초록

Recently, freight train with special structure has been considered due to freight volume and distribution structure change. Various freight trains are being operated to transport freight. However, the transportation demand is different, depending on its freight type and route type. The peak time for demand of each freight is also different because the demand of transported freight type or its route is not fixed and freight volume fluctuates critically with the change in season and period. Especially, the usefulness of freight car is reduced remarkably in idle period because the transportation of coal fluctuates with the demand of the coal. And container transportation using railroad is continuously increasing but efficiency is low because container car(or flat car) can not be used to transport other items. Therefore, the container and freight car has been developed for transporting the bulk freight and container freight in the same vehicle to solve the inefficiency and diseconomy due to the lack of compatibility among freight cars. And, the structural analysis has been performed to check the structural stability.
