What works in Europe and Asia won't in the United States. Even abroad, passenger trains are subsidized. But the subsidies are more justifiable because geography and energy policies differ.
Densities are much higher, and high densities favor rail with direct connections between heavily populated city centers and business districts. In Japan, density is 880 people per square mile; it's 653 in Britain, 611 in Germany and 259 in France. By contrast, plentiful land in the United States has led to suburbanized homes, offices and factories. Density is 86 people per square mile. Trains can't pick up most people where they live and work and take them to where they want to go. Cars can.
Distances also matter. America is big; trips are longer. Beyond 400 to 500 miles, fast trains can't compete with planes. Finally, Europe and Japan tax car transportation more heavily, pushing people to trains. In August 2008, notes the GAO, gasoline in Japan was $6.50 a gallon. Americans regard $4 a gallon as an outrage. Proposals for stiff gasoline taxes (advocated by many, including me) go nowhere.
