Kaikyō Line
41°22′28.16″N 140°17′13.2″E / 41.3744889°N 140.287000°E
The Kaikyō Line (海峡線, Kaikyō-sen) is an 87.8 km (54.6 mi) railway line operated by Hokkaido Railway Company (JR Hokkaido). The line connects Naka-Oguni Station in Sotogahama, Aomori, through the Seikan Tunnel connecting Honshu and Hokkaido, to Kikonai Station in Kikonai, Hokkaido.
The line was opened on 13 March 1988 in conjunction with the opening of the Seikan Tunnel. In addition to passenger trains, freight services operated by Japan Freight Railway Company (JR Freight) operated on the line.
The Hokkaido Shinkansen commenced operation on 26 May 2016 replacing all conventional line passenger services, with the Kaikyō Line now only used by freight trains (and from May 2017 the luxury cruise train Train Suite Shikishima).
The line was built to accommodate the future Hokkaido Shinkansen, but when the line opened in 1988 it was built solely with 1,067mm narrow gauge track which was the standard for both JR passenger and freight lines.
In preparation for the Hokkaido Shinkansen, the line was converted to dual gauge - 1,067mm narrow gauge and 1,435 mm standard gauge track.
The line was originally electrified at 20 kV AC (50 Hz) and was changed in May 2016 to the Shinkansen-standard 25 kV AC (50 Hz). To continue freight operations, JR Freight introduced Class EH800 dual-voltage locomotives.
The junction of the Tsugaru Line and the Kaikyō Line is Shin‑Naka‑Oguni Signal Station (新中小国信号場, Shin-Naka-Oguni Shingōjō)[ja], 2.3 km (1.4 mi) north of Naka-Oguni Station. Approximately 1.4 km (0.87 mi) north of Shin‑Naka‑Oguni Signal Station the Kaikyō Line curves to the right, with the outbound track passing underneath both Hokkaido Shinkansen tracks before merging with it and entering the Ohira Tunnel (大平トンネル, Ōhira Tonneru).
