Railway construction and industrialization played an important role in reshaping the urban morphology of inland resource-based cities in Republican-period China. Taking Taiyuan during 1912–1937 as a case study, this paper examines the spatial association between railway corridors and industrial locations and discusses how this relationship contributed to the reorganization of urban space. Historical maps, railway maps, local gazetteers, archival materials, and existing literature were integrated into a historical GIS database. Kernel density estimation, railway buffer analysis, mean-center analysis, and standard deviational ellipse analysis were used to reconstruct the staged evolution of industrial nodes and railway corridors. The results show that Taiyuan’s industrial space evolved from a scattered point-based pattern to a railway-oriented axial-belt layout and then to a polycentric industrial corridor. Industrial nodes gradually moved closer to railway lines, while the mean center of industrial distribution shifted from the traditional city toward railway-related industrial districts. The findings suggest that Taiyuan followed one possible railway–resource–industry pathway shaped by railway construction, resource endowments, provincial industrial policies, land conditions, and the inherited urban fabric. This study provides historical spatial evidence for identifying railway–industrial heritage corridors and understanding inland industrial urban form.
