Inadequate public transportations make people use private vehicles, while it may cause traffic jams, especially in the big cities. Metro kapsul trains are expected to be one of the solutions to the transportation problems of the big cities. In order to guarantee the passengers’ safety aspect, the metro capsule train must be in line with the safety points of regulations, which is about the strength of the structure while withstanding the operating load and worst-case load condition. This bachelor task has the purpose to comparing simulation finite element method with line model and solid model, and define the safety level of upper frame structure based on the standard of ANSI/ASCE/T&DI 21.2-08. The analysis of the structure is started with the study of literature, collecting the information related with the models and specifications of the metro capsule train, operation patterns, determination design standards, the formulation of various loading cases, finite element modeling, and the level of structure safety according to the standards of safety regulations. The results of operating load and the worst-case load for both line model and solid model have a value that is adjacent to the average error of 15.7% and 13.1%. From the results of finite element analysis, it is obtained that the highest stress range occurs on the vertical operating load, with a value of 54.36 MPa on the line model and 48,11 MPa on the solid model. In the worst case load categories, the highest stress occurs on the condition of the turn-flat sudden brake which has a stress value Von-Mises 296.76 MPa on the line model and 259.82 MPa on the solid model. The critical location is
