The Tools of Remediation: Case Studies on Mitigating Common Concerns at the Wheel/Rail Interface.

September 15, 2022 | Filed under: Friction Management, Maintenance, Noise and Vibration, Wheel/Rail Interaction

by Jeff Tuzik Transit systems around the world, despite their differences, all contend with the same issues to some degree. Issues like vehicle- and ground-borne vibrations, excess noise, and timetable delays often rise in priority as they generate increasing numbers of complaints. These issues are often symptoms that can be …

Examining Autonomous Track Geometry Testing and Instrumented Revenue Vehicle Technology

September 7, 2022 | Filed under: Friction Management, Measurement Systems, Noise and Vibration, Rail Transit, Wheel/Rail Interaction

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 …

“The Complete Field Guide to Modern Derailment Investigation:” An insiders’ look into the definitive work by the industry’s preeminent derailment investigator.

April 27, 2021 | Filed under: Gary Wolf, Wheel/Rail Interaction

by Bob Tuzik, Executive Program Director – Wheel Rail Seminars If there are lessons to be learned from a derailment — and, of course, there are — then Gary Wolf’s The Complete Field Guide to Modern Derailment Investigation is a master class on finding, analyzing, and understanding the marks on …

Running Longer Trains More Productively and Less Destructively

March 12, 2020 | Filed under: Heavy Haul, Vehicle/Track

by David C. Lester Dave Peltz is literally a rocket scientist. Although he is now Chief of Global Technology for GE Transportation’s (now Wabtec’s) Intelligent Control Systems Division in Melbourne, Fla., he spent time with the U.S. Air Force as a satellite communications systems engineer for the Mill Star satellite …

Moving to Performance-Based Automated Track Inspection: The Benefits and Hurdles Ahead

March 1, 2020 | Filed under: Heavy Haul, Measurement Systems

By David C. Lester The mileage of individual Class 1 railroad networks presents a challenge to inspectors and engineers to inspect frequently enough to keep the track in good shape and minimize the frequency of track-related derailments. Traditional inspections done by railbound geometry cars and flexible hi-rail trucks, with the …

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 – Heavy Haul: Condition Monitoring at the Component Level

February 19, 2018 | Filed under: Wheel/Rail Interaction

By Jeff Tuzik   The railroad is a system. The holistic approach is the optimal approach. This is a maxim often repeated at the Wheel Rail Interaction (WRI) conference, and at railroads around the world. It’s a simple concept but it belies great complexity. At WRI 2017, a number of …

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 …

Big Data in Railroad Maintenance Planning: Evolving Science, Evolving Applications

February 27, 2017 | Filed under: Big Data, Maintenance

By Jeff Tuzik The concept of big data is something the railroad industry has been aware of for many years. The Federal Railroad Administration, for example, has been involved in research and development projects involving big data, neural networks and machine learning since as early as 2002. The prevalence and proliferation …
