  1. 41. Investigate the track gauge widening on the Iron-ore line and suggest maintenance limits

    University essay from KTH/Spårfordon

    Author : Jesper Flodin; [2020]
    Keywords : ;

    Abstract : Iron ore export remains a major player in the Swedish economy to date, with 90% of all iron ore produced in Europe stemming from the relatively small northern country. A large amount of this ore is transported from the mines to harbours for world-wide freight on railways. READ MORE

  3. 42. An Analysis of Fossil-free Alternatives for Swedish railway

    University essay from KTH/Transportplanering

    Author : Martina Komuhendo; Yuanjian Zhai; [2020]
    Keywords : fossil-free alternatives; railway; costs; environmental impact; AHP; Sweden.;

    Abstract : The transport sector is a major contributor to the rise in global temperatures and emissions. The use of fossil fuel being one of the main drivers, most modes of transport are looking at alternatives to the limited and environmentally unsustainable fuels. READ MORE

  4. 43. Simulation of railway infrastructure with asphalt layer for tracks in Sweden

    University essay from KTH/Byggvetenskap

    Author : Aleksandra Kuksova; [2020]
    Keywords : Ballasted track; bituminous mixture; bituminous sub-ballast; temperature; railway track modelling; finite element analysis. v;

    Abstract : With the introduction of high-speed trains over the past few years, as well as withan increase in traffic loads and volumes, the attractiveness and competitiveness ofthe railway transport system have increased. This leads to the need to develop newcost-effective ways in railway construction, providing an increase in the life cycle ofthe railway track and reducing the need for maintenance. READ MORE

  5. 44. Not everything that glitters is gold : does linear infrastructure create an ecological trap for golden eagles?

    University essay from SLU/Dept. of Wildlife, Fish and Environmental Studies

    Author : Michelle Etienne; [2020]
    Keywords : HIREC; animal ecology; animal movement; animal behaviour; integrated step selection function; wildlife traffic accidents; maladaptive behaviour; fitness; habitat selection;

    Abstract : Animals can be caught in an “ecological trap” when they select for seemingly attractive habitats at the expense of their fitness. This maladaptive behaviour is often a consequence of human induced rapid changes in their natal environment, such as the development of linear infrastructure, where roads and railways create novel feeding conditions through traffic induced mortality of other species and powerline areas provide perching or nesting sites.

  6. 45. A 3D sliding bearing finite element based on the Bouc-Wen model : Implementation in Abaqus

    University essay from KTH/Bro- och stålbyggnad

    Author : Rémi Lantoine; [2020]
    Keywords : Railway bridge; dynamics; resonance; sliding bridge bearings; finite element; Abaqus; friction; steel; Teflon; PTFE; Bouc-Wen model; friction coefficient; temperature; heating;

    Abstract : As rail transportation is significantly more virtuous than airplanes or cars in terms of greenhousegases emissions, its development is being encouraged in several European countries, includingSweden. In addition, the development of railway lines on which trains can travel at higher speeds ismade in Sweden with the integration of existing infrastructure. READ MORE
