The FS Class E.320 was a class of Italian
third railelectric locomotive built between 1915 and 1918. Five units were built and they saw service on the
Varese -
Milan -
Porto Ceresio line. They were powered by two
direct currentelectric motors, designed by
Tecnomasio Italiano-Brown-Boveri (TIBB), giving a maximum speed of 95 km/h (59 mph). The final assembly and the mechanical design were by
Officine Meccaniche (OM). At the time of their construction they were the most powerful direct current locomotives in the world. The transmission of the motion to the three axles was by
connecting rods and these were subject to frequent breakages.
The locomotives were soon replaced by
Class E.321.
