11. Condition monitoring of railway vehicles : a study on wheel condition for heavy haul rolling stock
Abstract : A railway is an energy efficient mode of transport as it uses the low resistance contact between wheel and rail. This contact is not frictionless and causes wear on both surfaces. The wheel-rail guidance is made possible by the shapes of wheel and rail profiles. READ MORE

12. Adhesion in the wheel-rail contact under contaminated conditions
Abstract : Railway vehicles require a certain level of adhesion between wheel and rail to operate efficiently, reliably, and economically. Different levels of adhesion are needed depending on the vehicle running conditions. READ MORE

13. Light-weighting Methodology in Rail Vehicle Design through Introduction of Load Carrying Sandwich Panels
Abstract : Lightweight design in rail vehicles has been important for quite some time. Structures have been optimised to fulfill their purpose and cut unnecessary weight to reach allowable axle loads. Classically this is done by using steel, thin-walled structures, throughout the car body, or, alternatively, power-pressed aluminum profiles. READ MORE

14. On the Influence of Rail Vehicle Parameters on the Derailment Process and its Consequences
Abstract : This thesis aims at systematically studying the possibilities of minimising devastatingconsequences of high-speed derailments by appropriate measures and features in thetrain design, including the running gear. The course of events immediately afterderailments is studied with respect to whether the train stays upright and close to thetrack centre line or deviates laterally with probably serious consequences.

15. The Internalization of External Effects in Swedish Transport Policy - A Comparison Between Road and Rail Traffic
Abstract : Transport is a key factor for economic growth. It has enabled both the economic scale of production and an increase in competition. No one can question this role of transportation. There is, however, a back-side to the coin: the environmental challenge. READ MORE
