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.

Squats & Studs: Emergent Damage Mechanisms on Rail Transit Systems

ATLANTA – Railway Track & Structures, March 2024 Issue. The unforgiving environment of the wheel/rail interface creates many damage mechanisms. These manifest in defects as varied as corrugations, rolling contact fatigue, and gage-corner cracking, to name only a few.

Quantifying Rail Life Extension with Infinite Rail Grinding Pattern Control

RAILWAY TRACK & STRUCTURES, OCTOBER 2023 ISSUE:Preventive rail grinding is a well-established practice for extending rail life. And by optimizing wheel/rail interaction and controlling the development and growth of surface damage like rolling contact fatigue, rail grinding has proven itself to be one of the industry’s best tools for managing one of its most valuable assets.
