To overcome bad conditions of surroundings, construction cost is increased and environmental issues are sometimes rising. Because railway alignment have to be designed to improve efficiency of train performance. The efficiency of train performance is affected by train ability, railway condition, system condition etc. Among these factors, deceleration and acceleration are main factors that determine the capability of train performance. Designed railway alignment is currently verified by TPS(running time, average velocity, Input energy), however, there is no obvious criterion for applicability of deceleration and acceleration. Moreover, results due to changes of deceleration and acceleration tend to be derived irregularly in process of programming. Therefore in this study, problem of applied program is considered by investigating the results for modelled alignment. And efficiency for train performance is also examined by increasing the velocity limit of downward slope which is prescribed by Train Operation Manual.
