A system includes a router transceiver unit that is configured to be disposed on-board a vehicle system. The vehicle system may have at least a source vehicle and a separate linked vehicle that are mechanically linked with each other to travel together along a route and that are communicatively linked with each other through a system network of the vehicle system. The router transceiver unit is configured to be communicatively coupled to a requesting operational component of the source vehicle and the system network. The router transceiver unit is also configured to receive a local data packet from the requesting operational component that is directed toward a target operational component of the linked vehicle. The router transceiver unit includes an encapsulation module that is configured to transform the local data packet into an in-tunnel data packet, where the local and in-tunnel data packets have different packet formats.
