Road-rail substitution in the early motoring age, 1910-1938

We investigate the closures of railway lines in France between 1910 and 1938 when France experienced rapid network shrinkage. Multiple hypotheses have been put forward, ranging from the financial troubles of railway companies, the competition of automobiles and interurban coach services, and the rationalisation of the network leading to its nationalisation and the creation of the SNCF in 1938. We provide a quantitative assessment of these factors using newly assembled data on road and rail networks and the first historical metric for passenger traffic at the station level. Finally, we analyse the impact in terms of spatial inequality.
