This research is based on the Jakarta-Bandung KCIC project. The objective of this project is to expand the rail network in Indonesia and improve the quality of PT KAI's services. In this project, it is necessary to transport the R60 rail with a length of 50 meters by a train. A rail support is needed to hold the rail so the rail is not thrown from the carriage when passing through turnout. The objective of this study is to design a safe rail support to withstand the load and analyze the design strength of the rail support when it passes the turnout. In this study, the kinematics and dynamics of the train were modeled using Universal Mechanism. Objective of simulations is to determine the force generated by the rail being transported against the rail support. The support modeling was carried out on SolidWorks 2019 and continued with static and fatigue loads simulation using the finite element method. Simulations were carried out to analyze the stress, deformation, strain, safety factor and life cycle of designs. The results of this simulation are compared with the required criteria and an assessment is carried out to determine the design quality. Kinematics and dynamics simulation has been carried out and resulted a smaller load on the rail configuration without rail partition. There are 6 alternative designs that are modeled in this study. After loading test, it is known that alternative design 2 has the best safety factor over design weight and the best life cycle. After quality evaluation, the final design of this research is the second alternative design with a safety factor value of 2.965 and a life cycle of 1,000,000 cycles.
