The RENFE class 252 are a series of Bo'Bo' electric locomotives, built by CAF, Meinfesa, Siemens and Krauss-Maffei for RENFE. 15 units were built for the NAFA (''Nuevo Acceso Ferroviario a Andalucía'') line between Madrid - Sevilla (standard gauge version), and 60 units constructed for general use to Iberian gauge (1668mm). ==Background, design, construction and history== The series of locomotives were ordered to modernise RENFE's fleet and to provide traction on the new standard gauge Madrid to Seville line, on Iberian gauge lines they were to replace RENFE Classes 276, 277 and 278 which were of some age, and incapable of speeds of 200 km/h;〔 the order coincided with the construction of the first standard gauge high speed line in Spain, and was won in 1989 by a consortium of Swiss and German companies led by Siemens including Krauss-Maffei, Thyssen-Henschel, ABB.〔(Renfe S/252: Introduction ) ''www.railcolor.net''〕 The locomotives design was a development of that used in DB Class 120, which eventually led to the Siemen's Eurosprinter family of locomotives; of which the Class 252 can be considered a predecessor.〔 The first 15 locomotives were built to gauge in Germany, a further 60 locomotives were manufactured to gauge by CAF and Meinfesa in Spain.〔 31 locomotives were dual voltage machines operating on 3 kV DC and 25 kV AC, the remaining 44 operated on 3 kV DC only. Subsequent to their introduction some of the locomotives have been re-bogied to both standard and Iberian gauge to meet operational requirements.〔 Locomotives built for the standard gauge high speed lines carried a white/grey 'AVE' livery, whilst the Iberian gauge machines were delivered in 'Taxi'/'Amarillo' (Yellow/Grey) livery, later some carried 'Arco' and 'Altaria' branding. In 2005 all locomotives became part of RENFE Operadora.〔 These locomotives can be seen today throughout the Spanish territory of electrified railway lines. In 1995, 252 054 was seriously damaged in an accident in El Paso Despeñaperros,〔(Renfe S/252 252-054 ) ''www.railcolor.net''〕 being scrapped later in Villaverde Bajo. In 2003 252 062 was involved in an accident in Zuera and scrapped.〔(Renfe S/252 252-062 ) ''www.railcolor.net''〕 In 2010 four locomotives were modified for freight work on standard gauge lines from Barcelona to Le Soler (nr. Perpignan) in France. The vehicles were fitted with ERTMS compatible train safety devices, standard gauge bogies; they will also operated from 1.5kV DC on some sections of the route. 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 252」の詳細全文を読む スポンサード リンク
