Abstract
ENG: Abstract. The problems of railroad design technical reconstruction aimed at ensuring train protection in
introduction of high-speed traffic on the rail lines have been addressed. The description of railroad
technical system with certain specific features has been proposed. The pair of mutually dual problems
regarding the optimal reconstruction of railway curves for raising train speeds at minimal capital
investments has been addressed. The problem of determining the optimal speeds of trains of each category
under optimum outer rail cant, increase of the unbalanced acceleration value, compliance with the
condition of uniform load on rail tracks, comfortable carriage of passengers, in which reduced costs on
increased speeds in curved tracks will be minimal has been formulated. To achieve the goals of the study,
mathematical optimization techniques and algorithms of analysis of the rail lines of different nature are
used. This, by finding and value engineering optimization, allows to minimize high-value and lengthy
procedures of physical simulation. As a problem-solving technique, Lagrange multiplier method and its
applicability have been proposed. Numeral solution to the problem of selection of certain stretches for
increasing rolling stock speeds on operating lines without reconstruction or with minimum expenses on
reconstruction of contour of track has been reviewed.
