How to Install a DCC Decoder

A DCC decoder, also known as a digital command controller, allows you to control your train set remotely. These sets are easy to install in most modern trains. As long as you select the appropriate decoder, installation is simple. For advice on choosing the appropriate decoder, consult the manual of your train set or ask the employee at your favorite model train store. DCC decoders vary slightly in features and some offer light or sound options.
