In April 2008, Russia and North Korea signed a long-awaited deal to rebuild the railway line to North Korea. Under the deal, the two countries will renovate the rail line from Russia's border town of Khasan to the North Korean port of Rajin, where sea cargo to and from South Korea could be unloaded. To implement the project, the Russian Railways Trading House and the Port of Rajin set up a joint venture. It will ensure investments in the project, as well as employing contractors for design and construction work. The joint venture is to last 49 years, with 70 percent of the shares belonging to Russia and 30 percent to North Korea. Russian railwaymen began renovating the Khasan-Rajin railway section in October 2008, and a demonstration train ran on the Rajin-Khasan route in October 2011. By the following February, a new dual gauge with the length of 32 kilometres has been laid at the Rajin-Khasan section, complete overhaul of 20 kilometres of the tracks has been made, railroad switches and tracks were installed, a number of stations reconstructed, the work in the tunnels was started, trunk telecommunication lines and electrical interlocking lines were stretched and drainage structures restored. Coal transport from North Korea started in summer 2014.
