historical KraussMaffei company building with inscription

KraussMaffei was formed in 1931 from a merger of the two Munich firms of Maffei (founded 1838) and Krauss & Co. (founded 1860). Both belonged to the leading German makers of locomotives of various types. Maffei also built other steam-operated vehicles and, later, manufactured vehicles with combustion engines, including locomotives, trolleybuses and buses until the 1950s.

In the 1960s, Krauss-Maffei built several examples of the ML 4000 C′C′ diesel-hydraulic locomotive for demonstration and testing on American railroads. Southern Pacific and Denver & Rio Grande Western Railroad participated in the tests, but both found the locomotives unsuitable for service in the rugged Rocky Mountains through which the two railroads ran. In 1963 the company started production of the Leopard tank, with production of Leopard 2 starting in 1973. In the seventies they were involved in the development of the Transrapid magnetic levitation train. In 1999 the company merged with Mannesmann Demag.

KraussMaffei's defense and locomotive component was later spun off and merged with Wegmann & Co to became Krauss-Maffei Wegmann in 1999. In 2016, KraussMaffei was purchased by ChemChina.[1][2]

In November 2018 KraussMaffei was the victim of a ransomware attack, leading to severe drawdown in the production.
