The E.412 class (factory name 112E) is a batch of multi-role electric locomotives built for the mountain lines, particularly for the northern Italian lines of the Brenner pass. They are known as Brenner or Brennerlok locomotives. 28 units from both the groups have been acquired by Trenitalia, as part of a process of unifying the rail networks between Italy, Switzerland, Austria and Germany. The locomotives are qualified for running on French rails, too, making the E.412s a potentially fit for service on most European lines except the high-speed rail lines.
They were initially produced by Adtranz (a consortium made up of ABB Trazione and AEG), but now are built by the Canadian company Bombardier.
In the early 1990s, Ferrovie dello Stato started an operational plan to organize an integrated rail system with the countries on Italy's northern border, following the European political-economic unification process. Austria and Germany used different railway electrification systems, necessitating the use of a locomotive able to use a variety of electric systems: alternate and direct current, varying from 1,500 to 15,000 Volts.
The E.412 class was to be used on the longest, steepest and hardest mountain-crossing line, connecting Verona Porta Nuova and Brennero/Brenner, crowded with cargo and passenger trains and with different electrifications. Before the E.412's were introduced, the route required three locomotive changes. The Italian railroad's goal was for trains to reach Germany without changing locomotives.
