The problem of dividing the investments into development of railway transport systems is formulated as a linear programming problem. As the objective function for the optimization problem, we propose to use the sum of private performance indicators characterizing resource saving, the environmental component of functioning, the social component, and the quality of customer service. The vector of control variables in the proposed formulation is the set of investments shares for the considered directions of sustainable development, and the vector of the objective function coefficients contains functions of investments elasticity for the respective directions of the railway system sustainable development. As far as the objective coefficients depend on the number of productive resources (number of locomotives and handling mechanisms at the stations) and parameters of demand for transport services, computer simulations should be used for estimation of the objective function. The paper briefly describes the developed software for simulations of railway transport systems and solving the presented linear programming problem.
