The C38 class was a class of steam locomotives built for the New South Wales Government Railways in Australia. Built between January 1943 and November 1949, the 30 locomotives in the class were designed to haul express trains. They were the only New South Wales locomotives to use the popular Pacific 4-6-2 wheel arrangement and were the last steam locomotives built for passenger train operation, all subsequent deliveries being specifically for freight haulage.〔"Some Notes on the C38 Class 4-6-2 Locomotive" Young, Harold ''Australian Railway Historical Society Bulletin'' December 2003 pp443-463〕 ==Design== The 38 class were first conceived in the 1930s being heavily influenced by American and other streamlined locomotives of the time.〔The C38 Class, John. B. Thompson pp3 'Why the 38's'〕 The NSWGR needed a locomotive to eliminate the complications of doubleheading required on a number of fast interstate passenger trains. The design team was headed by Harold Young, the Chief Mechanical Engineer of the NSWGR. The conditions of trackwork with frequent sharp curvature to be traversed at high speed would require six-coupled driving wheels in a 'Pacific' 4-6-2 configuration. Maintenance considerations suggested a two-cylinder simple steam locomotive. The design was carried out by the NSWGR Locomotive Section of the Design Office and incorporated the latest developments in locomotive design from Australia and overseas. The incorporation of as many Australian manufactured components as possible was a requirement at the design stage. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「New South Wales C38 class locomotive」の詳細全文を読む スポンサード リンク
