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 …
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 …
By Norman Hooper • January, 2008 This article reflects observations made while serving as Chief Engineer of BC Rail, a Class II railway (now owned by Canadian National) during a period in which the railway reduced service failures and broken rail derailments in dark territory by 60% — an improvement …
By Gary P. Wolf • July, 2007 Much has been written and said about the need to optimize the interface between the wheel and rail, but with the growth of heavy axle load traffic, the mandate for optimum performance is greater than ever. Balancing the wheel/rail equation and optimizing interaction can …
By B. McGuire, R. Sarunac, R. B. Wiley and P. Klauser • April, 2007 Part 1 of this article examined ways in which the use of vehicle performance detectors is steadily growing on North American freight and high-speed passenger railways. With the installation of a Wayside Wheel/Rail Load Detector on …
By Edgar Fischmeister, Markus Ossberger, Roman Pongracz and Paul Mittermayr • April, 2007 Measurement is an essential aspect of optimizing wheel/rail interaction on urban transit systems. After extensive research and development work, Wiener Linien, the Vienna (Austria) Urban Transit System, implemented an integrated wheel/rail measurement system that enabled the railway to closely monitor …
By B. McGuire, R. Sarunac, R. B. Wiley and P. Klauser • April, 2007 The use of vehicle performance detectors is steadily growing on North American freight and high-speed passenger railways. With the installation of a Wayside Wheel/Rail Load Detector (WRLD) on the Washington Metropolitan Area Transit Authority (WMATA), the trend …
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 Bob Tuzik, December 1, 2004 As part of its effort to monitor dynamic vehicle/track interaction on the Northeast Corridor, Amtrak commissioned ENSCO, Inc., to develop a Wayside Train/Track Interaction Detection System. The goal was to measure and collect information on vehicle/track forces that would enable Amtrak to determine the causes of …
