The purpose of this thesis is to study wear resistance of wheel-rail contact materials ofrnManganese steel and Pearlite steel. The wheel-rail contact is a critical interface in the railwayrntechnology and study of failures in most railways may cause due to wear of wheel-rail contactrnsurfaces. Application of this thesis is on railway technology in the specific area of Addis AbabarnLight Rail Transit. It is a new railway technology in Ethiopia. So researches on this area arernneeded to identify the existing problems and to avoid such problems from the start. rnThe method of this thesis is numerical and analytical analysis of wear resistance of Manganesernand Pearlite steels. Based on this method wear and wear resistance of wheel-rail contactrnmaterials are evaluated. rnUsing the results of wear and wear resistance of Manganese Steel (current material of AddisrnAbaba Light Rail Transit) is compared with Pearlite Steel (new material). Since, wear volume ofrnManganese steel and Pearlite is 0.00169 mrn3rn3rn and 0.00141mrn respectively at maximum load and rnmaximum distance traveled and wear rate value of Manganese steel is 0.00000335 mrn3rn/m and rnPearlite steel is 0.00000205mrn3rn/m. On the other hand wear resistance value of Manganese steel rnand Pearlite steel is 3.98ern5rn5rn3rn and 4.88ern m/mrn respectively. And also wear index value of rnManganese steel is 1846.43 and 1599.97 for Pearlite steel. Results of this wear analysis showsrnthat there is less amount of wear volume, wear rate and wear index in Pearlite steel thanrnManganese steel. On the other hand wear resistance of Pearlite steel has higher than Manganesernsteel. Finally, this thesis verified that Pearlite steel is better in hardness than Manganese steel.
