Abstract
A communication system includes wired communication devices onboard vehicles of a vehicle system, wireless communication devices disposed onboard other vehicles, and a controller. The controller remotely controls movement of some vehicles via communication with the wired communication devices and establishes a wireless communication link with other vehicles. The controller remotely controls movement of the other vehicles via wireless communication responsive to these vehicles being connected to the vehicle system for temporarily assisting in vehicle system movement along one or more routes. These vehicles are configured to be disconnected from wired communication with the other vehicles subsequent to being connected to the vehicle system. The wireless communication link is in addition to any wireless communication links established in the vehicle system prior to the one or more second vehicles being connected to the vehicle system.
