Abstract: Railway transportation is one of the important infrastructure facilities that are needed in the achievement of effective development; and provides an efficient, cost-effective and environmental friendly transport system which can quickly haul large volumes of goods which are not easily transported through motor vehicles for long distances. Railway track structures are the main component of railway transportation. But Ethiopia has no railway track standard. The analysis and design of track structure in Ethiopia is conducted based on other countries standard. The present research work mainly focuses on the comparison of AREMA and Chinese track analysis and design methods, based on service life of the track bed. To achieve the research objectives, efforts were made to compare the two standards, including literature review, collection of data for the test track components and analysis of track structure using the aforementioned standards. Finally, the KENTRACK program was employed to perform damage analysis of the track structure based on mechanistic-empirical principle. In general, the AREMA standard produced a higher sleeper cross-section dimension, thicker ballast section and heavier rail section. Moreover, the damage analysis indicated that the AREMA standard produced a higher service life than the track structure designed according to Chinese standard.
