Big Data in Railroad Maintenance Planning: Evolving Science, Evolving Applications

February 27, 2017 | Filed under: Big Data, Maintenance

By Jeff Tuzik The concept of big data is something the railroad industry has been aware of for many years. The Federal Railroad Administration, for example, has been involved in research and development projects involving big data, neural networks and machine learning since as early as 2002. The prevalence and proliferation …

Modelling Success and Predicting Failure at the Wheel/Rail Interface

January 18, 2017 | Filed under: Heavy Haul, Rail Grinding, Rail Maintenance, Track Geometry, Vehicle/Track, Wheel/Rail Interaction

WRI 2016, Heavy Haul Part 2 See Part 1 By Jeff Tuzik   The worst time to explore the complexities of contact mechanics, lubrication, metallurgies, carbody behavior or other aspects of wheel/rail interaction is at a derailment site. But it’s often the most instructive. As George Fowler, Senior Investigator at …

Investigating Wear and Damage Mechanisms

January 17, 2017 | Filed under: Wheel/Rail Interaction

WRI 2016, Heavy Haul Part 1 See Part 2 By Jeff Tuzik The Railroad Industry isn’t known for rapid change. Slow and steady progress has generally characterized the industry approach to new technologies, maintenance strategies and operational practices. That’s beginning to change. Some of the changes the industry is grappling …

Big Data in Railroad Maintenance Planning: 2016

October 15, 2016 | Filed under: Wheel/Rail Interaction

Big Data – it’s more than a buzzword. Big data represents a challenge and an opportunity that every industry is looking into. The railroad industry is no exception. How to manage, harness and exploit big data has become a regular part of railroad conferences around the world. In 2015, Dr. …

ICRI Workshop: A Discussion on RCF Remediation

October 1, 2016 | Filed under: Friction Management, Maintenance, Rail Grinding, Wheel/Rail Interaction

By Jeff Tuzik Rolling Contact Fatigue (RCF) is an issue every railroad, and many transit systems, around the world must contend with. Despite its ubiquity, RCF is not perfectly understood. There are many researchers, railroad operators and suppliers, experts in their field, working to understand and eliminate RCF and its attendant …

WRI 2016 – Transit: Integration, Correlation, Remediation

August 1, 2016 | Filed under: Big Data, Measurement Systems, Rail Transit, Wheel/Rail Interaction

By Jeff Tuzik   It’s easier now than ever to collect data on wheel/rail interaction. The number of measurement tools, the number of parameters that can be measured, and the accuracy of those measurements have changed the way wheel and rail systems are designed, monitored and maintained. While all of …

WRI EU 2015, Part 2: Theory to Practice, Laboratory to Track

June 20, 2016 | Filed under: Rail Grinding, Track Geometry, Vehicle Design, Wheel/Rail Interaction, Wheel/Rail Profile

By Jeff Tuzik See Part 1 A thorough understanding of the forces contributing to wheel/rail interaction requires a grasp of both theoretical concepts and operational practices. Speakers at the 2015 Wheel Rail Interaction Conference, European Union (WRI EU) addressed both, presenting findings from the lab and operating environment of vehicles …

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 …
