Overview: Due to the privatization from Japan National Railway, 6 Japanese Railway Companies were established almost 30 years ago. Shikoku Railway Company, also known as JR Shikoku is the smallest among the 6 and started off with financial difficulties as well as the struggle of competing against the rapidly expanding highways. See how JR Shikoku developed the World's first diesel tilting train which led to the increase of speed and strategies to operate unique tourist trains.
