What is TT?

TT Scale is 3mm to the foot and or 1/120th the size of the real thing. It is particularly popular in Europe and is highly regarded as a scale that is both easy on the eye and practical to model.

Hornby revived the TT:120 Scale in Summer 2023 and it proved very popular from the outset. With their range of train sets, it couldn’t be any easier to get started and with iconic locomotives such as Flying Scotsman, Mallard and the HST, you can easily build a fantastic layout in no time at all.
