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 …
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 …
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 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 …
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 …
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 …
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 …
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 …
