Strategy behind Hunter Valley track strengthening

The Way and Works Branch Strategy in the Hunter Valley is to provide the best possible track structure for the type of traffic being carried both present and future. The Up lines in the Hunter Valley presently carry in excess of 25 million tonnes of traffic per annum, mainly composed of coal and wheat. Axle loads on coal trains of 25t are the heaviest in the system and obviously have a disastrous effect on our normal timber sleepered track structure. It is branch policy that traffic in excess of 12 million tonnes per annum (six million t.p.a. in the case of high traffic density areas), justifies the construction of Class 1XC track. The basic of the justification is sound engineering judgement when you consider the condition of track in the valley before track strengthening.
