Taking the Long View: 20 Years of Wheel/Rail Interaction (Part 2 of 2)

April 22, 2014 | Filed under: Friction Management, Gary Wolf, Heavy Haul, Measurement Systems, Rail Maintenance, Track Geometry, Vehicle/Track, Wheel/Rail Interaction

Part 2. Friction Management, Vehicle Suspension and Measurement Systems By Bob Tuzik, April 2014 Part 1 of this article explored advances in metallurgy, wheel/rail profile design and maintenance practices. Part 2 continues the theme, examining the technologies and techniques that have shaped our understanding of wheel/rail interaction. While the practice of …

Taking the Long View: 20 Years of Wheel/Rail Interaction (Part 1 of 2)

January 8, 2014 | Filed under: Gary Wolf, Rail Grinding, Track Geometry, Wheel/Rail Interaction, Wheel/Rail Profile

Part 1. Metallurgy, Wheel/Rail Profile Design and Maintenance. by Bob Tuzik, January 2014 Ask a group of railroaders, researchers or suppliers what the essential aspects of understanding wheel/rail interaction have been over the past 20 years, and you’ll get a host of answers. But among them, major categories consistently emerge: …

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 1 of 2)

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

By Bob Tuzik • July, 2008 As research into wheel/rail interaction has evolved, the emphasis has moved toward implementation of available technology and conversion of data into information. Such was the case at Wheel/Rail Interaction ’08, the 14th annual seminar produced by Advanced Rail Management and sponsored by Progressive Railroading magazine. Railroaders, researchers …

Implementing Wheel/Rail Measurement and Analysis Technology

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

By Bob Tuzik • July, 2008 Any examination of the systems in use to measure and monitor wheel/rail interaction requires a discussion of the challenges associated with implementing new and emerging technology. Several industry practitioners participated in such a discussion at Advanced Rail Management and Progressive Railroading magazine’s Wheel/Rail Interaction ’08, the 14th …

Managing Wheel/Rail Interaction on Rail Transit Systems

January 4, 2014 | Filed under: Rail Grinding, Rail Transit, Vehicle/Track, Wheel Maintenance, Wheel/Rail Interaction

By Bob Tuzik • January, 2008 All railways must deal with operating/engineering and vehicle/track interaction issues. But rail transit systems, which operate under the microscope of the urban environment, face special, often unique, challenges. Speakers at Rail Transit ’07, Advanced Rail Management and Interface Journal’s third seminar devoted to wheel/rail interaction on rail …

Tuning in to the Systems Approach

January 4, 2014 | Filed under: Vehicle/Track, Wheel/Rail Interaction

By Bob Tuzik • July, 2007 You’ve heard it before, you’ll hear it again. Delegates to the 13th Annual Wheel/Rail Interaction Seminar presented by Interface Journaland Advanced Rail Management heard it time and again over the course of the seminar: The wheel/rail interface is a system. And when there are problems, as …

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 …

The What, Where, Why and How of Rail Grinding

January 3, 2014 | Filed under: Rail Grinding

The Art and Science of Rail Grinding, by Allan M. Zarembski Book review by Bob Tuzik • March, 2006 If you’re like me, your filing cabinet is stuffed with articles from various publications. If you’re organized, you may have a specific folder or binder with articles on rail grinding clipped …
