1. Characterization of train-induced aerodynamic loads on high-speed railway vertical noise barriers
Abstract : High-Speed Railway (HSR) technology requires the deployment of noise barriers to mitigate noise pollution affecting nearby residents. As train speeds increase, so does the magnitude of aerodynamic effects such as aerodynamic noise and the pressure on these barriers, meaning that these structures require robust sound insulation and structural load-bearing capacities.

2. Introduction of regional high speed trains : A study of the effects of the Svealand line on the travel market, travel behaviour and accessibility
Abstract : The Svealand line opened in 1997 and the services areoperated with regional high speed trains. While the Svealandline was being built, the slow trains that had been inoperation on the old railway between Eskilstuna and Stockholm(a distance of 115 km) were replaced by buses with a highfrequency of service.

3. Vibration mitigation of high-speed railway bridges : Application of fluid viscous dampers
Abstract : At the moment of writing, an expansion of the Swedish railway network has started, by constructions of new lines for high-speed trains. The aim is to create a high-speed connection between the most populous cities in Sweden - Stockholm, Göteborg and Malmö, and the rest of Europe. READ MORE

4. Vibration mitigation of high-speed railway bridges : Application of damping devices in theory and practice
Abstract : The dynamic response of railway bridges is an important aspect to consider, as the repetitive loading from passing trains may result in excessive vibrations of the bridge deck. Several design criteria are developed in order to assure the structural safety and passenger comfort during train crossings of a bridge. READ MORE

5. Simplified dynamic analysis of railway bridges under high-speed trains
Abstract : The world-wide development of new high-speed rail lines has led to more stringent design requirements for railway bridges. This is mainly due to the fact that a train at high speeds can cause resonance in the bridge superstructure. READ MORE
