Abstract
This article presents the history of identifying the causes of emergency threats and the repair of a section of the railway line within the Wolin National Park. The author focuses on issues related to the legal aspects of environmental protection in a specially protected area that arose during the design and execution of repair works on the railway infrastructure. Numerous meetings between the Management of the Railway Line Department in Szczecin and the Management of the Wolin National Park, with both sides fully understanding the essence of technical and environmental problems of the project, led to a consensus. The scope and method of repair were established, allowing the minimization of the negative impact of the investment process on the park’s natural and environmental values while ensuring the safety of train traffic. Despite the typical and straightforward nature of the repair task, due to environmental protection constraints, non-standard construction problems were encountered, which consequently increased costs and extended the construction time.
