The tour was organized by JR Shikoku and the Honshu-Shikoku Expressway to commemorate the 35th anniversary of the opening of the Seto-Ohashi Bridge. 27 people from inside and outside the prefecture participated in the tour on the morning of the 19th.
The participants used the elevator to go to the passage next to the railroad tracks, which was located at a high point about 65 meters above the sea level. When the "2000 series" with a distinctive blue line on a silver body passed up close, the participants released the shutter.
