• 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.
