What is tt gauge?

TT gauge is a model railway scale with a track gauge of 12mm (0.47 inches). It was developed in the 1940s in Germany as a compromise between the larger HO scale and the smaller N scale. The name "TT" comes from the German words "Tisch" and "Tauglich," which mean "tabletop" and "suitable."

The scale ratio for TT gauge is generally 1:120, although in some countries, such as the UK, it is commonly 1:100. This means that a model train in TT scale is 120 times smaller than its real-life counterpart. The scale is commonly used for model trains, but it is also used for military models and architectural models.

TT gauge is less popular than other model railway scales and is found mainly in Europe. However, it has a loyal following of enthusiasts who enjoy the challenges of modeling in a smaller scale. As with other model railway scales, there is a wide range of TT gauge models available, including locomotives, rolling stock, and scenery.

Overall, TT gauge is a fascinating scale for model railway enthusiasts who want to create detailed and realistic layouts in a smaller space.
