Performance Indicators of Railway Infrastructure
International Journal of Railway Technology, 2012 Railway traffic has increased over the last decade and it is believed to increase further with the movement of transportation from road to rail, due to the increasing energy costs and demand to reduce emissions. As a result of increasing need of railway capacity, more efficient and effective operation and maintenance is required.

Change Detection: The Framework of Visual Inspection System for Railway Plug Defects
IEEE Access, 2020 Railway plug defects impact the safety of a railway system. To detect railway plug defects, we establish the framework of a visual inspection system (VIS), which is the first system that can perform railway plug inspection automatically and intelligently.

MAINTENANCE LAYERS FOR RAILWAY INFRASTRUCTURE IN POLAND
Transport, 2021 The railway network in Poland with over 19000 km is one of the biggest in the European Union (EU). At the same time safety indicators collected by the European Union Agency for Railways (ERA) show that it is one of the least safe in Europe. Consequently, all the actions taken in safety management of Polish Railways are particularly important for the ...
