The first tunnel of the running line between Novatorskaya and Akademicheskaya on the Troitskaya Line has been completed

“The ‘Marina’ tunnel boring machine (TBM) completed driving of the left running tunnel between the Vavilovskaya and Akademicheskaya stations on the Troitskaya metro line”, said Andrey Bochkarev, Deputy Mayor of Moscow on Urban Planning and Construction.

Mosinzhproekt Group of Companies is a general designer and general contractor to construct the new lines and stations of the Moscow Metro.

“The ‘Marina’ TBM tunnelled the left running tunnel between the Vavilovskaya and Akademicheskaya stations under construction of the prospective Troitskaya Line. The TBM covered 2,470 metres of track in the conditions of dense urban development”, said Andrey Bochkarev.

According to the Deputy Mayor, the tunnel route went under the alley on the odd side of Leninsky Prospekt, the roadway of Dmitry Ulyanov Street and the existing Akademicheskaya station of the Kaluzhsko-Rizhskaya Line.

Yuri Kravtsov, General Director of Mosinzhproekt JSC, added that ‘Marina’ had previously been used in the tunnelling of the eastern BCL section and the inter terminal pedestrian tunnel at Sheremetyevo Airport.

“A total of five tunnel boring machines are operating on the central section of the prospective Troitskaya Line with the ZIL, Krymskaya, Akademicheskaya, and Vavilovskaya stations: ‘Olga’ is tunnelling the adjacent right tunnel, ‘Alexandra’ and ‘Sofia’ are connecting the ZIL station with the Krymskaya station, and ‘Natalia’ and ‘Svetlana’ are connecting Krymskaya with Akademicheskaya”, specified Yuri Kravtsov.

The head of the engineering holding specified that both tunnels between Vavilovskaya and Novatorskaya had already been completed and all four station complexes of the section were in the active stage of construction.

The Troitskaya metro line, being 40 km long, will connect the platforms of the Moscow Central Circle (MCC) with the city district of Troitsk, going through the Southern, South-Western, Troitsky and Novomoskovsky districts of the capital city. The expected daily passenger traffic flow is somewhat 100 thousand people. About 1 million people live near the new stations, and several hundred thousand more work or study nearby.
