Abstract

Abstract This project aims to develop an integrated engineering strategy for the rehabilitation and maintenance of the railway line in the (Atbara – Barbar) sector in the Republic of Sudan, with the purpose of enhancing its operational efficiency and ensuring the highest standards of railway transport safety. The research adopted an approach based on the integration of four fundamental methods; it began with the desk method to review theoretical studies and the construction history of the facility. Descriptive data about the sector and its components were obtained from the Sudan Railways Corporation in Atbara, along with a comprehensive understanding of the mechanisms and manufacturing processes from the tile factory, all under the supervision of managers and supervisors. Then, the field method was used to diagnose current challenges represented by the deterioration of rails and old fishplates, and the reduction of the design speed to 60 km/h, as observed by station inspectors and workers.Starting with the analytical approach based on the results of laboratory tests on the track soil (such as California Bearing Ratio CBR and dry density) to ensure the stability of the embankments and resistance to environmental effects like sand encroachment and floods, leading to the applied solutions approach that provided the necessary engineering treatments. The project concluded with a set of essential recommendations, most notably the need for the full replacement of light rails (50 and 75 pounds) with heavier ones of the (UIC 60) type, adopting the continuous welding (CWR) technology to reduce vibrations, replacing wooden sleepers with prestressed concrete ones, while emphasizing the updating of turnouts with flexible systems and physically marking the railway corridor to deter encroachments and secure the track in the future
