> Japan followed a similar path as the West before World War II, but afterwards diverged. As in the West, railroading started out very laissez-faire in the 19th century, but came under state control in the beginning of the 20th. But after World War II, while nearly all railways and intracity buses in Europe and North America were nationalized, Japan stayed its pre-war course, with the railway industry retaining its sizable minority of private firms.
They became further privatized in the 80s, and now there are multiple competing rail companies in Japan. It's my understanding that their business model is to build rails, run near breakeven on the actual trains, and then capitalize on the businesses that spring up around the lines (by purchasing nearby real estate and opening up shopping centers & restaurants).
