by Jeff Tuzik Preventive rail grinding is a well-established practice for extending rail life. And by optimizing wheel/rail interaction and controlling the development and growth of surface damage like rolling contact fatigue, rail grinding has proven itself to be one of the industry’s best tools for managing one of its …
by Bob Tuzik Gary Wolf, president of Wolf Railway Consulting, is the recipient of the 2023 Worth Award. The award, presented by Wheel Rail Seminars at the annual Wheel/Rail Interaction conference in June, is named for Art Worth, who was Manager of Standards and retired as Senior Manager – Advanced …
by Jeff Tuzik Areas of track that are subject to high impacts and dynamic loadings, such as turnouts, diamond crossings and other special trackwork, bridges and bridge approaches, high-degree curves, and highway/rail grade crossings are challenging to manage. Maintenance requires attention, resources, and significant ongoing investment. With more than 30,000 …
by Jeff Tuzik Among the most significant forces that freight railroads contend with in daily operations are buff and draft (or compressive and tensile) forces between cars within train consists. These forces are mediated by various damping technologies, braking and acceleration practices, and by train make-up. When these forces aren’t …
New all-season TOR and GF FM products show performance and efficiency benefits over traditional seasonal variants.
by Jeff Tuzik Seattle’s Link Light Rail, operated by Sound Transit, is a fairly young system. And by most standards, a small system. But it’s also a sophisticated system, and it’s growing fast. The system currently operates 25 miles of track and is in the midst of expanding to 50 …
By Jeff Tuzik On freight railroads, rail is generally the largest single asset, capital expenditure, and one of the primary costs. From a maintenance perspective, rail is subject to wear and defect development, both of which can be actively managed in a number of ways. From an accounting perspective, rail …
By Jeff Tuzik Railroads around the world have many standards for wheel and rail hardness, with varied combinations of interacting harder and softer materials. And while it is intuitively apparent that harder materials should wear less, last longer and generally provide a net benefit to a system, the details and …
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 …
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 …
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 …
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 …
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 …
