Collection: O Scale 1:48 Military Models

1:48 is commonly known as quarter scale (as it is one-quarter of the 1:12 "standard" dollhouse scale). In 2005 Tamiya launched a new series of armored fighting vehicle (AFV) models in this scale. It is the American O scale. Architectural model scale corresponding to widely used architectural drawing scale in the U.S. Also the main Lego scale, known as minifig scale. The rather uncommon 40 mm figure scale wargames figures fit approximately into this scale.

O scale (or O gauge) is a scale commonly used for toy trains and rail transport modelling. Introduced by German toy manufacturer Märklin around 1900, by the 1930s three-rail alternating current O gauge was the most common model railroad scale in the United States and remained so until the early 1960s. 

It still remains a popular choice for those hobbyists who enjoy running trains more than they enjoy other aspects of modeling, but developments in recent years have addressed the concerns of scale model railroaders making O scale popular among fine-scale modellers who value the detail that can be achieved.

The size of O is larger than OO/HO layouts, and thus is a factor in making the decision to build an O gauge layout.
