It is the only submarine construction on the Russian Railways.The Tunnel construction project under Amur arose in connection with the construction of the Trans-Siberian Railway. In 1913, at the exhibition of the Amur Region, there was a drawing of the tunnel, but the choice had already been made in favour of the bridge.In the 1930's the Transsib construction of a second track on the eastern section was conducted. The need to build the tunnel was caused by the Japanese invasion of Manchuria in 1931, the loss of the CER and, accordingly, the vulnerability of the bridge. In 1936, because of the particular strategic importance for the country Trans, it was decided to build with the initiative of the General Staff of the Red Army.The technical design of the underwater 7,198 metre long tunnel was designed in 1937 by the Institute Metroproject(ru), which was then in the People's Commissariat of Communications of the USSR7 km long railway had been covered with five boards, 3627 m long mountain way (three faces) in the eastern sector, 1350 m open way in the western section and internal diameter tunnel - 7400 mm for underwater. Semi-manufactured crushed stone, construction of houses and other surface structures of transition were constructed by Railway Troops(ru).
