1. A method for controlling communications linking among locomotives comprising:
- determining, during a communications linking procedure between a first locomotive and at least one of a second locomotive and a third locomotive, that the second locomotive and the third locomotive have duplicate locomotive identifiers; and
controlling an operation of the first locomotive responsive to a determination that the second locomotive and the third locomotive have duplicate locomotive identifiers.

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.

12. A method for controlling communications linking among locomotives comprising:
-
issuing a link request from a lead locomotive to a first remote locomotive desired to be controlled by the lead locomotive; receiving at the lead locomotive a first reply from the first remote locomotive responsive to the link request and a second reply from a second remote locomotive responsive to the link request, the first remote locomotive and second remote locomotive being identified in their replies by the respective predetermined identifiers; determining that the first remote locomotive and the second remote locomotive are identified by the same predetermined identifier; and limiting further communications between the lead locomotive and the first remote locomotive and second remote locomotive.

13. A method for controlling communications linking among locomotives comprising:
-
establishing a communications link between a first lead locomotive and a remote locomotive desired to be controlled by the first lead locomotive; receiving at the remote locomotive a communications link request from a second lead locomotive, the link request being encoded with a primary identifier of the second lead locomotive the same as a primary identifier of the first lead locomotive and a secondary identifier of the second lead locomotive different than a secondary identifier of the first lead locomotive; determining at the remote locomotive that the secondary identifier of the second lead locomotive encoded in the communications link request is different than the secondary identifier of the first lead locomotive; and ignoring the communications link request from the second lead locomotive.

14. A system for controlling communications linking among locomotives comprising:
-
a receiver onboard a first locomotive for receiving communication linking signals from a second locomotive and a third locomotive; and a processor coupled to the receiver for determining, during a communications linking procedure between the first locomotive and at least one of the second and third locomotives, that the second and third locomotives have duplicate locomotive identifiers and for controlling an operation of the first locomotive responsive to the second and third locomotives having duplicate locomotive identifiers. - View Dependent Claims (15, 16, 17, 18, 19, 20)

21. Computer readable media containing program instructions for controlling communications linking among locomotives, the computer readable media comprising:
-
a computer program code for determining, during a communications linking procedure between a first locomotive and at least one of a second locomotive and a third locomotive, that the second locomotive and the third locomotive have duplicate locomotive identifiers; and a computer program code for controlling an operation of the first locomotive responsive to a determination that the second locomotive and the third locomotive have duplicate locomotive identifiers.
