This SIG will serve as a clearing house for general information and provide mutual support about the MSS 2.0 (Modular Signal System) standard. This is a standardized method for animating model railroad signals to react to trains moving along a signaled track. MSS simulates basic Absolute Block Signal (ABS) functionality in any model railroad scale and format, though it's especially well-suited for a modular model railroad.  Additional information about MSS can be obtained at the MSS web site.

The SIG will be using an IO groups as a forum. (modularsignalsystemstandard [at]  There will be no printed publications.
