The FS Class D.341 is a class of diesel-electric locomotive used in Italy, introduced in the 1950s and still in service. Most of the remaining units are in service with La Ferroviaria Italiana (LFI).

History

The D.341 were part of a post-World War II effort from the Italian state railways FS to replace their steam locomotives on non-electrified lines. They were designed in collaboration with Fiat and Breda and were produced in two series with different engines, depending from the manufacturer. The second series had a slightly different appearance. Two prototypes were also built by Ansaldo and Reggiane.

Description

D.341 has two small cabs, one at each end, separated by a large compartment including the engine, the cooling devices and the transmission. The two engines were both V-12 engines, 12 piston, coupled to a DC 450/700 V generator provided by Magneti Marelli for the FIAT locomotives, and by Breda or Ocren in the others. Power is fed to four electric motors having a maximum power of 177 kW (237 hp) each in the first series, and 192 kW (257 hp) in the second one.
