This study aims to suggest an evaluation method of thermal environment using CFD, not an experiment, which is usual in the field. Model train is the newly introduced Mugunghwa train. Since its compartment occupies a large space and chairs and other accessories make it a complicated structure, 3-D calculation might take too much time and effort to make evaluation itself possible. Therefore, we suggest a 2-D model to replace the original 3-D model for averaged temperature and temperature distribution in the cabin.
