A new way of controlling model railroads

The OpenLCB project is developing an easy but sophisticated network for model railroad control using today's technology.

From small ... to big ... to huge,

OpenLCBTM will help you do what you want to do most: run your railroad.

It is Easy to use: Whether you want to do simple setup by just pushing buttons on boards, or use a full-featured configuration tool, OpenLCB makes setup easy.

It protects your investment: From your first two boards through huge modular layouts, OpenLCB equipment will grow with your railroad, and you can still connect and use your legacy equipment.

It is simple to expand: OpenLCB equipment can be added without worrying about ID conflicts, without keeping track of complicated address assignments, and never being forced to go back and reconfigure equipment – all while working with your existing model-railroad controls.



The OpenLCB group did a day's worth of demonstrations of OpenLCB at the NMRA 2010 convention in Milwaukee. We've got a page of movies, photos and diagrams for those who couldn't get there.

What we're doing:

OpenLCB is being developed through an open, community based process. You can follow our documents as they develop, check out our prototype code, and if you want to take part.

Welcome to the project! We all benefit by working on this together. Questions and comment can be directed to the egroup: OpenLCB

Other Efforts

CBUS is a CAN-based layout control bus being developed by MERG.

The NMRA has an effort to create an “NMRAnet” layout control bus standard. OpenLCB is being proposed for that.

Past discussions have taken place on the NMRANETWG and MRRLCB Yahoo groups.
