A Basic Study on a Double Deck Train Model

2층열차 차량모델에 대한 기초연구

In recent years, due to the continuous concentration of population and sharp increment of commuters around Seoul metropolitan area, traffic jam has become one of severe problems along with housing in this area. In oder to solve the problem like the one mentioned above, several countries such as Japan, France and so on gradually operate double deck trains as efficient, reliable and comfortable mass transportation systems. However, the double deck train has weak points such as big cross sectional area and high mass center that cause unsafe vehicle running performances and interface problems between the vehicles and infrastructures. Therefore, prior to operate double deck trains on the existing lines, careful investigations should be performed. For these reasons, we have investigated foreign double deck trains and studied the technologies for a double deck train as an alternative way to carry heavy transportation efficiently and comfortably.
