Common Defects of Steel Rails
Steel Rails are essential to the efficient operation of the railway system. Railway tracks are made up of steel rail components that are designed to support the safe and speedy movement of a train over long distances. Rail defects can lead to a number of problems that can cause delays to rail services. In order to identify and fix these problems, it is essential to firstly understand the common defects that are associated with steel rails.
The most common defect of a steel rail is referred to as a ‘low-magnification’ or ‘low-amplitude’ defect. This defect is usually caused by an uneven wearing of the rail or by the effects of corrosion. Low-magnification or low-amplitude defects can appear in different areas of the rail and often require a detailed inspection of the area to be identified. Such defects can cause problems with the ride quality of the train and if left unchecked, could lead to permanent damage to other components of the railway track.
Another common defect of steel rails is a ‘fatigue defect’. This type of defect is caused by fatigue that is caused regularly as the rail is subjected to the weight of the train and the pressure of movement along its length. Fatigue defects commonly appear towards the outside of the rail and often result in the need for repair. Such repairs could include welding reinforcement onto the affected sections of rail in order to provide additional support.
Finally, one of the most common problems that can occur with steel rails is the ‘buckling defect’. This form of defect appears in the middle of the rail and is caused by the gradual build-up of stresses over time. This form of defect often leads to the need for replacement of the rail, as any form of repair is generally not considered to be sustainable in the long run.
In conclusion, there are a number of common defects that are associated with steel rails. These include low-magnification or low-amplitude defects, fatigue defects, and buckling defects. It is important to be able to identify these defects in order to make necessary repairs or replacements to the rail. Regular monitoring should also take place in order to ensure the safe operation of the railway network.
