    Abstract : The railway system is often considered to be an industry where a monopoly occurs “naturally”, which can explain the public ownership and the use of regulations. However, railways in Europe have been subject to reforms during the last three decades. READ MORE

  4. 2. Railway Track Stiffness : Dynamic Measurements and Evaluation for Efficient Maintenance

    Author : Eric Berggren; Mats Berg; Laurent Schmitt; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Railway track stiffness; maintenance; soil dynamics; measurement; simulation; vibration; Vehicle engineering; Farkostteknik;

    Abstract : Railway track stiffness (vertical track load divided by track deflection) is a basic parameter oftrack design which influences the bearing capacity, the dynamic behaviour of passing vehiclesand, in particular, track geometry quality and the life of track components. Track stiffness is abroad topic and in this thesis some aspects are treated comprehensively. READ MORE
