The traction engines are QSK19-R units rated at 750 hp while the generator sets have a 131 kWe capacity and are powered by the ISBe engine. Both the traction and genset engines feature full-authority electronic controls.
The new rail cars will replace 1960s-vintage units which originally had Detroit engines and were then repowered in 1981 with the 14-litre Cummins NTA855-R.
The new cars will enter service early in 2005 and will operate as two-car units, each car having a traction engine and generator set.
The will complement the 10 existing Endeavour units that were commissioned in 1992 with 540 hp Cummins KTA19-R engines and Cummins generator sets rated at 118kWe.
Built by United Goninan at its Broadmeadows facility in Newcastle, the new rail cars are the first designed and built in Newcastle for the Newcastle region.
The Hunter Valley contract follows recent major orders for 76 traction engines and generator sets for Victoria’s high-speed VLocity trains, and 18 engines for new rail cars for the Perth to Kalgoorlie Prospector service.
The VLocity trains have QSK19 engines rated at 750 hp and 80 kWe gensets, while the Prospector trains are powered by 525 hp N14-ER engines.
