Railway track infrastructure / Nur Izyan Abdul Mukmin

The railway infrastructure that describes the railway track and all the civil engineering structures and systems that ensure the railway traffic. Hence, the railway track comprises successively from top to bottom the rails, the sleepers, the ballast, the sub-ballast, the formation level, and the subgrade. The study aims are to determine the process of the construction of railway track infrastructure in Malaysia. There are the methods of railway track infrastructure, for example stripping of top soil is be done by removing the top layer of soil containing organic material, which be stockpiled for the use of works, i.e. reuse for the soiling of slopes, berms, and/or disposed into the approved dumping sites when there’s in excess of required quantity or as directed by the consultant. There are many types of problems and the solution taken to solve the problem during the construction of railway track infrastructure. The one of the solution is about the method of replacing the poor soil is first removed and then the gap is filled up by superior material such as sand, stone, gravel or any other hard material. In order to do this, first excavate a foundation trench of about 1.5 m deep, and then fill the hard material is stages of 30 cm. Then compact the hard material at every stage. This method is useful for foundations in black cotton soils.
