<p align="justify">The latest development of the capsule train design, which designed by PT Treka uses a bogie design with bolster. This design needs to be tested for its stability performance on straight track and cornering trajectory. The testing done by modeling and simulation on the software. <br /> <br /> Modeling and simulation is done on multibody-system basis with Universal Mechanism (UM) software. The UM software has two modules: UM Input and UM Simulation. Modeling is done by dividing the capsule train system into three subsystems namely the body subsystem, and two bogie subsystems performed on the Input UM module. The completed model is then validated by measuring the normal force under static conditions and steering force on the driving conditions on the cornering path. <br /> <br /> The valid model is then analyzed for its stability performance which is running stability and curving performance with UM Simulation software. The reference that used in assessing the stability performance of the capsule train is UIC-518. <br /> <br /> Based on the result of simulation and analysis, it can be concluded that the capsule train, with bogie design using bolster, is safe to operate on a cornering track with a minimum radius of 80 m with operating speed of 30 km / h. On a straight track the capsule carriage is securely operated at speed up to 90 km / h and the critical speed of the capsule carriage is 110 km / h.<p align="justify"> <br />
