Abstract

A transmitter for remotely controlling a locomotive entity. The transmitter has a control entity capable of acquiring a plurality of states, including a linked state. The transmitter also has an interface in communication with the control entity for receiving an identifier of the locomotive entity via a communication link. The transmitter also has a proximity detector having a detection field, the proximity detector being in communication with the control entity to enable the control entity to switch to the linked state at least when the locomotive entity is in the detection field.
