1. Interpretation of Railway Track Alignment Measurements in a Geodynamic Perspective
Abstract : The development in society means that infrastructure like ballasted railway systems are facing challenges due to request for increased number of high-speed trains and heavier freight trains. This implies that ballasted railways get an increased impact from larger dynamic loads. READ MORE

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

3. Concrete Bridges : Improved Load Capacity
Abstract : There are many beautiful old structures around the world, some of which were designed for completely different purposes than their current applications. For example, Swedish railway bridges were only designed to carry axle loads up to 200 kN in the beginning of the 20th century, while modern loads can be twice as high. READ MORE

4. Preliminaries for probabilistic railway sleeper design
Abstract : Two investigations are presented, which can be seen ascontributions to the aim of introducing a probabilistic designstrategy of railway sleepers in the future. When usingprobabilistic design the statistics of all relevant parametersconsidered as stochastic must be known. READ MORE

5. Analysis of traffic load effects an railway bridges
Abstract : The work presented in this thesis studies the load and loadeffects of traffic loads on railway bridges. The increasedknowledge of the traffic loads, simulated using fieldmeasurements of actual trains, are employed in a reliabilityanalysis in an attempt at upgrading existing railwaybridges. READ MORE
