Ainonai

Departure data for this station is not available on this site.

Ainonai Station opened on 18 November 1912 as Kami-Ainonai on the Yūbetsu Light Railway between Nokkeushi (now Kitami) and Rubeshibe. After several changes of line name the station became part of the Sekihoku Main Line on 1 April 1961. On 5 February 1934 the station was renamed Ainonai (2nd) when the original Ainonai became Higashi-Ainonai. Freight handling outside an industrial spur ended on 1 October 1969, and JR Hokkaido inherited the station at the 1987 privatisation, after which full unstaffing followed on 1 April 1992. The station building was rebuilt in 1988, the written form of the name was shortened from 相ノ内 to 相内 on 1 April 1997, and the platform was extended in April 2004 to end door-cuts on regular trains.

Until April 2004 the platform was too short for the regular train sets, so doors on overhanging carriages had to be locked closed — a practice known as 'door-cut' service.
