1. For a non electrified single track Narrow Gauge railway without a full signalling system, the cost is estimated at $1.5M per kilometre. This is for a railway comprising 50 kilogram rail with concrete sleepers with resilient fastenings and crushed rock ballast. This does not allow for bridges and other major crossings but does allow for culverts and other drainage.
2. The life of the railway should be 50 years but this obviously depends on use or amount of traffic and tonnages hauled.
3. Based on a number of rural projects the cost will range from $1.4M to $1.95M per kilometre. The variability arises from factors such as prevailing ground conditions; drainage; proximity of suitable pavement materials, scale of the project; traffic volumes and freight tonnages expected to be carried etc.
4. The design life of a rural road is 40 years. The actual life will depend on the amount, composition of traffic and weather/location factors.
