The Krauss-Maffei ML 500 C industrial and works locomotive was built between 1954 and 1966 by Krauss-Maffei. When the Wilhelmsburg Industrial Railway (Wilhelmsburger Industriebahn) was taken in 1962 two units ended up in the Deutsche Bundesbahn fleet and were incorporated in it as DB Class V 50. Because there were sufficient Class V 60 locomotives available at that time, the two 'loners' were sold in 1964.
