This data set contains the rail infrastructure data for Oslo Central Station, the station for which we de-veloped an algorithm for optimal dispatching in [1]. The infrastructure data was collected from restricted access schematics of the signaling and rail infrastructure in Oslo Central Station and on the connected lines. The data had to be collected by hand since the schematics were only available as images. The data set details most of the track infrastructure in the station but is not entirely complete when it comes to depots and other technical areas. The set contains a sample one-hour schedule based on actual traffic at the station. Based on these data, researchers can construct their own entirely realistic instances of the dispatching problem for large passenger stations, which they may, in turn, make freely available. This will allow the community to compare the performance of various approaches to the problem rigorously.(c) 2022 Published by Elsevier Ltd.
