QR National 5000 class
The 5000 class are a class of diesel locomotive built by United Group Rail, Broadmeadow for QR National between 2005 and 2007. History. In 2004, QR National ordered twelve 5000 class locomotives from United Group Rail. They were a heavy haulage version of the NR class and were purchased to haul coal trains from Mount Arthur mine, Muswellbrook in the Hunter Valley. Each locomotive utilises the 3000kw (4000hp) General Electric 7FDL16 power plant also seen in American locomotives such as the Dash 7. GE 5GEB13 AC traction motors transfer this power to the rail through bogies  in the Co-Co formation. The 5000 class weighs approximately 180 tonnes. In 2012 QR National was rebranded as Aurizon and a number of 5000 class locomotives were repainted into the new yellow Aurizon livery. 5000 class locomotives are often seen operating with one unit at the front of the train and one at the rear (in the UK known as 'top and tailing') either with other 5000 class units or 5020 class units. A third locomotive is required for heavier trains.
