1. Railway Infrastructure Robustness : Attributes, evaluation, assurance and improvement
Abstract : According to the European program Horizon 2020, multifaceted challenges in transportinfrastructure include 1) making infrastructure more resilient to keep pace with the increasing mobility needs; 2) reducing the impact of infrastructure on the environment;and 3) dealing with declining resources to maintain and upgrade transport infrastructure. New design and maintenance approaches must be developed to handle these issues, ascurrent methods are inadequate. READ MORE

2. Railway operation analysis : Evaluation of quality, infrastructure and timetable on single and double-track lines with analytical models and simulation
Abstract : This thesis shows the advantages of simple models for analysis of railway operation. It presents two tools for infrastructure and timetable planning. It shows how the infrastructure can be analysed through fictive line designs, how the timetable can be treated as a variable and how delays can be used as performance measures. READ MORE

3. Data-driven models for railway track geometry maintenance
Abstract : Railways are currently experiencing higher demands on safety, infrastructure performance, network capacity and service quality, etc. As a result, a high level of track availability, service quality and infrastructure robustness against unexpected events is required, at reduced cost, to meet the demands.

5. The Railway Station and The Interregional Traveller - traveller preferences and implications for the planning process
Abstract : The interregional traveller’s preferences of railway stations, their service provision and location, are of interest in the discussion of station reinvention brought on by the introduction of high speed train traffic. A railway station is created by station as well as societal agents, and can be described as a synthesis of symbolic value, location, traffic, services and stationscape. READ MORE
