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 …
WRI 2016, Heavy Haul Part 1 See Part 2 By Jeff Tuzik The Railroad Industry isn’t known for rapid change. Slow and steady progress has generally characterized the industry approach to new technologies, maintenance strategies and operational practices. That’s beginning to change. Some of the changes the industry is grappling …
By Jeff Tuzik Rolling Contact Fatigue (RCF) is an issue every railroad, and many transit systems, around the world must contend with. Despite its ubiquity, RCF is not perfectly understood. There are many researchers, railroad operators and suppliers, experts in their field, working to understand and eliminate RCF and its attendant …
by Jeff Tuzik Raw data by itself doesn’t always help much. In fact, it can be a burden. Extracting actionable information from raw data is an issue that the railroad industry has grappled with for years. (See WRI 2008: Data to Information) And as measurement and monitoring technologies have advanced, …
