“…An existing scientific literature review was carried out to compile the list of criteria. It was indicated that the main targets of the infrastructure modernization are optimal infrastructure capacity (Gašparík et al, 2018), traffic safety level (Meijer et al, 2009), passenger and freight train speed (Lebid et al, 2019;Brezina & Knoflacher, 2014;Ižvolt & Hodas, 2012). It was noted as well that all main infrastructure parameters should be applied in a comprehensive system model to provide the optimum infrastructure design and capacity (Connor, 2014).…”

“Rail Baltica” project is priority project No 27 “Rail Baltica” axis Warsaw-Kaunas-Riga-Tallinn-Helsinki, approved by Decision No 884/2004/EC of the European Parliament and of the Council of 29 April 2004 amending Decision No 1692/96/EC on Community guidelines for the development of the trans-European transport network (European Union, 2004). An article analyzes the changes in the main parameters of the 1435 mm gauge railway infrastructure during the whole period of the “Rail Baltica” project, determines their impact on the project implementation time-line, purposes and results, highlights basic parameters which need to be met during modernization. On this basis, the main criteria for the evaluation of Rail Baltica rail infrastructure were selected. An expert survey was conducted to evaluate the criteria. The Kendall method was used to calculate the criteria weights. The article ends with a scientific discussion.

Purpose. The work is aimed to reduce the intensity of the track disorder by improving the line plan parameters, ultimately ensuring the safety, smoothness and comfort of driving in the directions of high-speed train traffic. Methodology. To obtain initial data on the parameters of the plan of existing railways, the authors reviewed the world literature on the topic of the study, as well as monitored the railway track operation on the basis of technical passports of track distances. It is known that the accepted mathematical models of the existing plan use the assumption that three adjacent points of the curve lie on a circle. On this principle, the work of flattener machine for switches is based. As a result of corrective works to reduce the amount of shifts, the curve does not correspond to the initial passport data. The methodology involves the analysis and systematization of data to establish appropriate dependencies and build graphs. Findings. Inaccurate determination of the curve parameters results in unjustified speed restrictions on or large volumes of flattening works. Therefore, the proposals have been developed to reduce the intensity of track disorders by bringing the curve parameters to the regulatory requirements in force in Ukraine in the areas of high-speed train traffic. They follow from the analysis of the method of shooting curves used in track distances. The influence of accuracy of the obtained data on the establishment of the curve parameters and the permissible train speeds is identified. The recommendations received in the work will contribute to the effectiveness of design decisions, will determine the quality of the railway reconstruction project. Originality. Scientific approaches to estimating the state of curves, determining their rational parameters and permissible speed in the areas of high-speed train traffic in Ukraine have been further developed. Practical value. The obtained results will be useful for measures to improve the smoothness of train movement, increasing the speed and comfort of driving in the curved track sections, especially in the areas of high-speed train traffic.
