    Sammanfattning : In Sweden, high-speed railways is a subject for public debate. The first stage of a high-speed train network, Ostlänken between Stockholm and Linköping, is under investigation, and is planned to be trafficked in 2028. The high-speed railway is intended to hold traffic with speeds up to 320 km/h. LÄS MER

  3. 17. High-speed railway embankments : a comparison of different regulation

    Master-uppsats, KTH/Jord- och bergmekanik

    Författare :Angelica Alamaa; [2016]
    Nyckelord :High-speed; railway; embankments;

    Sammanfattning : Swedish transport administration initiated this Master Thesis project and the aim was to compare regulations for the design of high-speed railways from three European countries: France, Germany and Spain. The reason why this is of interest for the Swedish transport administration is the design of the first Swedish high-speed railway, called Ostlänken. LÄS MER

  4. 18. Soil-structure interaction of end-frames for high-speed railway bridges

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Johan Östlund; [2016]
    Nyckelord :Dynamics; SSI; Soil-structure interaction; Soil-bridge interaction; HSR; High-speed railway; Impedance; Receptance; End-frame bridge; Dynamik; SSI; Jord-struktur interaktion; Jord-bro interaktion; HSR; Höghastighetsbana; Höghastighetståg; Impedans; Receptans; Ändskärmsbro;

    Sammanfattning : In this thesis, the influence of soil-structure interaction (SSI) of end-frame bridges for high-speed railways was studied. Impedance functions, representing the SSI, was calculated and analyzed. The impedance functions were applied to end-frame bridge models which were analyzed for use in HSR. LÄS MER

  5. 19. Stationsalternativ för en framtida höghastighetsbana : En simuleringsstudie av spårlösningar och trafikeringsförslag

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Malin Jakobsson; Amanda Lidström; [2016]
    Nyckelord :Höghastighetståg; kapacitetsanalys; SimEvents; järnvägsstation;

    Sammanfattning : The demand of rail travel and transport of goods by train has increased significantly in Sweden during the last decades. Due to the high utilisation level, significant capacity shortages is nowadays common on numerous lines within the railway system causing substantial delays and low punctuality. LÄS MER

  7. 20. The liberalisation of the European Railway Market - Did the railway packages have a statistical significant effect on rail freight in the EU Member States?

    Master-uppsats, Göteborgs universitet/Statsvetenskapliga institutionen

    Författare :Sascha Brose; [2015-12-01]
    Nyckelord :European railways; railway market; railway packages; reforms; liberalisation of a public service; sequential multiple regression;

    Sammanfattning : The European railway market is since 25 years subject to a constant transformation process. The EU’s railway packages, bundles of railway specific legislation, initiate reforms in a sector that was characterised by decade long national fragmentation and a shrinking modal share. LÄS MER
