Tider i spår för underhållsarbeten


The allocation of time for performing engineering works (track possession time) is strongly linked to maintenance and capacity aspects and demands a planning process that links the needs of maintenance companies and train operators for time on the line. The scope and time required for maintenance operations varies greatly depending on the type of maintenance measure being performed, making it less clear-cut than the timetabled requirements of train services.

The purpose of this project is to study how much track possession time is required to perform various types of maintenance measures on rail infrastructure. The categories of measures on which the project focuses are track replacement; rail replacement; switch replacement and overhead line replacement. The short-term aim is to develop relevant documentation regarding the necessary track possession time for the implementation of maintenance measures. The ability to create the necessary space for maintenance operations is dependent on an understanding of the links between parameters such as the time required to perform a given maintenance measure, the quality of maintenance, work environment and timetabling. This can then be used as the basis for joint discussions between clients, train operators and maintenance contractors regarding how a process or business model that is beneficial to all parties might be developed.

Unique knowledge compilation on microplastics from road traffic

Although we know that tyre and road surface wear generates significant emissions of microplastic particles, knowledge about them is very limited. This is the conclusion of a report issued by the Swedish National Road and Transport Research Institute (VTI).


Measures for infrastructure climate adaptation requires prioritisation

The effect of climate change will result in more extreme weather events causing for example increased risk of floods, and landslides, which will result in great costs to society. Therefore, society needs to prepare for the consequences brought on by climate...


Increased interest in train simulators

VTI has developed a train simulator that has become a valued tool in train driver education and research on how simulators can be used to improve railway technology.


Self-driving Buses in Linköping Part of the EU Project SHOW

The benefits of self-driving vehicles for people with disabilities are one of the focus area for a recently launched EU project linked to self-driving buses in Linköping, Sweden.


Young people's travel habits are important for the transition of the transport system

The transport system is facing a number of challenges due to its negative impact in areas such as the climate, equality and fairness. In a recent report, researchers highlight the voices of young people to get their thoughts on the field of transport.


Connected vehicles solve parking problems

Vehicles circulating in the city centre in search of a free parking space is a growing problem. A cloud service that tracks the traffic situation and the availability of free parking spaces could reduce both traffic and congestion.
