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 also have a new, modular switching layout that also goes to some shows.
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).
