Modeler and DCC Expert Steve Barkley provides a quick overview of Digital Command Control Systems (DCC). If you’re thinking about converting to DCC, Steve suggests constructing a sample layout so you can watch the system in action. You will also have the opportunity to become familiar and comfortable with DCC components before you convert your own layout.
This video is a very brief look at Digital Command Control Systems. If you are looking for more information regarding DCC, MRA has more videos on installing and operating the system. There are also several Track Talk Live installments with Doug Hodgdon and Steve Doyle discussing DCC.
