The Railway Nationalization Act brought the trunk network of major private railways under state ownership in 1906-1907, with compensation largely paid in government bonds. The measure is central to prewar Japanese state-building: it gave the state direct control over core transport infrastructure, improved network coordination for freight and mobilisation, and reduced the role of competing private trunk-line firms in a sector treated as strategic rather than merely commercial.
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.
