TT Gauge

TT scale trains, often referred to as ‘table top’ or 3mm scale, are between1:120 and 1:100 in scale, often depending on the country of manufacture. This scale is popular in Europe, particularly in Germany, though some have been produced in the UK. These trains bear similar characteristics to the N scale, and are most suitable for indoor use. TT scale trains and accessories are not as widely available as other scales.
