Examining wheel/rail interaction on rail transit systems

January 3, 2014 | Filed under: Friction Management, Gary Wolf, Noise and Vibration, Rail Grinding, Rail Transit, Wheel Maintenance, Wheel/Rail Interaction

By Bob Tuzik • November 4, 2004 If the first unwritten rule in optimizing the wheel/rail interface on rail transit is: Know your system; the second rule should be: Recognize that the w/r interface is a system. “No single department can attack the issues in isolation and expect to get very far,” Joseph Oriolo, Senior …

Inspection and Analysis of Switch Derailments (Part 2 of 2)

January 2, 2014 | Filed under: Gary Wolf, Rail Maintenance, Vehicle/Track, Wheel Maintenance

By Gary Wolf Part 1 of this article examined trailing-point derailments, facing-point derailments and thin flange wheels. Part 2 examines wheel climb and frog-related derailments. Crosslevel variances in turnout geometry represent a common cause of wheel-climb derailments. It’s not unusual to find bolted or insulated joints within 30 to 40 …

Switch Point Derailments: Is it the point or the wheel? (Part 1 of 2)

January 2, 2014 | Filed under: Gary Wolf, Rail Maintenance, Wheel Maintenance

By Gary Wolf No other type of derailment causes as much angst among railroaders as the switch point derailment. The switch point derailment can take several forms, but it generally boils down to a disagreement between the Mechanical Department that blames the switch point, and the Engineering Department that blames …

Management of the Wheel/Rail Contact Interface in Heavy-Haul Operations (Part 1 of 2)

October 18, 2013 | Filed under: Friction Management, Heavy Haul, Rail Grinding, Wheel Maintenance, Wheel/Rail Interaction

By Huimin Wu and Semih Kalay • October, 2009 Wear and rolling contact fatigue (RCF) of rails and wheels are common problems under heavy-haul operations. Increasing axle loads can increase the capacity of a railway system, but also can increase the stress state of the system. A root cause of RCF …

Management of the Wheel/Rail Contact Interface in Heavy-Haul Operations (Part 2 of 2)

October 18, 2013 | Filed under: Friction Management, Heavy Haul, Rail Grinding, Wheel Maintenance, Wheel/Rail Interaction

By Huimin Wu and Semih Kalay • January 2010 See Part 1 of this article here. What are the differences between rail shapes that produce higher contact conicities and those that produce lower contact conicities? The profiles shown in Figures 1a and 1b illustrate the differences that can result in significant …
