Szukana fraza: [Abstrakt = "This paper presents a new approach to widening of intertrack space. A thesis was formulated that the widening should be formed using two combined curves with appropriate distribution of curvature along its length. On the length of the widening in the extreme zones of the two curves the sections of the variable curvature were assumed. However, the curvature in the central zone was taken as constant. To solve the issue the analytical method of designing was used. An identification of the curvature distribution was implemented through differential equations and mathematical description of ordinates in the individual zones of the curve widening. Two cases of variable distribution curvature were considered\: linear and non\-linear \(polynomial\). Obtaining a specific ordin ate of the final widening requires sequential correction of adopted geometrical parameters."]
