Track maintenance in the Hunter Valley

The current objectives for track maintenance in the Hunter Valley is to maintain existing tracks to the Technical-Standard with the minimum of disruption to Unit Coal Train working or to other traffic, and to improve specific locations in preparation for regular XPT services. It is proving quite difficult to achieve the stated objective in the Hunter Valley for three main reasons: I. Rapidly increasing tonneage and traffic density is severely limiting the availability of track possession for mechanical maintenance. The crossover facilities currently available are no longer suitable. 2. The increase in train-size and in axle-loads, introduced as part of the "Unit-Coal Train" concept, are straining the thresholds of the structural capacity of the existing track to their limits. The resulting variation in track geometry then becomes too much for XPT operations. 3. Present staffing and funding levels, while they may be suitable for a "stronger" track structure, do not adequately reflect the importance of the traffic, its rate of expansion, nor the inherent maintenance problems so caused, and which require correction before any track strengthening is carried out.
