Abstract
A method and system for coordinating the transfer of control of a remotely controlled locomotive is disclosed. The generation and assignment of command authority between remote controllers is accomplished by signal transfer between the remote controllers themselves, in contrast to a system that requires the use of a slave controller to determine, assign, and/or transfer command authority. In an exemplary embodiment, a transfer request is transmitted from a first control unit to a second control unit, the first control unit initially having a command authority. An acceptance of the transfer request is transmitted from the second control unit to the first control unit, and a confirmation of transfer is transmitted from the first control unit to the second control unit. Following the transmission of the confirmation of transfer from the first control unit to the second control unit, the second control unit assumes the command authority from the first control unit.
