O Scale is one of the oldest modeling scales, having been introduced by the German company Marklin around 1900. 

The club has a 4’x8′ O Scale display for use at shows. We are also looking at building or acquiring a larger O scale layout for our new clubhouse.

O Scale is 1:48 to 1:43.5 and the distance between the rails (gauge) is 30 mm (1.181 in) – 33 mm (1.3 in).
