Europe and Japan faced the same automakers, oil companies, and postwar boom as America and chose differently. They nationalized bombed networks, electrified them, taxed petrol heavily, and ran trains as a public service, producing the Tokaido Shinkansen in 1964 and the TGV in 1981. They did not reject the car, though; they kept both systems.

Still debated
Europe did not reject the car; it built roads without liquidating rail. Scholars split on whether density and geography explain the outcome or policy shaped the geography. Public ownership is credited with saving the trains but also with JNR's ruinous debt.
