All trains are local (all-stations) services, with approximately eight to nine trains in each direction per day. Only three round-trips operate over the entire line, and some seasonal trains operate through onto the line from the Ban'etsu West and Jōetsu lines.[1]

Due to the many curves on the line trains take over four hours to traverse its 135.2 km (84.0 mi) length.

History

The Aizu-Wakamatsu – Aizu-Yanaizu section opened between 1926 and 1928. The line was extended to Aizu-Miyashita in 1941.

At the western end, the Koide – Oshirakawa section opened in 1942.

The Aizu-Miyashita – Aizu-Kawaguchi section opened in 1956, with the extension to Tadami opening in 1963.

The two sections were connected with the opening of Tadami – Oshirakawa (as a passenger only section) in 1971.

Freight services ceased between 1980 and 1982.

  • C11 289 between Aizu-Nishikata and Aizu-Hibara, November 1973
  • C11 289 between Aizu-Miyashita and Aizu-Nishikata, November 1973

Service disruptions

Heavy rain storms in July 2011 forced the section of the line between Aizu-Kawaguchi and Ōshirakawa to be closed. The section between Tadami and Ōshirakawa was reopened from 1 October 2012, but the restoration of the remaining section between Aizu-Kawaguchi and Tadami is estimated to be completed by 2021.[2][3] A replacement bus operates where the line is interrupted.
