Digital Command Control (DCC) is now the most common control method for earnest model railroaders, allowing multiple trains to be controlled simultaneously anywhere on the track. JMRI is an interface program that works with most brands of DCC and is very popular because it simplifies DCC programming, signaling, control, and many other aspects of running a permanent layout. It is also free and multi-platform. Instead of direct control through the DCC system, WiThrottle Lite links with JMRI or a dedicated module. This provides a universal interface to many possible combinations of technology and model railroads. As DCC evolves, JMRI is updated as needed to match current technology.

WiThrottle Lite allows you to confirm compatibility at no cost before buying the full App. Please visit our website for additional information.
