About Us

DCCWiki is an encyclopedia for sharing information about Digital Command Control (DCC) as defined by NMRA used in railroad modelling. We also started a new section for the new Layout Command Control (LCC) standard from the NMRA which can be used to enhance your layout with signalling, accessory control, and other features.

Check out our brand new Forums. Get help with DCC topics or get help adding or editing DCCWiki articles. Many articles found on DCCWiki started as small articles people have created to answer common questions and have since been expanded into full articles.
