The original conventional railway was designed to be stand against 150㎞/h and it is still being operated at the present. However, if the speed of train is improved up to 200㎞/h in the near future in order to get competitiveness, we examined how the speed effect on the rail and we analyzed the effect of vibration, the stress and the displacement of the rail material by the change of the speed and the change of the property of matter through the hydrostatical and the dynamic analysis about the absence of the rail. As the result of the analysis by the above method, we got the prove that the best synthetic hardness of the rail is 75±10KN/㎜. Therefore, it is proved that rail pad has to be improved.

KORAIL is planning to induce EMU(Electric Multi Unit) at the speed of 180㎞/h as an alternative of Saemaeul train(PP;Push-Pull) which is disappearing in 2012 according to the crapped trains out of date and the development of the area around Yong San train station. Accordingly, Korean Tilting Train eXpress(TTX) localized in 2013 has achieved the operation test of 100,000 ㎞ non-accident safely so far, and is continuously scheduled to go through an efficiency test and improvement of train in the future. This study scrutinized the proper manufacture settings of train by making preparation for TTX' import and operation, the whole economy efficiency by analyzing the operational cost such as operating revenue, labor cost, maintenance cost, and power equipment cost in accordance with the introduction of TTX. Therefore, we'd like to maximize the effectiveness of importation and operation of TTX by performing the study on decreasing the operation cost when TTX is working on.
