Abstract:Under a contract with the Federal Railroad
Administration (FRA), the University of Illinois at Urbana
Champaign (UIUC) is investigating different factors that
contribute to the problem of differential movement at
railroad track transitions The research objective is to
develop new design and rehabilitation methods to
mitigate the problem of differential movement at track
transitions. In order to achieve this goal, UIUC
researchers are using geotechnical instrumentation and
performance monitoring equipment to quantify the
contributions of different substructure layers to
differential movement at railroad bridge approaches. As
part of the study, UIUC instrumented two undergrade
bridge approaches on Norfolk Southern Railway’s (NS)
N-Line mainline near Ingleside, WV, to investigate the
frequent deterioration in track geometry at these sites.
This report provides a brief overview of the
instrumentation activity, the data acquisition approach,
and preliminary results.
