Electric locomotive E.444 005 of FS
Prototype with experimental fans
The E.444 005, also known as the "electronic turtle," was a
prototype for FS and left the works in Vado Ligure in September
1975 as the last "Tartaruga." As a "Full-Chopper," it was equipped
with a fully electronic drive, which was a novelty for FS and
offered advantages in power control, adhesion utilization, and
tractive effort.
With a continuous power output of 5,050 kW and higher tractive
effort than the series locomotives, it was the most powerful E.444
and was easily recognizable by numerous ventilation grilles and
roof structures. After successful test runs, it was taken into
service in 1976 and stationed in Milan Centrale, primarily used in
traffic between Chiasso and Domodossola. Decommissioned in 1981, it
was rebuilt in 1989 in accordance with the locomotives of the 2nd
series.
