Russian Railways begins construction of new Kerak tunnel on Trans-Sib in Amur Region
Russian Railways has begun the construction of the new Kerak tunnel on the Ulruchi - Kovali section of the Trans-Siberian Railway in the Amur Region.
The 910-metre long tunnel currently in operation was built in 1910-1911, but is now too small.
The new tunnel will increase the train speed and throughput on this section. At 926 metres, it will be the longest tunnel on the Trans-Baikal Railway.
The design solutions have received a positive conclusion from Russia’s Federal Autonomous Institution Glavgosexpertiza [Main Department of State Expertise] and provide for the construction of a new double-track railway tunnel about 25 metres from the existing one. Upon completion of construction, the current tunnel will be used as an evacuation and drainage facility.
In addition, the railway modernisation plans for Eastern Russia include several projects for the reconstruction and construction of tunnels. This year the second stage in the reconstruction of the tunnel under the Amur River near Khabarovsk will be completed.
