The paper analyses the causes for the failure of Russian Railways JSC to efficiently influence the economy and social sector in Russia. The authors argue that decentralising of the industry and setting up subsidiary railways as the main profit centres would allow to take Russian Railways to the level of the world’s leading rail carriers.

Keywords: vertically integrated company, Russian Railways.
