FS Class E.405
The Ferrovie dello Stato, FS Class E.405 is a class of electric locomotive built in 42 units by ADTranz (now Bombardier Transportation Italy) originally for the Polish State Railways (PKP), but later acquired by Trenitalia Italian state railways. History The locomotive batch was originally commissioned by PKP in 1996 and the units were assembled in Poland at Wrocław Bombardier Transportation Polska's plant, with the designation of EU 11. After a short operational stint of 8 locomotives on the Warsaw-Berlin line, they were later switched to Italy's Ferrovie dello Stato (FS), which later rechristened them as E.405 in May 2003. They are a development of the similar FS Class E.412, E.412, which are however designed for international goods transport and have polycurrent motor equipment (E.405 can operate only on 3000 V direct current lines). They have a maximum speed of with trains up to , although in Italy they can be used only up to ( for goods trains). Thanks to their rela ...

Electric Locomotive
An electric locomotive is a locomotive powered by electricity from overhead lines, a third rail or on-board energy storage such as a battery or a supercapacitor. Locomotives with on-board fuelled prime movers, such as diesel engines or gas turbines, are classed as diesel-electric or gas turbine-electric and not as electric locomotives, because the electric generator/motor combination serves only as a power transmission system. Electric locomotives benefit from the high efficiency of electric motors, often above 90% (not including the inefficiency of generating the electricity). Additional efficiency can be gained from regenerative braking, which allows kinetic energy to be recovered during braking to put power back on the line. Newer electric locomotives use AC motor-inverter drive systems that provide for regenerative braking. Electric locomotives are quiet compared to diesel locomotives since there is no engine and exhaust noise and less mechanical noise. The lack o ...
