A wireless system uses a direct UHF radio frequency (RF) signal to control
electric trains and train accessories. A controller, such as a handheld
unit used by the toy train operator, accepts control commands and
transmits encoded control data over a high frequency radio link directly
to a receiver, on the toy train or train accessory, which decodes the
commands and controls the toy train or toy train accessory functions with
either unidirectional or bidirectional communication between the
controller and the model train or train accessory. One controller has the
ability to control many trains and other model train layout components
such as signals and track switches even while other train operators are
operating their trains on the same electric train track layout.
