Wheel/Rail Interaction

Quantifying Rail Life Extension with Infinite Rail Grinding Pattern Control

September 7, 2023 | Filed under: Wheel/Rail Interaction

by Jeff Tuzik 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 …

Under-Tie Pads: Resilient Materials Make an Impact

September 2, 2023 | Filed under: Heavy Haul, Wheel/Rail Interaction

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 …

Managing Slack in Trains with Cars Equipped with Hydraulic End-of-Car-Cushioning Devices

July 24, 2023 | Filed under: Wheel/Rail Interaction

by Jeff Tuzik Among the most significant forces that freight railroads contend with in daily operations are buff and draft (or compressive and tensile) forces between cars within train consists. These forces are mediated by various damping technologies, braking and acceleration practices, and by train make-up. When these forces aren’t …

Sound Transit Studies Wheel/Rail Interaction Differences Between Vehicle Types

April 23, 2023 | Filed under: Rail Transit, Vehicle/Track, Wheel Maintenance, Wheel/Rail Interaction

by Jeff Tuzik Seattle’s Link Light Rail, operated by Sound Transit, is a fairly young system. And by most standards, a small system. But it’s also a sophisticated system, and it’s growing fast. The system currently operates 25 miles of track and is in the midst of expanding to 50 …

Steel Hardness and Wear at the Wheel/Rail Interface: Perception vs Reality

February 6, 2023 | Filed under: Heavy Haul, Rail Maintenance, Wheel/Rail Interaction

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 …

Maintenance Optimization and The State of Good Repair

December 16, 2022 | Filed under: Wheel/Rail Interaction

By Jeff Tuzik The State of Good Repair is a goal, but it’s also a process. It’s achieved through a series of instruments and instrumental decisions that aim to report on the health of a system from the most granular component level, to the broadest holistic overview. This Part 2 …

The Tools of Remediation: Case Studies on Mitigating Common Concerns at the Wheel/Rail Interface.

September 15, 2022 | Filed under: Friction Management, Maintenance, Noise and Vibration, Wheel/Rail Interaction

by Jeff Tuzik Transit systems around the world, despite their differences, all contend with the same issues to some degree. Issues like vehicle- and ground-borne vibrations, excess noise, and timetable delays often rise in priority as they generate increasing numbers of complaints. These issues are often symptoms that can be …

Examining Autonomous Track Geometry Testing and Instrumented Revenue Vehicle Technology

September 7, 2022 | Filed under: Friction Management, Measurement Systems, Noise and Vibration, Rail Transit, Wheel/Rail Interaction

A pair of speakers from different continents discuss the benefits of autonomous track geometry collection and the advantages of monitoring revenue-service vehicles’ response to track conditions in this first installment of topics covered at this year’s annual Wheel/Rail Interaction Conference in Vancouver, B.C., Canada. By Bob Tuzik Brad Kerchof wasted …

“The Complete Field Guide to Modern Derailment Investigation:” An insiders’ look into the definitive work by the industry’s preeminent derailment investigator.

April 27, 2021 | Filed under: Gary Wolf, Wheel/Rail Interaction

by Bob Tuzik, Executive Program Director – Wheel Rail Seminars If there are lessons to be learned from a derailment — and, of course, there are — then Gary Wolf’s The Complete Field Guide to Modern Derailment Investigation is a master class on finding, analyzing, and understanding the marks on …
