This line has steep gradients and long tunnel sections, as the line was originally built to shorten the Sanyō Main Line along the old San'yōdō.
The 300 subseries entered service on the Fukuchiyama Line, while shortened consists began running on the Nara Line, Kosei Line, Kusatsu Line, and on the Sanyō Main Line in the Okayama area on the Sunliner service.
