This report is a part of the John A. Volpe National Transportation Systems Center's Track Stability Research Program for the Federal Railroad Administration on thermal buckling of continuous welded rail (CWR) track and its prevention. Presented in this report are the developments of theoretical results and the development and application of the CWR-SAFE computer software model for prediction of CWR track buckling strength. This comprehensive predictive model encompasses several different modules designed to perform both deterministic and probabilistic buckling analyses, based on the dynamic buckling theory previously validated by tests, and predicts safe limits for buckling prevention. The model accounts for all the important parameters influencing track buckling, such as rail size, curvature, lateral resistance, tie- ballast friction, fastener torsional and longitudinal resistances, track vertical stiffness, misalignment amplitude and wavelength, and vehicle parameters. Applications of the model are demonstrated through analyses of parametric sensitivity, development of buckling safety limits in terms of safe and critical temperatures, and evaluation of annual probability of buckling occurrences for typical CWR line segments. The report also presents techniques to determine the input parameters for CWR-SAFE application and a practical methodology for CWR track safety monitoring. A risk-based approach is proposed to provide more flexibility to the industry in achieving a minimum number of annual buckles in a given territory and to provide science-based guidelines for improved slow order policies when operating at elevated rail temperatures.

Gripping forensic tales explain how and why trains crash. Trains are massive—with some weighing 15,000 tons or more. When these metal monsters collide or go off the rails, their destructive power becomes clear. In this book, George Bibel presents riveting tales of trains gone wrong, the detective work of finding out why, and the safety improvements that were born of tragedy. Train Wreck details numerous crashes, including 17 in which more than 200 people were killed. Readers follow investigators as they sift through the rubble and work with computerized event recorders to figure out what happened. Using a mix of eyewitness accounts and scientific explanations, Bibel draws us into a world of forensics and human drama. Train Wreck is a fascinating exploration of • runaway trains • bearing failures • metal fatigue • crash testing • collision dynamics • bad rails
