What is DCC?

FUN button DCC stands for Digital Command Control. It is a way of having power continuiously on the track. This way, rolling stock can have lights and sound even when they are standing still.

Data is sent over the track from the base unit to a decoder (receiver) located inside the locomotive or car, telling it what to do when.
