How Rail Grinding and Milling Affect Noise on Transit Systems

by Jeff Tuzik A well optimized wheel/rail interface is a quiet wheel/rail interface. In the rail transit environment, there are many technologies and strategies to reduce wheel/rail-generated noise, and they tend to focus on reducing rail roughness. Standard rail grinding, acoustic rail grinding, rail milling, and specialized acoustic grinding machines …

Rail Grinding and Milling: How They Work, Where They Work

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.
