The History of TT Gauge
The TT gauge, which stands for "Table Top," emerged in the 1940s as a revolutionary concept in model railroading. Hal Joyce of H.P. Products in the United States developed this scale to bridge the gap between the larger HO gauge and the smaller N gauge. The 1:120 scale of TT gauge offered modelers a perfect compromise, allowing for detailed models that didn't require excessive space.
Initially popular in the United States, TT gauge saw a decline in the 1960s and 70s. However, it found new life in Europe, particularly in former Eastern Bloc countries. Today, TT gauge is experiencing a renaissance, with manufacturers like Hornby, Peco, and Graham Farish expanding their offerings in this scale.
