History
The Ōigawa Main Line began operations on June 10, 1927 as a private line for the Ōigawa Electric Company, to carry workers and materials upstream to facilitate dam construction. The single-track line was extended from Kanaya in stages, reaching it current terminal station of Senzu on December 1, 1931.

The entire line was electrified on November 18, 1949, with EMUs for the passenger services commencing then and freight operation by electric locomotives beginning in August 1951. Express train operations commenced in 1971.

The line runs through an isolated mountain area with no cities or towns, and has a very small population density. Most of the passengers are tourists visiting one of the hot spring resorts along the line, or alpinists and hikers heading for the peaks of the Southern Alps National Park. To boost ridership and popularity of the line, steam locomotives were restored from July 9, 1976. A variety of historical locomotives and carriages are used, both for the steam and for the electric services, making the line a favourite with train enthusiasts and photographers.

Freight services ceased in 1983.
