Using Elastic Components to Improve Rail, Tie, and Ballast Life
by Jeff Tuzik Track condition is about more than rails and ties. It includes everything below the rail and ties, too. Track components, ballast, and subgrade are all part of the package; they all affect overall track condition. And, as Brazil’s MRS Logistica’s track renewal programs have shown, improving track …
Better Track Geometry Through Better Ballast Maintenance
Fabian Hansmann, Head of Marketing at Plasser & Theurer, discussed the challenges of maintaining track geometry amidst limited resources. He emphasized balancing speed, performance, and quality in maintenance practices. Proper ballast management is vital, as defects can accelerate deterioration. Effective tamping techniques significantly influence track stability, underscoring the importance of optimal maintenance strategies.
Smart Rocks, Smart Tamper: Investigating the Mechanics of Ballast Tamping
by Jeff Tuzik 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 …
Under-Tie Pads: Resilient Materials Make an Impact
by Jeff Tuzik Areas of track that are subject to high impacts and dynamic loadings, such as turnouts, diamond crossings and other special trackwork, bridges and bridge approaches, high-degree curves, and highway/rail grade crossings are challenging to manage. Maintenance requires attention, resources, and significant ongoing investment. With more than 30,000 …
