The 48 Class are a class of diesel locomotives built by AE Goodwin, Auburn for the New South Wales Government Railways between 1959 and 1970. Once the most ubiquitous locomotive in New South Wales (and Australia), they are based on Alco frames and prime movers, using General Electric (later Associated Electrical Industries) electrical equipment. The South Australian Railways 830 and Silverton Rail 48s classes are of a very similar design. ==History== The 48 Class were ordered to commence the conversion of branch lines to diesel traction with the first entering service in September 1959. Further orders saw 165 in service by October 1970. There were four versions: *Mark 1: 4801 – 4845 *Mark 2: 4846 – 4885 *Mark 3: 4886 - 48125 *Mark 4: 48126 – 48165 The Mark 1's and Mark 2's can be distinguished from the others by their fuel tank, which incorporates the brake reservoir tanks on either side. As well as branch lines they operated both main line and metropolitan services on every line in the state. Aside from a couple written off after accidents in the mid-1980s, withdrawals didn't commence in earnest until August 1994.〔"48 Class" ''Railway Digest'' November 1994 page 32〕 In December 1994 the first Mark 1s were sold.〔"State Rail's Locomotive Auction Results" ''Railway Digest'' January 1995 page 36〕 By June 1997 FreightCorp's fleet was down to 120 units.〔"Motive Power Review - The 48 Class" ''Railway Digest'' June 1997 page 42〕 Others have been withdrawn since and as at January 2014, 66 remained in service primarily with Pacific National. GrainCorp, Greentrains, Junee Railway Workshop and RailCorp also operate some.〔(48 Class ) Railpage〕〔(48 Class (Graincorp) ) Railpage〕〔(48s Class ) Railpage〕〔(48 Class ) Vicsig〕 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 48 class locomotive」の詳細全文を読む スポンサード リンク
