There are significant productivity gains to be realized in track maintenance through capital expenditure in both the maintenance task itself and by moving to higher quality, lower maintenance track. The track maintenance scheduling problem, which involves the allocation of maintenance projects to time windows and crews to projects, is formulated here as an integer programming model. The model presented here was applied to a 89 km track corridor on the eastern coast of Australia. Increasing the time window by moving less important trains was shown to reduce potential delays significantly. The model could be used by local track managers and train planners in real-time so that adjustments could be made to a planned schedule of projects in the light of unplanned train services or train cancellations.
