Purpose: To create an information basis for the modernization of existing and development of new methods for optimal railway routing in areas with difficult rough terrain. Methods: Mathematical modelling, optimisation methods, and decision theory were applied. Results: A computational experiment was conducted, its stages were determined, and an algorithm was developed for forming a set of acceptable route variants on a terrain section with a longitudinal watershed, two transverse watersheds and a ravine. Practical significance: A thorough examination of the experiment’s outcomes reveals that the numerous viable railway route alternatives in regions with complex, rough terrain will provide a substantial information foundation for enhancing the mathematical support for the implementation of innovative technology in computer-aided railway designs. This should result in a significant reduction in the time required to make effective design decisions.
