About
What is the LCC SIG?
The Layout Command Control Special Interest Group (LCC SIG) is an unincorporated, not-for-profit organization associated with the National Model Railroad Association. Our mission is to advocate for, promote, and support the NMRA LCC standard — fostering education, development, and adoption across the model railroad community.
Membership is open to anyone with an interest in LCC — no NMRA membership required, and participation is free of charge. The SIG holds meetings at least twice per year in virtual or hybrid format, and conducts all official business electronically.
The primary communication channel for announcements, meeting notices, and organizational information is this website at lccsig.org.
What LCC Offers
Why LCC?
Open standard
LCC is an NMRA-ratified open standard with no proprietary lock-in. Any manufacturer or hobbyist can implement it.
Peer-to-peer networking
Nodes communicate directly without a central controller, making layouts more robust and easier to expand.
Active community
An engaged group of developers, manufacturers, and hobbyists continuously improving tooling, documentation, and hardware.
Proven in the field
Deployed on layouts of all scales and complexity — from small home layouts to large modular club installations.
Governance
Leadership
The LCC SIG is governed by a five-member Board of Directors consisting of three officers and two Directors-at-Large elected by the membership.
