1 Background
The Sishen-Saldanha iron ore export railway line suffers from unpredictable rail
breaks causing a great loss annually to Spoornet. Rail-breaks are however a
common phenomena in all railways over the world. This can cause very costly
derailments if not detected before the passage of a train. Small amounts of
impurities trapped in the metal structure of the rail are potential points of rail
defect development. The development of these defects is associated with metal
fatigue, which is a function of the loading applied to the rail. Many of the minute
irregularities of metal structures in the rail are a given factor of rail
manufacturing and will most probably never cause an actual rail break. These
irregularities are practically undetectab
