SE scale
SE scale is a designation used by a growing number of modellers to describe miniature trains which run on either Gauge 1 track or O gauge track. In SE scale, 7/8ths 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 in a scale where 7/8" = 1'- 0" is relatively new and, as a result, the majority of the modellers build from scratch.
