The website introduces the Project SUPERTRACK
(Sustained Performance of Railway Tracks) funded by the European
Commission's 5th Framework Program GROWTH. The research was
motivated by the need for ensuring a better performance of high
speed railway lines. The project was run by nine partners from
France, Spain, Sweden and Norway in the period mid-2002 to mid-2005.
The partners come with geotechnical and railway expertise from R&D
institutes, universities, consulting engineers and mainline railway
administrators. This wide spectrum of background provided the
expertise and experience required to address the various aspects of
the mechanical behaviour of high speed railway lines.The
main objective of the project are to enhance the performance of
ballasted tracks, hence reduction of maintenance, by better
understanding the geotechnical behaviour of the elements of the
embankment and subgrade as well as the dynamic behaviour of the
complete embankment-ground-train system. Although the main emphasis
is on high-speed lines, the findings of the project are equally
valuable for conventional railway lines.
