The movement of trains may cause some of the gravel to dislodge, disrupting the form of the track. A machine is used to rearrange these pebbles so that the structural integrity of the tracks is not compromised.
Every four years, the body of the train is also lifted from the wheels so that the wheels can be taken apart and washed. These parts are then taken further apart to be inspected and polished by hand. “Each piece is hand-polished, the ultimate proof that hard technology relies on a human touch,” the show’s host said. This video is third in a series of documentaries titled ‘Super Japan’, which explores Japan’s transformation from an ancient culture to a global powerhouse. Watch the video above.
