2 ft and 600 mm gauge railways

In preparation for World War II, the French Maginot Line and Alpine Line also used 600 mm (1 ft 11+5⁄8 in) gauge railways for supply routes to the fixed border defenses.

Australia has over 4,000 kilometres (2,500 mi) of 2 ft (610 mm) gauge sugar cane railway networks in the coastal areas of Queensland, which carry more than 30 million tonnes of sugar cane a year.

Many 2 ft (610 mm) gauge and 600 mm (1 ft 11+5⁄8 in) gauge railways are used in amusement parks and theme parks worldwide.

The interchange of rolling stock between these similar track gauges occasionally occurred; for example, the South African Class NG15 2-8-2 locomotives started their career on the 600 mm (1 ft 11+5⁄8 in) gauge.

The Otavi Mining and Railway Company in South West Africa (now Namibia) were transferred to the 2 ft gauge railways in South Africa and currently some surviving locomotives reside in Wales on the 1 ft 11+1⁄2 in (597 mm) gauge Welsh Highland Railway and the 1 ft 11+3⁄4 in (603 mm) gauge Brecon Mountain Railway.
