1. Brobanor och dess egenskaper för kommande höghastighetsjärnväg : Brobanors användning och egenskaper i samband med höghastighetsjärnväg
Kandidat-uppsats, KTH/Byggteknik och designSammanfattning : SammanfattningSvensk järnväg har aldrig varit mer belastad och trafikerad än idag, och värre kommer det att bli. Det har inte pågått några större investeringar i svensk järnväg sen 1990-talet, effekterna av den strategin börjar bli alltmer uppenbar. LÄS MER
2. Opportunities with Modular Systems in Level Crossings : A Case Study in the Swedish Railway Industry
Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)Sammanfattning : Level crossings are a dangerous part of railways, causing several deaths every year. While the safest solution is to remove crossings altogether using bridges or tunnels, this is complicated and cannot be done on a large scale. Many level crossings will therefore continue to exist.

3. Dynamic Analysis of Portal Frame Bridges for High-Speed Trains : A Parametric Study
Master-uppsats, KTH/Bro- och stålbyggnadSammanfattning : A high-speed railway network is important for Sweden’s development. However, anincreasing train speed brings new challenges in bridge design due to higher bridgeaccelerations. LÄS MER
4. Evaluation of load distribution on ballasted reinforced concrete railway trough bridges
Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Byggkonstruktion och brandSammanfattning : A significant portion of the reinforced concrete railway bridges in Sweden are reaching their designed lifespan and are scheduled to be demolished and replaced in the upcoming years. To limit the econom-icand environmental impact related to the replacement of existing railway infrastructure, a comprehen-siveevaluation of their capacity is required with the aim of extending its lifespan.

5. Improved Bridge Load Capacity via Dynamic Train-Track-Bridge Interaction : Assessing the dynamic amplification factor caused by measured track irregularities for rail freight transport
Master-uppsats, KTH/Bro- och stålbyggnadSammanfattning : The carbon impact of transportation is large and requires sustainable solutions. With expected population growth, rail transportation plays a vital role in facilitating a greener Europe. The expansion of the rail infrastructure is therefore of essential importance for future challenges. LÄS MER
