A pair of speakers from different continents discuss the benefits of autonomous track geometry collection and the advantages of monitoring revenue-service vehicles’ response to track conditions in this first installment of topics covered at this year’s annual Wheel/Rail Interaction Conference in Vancouver, B.C., Canada. By Bob Tuzik Brad Kerchof wasted …

A First Look at Rail Milling in North America

February 27, 2020 | Filed under: Rail Maintenance, Rail Transit

By Richard Stock Rail Milling technology, which was introduced by Linsinger about 25 years ago, has been widely used in Europe, Asia, and Australia. It was recently introduced in North America. Unlike other maintenance technologies, rail milling is a non-abrasive cutting process where material is cut from the rail surface …

Rail Transit 2018: Quantifying Wheel/Rail Interaction and Managing Noise and Vibration

October 23, 2018 | Filed under: Noise and Vibration, Rail Transit, Wheel/Rail Interaction, Wheel/Rail Profile

By Bob Tuzik For three years running, New York City Transit and the Federal Transit Administration have kicked off the annual Wheel/Rail Interaction – Rail Transit conference with discussion of the NYCT/FTA research project to explore integrated wheel/rail analytics on MTA-NYCT’s No. 7 Flushing Line. It’s a fitting start to …

WRI 2017 – Transit: System Optimization and Better Asset Management

July 3, 2017 | Filed under: Rail Transit, Vehicle Design, Vehicle/Track, Wheel/Rail Interaction, Wheel/Rail Profile

By Jeff Tuzik Optimization, modernization and asset management are critical to the efficient running of a rail transit system. While each program is beneficial in its own right, the importance of asset management has taken on new significance with the recent Federal Transit Administration’s (FTA) rule making on the State …

WRI 2016 – Transit: Integration, Correlation, Remediation

August 1, 2016 | Filed under: Big Data, Measurement Systems, Rail Transit, Wheel/Rail Interaction

By Jeff Tuzik   It’s easier now than ever to collect data on wheel/rail interaction. The number of measurement tools, the number of parameters that can be measured, and the accuracy of those measurements have changed the way wheel and rail systems are designed, monitored and maintained. While all of …

WRI EU 2015 Part 1: Systemic Challenges, Systemic Successes

April 12, 2016 | Filed under: Friction Management, Maintenance, Rail Grinding, Rail Maintenance, Rail Transit, Wheel/Rail Interaction, Wheel/Rail Profile

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 …

WRI 2015: Transit — Maintenance and the State of Good Repair

July 8, 2015 | Filed under: Friction Management, Rail Grinding, Rail Maintenance, Rail Transit, Wheel/Rail Interaction

By Jeff Tuzik Maintaining a state of good repair (SGR) weighed heavily on the minds of those in attendance at the 2015 Rail Transit Wheel Rail Interaction Conference, as transit properties will be required to meet requirements established by the Federal Transit Administration as early as next year. SGR – …

by Jeff Tuzik   The 20th annual Wheel/Rail Interaction Conference drew a record number of attendees and speakers from around the world. They came to contribute to and draw from the growing body of knowledge on wheel/rail interaction. Since the conference began 20 years ago, the industry has come a …

Using High-Performance Mass-Spring Systems to Reduce Noise and Vibration in Track

January 4, 2014 | Filed under: Noise and Vibration, Rail Transit, Vehicle/Track

By Hans-Georg Wagner • July, 2008 The transmission of noise and vibration associated with the close proximity of rail lines to houses and office buildings has become a significant issue in metropolitan areas. The operators of rail transit systems have begun turning to measures that mitigate noise and vibration and the …

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 …
