HistoryAfter the positive experiences from the locomotive Class E.632 with DC traction motors with thyristors, FS wanted to order a new generation high performance locomotives with AC traction motors (also called Induction, three-phase or asynchronous motors). At the beginning of 1990s FS studied, in collaboration with the two companies Ansaldo Transporti (mechanical part) and TIBB (electric part, the Italian part of the BBC company) a new locomotive that could haul both heavy goods trains and high speed trains, the later at speeds up to 220 km/h. The result was class E.402.0. Later, Siemens took over the development for the electric part. A total of six prototypes have been built (E.402.000 - 005), which have seen a long phase of test runs before finally entering active service. The prototypes differ from the standard units because of the edgy shape of the driving cabin, similar to the one of E.632/633 locomotives, while the others have a more aerodynamic one. Class E.402 was one of the first Italian locomotive fitted with induction motors. Prototype 402.001…402.005 (tot 5) First Batch 402.006…402.045 (tot 40) In July 2014 FS made a contract with Spanish CAF to modernise 40 series production locomotives numbered E.402.006 - 045. The upgrade work also includes rebuilding the locomotives with a single cab. After modernisation the locomotives will be used on IC services. E.402B{{anchor|E.402B}}E.402B represent an evolution of the class E.402, with different driving cabins and equipment. 80 units have been built (numbered 101-180). This locomotive, unlike its predecessor, is able to run under different voltages, the Italian standard 3 kV DC and the new high speed lines at 25 kV AC. Further, units 139-158 are able to run under French 1.5 kV DC (at half power), and are classified as E.402BF (F stands for Francia, France). They mount a single ATR90 pantograph and two single arm pantographs for use on French network (1.5 kV DC and 25 kV AC), and French safety systems (Vacma, radio, KVB). Curiously they haven't been authorized to go to Ventimiglia and Modane stations, which are on the border with France, and have 1.5 kV DC catenary. E.402BF, also, can be used to remote command another locomotive of the same class, but not to be remote commanded from driving coach; on normal E.402B, this is reversed. Today both classes are often seen hauling Intercity, sometimes freight, services and are the only locomotives able to be remote commanded by Z1 driving cars via TCN, allowing push-pull services. Technical detailsBoth locomotives have four asynchronous three-phase motors, but the traction circuit is different:
The auxiliary equipment (fans, compressors ecc.) are fed at 450 V 60 Hz AC voltage produced by two 210 kVA static converters. See also
