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 (was part of the Bombardier group, which was acquired by Alstom in 2021), and produced in the Italian plant of Vado Ligure.

Cost per unit is 2.6 million Euro. With 717 locomotives currently in service (as of December 2015) the E.464 is the largest class in use by Trenitalia,^[2] and also the most numerous Italian locomotive class ever in service.
