Reconstruction of two traction substations on the Mezhdurechensk – Taishet section is completed

A large–scale reconstruction of the Sayanskaya and Krupskaya traction substations (Rybinsky and Minusinsky districts of the Krasnoyarsk Region) has been completed on the Mezhdurechensk – Taishet section, which is the southern track of the Krasnoyarsk railway. Power facilities were modernized as a part of the project aimed at increasing the carrying capacity of the Artyshta – Mezhdurechensk – Taishet section included in the Yenisey Siberia CIP.

New electrical equipment of domestic production was installed at the Sayanskaya and Krupskaya substations, while the working conditions of the staff were made comfortable. Sayanskaya traction substation was completed almost from scratch in accordance with modern requirements and standards. It is equipped with powerful autotransformers, microprocessor protection devices and dispatch control facilities.

It should be noted that gaining of the power supply system on the Mezhdurechensk – Taishet section is being carried out simultaneously with the construction of the second main tracks on single track running lines.

“This allows us to increase the working and carrying capacity of the southern track. We can achieve this developing heavy haul of trains with a mass of 7,100 tons or more in the eastern direction, as well as reducing the running interval by 2 times. The project is of great importance for the Krasnoyarsk Region, Khakassia, Kemerovo Region and other regions where the demand for cargo transportation to the East is growing,” said Alexey Tumanin, head of the Krasnoyarsk Railway.

Total investment of Russian Railways JSC in the reconstruction of Sayanskaya and Krupskaya substations amounted to 1.7 billion roubles. The work was gradually carried out in a short time.

Currently, 6 more substations are being modernized as part of the modernization program of the Mezhdurechensk – Taishet section (Kravchenko, Mana, Krol, Shchetinkino, Koshurnikovo, Kuragino). It is to be completed by the end of 2022.
