SE scale is a designation used by a growing number of modellers to describe miniature (model) 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 railroads in real life.

Modelling in a scale where 7/8" = 1'- 0" is relatively new (within the last 20 years) and, as a result, the majority of the modellers build from scratch

Scratch building

Scratch building is the process of building a scale model "from scratch", ie. from raw materials, rather than building it from a commercial kit, kitbashing or buying it pre-assembled....
