This study focused on the educational and training materials (DVD) developed by Yamauchi et al.(2012) intended to improve passenger announcements about disruptions. The long term effect of these training materials was verified through the cooperation of a railway company different from the previous one. As a result, the effects of viewing the materials, which did not differ by job category or age, were maintained for more than one year.
