As the most popular model train scale in the United Kingdom, OO Scale (or OO Gauge) uses 16.5mm gauge track—the same as HO scale—while maintaining a 1:76 scale to better fit motors and electrical components within British-outline locomotives and rolling stock. This unique combination makes OO Scale ideal for detailed and space-efficient UK railway layouts.
For building and expanding layouts, OO Scale train track includes flexible track, sectional systems, and points designed for smooth and reliable operation. These track options make it easier to create realistic railway scenes with consistent performance.
Leading manufacturers such as Hornby and Peco produce a wide range of OO Scale locomotives, rolling stock, and accessories. Browse OO Scale model trains for sale to find equipment suited to your layout.
