E.402A/B is a class of electric locomotives mainly used on medium speed passenger trains (max 200 km/h services like InterCity or Frecciabianca) by the Italian railway company FS Trenitalia. == History == After the positive experiences from the locomotive Class E.632 with DC traction motors with thyristors, FS wanted to order a new generation high performance locomotives with AC traction motors (also called Induction, three-phase or asynchronous motors). At the beginning of 1990s FS studied, in collaboration with the two companies Ansaldo Transporti (mechanical part) and TIBB (electric part, the Italian part of the BBC company) a new locomotive that could haul both heavy goods trains and high speed trains, the later at speeds up to 220 km/h. The result was class E.402.0. Later, Siemens took over the development for the electric part. A total of six prototypes have been built (E.402.000 - 005), which have seen a long phase of test runs before finally entering active service. The prototypes differ from the standard units because of the edgy shape of the driving cabin, similar to the one of E.632/633 locomotives, while the others have a more aerodynamic one. Class E.402 was one of the first Italian locomotive fitted with induction motors. Prototype 402.001…402.005 (tot 5) First Batch 402.006…402.045 (tot 40) In July 2014 FS made a contract with Spanish CAF to modernise 40 series production locomotives numbered E.402.006 - 045. The upgrade work also includes rebuilding the locomotives with a single cab. After modernisation the locomotives will be used on IC services. 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「FS Class E.402」の詳細全文を読む スポンサード リンク
