Not only is it "not far off" it's locally higher. Ohio is more densely populated than Spain. They even both have a city called Toledo. The difference is the smaller city in Spain has a high-speed rail link to the capital with 6 trains per day, while the larger city in Ohio has only two conventional trains per day, neither of which serve the nearest city, Detroit, only 60 miles away.

In any sensible universe, the major cities of Ohio would be connected to each other, Detroit, Chicago, and Pittsburgh by high-speed rail.
