Urban transportation systems are a crucial component in addressing the growing mobility needs of urban populations. With the increase in population and economic development, public transportation such as Light Rail Transit (LRT) has emerged as an attractive alternative to alleviate traffic congestion and environmental issues in densely populated urban areas. One metropolitan area facing significant mobility challenges is Jabodetabek, comprising Jakarta, Bogor, Depok, Tangerang, and Bekasi. The development of the LRT system in the Jabodetabek region is a strategic step to tackle traffic congestion and air pollution problems. However, operating trains in densely populated cities faces challenges, particularly wheel wear. Examples include the X10 commuter train in Stockholm, Sweden, the DMU Aln 501 Minuetto in Italy, the TRAXX locomotive in Germany, and the LRT in Palembang. This thesis presents research related to the wheels of the Jabodebek LRT. The initial phase involves developing a dynamic model of the train. Once the model is validated, the research continues to investigate the wheel wear of the Jabodebek LRT. Lubrication of the inner rail has a significant impact on wheel flange wear. Lubrication applied to curves with a radius below 92 meters results in a substantially different wear depth compared to dry rail conditions. Additionally, changes in train operating speed were made to determine wheel wear depth. The simulation results indicate that increasing operating speed increases flange wear depth but decreases tread wear depth. Furthermore, the simulation results with varying track gauge widening show that flange wear depth is not affected by the variation in track gauge widening. The simulation results with different wheel profiles show that the current LRT Jabodebek profile produces the lowest flange wear depth compared to the S1002, UIC 510-2, and AAR 1B-narrow flange profiles.
