Metro Kapsul is a public transportation developed to solve traffic problems and save travel time in Bandung. It is categorized into Light Rail Transit and has a capacity of 70 passengers per capsule. Before it operates, a series of technical analysis is needed in order to ensure the vehicle’s properness and safety, one of which is dynamic analysis of the bogie. The research starts with a literature study, discussion, vehicle specification data gathering from PT Teknik Rekayasa Kereta Kapsul, and formulation of the motional relationship between components on Metro Kapsul. From the formulation of the motional relationship, free body diagrams of components are made and forces on each component are calculated. Calculations are done based on the motion of Metro Kapsul when it is about to enter a turn and is turning. The first calculation is done by solving force equations. The second calculation is based on two cases, lateral force only acting on guide wheel or on wheel, in order to determine the proportion and to be validated. The results from the two previous methods are compared with the calculation using the UIC 615-4 standard to be further analysed. In this study, the input variable is the angular acceleration of the guide wheel frame and knuckle, and the output variable is the force on each of the bogie’s components. The biggest force on all wheels and guide wheels obtained from this study are 8,733.56 N and 39,618.19 N, with the lateral force percentage distribution of 18,06% and 81,94%.
