In order to evaluate the safety of loading and reinforcing scheme of railway out-of-gauge freight from the perspective of dynamic transportation process, the SIMPACK simulation model is established to collect the dynamic data during the transportation process, and safety factors are summarized into four indexes: wagon derail coefficient, wagon capsize coefficient, freight slip coefficient and freight capsize coefficient. On this basis, combine with the principle of neural network evaluation, this paper constructs a safety evaluation model of loading and reinforcing of railway out-of-gauge freights with the above-mentioned transportation process safety factors as the input layer and the comprehensive safety degree as the corresponding output layer. The results show that the lateral shift of gravity center for car loaded the gravity center height for car loaded and the longitudinal shift of gravity center for car loaded have the greatest impact on transportation process safety, and the influence degree is 0.52, 0.32, 0.35, respectively. And the classification of out-of-gauge freight and the length of protruding end have less impact. Other factors have relatively little impact.
