  1. 1. Multi-Criteria Analysis of the proposed Hyperloop transport project in Northern Holland

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Yogesh Sane; [2020]
    Keywords : Hyperloop; Multi-Criteria Analysis; Sustainable Transport; Fifth Mode of Transport; Emerging Technology; Hyperloop; Flerkriterieanalys; Hållbar transport; Femte transportsättet; Emerging Technology;

    Abstract : New technological advancements such as the “Hyperloop” touted as “the fifth mode of transport” could be an answer to the problems ailing the current transport industry. Hyperloop consists of transport pods running through low pressure tubes for the high speed(upto 1000 km/hr) transportation of goods and people. READ MORE

  3. 2. 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

  4. 3. Railway bridges with floating slab track systems : Numerical modelling of rail stresses - Dependence on properties of floating slab mats

    University essay from Luleå tekniska universitet/Byggkonstruktion och -produktion

    Author : Daniel Kostet; [2018]
    Keywords : ballasted track; bridge; elastic mat; expansion; finite element method FEM ; finite element analysis FEA ; floating slab mat; interaction; International union of railways UIC ; non-ballasted track; SOFiSTiK; ballasterat spår; ballastfritt spår; bro; dilatationsfogar; finita elementmetoden FEM ; finit elementanalys FEA ; fixerat spår; interaktion; Internationella järnvägsunionen UIC ; SOFiSTiK; vibrationer; vibrationsdämpande matta;

    Abstract : The increased use of continuously welded rails in the railway systems makes it necessary to increase the control of the rail stresses to avoid instability and damages of the rails. Large stresses are especially prone to appear at discontinuities in the railway systems, such as bridges, due to the interaction between the track and the bridge. READ MORE

  5. 4. Landskapet i samband med infrastrukturprojekt : med fokus på utvecklingen av Sveriges höghastighetsjärnväg

    University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)

    Author : Emelie Hansén; [2017]
    Keywords : höghastighetsjärnväg; Ostlänken; landskap; infrastrukturutveckling; fragmentering; barriärer; restyta;

    Abstract : Utvecklingen av höghastighetsjärnvägen i Sverige förväntas medföra omfattande effekter på landskapet. Det kommer ske en strukturförändring som innebär nya, stora barriärer. Tillsammans med befintligt infrastrukturnätverk fragmenteras landskapet ytterligare och allt mindre ytor skapas, som kan kallas restytor. READ MORE

  6. 5. Comparison of ballasted and ballastless bridges for high speed trains

    University essay from KTH/Bro- och stålbyggnad

    Author : David Matos Sánchez; Maša Nikolic; [2016]
    Keywords : High-speed train; concrete bridge; beam bridge; dynamic; 3D dynamic;

    Abstract : The purpose of the project is to investigate the difference in performance between ballasted and ballastless railway bridges dedicated to high speed trains by taking into account both static and dynamic requirements. The main questions are: a) whether choosing a ballastless bridge results in a more slender section due to the lower self-weight b) if the design of bridges for high speed trains is governed by the static or by the dynamic requirements.
