Russia's Far East rail upgrade hits milestone with grid-connected substation
A major electrification project is underway in Russia's Far East, covering 870 kilometres of railway between Volochayevka, Komsomolsk-on-Amur, and Sovetskaya Gavan. The latest milestone saw the Selgon traction substation connected to the 220 kV external national grid, marking a key step in the region's rail modernisation.
The electrification scheme, launched in 2023, includes the construction of 15 new traction substations and the upgrade of two existing ones. Among these, the Selgon substation is now linked to the grid and will enter full operation once startup and adjustment work finishes later this year.
As part of the project, 1,700 kilometres of overhead contact wire will be installed across the network. A dedicated service point at Selgon station is also under construction, designed to support maintenance of the overhead system. Expected to open by the end of 2023, it will accommodate staff, mechanised equipment, and necessary materials.
The wider electrification covers two key sections: Volochayevka–Komsomolsk-on-Amur and Komsomolsk-on-Amur–Sovetskaya Gavan. Once complete, the upgrades will improve rail capacity and efficiency in the Khabarovsk Territory.
The Selgon substation's grid connection brings the project closer to completion, with full commissioning planned for 2023. The new infrastructure, including substations and maintenance facilities, will support long-term rail operations across the Far East's expanded electrified network.
