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 …
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 …
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 …
WRI 2016, Heavy Haul Part 2 See Part 1 By Jeff Tuzik The worst time to explore the complexities of contact mechanics, lubrication, metallurgies, carbody behavior or other aspects of wheel/rail interaction is at a derailment site. But it’s often the most instructive. As George Fowler, Senior Investigator at …
