OO Gauge Size, British Railways & Compatibility

Understand 1:76 scale, 16.5 mm track, and layout choices

OO Scale is 1:76 scale and commonly runs on 16.5 mm gauge track. That track gauge is also used by HO, but OO models are larger in proportion and typically represent British railway equipment. OO Gauge is especially popular for layouts inspired by railways in the United Kingdom.

British Railway Eras & Operations

Build a steam-era branch line, a goods yard, a passenger station, or a modern diesel railway. Compare liveries, operators, locomotive classes, and coach or wagon styles to assemble a consistent train.

Track & Compatibility Checks

Before buying, confirm the model’s minimum curve radius, couplers, power requirements, and DC or DCC features. OO and HO share nominal track gauge, but not every locomotive or accessory will be interchangeable in every setup.
