Abstract
Railway companies in Japan have been facing various troubles and accidents due to rail car aging，natural disasters or human errors. Nowadays such troubles and accidents tend to be immediately reported to the public in the media after they occur. Although each company takes measures of the highest possible level to ensure passenger safety，it will be still impossible to remove all the troubles and accidents completely. In this research，we build a database to collect railway accident data in Hokkaido. We visualized the accident scene using the database，and found several features many accidents trend. Through this research，the authors try to offer a proposal of a possible improvement activity to railway companies，specifically，a technical-college-version of education program for railway operation so that these troubles and accidents can be avoided as much as possible. This paper reports as an interim step on how the authors have been gathering railway accident records and building their database.
