The model developed to simulate the head-on collision of two lead locomotives, each in a multi-locomotive, multi-trailing-vehicle train, appears to provide a good simulation of the resulting extent of override and crush in the lead locomotives. Results of this study show that trailing vehicles (nonlocomotives) and the effects of derailment need not be modeled to predict the crush response of the lead locomotives. Comparison of the model predictions to observations for three accidents described in FRA reports are all in good agreement. Although the model has been validated for closing speeds up to 43 mph, we believe that it can provide useful results on lead locomotive crush response for higher speeds.
