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 …

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 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 …

FRA Initiatives: Dr. Magdy El-Sibaie, Chief of FRA’s Track Research Division

January 3, 2014 | Filed under: Maintenance, Measurement Systems, Track Geometry, Vehicle/Track

By Bob Tuzik • May 26, 2005 The Federal Railroad Administration’s Office of Research and Development is not the best known R&D organization in the industry, but it is one of the most important. It’s work figures prominently in rulemaking and the regulatory process for the industry. That role is …

The Basics of Successful Grinding (Part 2 of 2)

October 18, 2013 | Filed under: Friction Management, Maintenance, Rail Grinding

By Norman Hooper • July 2010 See Part 1. Experience has shown that an efficient and cost-effective rail grinding program requires attention to basic track inspection and maintenance procedures. This includes attention to “hot spots,” such as joints, welds and road crossings. Figure 1 shows a rail joint at the end …

Reducing the Stress State on Canadian Pacific’s Western Corridor

October 13, 2013 | Filed under: Friction Management, Maintenance, Rail Grinding

By Mike Roney • July, 2009  Canadian Pacific has taken a unique approach to reducing the stress state in its western corridor. The approach includes the implementation of distributed power and the implementation of friction management. It also includes examination of their combined effects — something that is relatively new. Looking at …

The Basics of Successful Grinding (Part 1 of 2)

October 13, 2013 | Filed under: Friction Management, Maintenance, Rail Grinding

By Norman Hooper • January 2010 It behooves railways to periodically review tie, fastener and surfacing maintenance practices, particularly as they relate to the planning and quality of rail grinding procedures. The use of technology, enhanced inspections, regular grinding cycles and friction modification can improve rail surface quality. The safety rationale …
