The Namsos Line ((ノルウェー語:Namsosbanen)) is a long railway line between Medjå and Namsos in Nord-Trøndelag, Norway. The line branched off from the Nordland Line at Grong Station and runs through the municipalities of Grong, Overhalla and Namsos, largely following, and twice crossing, the river of Namsen. The section from Grong to Skogmo is maintained, although not used for ordinary traffic. The section from Skogmo to Namsos is closed, but the infrastructure remains. Planning of the line started in the 1870s and it was originally thought as part of the Nordland Line. This resulted in a debate of whether the Nordland Line should run from Steinkjer via Beitstad and Namsos to Grong (the Beitstad Line) or via Snåsa to Grong, with a branch to Namsos. The latter was selected as it gave the shortest route for the Nordland Line, but gave a longer distance southwards from Namsos and went through a less densely populated area. The line was passed by Parliament in 1913, although construction did not start until 1921. In 1927, construction was halted, but resumed the following year, although the line was built with substandard permanent way. Passenger traffic was terminated in 1977, and the line has been closed for ordinary traffic since 2002. ==Route== The Namsos Line branches from the Nordland Line at Grong and runs to Namsos. Prior to 1981, the line had a different terminus in Namsos and was long.〔Bjerke (1994): 106〕 The curve radius is and the maximum gradient is 1.25 percent.〔Aspenberg (1994): 274〕 The line has five tunnels,〔Aspenberg (1994): 275〕 with a combined length of .〔Aspenberg (1994): 275〕 The line is standard gauge, non-electrified,〔 lacks centralized traffic control,〔Norwegian National Rail Administration (2009): 37〕 automatic train control,〔Norwegian National Rail Administration (2009): 40〕 and train radio.〔Norwegian National Rail Administration (2009): 42〕 The railway line is owned and maintained by the Norwegian National Rail Administration.〔Norwegian National Rail Administration (2009): 3〕 The section from Grong to Skogmo, Overhalla, remains open and maintained, but is not used for ordinary traffic. The section from Skogmo to Namsos remains, but is not maintained. After Grong Station, which is located from Trondheim Central Station and above mean sea level (AMSL), the line runs over Tømmeråsfoss on the long Sanddøla Bridge and then over the long Røttesdal Vidaduct. The line then runs past Dun Station ( from Grong Station), before Sjemsvoll Station () and Jørem Station (). Next the line reaches Øyheim Station (), which has a passing loop. The line then passes into Overhalla and continues to Øysletta Station (), before crossing to the north shore Namsen on the long Bertnem Bridge.〔Bjerke (1994): 107〕 It passes Heknbakk Station () before Skogmo, where there is an industrial spur.〔 This is the end of the part of the line which remains open to traffic.〔 The line then reaches Skogmo Station (), which has a passing loop. It then crosses Namsen on the long Bjøra Bridge and reaches Himo Station (). The line then reaches Overhalla Station (), which has a passing loop and serves the municipal center of Ranemsletta.〔 The line continues on a long bridge over Reina before reaching Barlia Station (), Øysvoll Station (), Myrmo Station () and Halvardsmo Station (). An industrial spur then branches off before the main line reaches Skage Station (), which has a passing loop. The line crosses a long bridge over Myrelven before passing through the long Bergeng Tunnel and the long Brudalsøy Tunnel.〔 Next the line reaches Grytøya Station () before running through the long Vika Tunnel. It continues past Kvatninga Station () and then over Moeosen on a long bridge. Next it reaches Meosen Station (), Høyknes Station () and Angelskjæret Station (). The line then runs through the long Hønhaugen I Tunnel and the long Hønhaugen II Tunnel. Originally the line went to the old Namsos Station ( from Grong and AMSL), but since 1981, the line has been shortened to terminate at the new Namsos Station ().〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Namsos Line」の詳細全文を読む スポンサード リンク
