1. Predictive Models for Railway Track Geometry Degradation
Sammanfattning : Railways are a vital and effective means of mass transportation and play a vital role in modern transportation and social development. The benefits of the railway compared to other transportation modes are a high capacity, high efficiency and low pollution, and owing to these advantages, railways are nowadays experiencing a higher demand for the transportation of passengers and goods.

2. Ramverk för en drift- och underhållsstrategi ur ett regelstyrt infrastrukturperspektiv
Sammanfattning : Managing the Swedish state railways is a complex task where internal and external factors must be taken into consideration at the same time as demands for efficiency are made by owners, customers and end customers. Banverket (‘The National Swedish Rail Administration') was formed in 1988 by the Swedish State Railways, a public service corporation, being divided into an infrastructure unit, Banverket, and a transport enterprise, SJ (‘the Swedish State Railways').

3. Maintenance performance indicators (MPIs) for railway infrastructure : identification and analysis for improvement
Sammanfattning : With increasing awareness that maintenance not only ensures safety and track performance, but also creates additional value in the business process; many infrastructure managers and owners are treating maintenance as an integral part of the business process. This is also true for the Banverket (Swedish National Rail Administration). LÄS MER
4. Maintenance strategy for a railway infrastructure in a regulated environment
Sammanfattning : The operation and maintenance of railway infrastructure is complex, strictly regulated by government legislation, and must be working in close cooperation with all the stakeholders including customers involved, in order to avoid sub optimization. The business configuration of the Swedish Railway system makes it very difficult to optimize the entire railway operation, as many times its stakeholders have conflicting demands. LÄS MER
5. Life cycle assessment of transport systems and transport infrastructure : Investigating methodological approaches and quantifying impacts at project and network levels
Sammanfattning : Reducing greenhouse gas emissions from the transport sector is a key challenge to reach global climate targets and limit global warming to below 2 ºC. The use of life cycle assessment (LCA) may provide knowledge about the environmental impacts of transport systems so that emission reduction measures can be identified. LÄS MER
