SE scale is a designation used by some modellers to describe miniature (model) trains which run on either Gauge 1 ({{RailGauge|45mm|disp=or}}) track or O gauge ({{RailGauge|32mm|disp=or}}) track. In the SE scale, 7/8 of an inch equals one foot, which is a ratio of 1:13.7. On {{RailGauge|45mm}} gauge track this represents real life narrow-gauge railways that are {{RailGauge|2ft}} gauge, while on {{RailGauge|32mm}} gauge track this represents {{RailGauge|18in}} railways.

Modelling on a scale where 7/8 inch = 1 foot is relatively new (within the last 20 years){{Year needed|date=November 2015}} and, as a result, the majority of the modellers build from scratch.
