ABSTRACT:
A system is provided for establishing a wireless-based communication link between a lead locomotive and a remote locomotive. A user on the lead locomotive is prompted to input a railroad and number identifier of the remote locomotive. A link command signal is transmitted from the lead locomotive, based on a predetermined number identifier of the lead locomotive, and the inputted railroad and number identifier. A second processor on the remote locomotive respectively compares the predetermined number identifier of the lead locomotive, the inputted railroad and number identifier of the lead locomotive, with an inputted number identifier of the lead locomotive, a predetermined railroad and a predetermined number identifier of the remote locomotive. A link reply signal, is transmitted from the remote locomotive, based on the comparison performed by the second processor, to establish the communication link. Additionally, a method is provided for establishing the wireless-based communication link.
