Reconstructed 100 summer tunnel in the Jewish Autonomous Region
The Far Eastern Railway (Far Eastern Railway, a branch of Russian Railways) has opened for traffic after reconstruction the old Obluchensky tunnel in the Jewish Autonomous Region (a section of the Obluchye-Izvestkovaya Trans-Siberian Railway), the company's press service reported.
"The opening of traffic along the reconstructed Obluchensky tunnel significantly increases the carrying capacity of the Transsib towards the seaports of the Pacific coast. This will make it possible to more effectively develop international cooperation with partners from the Asia-Pacific countries for the benefit of the country's economy," said Vladimir Krapivny, chief engineer of the Far Eastern Railway, at the opening ceremony on September 15.
Initially, object entry was planned for the end of 2014. Reconstruction of the tunnel was started in mid-January, was made with the closure of the movement for the entire period of repair. In the course of it, in particular, the double-track tunnel was reorganized into a single-track one, a continuous junction was laid in the tunnel and on the approaches to it, the over-tunnel drainage systems were repaired.
The completed works are the second phase of the reconstruction of the Obluchensky tunnel on the 8193 km of the Obluchye-Izvestkovaya section and are carried out within the framework of the Russian Railways investment program to remove infrastructure restrictions. The first stage - a new single-track tunnel Obluchensky built - was commissioned in November 2013 of the year. The cost of the project is estimated at 4,2 billion rubles.
The old Obluchensky tunnel with a length of 312,3 m was operated for about 100 years. Due to the increase in freight turnover at Transsib, it did not provide the necessary throughput, the speed of movement through the tunnel was limited to 25 km / h.
