Abstract	The purpose of the work is to validate the safety assessment methodology previously developed for passenger rail vehicle dynamics, which requires the application of simulation tools as well as testing of vehicles under different track scenarios. This report specifically addresses the evaluation of the tasks in the methodology related to measurement of vehicle and track parameters, test conduct, and correlation of the test results with computer simulation results. This report presents a summary of the testing and correlation with OMNISIM computer simulation results for two different rail passenger rail car designs. The first design had non-equalized trucks and the second had equalized trucks. The tests and OMNISIM simulation correlations included vehicle response to variations in vertical alignment, steady curving, dynamic curving, yaw and sway, twist and roll, pitch and bounce, and hunting with initial alignment defects.
