The RENFE Class 311 is a class of four axle Bo'Bo' diesel electric shunting and light freight locomotives. ==Background and design== The prototype locomotive 311.001 was designed by M.T.M. (Barcelona), Ateinsa (Madrid) and Babcock and Wilcox (Bilbao); the project was led by the Instituto Nacional de Industria.〔The locomotives are sometimes known as Mabi from the initials of the companies involved in the design of the locomotive.〕 The prototype locomotive led to an order of 60 units, which were assigned to the subclass 311.1, and numbered 311.101 to 311.160. The transmission system uses 4 axle hung pinion drive three-phase asynchronous motors powered by a three phase alternator driven by a MTU engine partly license built by Bazán. Siemens supplied Sibas-16 microprocessor engine control systems.〔(【引用サイトリンク】title=Las modernas locomotoras de maniobras de Renfe de la Serie 311 )〕 The prototype locomotive was initially painted orange with a white stripe, the series production were all given a red/silver livery; standard for RENFE shunting locomotives. Some units have subsequently received a more recent white/grey renfe livery. As of 2010 most of the units are operated by RENFE Mercancías, about one third have been assigned to the infrastructure company Adif.〔(【引用サイトリンク】title=ADIF - 311 )〕 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 311」の詳細全文を読む スポンサード リンク
