Selected problems of determining the course of railway routes by use of GPS network solution
PublikacjaW 2009 roku Politechnika Gdańska rozpoczęła prace nad wykorzystaniem ciągłych pomiarów pozycji systemów geodezji satelitarnej dla wyznaczania przebiegu trasy kolejowej z wykorzystaniem fazowych metod GPS opartych o serwis NAVGEO polskiej Aktywnej Sieci Geodezyjnej ASG-EUPOS. W celu eliminacji błędów przypadkowych wpływających na dokładność wyznaczenia trasy kolejowej w następnym roku zespół przeprowadził dwie kampanie pomiarowe...

Railway noise problems in Poland
PublikacjaCelem referatu jest przedstawienie zagadnień związanych z hałasem kolejowym. W pierwszej kolejności podano przegląd badań związanych z hałasem kolejowym, które są prowadzone w polskich ośrodkach i instytucjach naukowych. Przytoczono również główne modele hałasu kolejowego zawarte w dyrektywach europejskich (projekty HARMONOISE i IMAGINE). Dodatkowo zaimplementowano wybrane modele hałasu kolejowego dla warunków polskiego taboru...

Problems of Railway Noise-A Case Study
PublikacjaUnder Directive 2002/49/EC relating to the assessment and management of environmental noise, all European countries are obliged to model their environmental noise levels in heavily populated areas. Some countries have their own national method, to predict noise but most have not created one yet. The recommendation for countries that do not have their own model is to use an interim method. The Dutch SRM II scheme is suggested for...

Computer application for railway track realignment
PublikacjaThe topic of this article is the issue of railway track realignment. For this purpose, a computer software application was created that supports computations and generates a report needed for regulation of the trajectory of the railway. This program gives the ability to import data from measurement of the railway trajectory and then perform the calculation of the mathematical realignment. The result of this calculation is the basis...

Prospects in elongation of railway transition curves
PublikacjaThe paper presents an analysis of the elongation of transition curves in relation to railway track alignment correction and modernisation. The analysis is based on numerical computations for a wide range of parameters describing a typical railway geometrical layout with transition curves. The differences between the horizontal ordinates of the existing layout and the layout with the elongated transition curves are evaluated and...

Monitoring of current collectors on the railway line
PublikacjaProper cooperation the current collectors and the overhead line is a pre-requisite for reliable and safe operation of railway transport. Instances of maladjustment and, in some cases, damage to the current collectors, occur between periodic inspections of the rolling stock. In order to detect such anomalies quickly, the test stand was developed, with the aim of monitoring the technical state of the current collectors under operating...

Mobile satellite measurements on the Pomeranian Metropolitan Railway
PublikacjaThis paper presents the process of organization and execution of the mobile satellite measurements conducted on the tracks of the Pomeranian Metropolitan Railway before officially entry the line into operation. These measurements allowed for the accurate identification of the actual geometric shape of the line. In the paper the issues of both design and construction phase of this railway line has been described. Moreover, the geodetic...

Arching of railway turnouts by analytical design method
PublikacjaThe 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...

Costs of upgrading based on 131 railway line
PublikacjaW poszukiwaniu optymalnego wykorzystania środków finansowych przedsiębiorstwa kolejowego (PKP PLK) oraz czasu planowania napraw torowisk stworzono model trwałości toru. Model w swych założeniach opiera się na parametrach techniczno – eksploatacyjnych linii kolejowej nr 131. W artykule przedstawiono dwa warianty procesu trwałości toru. Pierwszy wariant zakłada oczyszczenie toru, drugi przeprowadzenie modernizacji. Dla obu wariantów...
