Clachbeg is a 7/8"n2 scale model of Clachbeg Station as it was in 1935.

7/8":1' equates to 1:13.7 and is a very large scale for modelling; 7/8"n2 represents two-foot gauge on dimensionally-correct 45 mm gauge.

My layout measures a scale 110' on each side and (including the fiddle yard) covers 9,075 scale square feet; in H0n2 it would measure all of 38.5 × 38.5 cm, in OO9 it would be 44 × 44 cm—it surely qualifies as a micro!

[it’s perhaps stretching a point, but generally “micros” are defined as “four square feet” in size, and generally they are built in H0 or OO: four square feet is equivalent to 30,336 square H0 feet or 23,226 square OO feet...]
