  1. 1. Introduction of regional high speed trains : A study of the effects of the Svealand line on the travel market, travel behaviour and accessibility

    Författare :Oskar Fröidh; KTH; []
    Nyckelord :The Svealand line; high speed trains; regional travel; travel behaviour; choice of transport mode; accessibility; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : The Svealand line opened in 1997 and the services areoperated with regional high speed trains. While the Svealandline was being built, the slow trains that had been inoperation on the old railway between Eskilstuna and Stockholm(a distance of 115 km) were replaced by buses with a highfrequency of service.

  2. 2. Tilting trains : Technology, benefits and motion sickness

    Författare :Rickard Persson; Evert Andersson; Karl Kottenhoff; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tilting trains; motion sickness; ride comfort; running time; track geometry; Vehicle engineering; Farkostteknik;

    Sammanfattning : Carbody tilting is today a mature and inexpensive technology allowing higher speeds in curves and thus reduced travel time. The technology is accepted by most train operators, but a limited set of issues still holding back the full potential of tilting trains. LÄS MER

  3. 3. Tilting trains : Enhanced benefits and strategies for less motion sickness

    Författare :Rickard Persson; Mats Berg; Björn Kufver; Simon Iwnicki; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tilting trains; running time; ride comfort; motion sickness; tilt control; Vehicle engineering; Farkostteknik; Järnvägsgruppen - Gröna tåget; Järnvägsgruppen - Gröna tåget;

    Sammanfattning : Carbody tilting is today a mature and inexpensive technology that allows higher train speeds in horizontal curves, thus shortening travel time. This doctoral thesis considers several subjects important for improving the competitiveness of tilting trains compared to non-tilting ones. LÄS MER

  4. 4. Vibration mitigation of high-speed railway bridges : Application of fluid viscous dampers

    Författare :Sarah Tell; Raid Karoumi; Ülker-Kaustell Mahir; Andreas Andersson; Bill F. Jr. Spencer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dynamics; vibration mitigation; railway bridge; high-speed trains; bridge deck acceleration; passive damping; fluid viscous dampers; retrofit; dynamik; vibrationsdämpning; järnvägsbro; höghastighetståg; brobaneacceleration; passiv dämpning; viskösa dämpare; eftermontering; Byggvetenskap; Civil and Architectural Engineering;

    Sammanfattning : At the moment of writing, an expansion of the Swedish railway network has started, by constructions of new lines for high-speed trains. The aim is to create a high-speed connection between the most populous cities in Sweden - Stockholm, Göteborg and Malmö, and the rest of Europe. LÄS MER

  5. 5. Simplified dynamic analysis of railway bridges under high-speed trains

    Författare :Christoffer Johansson; Costin Pacoste; Raid Karoumi; Jose M Goicolea; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Dynamic; Railway bridge; High-speed train; Moving load; Multi-span beam; Probabilistic;

    Sammanfattning : The world-wide development of new high-speed rail lines has led to more stringent design requirements for railway bridges. This is mainly due to the fact that a train at high speeds can cause resonance in the bridge superstructure. LÄS MER
