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 …
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 …
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 …
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 …
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 …
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 …
