Title:

Under-Tie Pads to Improve Track Resiliency in Railroad Transition Zones
Cover of Under-Tie Pads to Improve Track Resiliency in Railroad Transition Zones

Abstract:

Under-tie pads were installed under twenty-nine (29) ties within an existing high-speed passenger bridge approach on the Northeast Corridor in an effort to alleviate reoccurring track geometry problems at this transition. Anticipated benefits of under-tie pads include: (1) a reduction in approach ballast and tie degradation by better distributing the load to the ballast, (2) increased vibration damping, and (3) reduced contact stress between the tie and individual ballast particles. After installation, the approach track geometry and behavior was measured using track geometry cars and non-invasive instrumentation, e.g., video cameras and accelerometers, to assess performance. These field measurements show stable track geometry after about one year of traffic.
