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.
