Abstract
The objective of this study is to understand the current situation of train delay in urban railway services with train traffic records. The study shows the tendency of worsening punctuality based on characteristics of each line, loop line, direct-through line etc. While conducting present data analysis, the study formu-lates a train operation simulation model which reproduces the situation of train operation taking into ac-count the interaction between the trains during the rush hour. Using the simulation model, the influence is shown quantitatively in Yamanote line, if the early departure is carried out. Moreover, the study suggests the present service level will be preserved by the early departure, if the platform screen doors are provid-ed in all the stations of Yamanote line.
