1. On Derailment-Worthiness in Rail Vehicle Design : Analysis of vehicle features influencing derailment processes and consequences
Abstract : This thesis aims at systematically studying the possibilities of minimizing devastating consequences of high-speed rail vehicle derailments by appropriate measures and features in the train design including the running gear. Firstly, an empirical database is established containing as much relevant information as possible of past incidents and accidents that have occurred at substantial running speeds due to mechanical failure close to the interface between the running gear and the track.

2. 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.

3. A study of the rail degradation process to predict rail breaks
Abstract : Rail infrastructure is a large and costly investment, and has a long life. To realize the benefits from this investment, effective maintenance is required. READ MORE

4. Condition-based maintenance for effective and efficient rolling stock capacity assurance : A study on heavy haul transport in Sweden
Abstract : All businesses need equipment to deliver services or manufacture goods. Over time, this equipment will degrade, but with proper maintenance, the degradation can be controlled, and failed equipment can be restored to operational status. Run-to-failure maintenance is performed when equipment or systems break down. READ MORE

5. Towards adaptive bogie design
Abstract : Suspension components play a crucial role in bogie dynamics behavior. In this regard, passive and active systems are developed to meet various design requirements. Adaptive suspension systems can adjust the bogie dynamics with respect to different operational scenarios and as a result improve the vehicle performance. READ MORE
