1332 meters of intrafactory railway tracks have been laid under the construction of Deep oil refinery complex, which is part of the modernization of the Atyrau refinery. The project will change the scheme of car supply and tank cars with reagents, oil and oil products, obtained in the factory and sent to consumers through Tendyk station to replace the existing scheme from Ak Zhaiyk station.

The new scheme eliminates the car supply with oil within the residential areas of Atyrau, located on the north side of the Atyrau refinery. The railway will lie on the south side of the plant, and its length will make 13 km (from Atyrau refinery to Tendyk station).

The second stage of the project is the construction of 681.6 meters driveway. Currently, the construction site is supplied with necessary materials.
