Ishinomaki Line

The Senpoku Light Railway opened a 762 mm (2 ft 6 in) gauge line from Kogota to Ishinomaki in 1912. The line was nationalised in 1919 and converted to 1,067 mm (3 ft 6 in) gauge in 1920. The Oshika Light Railway opened a 762 mm (2 ft 6 in) gauge horse-drawn tramway from Ishinomaki to Watanoha in 1915, and extended it to Onagawa in 1924. A petrol-driven locomotive was introduced in 1926. The line was nationalised in 1939 and converted to 1,067 mm (3 ft 6 in) gauge the same year.^{[citation needed]}

In 1958, the line was extended 1.4 km (0.87 mi) to the Onagawa Port, but that extension closed in 1980.^{[citation needed]}

The line was severely damaged by the 2011 Tōhoku earthquake and tsunami on 11 March 2011; the Kogota - Ishinomaki section being out of service for two months, the Ishinomaki - Watanoha section for a year, and the Watanoha - Urashuku section for two years. The final section from Urashuku to Onagawa reopened on 21 March 2015.^[1]
