Abstract: This paper analyses the evolution of passenger railway accessibility in Portugal over the fifty-year period from 1971 to 2021, combining historical institutional analysis with a newly constructed longitudinal spatial database of railway infrastructure and services. The study documents how waves of line closures, service restructuring, and selective modernisation reshaped the geography of rail accessibility across Portugal’s municipalities. The empirical analyses reveal a pronounced asymmetry in the evolution of rail accessibility. While the overall share of population served by rail declined only moderately, the territorial coverage of the railway network contracted sharply, particularly between 1988-1992 and again between 2008-2013. The elimination of rail services disproportionately affected low-density municipalities in the interior of the country. At the same time, long-distance and suburban services experienced significant improvements in travel times and service levels, reflecting targeted investment and operational modernisation along a limited number of strategic corridors. The results show that gains in long-distance accessibility, especially along the Lisbon-Porto axis and other major intercity routes, coexisted with a marked deterioration of regional connectivity. Urban and suburban rail services also benefited from relatively stable or increasing service levels, reinforcing the concentration of accessibility gains in metropolitan areas. The analysis points to a process of functional specialisation of railways in Portugal, with systematic prioritisation of long-distance intercity services and urban metropolitan services over regional services, with significant implications for territorial cohesion.
