FS Class D.341The 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.HistoryThe 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.DescriptionD.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 each V-12 engines 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 each in the first series, and in the second one.
