Four representations of the Swiss railway network

This dataset contains four representations of the Swiss railway network as of 2025. The dataset is based on data from the Open Data Platform Mobility Switzerland (ODPCH, https://opentransportdata.swiss/en/). In all four representations, the set of nodes corresponds to the complete set of train stations in Switzerland. The first three representations are static networks that differ in how edges are defined:The first, called Space-of-Changes (SoCha), includes a directed edge between any two stations connected by a direct service that requires no train changes.The second, Space-of-Stops (SoSto), includes a directed edge between any two stations served by at least one non-stop train.The third, Space-of-Stations (SoSta), includes an undirected edge between any two geographically adjacent stations.Finally, the fourth representation is a temporal network, where each edge represents a train connection annotated with its start time and duration.The dataset consists of the edgelists for the four representations (filename edgelist_*.csv), the nodelist (nodelist.csv), as well as two files, edges_removed_SoSta.csv and edges_added_SoSta.csv, which contain edges that were manually removed and added, respectively, in order to comply with the definition for the Space-of-Stations representation.

本数据集包含截至2025年的瑞士铁路网络四种表征形式。本数据集基于瑞士交通移动开放数据平台（Open Data Platform Mobility Switzerland，ODPCH，https://opentransportdata.swiss/en/）的公开数据构建。所有四种表征形式均以瑞士全部火车站的集合作为其节点集。前三种表征均为静态网络，三者的核心差异在于边的定义规则：第一种表征命名为换乘空间（Space-of-Changes，SoCha），其包含任意两个由无需换乘的直达列车服务连接的车站之间的有向边；第二种表征命名为停靠空间（Space-of-Stops，SoSto），其包含任意两个被至少一班直达不停站列车服务覆盖的车站之间的有向边；第三种表征命名为站点空间（Space-of-Stations，SoSta），其包含任意两个地理相邻的车站之间的无向边。第四种表征为时序网络，其中每条边对应一趟列车运行班次，并标注了其发车时刻与运行时长。本数据集包含四种表征的边列表文件（文件名格式为edgelist_*.csv）、节点列表文件（nodelist.csv），以及两个辅助文件edges_removed_SoSta.csv与edges_added_SoSta.csv，分别用于存储为符合站点空间（SoSta）表征的定义要求而手动移除和新增的边。
