Lines
In 1988 JR Shikoku, unlike other JR companies, discontinued the classification of its rail lines as either main, secondary, or branch lines. Prior to the change, the Dosan, Kōtoku, Tokushima, and Yosan Lines had all been main lines.Each line is color-coded and labeled with a letter, in conjunction with which a number is assigned to each station on the line. For example, Naruto Station on the Naruto Line is numbered N10. Although this method is now widely used by rail companies, especially metro systems in Japan, JR Shikoku was the first JR company to adopt it.
