Infrastructure for measuring the current characteristics of railway infrastructure and rolling stock is prerequisite for assessing the condition of the railway. Assessment of the current and estimated condition of the railway contributes to improved risk-based prioritisation of maintenance and traffic management measures to maintain punctuality on the railway.
This report discusses an overall action plan to establish a number of test measurement sites and then connect them to 'Measurement Station Sweden'. Measurement Station Sweden is a platform designed and tested within ePilot, designed for transparent and reproducible tests of scientific theories, calculation tools and new technologies.
The goal of 'Measurement Station Sweden' is to strengthen the adaptability and competitiveness of the railway industry by developing and providing a test bed for research and innovation in the rail industry, both nationally and internationally.
Measurement Station Sweden, called the 'Digital site', aims at a series of interconnected and coordinated measuring sites, called 'Cyberphysical site', for measuring railway systems. A measuring location can be a physical location at or adjacent to the railway network, mobile measuring point or a virtual measuring location. These may in turn be equipped with one or more measurement techniques (such as force measurement, geometry measurement, acoustic measurement). Furthermore, a measuring device can consist of one or more sensors.
The next step is to develop the conditions for upgrading the North Measurement Site together with the stakeholders in ePilot. For the establishment of Measurement Station Sweden, the information logistics that have already been built up, must expand in order to include several measurement sites. Furthermore, the railway network needs to be transparent with regard to the additions of measurement technology that may be needed to obtain a basis for future expansion in order to carry out complete analyses. An industry-wide standard for identifying all system components must be completed in order to ensure traceability and trending capabilities. It is also important to develop a plan to train and prepare the stakeholders for increased digitalisation of maintenance.
Stakeholders: Luleå tekniska universitet, Trafikverket, SJ, Norrtåg, LKAB och Omicold.
