle to the second vehicle.
