The E.464 is a class of Italian railways electric locomotives. They were introduced in the course of the 1990s for hauling light trains, especially for commuter service. They were acquired by FS Trenitalia to replace the old E.424 and E.646, dating from the 1940s and 1950s. The class was originally designed by ABB Trazione, later ADTranz (now part of the Bombardier group), and produced in the Italian plant of Vado Ligure. Cost per unit is 2.6 million Euro. With 688 locomotives currently in service (as of January 2014) the E.464 is the largest class in use in Italy.〔(【引用サイトリンク】work=International Railway Journal )〕 ==History== The E.464 derives from a project launched by the Italian Ferrovie dello Stato in the 1980s for a "modular" class of locomotives which would be easily adapted to commuter, inter-regional and cargo services. Initially, types with 4-axle (Bo-Bo, E.453/E.454) and 6-axle (Bo-Bo-Bo, E.665/E.666) were devised, the latter for cargo services. However, the E.666 class was cancelled due to availability of the new E.652 ''Tigre'' class, capable of hauling massive cargo trains. Moreover, the new inverter technology was developed in those years, and the E.454 became suddenly obsolete. In 1994 FS requested ABB to design a new class which, to save money, was to be based on already built prototypes and using parts from the new E.412 from the same producer. The first batch of 50 E.464 was issued to the Lazio regional government in 1999-2000, and proved immediately successful. Further orders for 90, 100 and 48 units followed in 2001-2005, plus another 100 in 2006-2007, another 100 in 2009, and finally another 50 in 2011: a total of 688 locomotives, and an investment of over one billion Euro.〔 6 units are also used by Ferrovie Emilia Romagna. 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.464」の詳細全文を読む スポンサード リンク
