North Coast Engineering has been manufacturing Digital Command Control Products on an OEM basis since 1993. Originally they offered only chip sets and software which enabled other DCC manufacturers to build DCC systems. Today, NCE has to grown into a full time electronic design and manufacturing firm devoted entirely to the development and sale of products for the control of model railroads.
NCE developed the hardware and software for the Wangrow System One, an early DCC system. NCE began selling their own system when Wangrow passed on their proposed upgrade to the System One. In fact, the NCE branded system shipped with the System One manual as it was the only manual available at first.
