Background: Transport is a sector of the economy that is subject to general economic laws, including with regard to issues related to investing in real assets, developing means of production, and ensuring expanded reproduction. Along with this, transport is a strategic sector at the state level, ensuring the functioning of the economy as a whole. In this regard, there are certain contradictions associated with the assessment of the effectiveness of investments in transport infrastructure. In most cases, investments in transport infrastructure are valued similarly to investments in a business project. After the issuance of Decree of the Government of the Russian Federation No. 1512 dated November 26, 2019, the approach to evaluating the effectiveness of investments with state participation has expanded, but it does not fully cover the issues of project effectiveness for the state. Along with this, the classical methods for evaluating the effectiveness of investment projects are subject to great subjectivity in relation to the calculation of social effects, as a result of which their applicability to projects at the national economic level is ineffective.
 Aim: to consider the list of effects arising from the construction of transport infrastructure and determine the methodology for calculating the effects for the state.
 Materials and methods: the research methodology is based on the analysis of methods for financial and economic evaluation of investment projects, as well as macroeconomic methods. The information base of the study is based on the official legal and methodological information of the authorities of the Russian Federation.
 Results: as a result of the study, a list of effects for the state arising from the implementation of transport infrastructure development projects was determined, and the procedure for their calculation was substantiated.
 Conclusion: the study confirms that the currently used methods for evaluating the effectiveness of investments in infrastructure projects for the state do not fully and objectively reflect economic realities. The proposed approach to the assessment will make it possible to carry out a comprehensive assessment of the socio-economic effects from the construction of cargo maglev transport lines and improve the quality of management decisions in the transport sector.
