History

The section from Nakamozu to Izumigaoka opened on 1 April 1971 as the Semboku Rapid Railway Line (泉北高速鉄道線, Senboku Kōsoku Tetsudō-sen), with 1,067 mm (3 ft 6 in) double track and electrification at 600 V DC.^[7] The overhead line voltage was increased to 1,500 V DC from 7 October 1973, and the line was extended to Toga-Mikita on 7 December 1973.^[7]

The line was extended to Komyoike on 20 August 1977, and to Izumi-Chuo on 1 April 1995.^[7]

Owing to ongoing financial constraints caused by the COVID-19 pandemic, Semboku Rapid Railway announced that it would be merged into Nankai Railway.^[8] The merger took place on 1 April 2025.^[9] In addition, the line was renamed to the Semboku Line. Stations were renumbered to NK88 at Fukai through NK92 at Izumi-Chūō.^[10]
