WRI EU 2015 Part 1: Systemic Challenges, Systemic Successes

April 12, 2016 | Filed under: Friction Management, Maintenance, Rail Grinding, Rail Maintenance, Rail Transit, Wheel/Rail Interaction, Wheel/Rail Profile

By Jeff Tuzik For over 20 years, the Wheel/Rail Interaction conferences have brought together railway industry professionals, researchers and suppliers to share their expertise in the field of wheel/rail interaction. Until recently, the conferences have been held only in the United States and have drawn on North American experiences. In …

WRI 2015 — Heavy Haul Part 2: A Proactive Approach to Asset Management

December 5, 2015 | Filed under: Friction Management, Heavy Haul, Maintenance, Measurement Systems, Vehicle/Track, Wheel/Rail Interaction, Wheel/Rail Profile

By Jeff Tuzik (See Part 1) The benefits of taking a proactive approach to wheel/rail interface management are well known. Year after year at Wheel Rail Interaction conferences, speakers have extolled the benefits of moving away from costly reactive maintenance strategies. The “firefighting” method of moving from one critical exception to …

WRI 2015 — Heavy Haul Part 1: Interface Management From Micro to Macro

September 1, 2015 | Filed under: Big Data, Friction Management, Heavy Haul, Rail Cant, Rail Grinding, Wheel/Rail Interaction

 By Jeff Tuzik (Continue to Part 2) Proper management of the wheel/rail interface is a daunting process. It involves elements of design and planning, automated and manned inspection, corrective and preventive maintenance and data management, to name only a few. Managing the systemic health of a railroad means understanding processes that range from the …

WRI 2015: Transit — Maintenance and the State of Good Repair

July 8, 2015 | Filed under: Friction Management, Rail Grinding, Rail Maintenance, Rail Transit, Wheel/Rail Interaction

By Jeff Tuzik Maintaining a state of good repair (SGR) weighed heavily on the minds of those in attendance at the 2015 Rail Transit Wheel Rail Interaction Conference, as transit properties will be required to meet requirements established by the Federal Transit Administration as early as next year. SGR – …

Vehicle, Track and Wheel: Safety and Efficiency at the Wheel/Rail Interface

April 9, 2015 | Filed under: Wheel/Rail Interaction

WRI 2014 Heavy Haul: Part 2 (See Part 1) by Jeff Tuzik Wheel/rail interaction impacts virtually every aspect of railroading, including operational safety and efficiency, the effectiveness of vehicle and track maintenance and maintenance planning. WRI affects the bottom line, too. When things go wrong, the culprit is often somewhere …

Automated Inspection and the Power of Data: A Panel Discussion from WRI 2014

January 27, 2015 | Filed under: Heavy Haul, Measurement Systems

by Jeff Tuzik It wasn’t so long ago that measurement technology referred to calipers, gauges, or other tools. And it wasn’t so long ago that the data railroads collected on their properties was measured in pages instead of gigabytes. Now, the data flows constantly. Automated measurement technologies, both vehicle- and …

Big Challenges, Big Opportunities: Big Data

January 7, 2015 | Filed under: Wheel/Rail Interaction

by Jeff Tuzik   Raw data by itself doesn’t always help much. In fact, it can be a burden. Extracting actionable information from raw data is an issue that the railroad industry has grappled with for years. (See WRI 2008: Data to Information) And as measurement and monitoring technologies have advanced, …

Data to Decisions: Tools and Technology to Manage Wheel/Rail Interaction

September 15, 2014 | Filed under: Heavy Haul, Measurement Systems

WRI 2014 Heavy Haul: Part 1 by Jeff Tuzik   A lot has changed since the early days of wheel/rail interface management. New technologies present new opportunities and challenges, while legacy systems are continually honed and adapted to new practices. Automated inspection technologies and data management are only the latest …

WRI 2014 Transit: A Systems Approach to Wheel/Rail Interaction

June 29, 2014 | Filed under: Friction Management, Measurement Systems, Noise and Vibration, Rail Grinding, Rail Transit, Vehicle/Track, Wheel/Rail Interaction

by Jeff Tuzik   The 20th annual Wheel/Rail Interaction Conference drew a record number of attendees and speakers from around the world. They came to contribute to and draw from the growing body of knowledge on wheel/rail interaction. Since the conference began 20 years ago, the industry has come a …

Measuring With Eddy Current: Gauge Corner Cracking and the Magic Wear Rate

May 25, 2014 | Filed under: Measurement Systems, Rail Maintenance, Wheel/Rail Interaction

By Ryan McWilliams and Eric Eberius Gauge corner cracking (GCC) of the rail from rolling contact fatigue (RCF) is a dangerous and costly form of rail damage. Unfortunately, it’s also notoriously difficult to measure. And as GCC becomes more prevalent on rail systems around the world, accurate measurement is an …
