Ban'etsu West Line

The Banetsu West Line (磐越西線) is a railway line in Japan operated by East Japan Railway Company (JR East). It connects Kōriyama Station in Kōriyama, Fukushima Prefecture, and Niitsu Station in Akiha Ward, Niigata, Niigata Prefecture. The name "Banetsu" is taken from the first characters of the names of the ancient provinces of Iwaki (磐城) and Echigo (越後), which the Banetsu East and Banetsu West lines connect. "Sai" (西) means "west" in Japanese.

The line's nickname is the Mori to Mizu to Roman no Tetsudō (森と水とロマンの鉄道).

History
The private Ganetsu Railway opened the initial section from Kōriyama to Nakayamajuku on July 26, 1898, and extended the line to Aizu-Wakamatsu the following year.

Japanese National Railways (JNR) started to modernize the line in the 1960s, introducing the line's first limited express service (as a part of the Yamagata-bound Yamabata) in 1965 between Ueno Station in Tokyo and Aizu-Wakamatsu via the Tōhoku Main Line. In 1968 the train was renamed Aizu Yamabata, but from 1993 onward it was renamed Viva Aizu and ran only between Koriyama and Aizu-Wakamatsu. The train was finally discontinued as a limited express service in 2003.

In 1967, JNR electrified the section between Kōriyama and Kitakata at 20 kV AC.

In 2011 the line was closed for 15 days in March following the Tohoku earthquake, two days in April as a result of aftershocks, and for 10 weeks following torrential rain at the end of July.

A new station, called Kōriyamatomita, opened on 1 April 2017 between and Kōriyama and Kikuta stations.

The railway bridge connecting Kitakata and Yamato collapsed due to heavy rain on 4 August 2022. All services are suspended between Kitakata and Nozawa.
