Concept Design for New Commuting Double-deck High Speed Train with high capacity

초록

Several countries such as France, Japan, and so on have been operating double deck high-speed trains as efficient and comfortable mass transportation systems. The main purpose of double-deck train is to maximize the space of cabin for a given length of train. Europe including France is using the expanded spaces in order to improve the comfortability of passenger by offering the wide bar, service facility and wide seat space. On the other hand, Japan is using them to increase the number of seats. The increase of passengers for a given length of train means the reduction of the carrying weight of vehicle and the energy consumption per 1 passenger. The several major cities in Korea are connected each other by high speed rail network within less than 1 hour and the moving passengers between these cities on rush hour by high speed trains are increasing rapidly. Especially, the introduction of a high speed train with high capacity is needed on the Seoul~Daejeon high-speed rail section where is already crowded at commuting time. In this study, we suggest the concept design for commuting double-deck high speed train in order to maximize the capacity of passenger by considering the formation of train-set, the type of bogie and the optimized space of electrical equipment. And the interior designs including the stair, doors and various seats for dense cabin are introduced in order to reduce the time getting on and off train and keep the good passenger flow in spite of high passenger density.
