Map of ibiza for While such a claim seems to have a certain logic, and may act as a useful corrective in our thinking about the indispensability of the railroads, much of the evidence marshaled by its advocates seems to give a pretty clear impression of the revolutionary effect of the railways on the American economy. For instance, in 1851 52 boats carried six times as much freight as trains in America, yet as quickly as 1889 90 trains were carrying five times as much freight as boats. And the comparative advantage of trains was not just their cost (for prices kept falling, commodity transport by rail dropped from 1.925 cents per ton mile in 1867 to 0.839 cents in 1895), but the fact that builders directed rail routes in a way that was not possible with river transport, and in doing so a national market was established across the United States, at precisely the time that a unitary political state was being formed. Just as had been the case in France, the state encouraged the development of rail networks through the granting of concessions, tracts of land, and grants. Such agreements did not, of course, benefit all Americans, and we find a close connection between the colonial expansion westward, the development of railways, and the destruction of Native-American cultures (as has been amply replayed in so many western movies).
