Goals. To analyze the comparison of methods for calculating the load capacity of metal span structures. Research methods. Metal span structures designed for loads at the beginning of the 20th century was used as a calculation model. The results of the study. Analysis of the comparison of the assessment of the load capacity of metal bridge spans according to regulatory documents and with the help of modern software. Calculations using the example of a single span structure, it is shown that, despite the proximity of the results, some elements are estimated by the calculated method with a significant revaluation. Conclusions. The analysis revealed that the importance of an accurate assessment of the load-lifting capacity is associated with the accuracy of the assessment of the probability of failure and, consequently, with the safety of train traffic.
