TT scale is a model railroading scale at 1:120 scale with a Track gauge of 12 mm between the rails. It is placed between HO scale (1:87) and N scale (1:160). Its original purpose, as the name suggests, was to make a train set small enough to assemble and operate on a tabletop.

A simple H0 (1:87) scale model railroad, consisting of three interconnected modules, each 70 x 100 cm in size. It has two concentric ovals of track and a few switches to sidetracks. It makes no pretension of being a copy of "real life". Using low-cost landscaping parts, house kits and rolling stock, it was built for a total of only a few hundred dollars.
