ScaleSeven (S7) is a set of finescale model railway standards for 1:43.5 (7 mm scale) using true-to-prototype track and wheel standards. It is principally used to model British standard gauge (4 ft 8+12 in (1,435 mm)), Irish Broad Gauge (5 ft 3 in (1,600 mm)), or Great Western broad gauge (7 ft (2,134 mm)).
