Rail grinding and milling are essential rail maintenance practices, with grinding being more established and milling gaining popularity, especially in Europe. While both processes can achieve similar rail profiles, they differ in technique, productivity, and byproducts. Grinding produces heat and sparks, while milling offers a cleaner operation. Understanding these differences is crucial for optimal rail maintenance strategies.
By Jeff Tuzik 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. Among the most vexing defects that commuter, transit and high-speed rail lines contend with are squat-type defects …
By Jeff Tuzik Railroads around the world have many standards for wheel and rail hardness, with varied theories regarding the interaction of harder and softer steels. And while it is intuitively apparent that harder materials should wear less, last longer and generally provide a net benefit to systemic resilience, the …
