Abstract: A method for controllably linking propulsion units in a vehicle consist includes transmitting a linking signal having an identity of a lead propulsion unit. A remote propulsion unit is remotely controlled by the lead unit when the identity matches a designated identity stored onboard the remote unit. A de-linking signal is transmitted from the lead unit when the lead unit is to be decoupled from the vehicle consist. The de-linking signal includes a replacement identity of a replacement propulsion unit. A replacement linking signal is transmitted from a second lead unit. The remote propulsion unit allows the second lead propulsion unit to remotely control the operations of the remote propulsion unit when replacement identity stored onboard the remote propulsion unit matches an identity that is communicated in the replacement linking signal.

Abstract: A data communication system for a rail vehicle includes a data reading device and a processing module. The data reading device is disposed on the rail vehicle and is configured to at least one of electromagnetically interrogate or optically read identification data that is visually presented on a first operator control unit. The first operator control unit is configured to remotely control operations of one or more powered units of a rail vehicle consist when the operator control unit is disposed outside of the one or more powered units. The processing module is disposed on the rail vehicle and is communicatively coupled with the data reading device. The processing module receives the identification data from the data reading device and uses the identification data to identify the first operator control unit and allow the first operator control unit to remotely control operations of the one or more powered units.
