Alstom Traxx is a modular product platform of mainline diesel-electric and electric locomotives. It was produced originally by Bombardier Transportation and later Alstom, and was built in both freight and passenger variants. The first version was a dual-voltage AC locomotive built for German railways from the year 2000. Later types included DC versions, as well as quadruple-voltage machines, able to operate on most European electrification schemes: 1.5/3.0 kV DC and 15/25 kV AC. The family was expanded in 2006 to include diesel-powered versions. Elements common to all variants include steel bodyshells, two bogies with two powered axles each, three-phase asynchronous induction motors, cooling exhausts on the roof edges, and wheel disc brakes.

Allgemeine Elektricitäts-Gesellschaft AG was a German producer of electrical equipment. It was founded in 1883 by Emil Rathenau as the Deutsche Edison-Gesellschaft für angewandte Elektricität in Berlin.
