Track Structure

Smart Rocks, Smart Tamper: Investigating the Mechanics of Ballast Tamping

ATLANTA – Railway Track & Structures, April 2024 Issue: There are many forces that work to deteriorate track geometry over time. These forces don’t begin and end at the wheel/rail interface; they are transmitted to the vehicles and their components and into the track structure and its components. On ballasted track, ballast absorbs these forces, and its maintenance is critical to preserving and correcting several types of track geometry defects.
