3mm finescale

When TT gauge model railways were developed for British prototypes, in order to fit the small British prototypes, the scale was enlarged but without altering the 12mm gauge. The result, British TT gauge, is too narrow. Thus two finescale standards were developed. By far the more common of these is 14.2mm gauge track, which is accurate. Some modellers choose to use slightly narrower 13.5mm track due to the necessary oversize motion of outside-cylindered steam locomotives.

The 3mm Society caters for all modellers of 3mm scale.
