To further improve train transport quality by ICT, we have developed software system for quick recovery from transport disorders by utilizing tablet PCs (,tablets,) for train crews. The three main functions we currently implemented to the tablets were "timetable transfer", "computerization of (or digitized, electronic) rule books and manuals", and "tablet location identification". Here, we took the strategy to use general-purpose ICT device as much as we can, and focused on higher reliability, faster development, and cost reduction. In the field tests, all crew members (conductors and drivers) of a crew depot who participated in the tests carried a tablet during their daily operation, and had a questionnaire after the trial. As a result, they were able to smoothly use these functions without any serious problem. Especially, the rescheduled timetables real-time online transfer to the tablets in transport disorder shortened time to make necessary train crew re-arrangements to faster resume recovery train operation. Incorporating the findings of the development and testing, from the 2013 fiscal year, all crew members in our company have carried the tablets during their operation. Into the future, we will further improve response to abnormal situations so as to quickly resume operations by utilizing the latest technologies such as tablets. And to accomplish that, we will speed up development for improving transport and service quality.
