Reducing the Adverse Effects of Wheel Impacts on Special Trackwork Foundations
ABSTRACT
This report deals with damage to special trackwork due to high impact loads and the beneficial effect of increasing
damping in these foundations. Additional damping attenuates the high magnitude and high frequency of impact generated
transient vehicle-track vibrations. This report covers the first phase of means, manners, and options for analyzing and
enhancing the damping at the special trackwork locations, especially the crossing diamond foundations.
