The Prima Diesel-electric locomotives are a class of medium and heavy, four- and six-axle, passenger and freight mainline locomotives.〔(Alstom Launches Prima Locomotive Range : International Railway Journal )〕 They have been built both to standard and broad gauges, and find use in the Middle East, Europe and North America. Alstom is the primary designer in cooperation with both General Motors (now EMD) and Siemens. ==History== Initially the Prima locomotives were electric only, with the technology demonstrator and test platform being built in 2002〔(Prima platform: electrical locomotives. Railcolor.net )〕 in Belfort France by Alstom. Next came the Prima 6000 technology demonstrator; this too was an electric locomotive, with 6000 kW of power and primarily intended to test and demonstrate multi-voltage operations for European cross-border operations.〔(Alstom Prima 6000 Demonstrator: Introduction. Railcolor.net )〕 Orders for the Prima electrics came, mostly from SNCF. A series of diesel locomotives also associated with the Prima name were also built. These were the General Motors (GM)-engined machines built by Alstom at its Spanish plant in Valencia, and Ruston-engined locomotives built in Belfort, France. The Valencia plant was sold to Vossloh in 2004. Locomotives continued to be built there using EMD engines and electrical transmission systems - including almost total rebuilds of the RENFE 333 class. Vossloh changed the names of the products produced there to the "Vossloh Euro" platform〔( Diesel heavy haul across Europe ) ''eurotrib.com''〕 (see Vossloh Euro locomotives) and the end came of the association of the Valencia plant with the Prima name.〔(Brief description of all Primas except BB75000 : Railcolor.net )〕 Also produced in the 1990s were Prima diesels countries outside Europe. The DE32C was produced for Chemins de Fer Syriens in Syria, and Sri Lanka received 10 locomotives which it designated M9 class. A DE43C model was exported to Iran (AD43C〔(Alstom AD43C : Rail.lu )〕). Nevertheless the Euro 3000 and Euro 4000 products produced at Vossloh España continue to show similarities with the earlier Prima products〔—such as the centrally located driver position with radially located controls, the single drivers window, and general body shape and design of the rigid body shell. Alstom and Siemens collaborated to produce the BB 75000 diesel, which has received orders for at least 400 locomotives from SNCF with a possibility of 100 more. A Siemens/Alstom BB 75000 mock-up was unveiled on 25 March 2004,〔(SNCF Fret BB 37000: Introduction. Railcolor.net )〕 The first locomotive was produced in 2006. In 2008 Alstom unveiled the 'Prima II' platform;〔(Prima II unveiled by Alstom 23 May 2008 Railway Gazette )〕 diesel versions are to be offered,〔(ALSTOM Transport ), 25 February 2009, via ''conferinte.club-feroviar.ro''〕 so it is expected that further models of the Prima diesel locomotive family will appear. 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「Alstom Prima diesel locomotives」の詳細全文を読む スポンサード リンク
