Lecture
Recent events in the news have brought about much discussion about the technology used for railroad safety. Towards that end, an introduction will be presented covering the technology and design of critical railroad safety systems and their development over the decades will be discussed. The long evolution of railroad design, especially regarding wheels, axles, bearings and brakes will be covered, along with the classic development of methods used to detect, identify and characterize safety issues. This includes necessary auxiliary systems such as non-contact Axle detection. The newer acoustic defect detection systems will be discussed in detail along with introductions to positive train control, and the proposed electronic brake control systems.
Speaker Bio:
Ed Gellender never grew up, and uses a lifetime accumulation of academic and experience credentials to continue playing with a succession of the biggest and best toys you have ever seen. Ed was working on the railroad all the day long, specifically on trackside thermal and acoustic detection of “hotboxes,” with their associated axle counting sensors, for which he holds a US patent. He also has experience with trackside consist monitoring, automatic train control (ATCS), positive train control (PTC) and onboard status monitoring.
Ed has also worked on a wide variety of aviation and shipboard electronic systems including Radios, Radars, aircraft landing systems, and even weather balloons. Recently, Ed was the cognizant engineer for the APX-122 IFF interrogator on the Navy’s new E-2D radar plane, notably flight testing anti-fratricide combat ID (“Mode5”). Ed has also worked on high power electrical distribution networks all around the New York City Metropolitan area with Con Edison, and also on power distribution on the George Washington, Verrazano, and Triborough Bridges, and Midtown Tunnel.
