Abstract: A method for controlling first (14/12A) and second (12B) locomotives of a railroad train (8), the first (14/12A) and the second (12B) locomotives separated by at least one railcar (20). The method comprises determining a location of the first locomotive (14/12A) and a location of the second locomotive (12B), determining an operating condition of the first locomotive (14/12A) and an operating condition of the second locomotive (12B), determining a first control aspect of the first locomotive (14/12A) responsive to the operating condition and the location of the first locomotive (14/12A), determining a second control aspect of the second locomotive (12B) responsive to the operating condition and the location of the second locomotive (12B), and controlling the first (14/12A) and the second (12B) locomotives according to the first control aspect and the second control aspect, respectively.

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.

Abstract: A method for controlling communications linking among locomotives includes determining, during a communications linking procedure between a first locomotive (e.g., 12, 36) and at least one of a second locomotive (e.g., 14, 32) and a third locomotive (e.g., 16, 38), that the second locomotive and the third locomotive have duplicate locomotive identifiers. The method further includes controlling an operation of the first locomotive responsive to a determination that the second locomotive and the third locomotive have duplicate locomotive identifiers.
