The National Model Railroad Association’s (NMRA) Digital Command Control (DCC) Working Group exists to foster the development of DCC. The Working Group, part of the NMRA Technical Department, is responsible for debating, creating, evolving and maintaining all standards that apply to DCC.

Further details on the Working Group, it's procedures and a current list topics may be found at www.dcc.info or through the link from the NMRA site www.NMRA.org

This e-mail list is the single official forum for discussions and decision making by the NMRA DCC Working Group,

Any NMRA member or manufacturer active in the use, development and/or promotion of DCC may become a member by applying to the Working Group Chair. Participation and membership in the NMRA Working Group is a privilege, not a right, and is obtained/maintained through active contributions to the NMRA Working Group. While technical leadership and contribution is an obvious example, having simple enthusiasm and a willingness to contribute, even if in administrative areas and not technical in nature, is sufficient. A significant DCC knowledge is a prerequisite.

Individuals or manufacturers wishing to join the Working Group may do so by contacting the NMRA (who will in turn forward them to the Working Group Chair) or any current member of the Working Group. A short recommendation as to why these persons may be of benefit to the Working Group should accompany the request. The decision on admission is made by the Working Group Chair after review and comment by the rest of the Working Group. Working Group members may also initiate discussions regarding admission of a new member.

Information on the Working Group mailing list and private web site, including documents that have not yet been adopted, is for the private use of the Working Group members only. Any persons considering joining the DCC Working Group must be willing to treat all internal WG communications made by others as confidential.
