The PSA today being that <strong>American OO models do not run on HO gauge track<\/strong>, they run on proper OO gauge track. <strong>Since the beginning of American OO in 1930, it has always been 1\/76 scale models running on 19MM (3\/4\u201d) gauge track<\/strong>. Models were manufactured in large commercial quantities for this scale and gauge combination by Nason, Scale-Craft, and Lionel (among others), with interest peaking just before WWII.<\/p>\n\n\n\n<p>To see American OO described as it was in the sidebar is disappointing, but not really a surprise. People today often assume it was an American version of HO\/OO like the British do, OO scale models running on HO gauge track. But no. The illustration below, from the October, 1939 issue of <em>Miniature Railroading<\/em>, makes the comparison of scale and gauge very clear. The early advocates of American OO were clear in a desire to match 4MM scale models with a track that was the correct gauge, improving on the early British OO (which is still produced with OO bodies riding on HO gauge track).<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><img data-recalc-dims=\"1\" loading=\"lazy\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/americanootoday.com\/wp-content\/uploads\/2021\/06\/HO-OO-Min-RR-10-39.jpg?resize=640%2C241&#038;ssl=1\" alt=\"\" class=\"wp-image-893\" width=\"640\" height=\"241\" srcset=\"https:\/\/i0.wp.com\/americanootoday.com\/wp-content\/uploads\/2021\/06\/HO-OO-Min-RR-10-39.jpg?w=400&amp;ssl=1 400w, https:\/\/i0.wp.com\/americanootoday.com\/wp-content\/uploads\/2021\/06\/HO-OO-Min-RR-10-39.jpg?resize=300%2C113&amp;ssl=1 300w\" sizes=\"auto, (max-width: 640px) 100vw, 640px\" \/><\/figure>\n\n\n\n<p>This PSA also serves as a reminder for all of us to spread the word on exactly what American OO is.
