At the same time of E 636, FS projected a smaller loco to be used with local trains. E 424 had only two two-axle trucks, similar front ends to E 636 and a shutter on the sides that gave access to a baggage room.
This has been the first class of Italian locomotives to be equipped with the automatic device for rheostat exclusion (I don't know the right term for it) being until then used only in electric railcars.
Only three prototypes were built before WW2 but, after the war, building restarted and finally a total of 158 units were in service with many variants in the electric scheme, the traction motors, gearing and the type of bushings. The power rating varied between 1400 and 1700 kw and the speed between 100 and 120 km/h (62 to 74 mph)
For many years they became a familiar sight at the head of a rake of old coaches and from 1986 more than 100 units were transformed for use in push-pull mode with remote control from a piloting coach in the same time changing livery and losing the never used baggage room.
Locos that remained in the original state have been retired from 2001 and the transformed ones from 2007. E 424 has been a good machine for local trains, beloved by drivers, but had to be used only in passenger services because the rheostat was not dimensioned for freight services.
Some units have been preserved by railfans associations.
