type of the Indian Railways (IR). The first order of 200 was split evenly between NBL and Chittaranjan Locomotive Works (CLW). Apart from Indian manufacture, examples were also built in England, Scotland, Germany, Austria, the United States, Japan and Italy. By the time production ceased in 1970, 2,450 Class WG locomotives had been built. Metre gauge After World War I, an Indian Railway Standards (IRS) 2-8-2 class became the main heavy freight locomotive on the . While two versions were designed, the Class YD with a 10-ton axle load and the Class YE with a 12-ton axle load, none was built of the latter class. During World War II, many of the war-time United States Army Transportation Corps class S118 locomotives were sent to India and 33 more were ordered after the war. The post World War II Mikado design was the Class YG, of which 1,074 were built between 1949 and 1972, with nearly half of them being manufactured in India. Narrow gauges Two narrow track gauges were in use in India. The gauge was the more widely used while the gauge was used by the Darjeeling Himalayan Railway and the Scindia State Railway. Mikado type locomotives were used by the following: The Bengal Nagpur Railway used a saturated steam B class, a superheated BS class, and a BC class comprising B class locomotives that had been converted from saturated to superheated. The Barsi Light Railway used an F class of thirteen locomotives, ten built by Nasmyth, Wilson & Company between 1926 and 1929, and three built by Hunslet Engine Company in 1949. The Great Indian Peninsula Railway used a B/1 class of seven locomotives, four built by NBL in 1917, one more by NBL in 1922, and two by Nasmyth, Wilson & Company in 1926. The Scindia State Railway used sixteen locomotives of five classes, the Classes NH/1 through NH/5, built between 1914 and 1959. The standard narrow gauge 2-8-2 locomotive was the ZE class, with 65 engines built by five companies between 1928 and 1954. Nasmyth, Wilson built ten in 1928, Hanomag built sixteen in 1931, Corpet-Louvet built twelve in 1950, KraussMaffei built fifteen in 1952 and another ten in 1954, and Kawasaki Heavy Industries built ten in 1954. In 1957 and 1958, six ZD class locomotives were also built by Nippon Sharyo in Japan. Indonesia Before 1945, the Dutch East Indies Railway Administration, Staatspoorwegen (SS), introduced
