e/5.5mm scale

Information
has gloss	eng: 5.5mm scale is used for modelling narrow gauge railways. 12mm gauge track is used to represent to gauge prototypes. 16.5mm gauge track is used to represent gauge prototypes. History 5.5mm scale narrow gauge model railways were developed by GEM in 1963, using 12mm gauge track, which was the smallest commercially available gauge at the time (TT gauge). GEM produced kits for locomotives and rolling stock from the Ffestiniog and Talyllyn railways. Following the development of N gauge, using 9mm gauge track, the popularity of 5.5mm scale declined as modellers adopted 009 which could combine N gauge track and mechanisms with the widely supported 4mm scale.
