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.

O gauge model trains are great for playing and collecting. Running on three-rail track and powered by alternating current, your model railroad will last a lifetime. Modern O Gauge Trains are mid-to-large size trains that generally run on three trails. It was the most popular scale. Visit Trainz to grab this amazing masterpiece.

Almost since the beginning of the hobby 'O' gauge has been a popular gauge to work in. Historically 'O' gauge referred to a track gauge of 1 1/4" or 32mm but is now almost universally taken to mean models built to a scale of 7mm to the foot or 1:43.54, usually rounded off to 1:43.5.

0 gauge refers to tracks that are 11⁄4 in (32 mm) apart. However, the two phrases are often also used interchangeably, albeit erroneously. When used as a narrow gauge track, 0 gauge allows scales of 1:32 representing 1,000 mm (3 ft 3⅜ in) gauge track. 1:20 representing 600 mm (1 ft 11⅝ in) narrow gauge railways.

“O Gauge” commonly refers to trains that run on 1 ¼” gauge track with 3-Rails. The trains are traditionally powered by alternating current (AC) with the center rail being one side of the power circuit and the outside rails connected to the other side of the power supply.

If you suspect the rails of your train track aren’t the correct width, causing derailments, you can check the spacing between them with either digital callipers or roller gauge. For O gauge track, the rails should be 32mm apart, for OO/HO gauge track they should be 16.5mm apart, while N, 009 and HOe must have a gauge of 9mm and Z gauge track ...
