The 1067mm-gauge locomotives will be used to haul coal trains in southern Sumatra and will expand PT KAI’s existing fleet of more than 50 GT38AC locomotives which have been in service since 2011.
The six-axle GT38AC locomotive is powered by an eight-cylinder EMD 710 diesel engine with ac traction. The 1491kW locomotive has a starting tractive effort of 450kN and a dynamic braking effort of 226kN.
The locomotive weighs 108 tonnes and is 18.94m long over the couplers and 3766mm high. It has a maximum speed of 80km/h.
Progress Rail expects to deliver the locomotives to Indonesia in late 2021.
