Wheel/rail noise measurements were performed to assess the effectiveness of wheel and rail vibration absorbers for reducing wayside noise. The project included procurement and installation of wheel vibration absorbers on Bochum 84 and 54 resilient wheels for testing at the systems of New Jersey Transit (NJT) and Tri-County Metropolitan Transportation District of Oregon (Portland Tri-Met), respectively, at both tangent and curved track. Rail vibration absorbers were also procured and installed at the Portland Tri-Met and tested at both tangent and curved track. The measurements included wayside noise, under-car noise, and rail vibration.
