IMPROVEMENT OF THE LIGHTING SYSTEM DURING THE TRACK MAINTENANCE ON ADDIS ABABA LIGHT RAIL TRANSIT
Main Article Content
Abstract
Track maintenance realized at the right time is critical for achieving efficient and optimized maintenance and renewal work plans, thereby increasing the life of track component; whereas work done later is unquestionably unsafe, and maintenance and renewal costs rise exponentially as the railway track gets older. The rising demand for train service necessitates large investments in track maintenance and repair. The railway system's efficiency is increased through cost savings and better maintenance management. Addis Ababa Light Rail Transit Service (AA-LRTS) conducts the track maintenance during the night due to the fact that the track is no longer in operation within this period. Different precautions are undertaken in order to protect the manpower but the lighting issue is no longer well considered during the track maintenance while this light is more necessary to light the workplace and to carry out some activities such as the verification of the inner rail performance. The review of different articles related to the key words mentioned within the study topic and the observation carried out during the track maintenance with the maintenance team of AA-LRTS are referred to achieve the goal of this study. The present study is going to highlight the robustness and weakness concluded from the methods adopted by AA-LRTS for track maintenance. Various suggestions are mentioned for the optimum safety required to achieve a reliable maintenance operation and manpower life improvement. By respecting the suggestions provided by the author, the maintenance team will develop the efficiency of the maintenance operation and the manpower life will be saved.
