The decree-law of 31 August 1937 reorganised the railway regime and cleared the way for the creation of the Societe nationale des chemins de fer francais (SNCF), which began operating on 1 January 1938 as the dominant national railway operator. The state responded to the financial weakness and fragmentation of the major railway companies by fusing the network into a single state-backed enterprise with coordinated tariffs, investment, and management. The measure was a classic strategic-network nationalisation rather than a general socialisation of industry.
Per invariant 3, reforms are scored by what they did on each channel-separated axis, not by the party that enacted them. This fingerprint is how the policy-match engine finds historical analogues.
Explicit links are curated by the author. Inferred links are hypotheses in the library that test the same axes this policy moved — the framework's answer to "what does the data say about a policy like this?".
Ranked by axis-fingerprint overlap with this policy. Direction match bolded — those are the closest historical analogues. Shape of the match is what drives policy-outcome comparison, not the country or party label.
