The RENFE Class 352 (formerly the T-2000) was a class of twin engined four axle diesel-hydraulic locomotives built by Krauss-Maffei, designed solely for passenger traffic; in particular they were responsible for towing Andalusian Talgo III trains. The class were very successful, heralding a new era of passenger trains in Spain They were delivered in 1964 and 1965, and were fully withdrawn during the 1990s == Background and design == With the Talgo II coaches having proved successful, and a new class of coaches—the Talgo III being introduced in the early 1960s—a new type of express locomotive was required to pull them. On 28 May 1962, the Board of Directors of RENFE placed an order for the locomotives needed, and the 2000-T series is born. Unlike the fixed formation Talgo II trains, the Talgo III was to have a locomotive which was separable from the coaches. Five locomotives were initially built by Krauss-Maffei, who gave the locomotives the internal designation ML 2400; in Spain they are placed in the class 2000-T. The Krauss-Maffei design is chosen since no other manufacturer offers similar power in the reduced height, and low centre of gravity that matches the Talgo trainsets, the internal design is very similar to the DB Class V 200.0 with the same engine and hydraulic drive, and similar bogies, though the exterior, and gauge are totally different.〔 A further five locomotives were then built by Babcock & Wilcox under license. Being designed solely in order to pull Talgo III trains they have only one cab, an automatic Scharfenberg coupler, buffers specially adapted, and the necessary auxiliary power supply equipment. Each locomotive has two engines, each with its own transmission〔Because of the dual engine design the eternal problem of these machines is cracks the head gaskets - due to stresses between the two engines〕 The two twelve cylinder engines each developed and initially travelled at a maximum speed of , a high speed for the time. In 1986 the maximum line speed limit was increased by RENFE to . Upon delivery of the 2000 T the trains are tested using wagons from Transfesa, which were available at the time. AT delivery and decommissioning they carried a red and silver livery,〔In the 1990s two were painted briefly in RENFE's 'taxi' livery - yellow and dark blue/grey〕 like all locomotives for the Talgo service, they are given names. Initially the locomotives had a 'wrap around' windscreen, in the 1980s they were refurbished with the windscreen replaced as part of a cab upgrade and air condition was fitted on the roof at the same time.〔 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「RENFE Class 352」の詳細全文を読む スポンサード リンク
