For many companies and logistics centres, rail transport is a key aspect and an essential part of their business. End customers expect their goods to be transported by carriers in a fast, reliable, and efficient manner. However, in many cases, the efficiency and resilience of rail transportation is affected by emergencies such as natural disasters, accidents, and track maintenance. In such cases, situations can arise that make it difficult for carriers to meet their customers' expectations and can even significantly impact the entire transportation process. In an attempt to address these challenges, this paper analyses the impact of emergencies on the overall progress of rail freight transportation. The aim of the paper is to explore the possibilities of using regional lines as alternative routes in the event of an emergency on the corridors, and to describe the possible benefits for end users, but also for the carriers themselves, in case of using regional lines as alternative routes. The article also compares the strengths and weaknesses of regional lines in their use in rail freight transportation, with an emphasis on their ability to ensure reliable transportation of goods. The article compares and evaluates selected routes in the Czech Republic from an economic and operational point of view, which may help carriers react better and more efficiently to unexpected events that may occur on the railway infrastructure.
