Overview of the Ansaldo E424

Discover the E424 electric locomotive, an icon of the Italian railway landscape.

Designed for power and versatility, this machine served the Italian State Railways with dedication for decades.

Built between 1943 and 1951, the E424 stands out for its robustness and reliability. With a top speed of 120 km/h and a power output of 1550 kW, it was capable of tackling demanding tasks on 1435 mm standard gauge track.

Its Bo'Bo' configuration ensures excellent adhesion and maneuverability, essential for both freight and passenger transport. The weight of 72 tons and a tractive effort of 168 kN testify to its ability to haul substantial trains.

The E424 operated on a 3 kV DC electric system, a common standard at the time. Its 15.5 meters length made it a compact yet effective locomotive for many applications. The multiple builders, including Ansaldo and Breda, underscore its historical importance.
