SE scale is a designation used by some modellers to describe miniature (model) trains which run on either Gauge 1 track or O gauge track. In the SE scale, 7/8 of an inch equals one foot, which is a ratio of 1:13.7. On gauge track this represents real life narrow gauge railways that are gauge, while on gauge track this represents railways.
Modelling on a scale where 7/8 inch = 1 foot - 0 inches is relatively new (within the last 20 years) and, as a result, the majority of the modellers build from scratch.
