Lionel OO Gauge

Lionel introduced a range of OO models in 1938. Soon other companies followed but it did not prove popular and remained on the market only until 1942. OO gauge was quickly eclipsed by HO scale. The Lionel range of OO used ¾" (16.5 mm) track gauge, a track width that was more to scale. Lionel's OO gauge was larger and therefore incompatible with European OO gauge which uses .65 inch (19 mm) track and is basically the same as modern HO gauge.

This particular gauge was targeted at adult model train operators that were looking for more prototypical "realistic" looking models. The only locomotive ever offered was a replica of the famous NYC Hudson. This was almost an exact copy of Lionel's larger O gauge 700e Hudson from 1937.

In 1938 Lionel offered two "outfits" starting at $35 and by the next year they were offering eight sets. Lionel OO was AC powered just like their O gauge counterparts so were incompatible with other manufacturers of American OO products like Scale-craft

This scale is also sometimes referred to in print as American 00 with two zeros, but most sources back in the day and today call it American OO (pronounced "double oh").

Lionel's OO gauge was discontinued at the onset of World War II and was not produced again. Due to its short life-span Lionel OO is highly collectable today.
