The is a railway line in the Tōhoku and Chūbu regions of Japan. Part of the East Japan Railway Company (JR East) system, it connects Niitsu Station in the city of Niigata and Akita Station in Akita. The name "Uetsu" refers to the ancient provinces of Dewa (出羽) and Echigo (越後), which the line connects. ==History== The line was opened in sections between 1912 and 1924, and electrified in 1972, the same year CTC signalling was commissioned. Work to duplicate the line in sections commenced in 1957, and continued for 25 years until being suspended due to capital expenditure restrictions in 1983, at which time 51% of the route was duplicated, although the longest continuous duplicated section is 27.3km. In many sections the track is located on a narrow shelf between the ocean and adjacent mountains, meaning duplication often required constructing long tunnels on the inland side of the original line to accommodate the second track. The completed work includes 11 tunnels each over 1km long (the longest being 2.3km), and the suspension of works resulted in the completed tunnel between Koiwagawa and Atsumi Onsen stations remaining unused.
