Electromagnetic rail brake (also called magnetic track brake) is a kind of contact friction braking, basing on the track /rail adhesion. The main purpose of this study is to analyze the wear of the dry contact between rail shoes/rail of the AA-LRT train during emergency braking. CATIA software was used for the modeling purpose. The analysis in this thesis used both numerical and analytical method. The numerical analysis is used to determine the amount of wear. The thermal analysis of the track brake was carried out using ANSIS workbench. In this work, a transient thermal and structural analysis was carried out to investigate the temperature variation on the pad area, total heat flux using ANSYS software. The thermal-structural analysis is then used to determine the stresses established in the rail shoes area.
