  • Maintenance Optimization and The State of Good Repair

    December 16, 2022 | Filed under: Wheel/Rail Interaction

    By Jeff Tuzik The State of Good Repair is a goal, but it’s also a process. It’s achieved through a series of instruments and instrumental decisions that aim to report on the health of a system from the most granular component level, to the broadest holistic overview. This Part 2 …

  • Using Derailment Findings to Identify Derailment Risks

    November 15, 2022 | Filed under: Heavy Haul, Measurement Systems

    Presenters at the 2022 Wheel/Rail Interaction conference looked at heat and track configuration issues as they relate to derailment potential in heavy-grade, high-tonnage territory. They also looked at the role of Operating parameters in derailment potential, and at the findings from 20 years of investigations into derailments. By Bob Tuzik …

  • Understanding the Role of Human Factors in Railway Inspection

    November 14, 2022 | Filed under: Maintenance

    Presenting experts at Wheel/Rail Interaction 2022 made it clear that there’s more to inspection than meets the eye. Education and training can help reduce errors and improve inspection efficiency. By Bob Tuzik “Human Factors” are frequently cited as cause codes in railway incidents and derailments. But while track and mechanical …

  • 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: 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 …
