The schedule speed is one of the most important elements of railway industry. In korea, Gyeongbu Line’s highest speed is 300km/h. But it’s schedule-speed is no more than about 174km/h from Seoul to Busan. In this study, we analyzed the effect of the proposed improvements in the speed reduction zone using Train Performance Simulation. We found that the improvements can raise the schedule speed from 15 to 20%.
