Through broad research and design strategy setting, we found a big idea of ‘An endless flow’ which means to provide design, service and speed that does not change over time. The idea came from the train would be used for a long time once it was operated. The formative language of ‘An endless flow’ have been expressed as an exquisite combination of streamlined flowing edges and crossing edges.






The tight surface formed through edge across completed the look with a future-oriented and strong identity that was not present in the existing train market. The edges and surfaces are designed not only for the aesthetic design but also for the functional role to prevent the shaking of the wheels in consideration of the crosswind contact and aerodynamics.
