This page is designed to help those starting to use DCC in UK produced ready to run (RTR) locos available from the major model manufacturers in 2mm N scale. Clicking on a loco type will take you to the link which illustrates how to install a decoder in that loco. Whilst each installation uses a particular decoder there may be a number of other suitable decoders that could be used for that loco - it is the method employed in the installation that is important.
