Popular 'garden gauges' are '0' gauge, '1' gauge and 2½" gauge (ridable). Usual club track gauges are 3½", 5" and 7¼", and 4¾" and 7½" in North America. Larger miniature railway gauges such as 10¼" and 15" gauge are more common in zoo and park settings or as public passenger-hauling lines such as the Romney, Hythe & Dymchurch Railway. Various gauges have existed over time. 3½" and 5" gauge were proposed in 1898 as standard model gauges, although 5" gauge only became popular after the Second World War, along with 7¼" gauge.
