The story
In 1985, the construction and installation union Yamaltransstroy was founded with the aim of constructing railways in the far north of Western Siberia.
In 1986, construction started on the Obskaya-Bovanenkovo railway line with a length of 509 km to the gas condensate deposits at Kharasavey Cape. The track is located completely beyond the Arctic Circle in permafrost conditions, and is one of the most difficult railway tracks due to geological, climatological and natural conditions.
In 1992, the enterprise became a joint-stock company.
In 2009, the company completed the construction of a 4-kilometre bridge crossing the River Yuribey (334th km of the track), one of the most difficult engineering facilities beyond the Arctic Circle.
By 2010–2011, the track was practically completed and revenues of the company fell by half, reduced to 9.4 billion roubles in 2010.
