  1. 1. Optimization model for selection of switches at railway stations

    University essay from Linköpings universitet/Tillämpad matematik; Linköpings universitet/Tekniska fakulteten

    Author : Sam Olsson; [2021]
    Keywords : Railway station design; Optimization; Integer programming;

    Abstract : The goal of this project is to implement and verify an optimization model for finding a min-cost selection of switches and train paths at railway stations. The selected train paths must satisfy traffic requirements that commonly apply to regular railway traffic. READ MORE

  2. 2. Risk, Rail and the Region : A spatial analysis of regional differences of infrastructural safety and the risk of accidents at Swedish level-crossings

    University essay from Stockholms universitet/Kulturgeografiska institutionen

    Author : Henning Grauers; [2019]
    Keywords : level-crossings; infrastructural safety; risk; railway;

    Abstract : Level-crossings, i.e. intersections where railways and road meet in the same vertical level, constitute risk for the users of respective infrastructure system. The aim of this thesis is to examine possible regional differences between the infrastructural safety standard of level-crossings in Sweden. READ MORE

  3. 3. The Nordic Prediction Method For Railway Traffic Noise : Improvements of the current corrections forrailway bridges, switches and crossings

    University essay from KTH/Byggnadsmaterial; KTH/Byggnadsmaterial

    Author : KRISTÍN HELGADÓTTIR; RAGNHEIÐUR BJÖRNSDÓTTIR; [2019]
    Keywords : The Nordic Prediction Method; Railway traffic; Railway noise; Noise measurements; Acoustics; Steel bridges; Concrete bridges; Switches; Railway crossings; Correction factor; Correction for track condition;

    Abstract : Railway noise is a very important and growing health hazard in today´s society.Railway systems pass through towns and cities and create noise. When trainsride through or over railway bridges, switches and crossings the noise increasessubstantially, causing great annoyance to the residents in the area. READ MORE

  4. 4. Influence of Switches and Crossings on Wheel Wear of a Freight Vehicle

    University essay from KTH/Spårfordon

    Author : Emmanouil Doulgerakis; [2013]
    Keywords : dynamic vehicle-track interaction; turnout; switch crossing; wheel wear; wheel-rail contact geometry;

    Abstract : Turnouts (Switches & Crossings) are important components in railway networks,as they provide the necessary flexibility for train operations by allowing trains tochange among the tracks. But the turnout’s geometry with discontinuity in railprofiles and lack of transition curve causes additional wear both on track and onvehicle. READ MORE

  5. 5. Dynamic analysis of soil-steel composite bridges for high speed railway traffic : Case study of a bridge in Märsta, using field measurements and FE-analysis

    University essay from KTH/Bro- och stålbyggnad

    Author : Peyman Mellat; [2012]
    Keywords : Soil-Steel Composite Bridge; Flexible Corrugated Steel Culvert; Structural Dynamics; Acceleration; High-Speed Trains; Field Measurement; FEM;

    Abstract : Soil-steel composite bridge refers to structures where a buried flexible corrugated steel pipe works in composite action with the surrounding soil. These structures are being increasingly used in road and railway projects as an alternative to standard type bridges, e.g. short- and medium span concrete beam- and portal frame bridges. READ MORE
