History and design

The class are developent of the 1978 MaK G 1202 design; both locomotives have the same exterior dimensions but the G 1204 has a 1,120kW MTU 12V 396 of slightly increased power over the MTU 12V 331 engine used in the G 1202.[2][1]

Operators

Ruhrkohle AG operated 6 of the class, Wanne-Herner Eisenbahn und Hafen 2, NIAG 2, Osthannoversche Eisenbahnen 2, Westfälische Landes-Eisenbahn 2, and Sersa of Switzerland 3,[1] with one locomotive operating under a number of different companies.[3]

Two units originally working for Sersa were transferred to the Swiss Federal Railways in 1993 and operate as SBB Am 842.000 and SBB Am 842.001.[4][5]
