Thermal buckling of railroad tracks in the lateral plane is an important problem in the design and maintenance of continuous welded rail (CWR) tracks. The severity of the problem is manifested through the large number of derailments which are attributable to track buckling, indicating a need for developing better control on the allowable safe temperature increase for CWR tracks. This report presents the results of a series of track dynamic buckling tests investigating the influences of vehicle induced loads on the thermal buckling behavior of tangent and curved tracks. Comparisons between theoretical predictions and experimental results are given, and conclusions of practical significance regarding the buckling safety of CWR tracks under dynamic conditions are presented.
