• Analytical design method for widening the intertrack space

  Publikacja

  • W. Koc

  - Current Journal of Applied Science and Technology (British Journal of Applied Science & Technology) - Rok 2019

  The paper involved the issue of arching of the railway turnouts. This is an issue which is given relatively less attention to scientific and research activities. Reference has been made to the book by Wladyslaw Rzepka, under the title „Curved turnouts in plan and profile”, which has been used in Poland for more than 50 years as the main source of information relating to the turnouts on the curve. The book is a compilation of elaborations...

• Transition curve with smoothed curvature at its ends for railway roads

  Publikacja

  • W. Koc

  - Current Journal of Applied Science and Technology (British Journal of Applied Science & Technology) - Rok 2017

  In the paper, in view of a railway ballasted track, a new concept of transition curve of linear form of curvature along its length and smoothed extreme regions is presented. For this purpose use has been made of an original, universal method for identifying transition curves by means of differential equations. Some general curvature equations for three regions investigated have been determined to be followed by appropriate parametric...

  • C. Specht
  • P. Chrostowski
  • K. Palikowska

  - Current Journal of Applied Science and Technology (British Journal of Applied Science & Technology) - Rok 2016

  Designing of the track’s alignment is a key issue from the point of view of maintaining of proper geometries. The paper presents a design method for sections of railway line located in the horizontal arch. The method is adapted to the technique of mobile satellite measurements. The general principles of this measurement method have been described in the article. A project's solution has been presented using mathematical notation...
