American OO Gauge SIG

The American OO Gauge SIG was formed in the fall of 1985 and is dedicated to the preservation and advancement of American OO gauge, which has a scale of 4mm=1ft. and a track gauge of 19 mm, essentially 0.75 in. This scale, which is slightly larger than HO scale, flourished in the 1930s through the mid-1950s. Manufacturers of American OO included many of the most famous model companies--Lionel, Mantua, Scale Craft, and j-c Models, among others. A small but devoted group of modelers continues in this scale, and wishes to help others and to foster interest in OO gauge modeling.

The primary activity of the SIG is the publication of a quarterly newsletter, The OO Road. Membership in the SIG includes a subscription to the newsletter.
