The Aoimori Railway Line (青い森鉄道線, Aoimori Tetsudō-sen^?) is a rail line in Japan. It runs from Metoki Station in the town of Sannohe to Aomori Station in Aomori Prefecture.^[1]

Organization

The Aoimori Railway Line is operated by the Aoimori Railway Company, a "third sector" publicly-and-privately owned company. The railway facilities and tracks are owned by the local prefectural government as a "Category 3 Railway Business" under the Railway Business Act of Japan. The Aoimori Railway Company leases these facilities from the government and is responsible for operation of passenger trains on the tracks. This scheme is intended to mitigate the company's burden as an owner of fixed assets and is known as "track/service separation" (上下分離方式, jōge bunri hōshiki^?).

JR East limited express services continue to use the line, providing through service via the Tōhoku Main Line from Sendai and Morioka to Aomori. Japan Freight Railway Company (JR Freight), the nationwide freight train operator, also uses the line for freight services.

For maintenance work, the line relies on the services of the Hachinohe Rinkai Railway Line.

History

The Aoimori Railway Line was completed as the Metoki – Shiriuchi portion of the Nippon Railway on September 1, 1891. When the Nippon Railway was nationalized on November 1, 1906 it became part of the Japan National Railway (JNR) system and was designed part of the Tōhoku Main Line on October 12, 1909. Initially single track, the line was double tracked in 1968 and a Centralized traffic control system was installed in Aomori Station in 1976. With the privatization and dissolution of the JNR on April 1, 1987, the line came under the control of the East Japan Railway Company (JR East). On December 1, 2002, with the opening of the Tōhoku Shinkansen, the portion of the Tōhoku Main Line located in Iwate Prefecture became the Iwate Ginga Line and the portion in Aomori Prefecture from the Iwate border to Hachinohe Station became the Aoimori Railway Line.

With the opening of the Tōhoku Shinkansen extension to Shin-Aomori on 4 December 2010, the Tōhoku Main Line tracks between Hachinohe and Aomori were transferred to Aoimori Railway ownership.^[2]
