The project will be funded through a private investors under a concession scheme. RZD, Gazprom and Yamalo Nenets Autonomous Okrug, the main participants, will upgrade the existing infrastructure while the new facilities will be built by SPC-Concessionaire, a subsidiary of RZD.

SPC-Concessionaire will finance, build and operate the Obskaya - Salekhard - Nadym line, with a particular focus on the bridge across the Ob River, the bridge across the Nadym River, and the new 353km Salekhard - Nadym section.

RZD will reconstruct the adjacent Konosh - Kotlas - Chum Labytnangi sections of the Northern Railway as well as the Ob station and the Pangody - Novy - Urengoy - Korotchaevo line of the Sverdlovsk Railway.
