The sustainability of urban development is related to the transport system in cities, including railway transport. Intra-city transport infrastructure, including railway, is one of the most important elements of the quality of the urban environment. In this paper, railway traffic corridors are observed through two basic components: the linear space of intra-city railway corridors and the surrounding area of railway stations. The paper presents the basic theoretical and practical principles of reconstruction of railway intra-city corridors and railway stations within cities. Railway corridors have the potential to stop being an obstacle to connecting parts of the city, while railway stations have the potential to become central places of city traffic, accompanying urban functions (commercial, service, public) and identity places of the city. Intra-city railway corridors in Croatian cities are important for the modernization and technical reconstruction of the railway as a transport system, but also as a factor in the urban renewal. The paper examines the reconstruction of the railway within the city of Zagreb, which was technically reconstructed but the urban reconstruction of the intra-city railway corridor was missing. The paper cites the city of Osijek as a positive example of the beginning of the urban renewal of the area around the Osijek railway station. In conclusion, it is pointed out that the reconstruction of the railway in the city should include the urban reconstruction of the area of the railway corridors, not only the technical and safety reconstruction of the transport system, and that the railway stations should once again become places of the city's urbanity.
