Career Operators USATC

The United States Army Transportation Corps (USATC) S100 Class is a 0-6-0 steam locomotive that was designed for switching (shunting) duties in Europe and North Africa during World War II. Several were later used on railways in Austria, Great Britain, France, Greece, Italy, Yugoslavia, Palestine, Iraq, Iran, The Netherlands, Israel and China.

The S100 is a side tank design by Col. Howard G. Hill. In 1942, the USATC ordered 382 S100s from Davenport Locomotive Works of Iowa, H. K. Porter, Inc, of Pittsburgh and Vulcan Iron Works of Wilkes-Barre. They were shipped to Great Britain in 1943 where they were stored until 1944. After D-Day, they were shipped to Continental Europe.

After the Second World War, SNCF bought 77 S100's and designated them class 030TU. Jugoslovenske železnice (Yugoslav State Railways) bought many S100's and designated them class 62. In the 1950s JŽ assembled more examples bringing the number of class 62 to 129. The Hellenic State Railways in Greece acquired 20 S100's and designated them class Δα (Delta-alpha). Österreichische Bundesbahnen in Austria acquired 10 and designated them class 989. Ferrovie dello Stato in Italy acquired four and designated them class 831.
