JR EAST Technical Review
39: R&D for Operation and Maintenance

We published this JR East Technical Review to provide information of our R&D. We expect more people be informed about the characteristics of our R&D, and thereby to encourage people to suggest how the progress can be made if new technologies are applied at our R&D efforts.
