Service
Local train operation is divided into the electrified section between Himeji and Teramae, and the non-electrified section between Teramae and Wadayama. All local trains makes every stop on the line, and no local train runs the entire length of the line.
Local trains stop at all stations. Local trains operate from Himeji to Teramae and from Teramae to Wadayama. Some rapid trains operate from Teramae to Wadayma, stopping at all stations except Hase.
The 29.6km section from Himeji north to Teramae was constructed by the private Bantan Railway (播但鉄道, Bantan Tetsudō) company and opened in 1894, with the 6.3km section to Hase opening in January the following year, and the 7.7km section to Ikuno three months later. The 8.3km section to Nii opened in 1901. The Bantan Railway was purchased by the Sanyō Railway (山陽鉄道, Sanyō Tetsudō) in 1903, which extended the line 13.8km to Wadayama, opening in April 1906, 8 months before the company was nationalised. Individual section opening dates are given below.
The line was named the Bantan Line in anticipation of the Sanyo Railway company being purchased by the Japanese government under the Railway Nationalisation Act of 1906.
The Bantan Railway Co. also built a ~15.7km line from Himeji east to Shikama-Kou (near Kakogawa), opened in 1895 and closed in 1986.
CTC signalling was commissioned between Himeji and Wadayama in 1978, and freight services ceased between 1984 and 1986. The Himeji - Teramae section was electrified in 1998.
