1. 11. Analys av den europeiska nattågstrafikens tillbakagång och framtidsutsikter - Historik, nedläggningsorsaker, framgångsfaktorer och lärdomar

   Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Trafik och väg

   Författare :Mikael Thorsén; [2018]
   Nyckelord :Nattåg; nedläggningsorsaker; ÖBB; nischer; framgångsfaktorer; Technology and Engineering;

   Sammanfattning : This thesis concerns the last decade’s considerable decline in western European night train traffic. First, the context of the study is presented with a brief overview of climate challenges, liberalization of the railway market within the European Union and theoretical aspects of demand for night train traffic.

3. 12. Decision-making model for track system of high-speed rail lines : Ballasted track, ballastless track or both?

   Master-uppsats, KTH/Byggvetenskap

   Författare :Veronika Sárik; [2018]
   Nyckelord :;

   Sammanfattning : During the 50 years of existence of high speed railways, the track structure solutions have developed both in number and in type. As of today, in case of conventional railway, there are 2 main types one could mention: ballasted and ballastless track solutions. LÄS MER

4. 13. Markanvändning vid byggnation av höghastighetsjärnväg; en jämförelsestudie mellan höghastighetsjärnväg på bank och höghastighetsjärnväg på viadukt.

   Kandidat-uppsats, Lunds universitet/LTH Ingenjörshögskolan vid Campus Helsingborg

   Författare :Niclas Andersson; Hamzeh Hassoun; [2017]
   Nyckelord :höghastighet; järnväg; markanvändning; ostlänken; Technology and Engineering;

   Sammanfattning : In the construction of high-speed railways, an important starting point is to make as little Intrusion on land as possible, therefore it is of high importance to carefully investigate which construction alternatives are the most advantageous. The purpose of this work is to compare and evaluate land use and building on viaduct. LÄS MER

5. 14. Jämförelsestudie av strategiska stationsplaceringar på Höghastighetsbanan - Värnamo station

   Kandidat-uppsats, Lunds universitet/LTH Ingenjörshögskolan vid Campus Helsingborg

   Författare :David Nguyen; Albin Dahl; [2017]
   Nyckelord :höghastighetsbanan; stationsläge; samhällsplanering; samhällsutveckling; transportsystem; järnväg; Technology and Engineering;

   Sammanfattning : The Swedish railway system has a lack of capacity, which has caused major delays and problems with punctuality. One of the reasons is the increase in rail traffic over the recent decades. To reduce the pressure on existing railways, the Swedish government is planning to construct the first Swedish high-speed rail link. LÄS MER

7. 15. Discrete Element Modelling of the Unbound Layer for Slab Tracks on High Embankment

   Master-uppsats, KTH/Jord- och bergmekanik

   Författare :Karima Ghyate Forsberg; Rogin Ramak; [2016]
   Nyckelord :Slab track; unbound layer; discrete element modelling; deformation; embankment height; friction;

   Sammanfattning : According to Swedish guidelines for high speed railways on embankment, the total settlement is limited to 20 mm over a track length of 10 m during the construction service life. The main objective of this thesis was to investigate the deformation in the subgrade (unbound layer) in a slab track, since there are very few studies related to high speed railways on high earth structure, discussing particularly the unbound layer.
