The initial order for 90 locomotives was given to Siemens in 1997 to replace an aging diesel fleet; the railway opted for a locomotive suitable for both shunting and mainline use, rather than separate classes.[4] Siemens sold its locomotive manufacturer division (Siemens Schienenfahrzeugtechnik) to Vossloh in 1998.[5]
The locomotives were variants of the standard MaK G 1200 series design,[2] and are considered a development of the MaK G 1205 type.[1] The locomotive is an off-centre cab design with a two-speed Voith hydraulic transmission driving all axles via cardan shafts.[2] Auxiliary electrical supply is provided by an engine mounted alternator.[4] Unlike many other MaK locomotives which use a MTU or CAT 12-cylinder V engine the locomotive has an ABC 6-cylinder inline engine.[3]
The first locomotive was delivered in October 1999, and worked satisfactorily; a second order for 80 locomotives was given in June 2001.[4][6]
Operationsedit
The first locomotive entered service in February 2004.[7] All 170 units were operational by June 2005.[8]
Due to its relatively low power the locomotives work in multiple on heavy freight trains.
