Purpose. The purpose of the work is to determine the directions for improvement the methods of formation of structures of track development of railway stations and their technical and technological assessment. Method. To determine the areas for improvement the methods of forming structures of track development of railway stations and their technical and technological evaluation, it is necessary to analyze the known scientific approaches, identify their weaknesses and strengths. Based on the analysis of these approaches to develop generalized procedures for the formation of rational structures of track development and evaluation of technical and technological parameters of railway stations. To develop the first procedure, it is necessary to choose the optimization criterion. Results. The paper analyzes the known scientific approaches to the formation of structures of track development of railway stations and their technical and technological evaluation. As a result, it was determined that the most effective way to calculate the design parameters of railway stations is to use automated design procedures, effective ways to calculate technological parameters and evaluate design decisions is to use simulation methods. The generalized procedures of formation of rational designs of track development of railway stations and their technical and technological estimation are offered. Scientific and practical significance. Improved procedures for the formation of rational structures of track development of railway stations and their technical and technological evaluation, which in contrast to the existing ones are based on determining the costs of the railway station with the cumulative total for the calculation period or project life cycle. The implementation of rational design solutions will ensure the implementation of the specified size of train and shunting operations of railway stations with a sufficient reserve of capacity and minimum costs. In addition, the results of technical and technological assessment of track development structures can be the basis for adjusting certain requirements for the construction of station necks.
