The Ōu Main Line (奥羽本線) is a rail line in Japan. Part of the East Japan Railway Company, it runs from Fukushima Station in Fukushima, Fukushima through Akita Station in Akita, Akita to Aomori Station in Aomori, Aomori Prefecture. Since the opening of the Yamagata Shinkansen on July 1, 1992, the Fukushima–Yamagata section (as well as the Yamagata–Shinjō section since 1999) is known as the Yamagata Line. See Yamagata Line for further details on this section.

[edit] Service
The Ōu Main Line is split into the following four sections. Due to the differences in the tracks of these sections, there are no trains that go through more than one (with the exception of an Akita–Shinjō connection).
[edit] Fukushima–Shinjō (148.6 km)
On this section the Ōu Main Line shares the tracks with the Yamagata Shinkansen. The rail gauge is 1435 mm to allow the Yamagata Shinkansen to run on it. The Ōu Main Line is known as the Yamagata Line on this section.
[edit] Shinjō–Ōmagari (98.4 km)
Crossing the Yamagata-Akita border, there is little demand in this section, and all trains run as local trains.
[edit] Ōmagari–Akita (51.7 km)
On this section the Ōu Main Line shares the tracks with the Akita Shinkansen. Because the Ōu Main Line occasionally runs from Akita to Shinjō as a local train, this section contains one standard gauge track and two narrow gauge tracks. Also, the few Komachi trains running on this section have the priority.
[edit] Akita–Aomori (185.8 km)
Together with the Kosei Line, Hokuriku Main Line, Shinetsu Main Line, Hakushin Line, and the Uetsu Main Line, the Ōu Main Line is one of the express lines and freight lines that make up the Nihonkai Jūkan-sen (Sea of Japan Trans-Japan Line).
