1. Opportunities with Modular Systems in Level Crossings : A Case Study in the Swedish Railway Industry
University essay from KTH/Skolan för industriell teknik och management (ITM)Abstract : 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. Evaluation of load distribution on ballasted reinforced concrete railway trough bridges
University essay from Luleå tekniska universitet/Byggkonstruktion och brandAbstract : 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. Reliability-Based Sensitivity Analysis of the Dynamic Response of Railway Bridges
University essay from KTH/Bro- och stålbyggnadAbstract : In response to the planned increase in operational speeds and axle loads of passengertrains that may lead to resonance-induced excessive vibrations in railway bridges,recent studies examined the reliability of bridges concerning train running safety andpassenger comfort limit states. In this respect, valuable information regarding theimportance of input variables can be obtained by conducting Sensitivity Analysis (SA). READ MORE
