Unlike road or river networks, railway networks automatic generalization are missing to properly handle the detailed networks provided in current geo-datasets like OpenStreetMap. This paper proposes automatic methods to automatically identify key structures of railway networks, such as parallel main tracks, or fan and pack patterns inside large train stations. Then, algorithms based on the detected structures are proposed to generalize the railway networks. The algorithms are tested on real datasets, including OpenStreetMap data.
