O Scale Model Trains

O scale provides the impressive size and presence that smaller scales cannot match. At 1:48, locomotives and rolling stock have substantial weight and visual impact. The scale spans from traditional three-rail tinplate (Lionel) to exacting two-rail scale modeling, offering options for everyone from toy train enthusiasts to prototype perfectionists.

History

O scale dates back to the early 1900s, making it one of the oldest model railroad scales. Lionel, founded in 1900, made O scale synonymous with American toy trains. Today, the scale includes both toy train traditions and serious scale modeling.
