ABSTRACT Acceleration of economic growth of many countries, including Russia, through formation of a multiplier effect is largely based on successful implementation of investment programs of transport companies. At the same time, a positive trend should be ensured at all stages of the life cycle of each project. To make conceptually verified management decisions that are clearly oriented by economic theory, it is proposed to use dynamic economic and mathematica l models for substantiating large investment projects aimed at developing transport infrastructure. The article considers options to ensure sustainability of a financial result, depending on implementation of the project with different amounts of financing and different degrees of approach of companies to the conditions of investment equilibrium.
