Friction Management

Meeting the Industry’s Technology Goals

January 4, 2014 | Filed under: Friction Management, Measurement Systems, Wheel/Rail Interaction

by Bob Tuzik, January, 2008 The wheel/rail interface must be managed in order to increase the life of rail and rolling stock components and to reduce in-service failures. This was one of the primary messages delivered at the Association of American Railroads/Transportation Technology Center, Inc.’s 14th Annual Research Review. The research …

Wheel/Rail Interaction ’08: Data to Information (Part 2 of 2)

January 4, 2014 | Filed under: Friction Management, Measurement Systems, Rail Grinding, Wheel Maintenance, Wheel/Rail Interaction

By Jeff Tuzik • October, 2008 Part 1 of this article examined efforts to optimize vehicle and track component performance through various testing, monitoring and simulation programs. Part 2 continues on the theme of “data to information,” further exploring such programs and the operational benefits they engender. Maintaining a Safe Neutral Temperature (SFT) on …

Controlling Friction on Rail Transit Systems

January 3, 2014 | Filed under: Friction Management, Rail Transit

By Bob Tuzik • January, 2007 Friction control plays a major role in reducing wear, noise and vibration, and managing wheel/rail interaction on rail transit systems. Controlling friction has become more achievable with the advent of engineered friction modifiers and improvements to wayside and onboard application systems for both traditional lubricants …

Reducing Noise and Vibration on NYCT

January 3, 2014 | Filed under: Friction Management, Noise and Vibration, Rail Transit, Vehicle Design, Vehicle/Track

by Bob Tuzik, January 1, 2005 Any problem affecting the New York City Transit is by default a big problem. The process of transporting more than four million passengers per day in 6,000 vehicles on more than 700 miles of elevated, underground at-grade mainline tracks, on a system that operates 24 hours …

Drilling Down to Top-of-Rail Friction Control

January 3, 2014 | Filed under: Friction Management, Rail Transit

by Bob Tuzik February 1, 2005 There are two primary approaches to friction management on rail transit systems: onboard and wayside. The most effective method depends upon the demands of the system. A relatively small system with consistent degrees of curvature, for example, might lend itself to onboard application. A system with …

Examining wheel/rail interaction on rail transit systems

January 3, 2014 | Filed under: Friction Management, 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 …

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 …

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 …
