STANDARD THROTTLES
This category contains "tethered" throttles used to program and control all decoder functions: Train speed and direction, lighting, sounds when using sound decoders, turnouts and even animated accessories that you've installed. Some "full function" throttles are used to program your decoders as well as control the trains, while other, lower cost, "utility" type throttles can only control the trains and functions of the decoders.
WIRELESS THROTTLES
This category contains items to help you control your layout without being physically connected to the command center. Most systems use radio signals to accomplish this, however, all Digitrax Handheld throttles come factory equipped with the ability to send infrared(IR) commands with the addition of a UR90 infrared receiver. The latter is a "line-of-sight" system (like most TV remotes), usually requiring the use of more than one UR90 on a layout, unless it is very small.
