According to Krugmen and Wells, a natural monopoly may arise when high fixed costs create a barrier to entry in a market. Railroads are one example of a natural monopoly. The sheer amount of capital it takes to start a railroad presents this barrier to entry. In order to move the first carload of freight a massive amount of money needs to be invested in infrastructure (track, locomotives, cars), and a massive amount of personnel need to be hired to operate and maintain the railroad. There are few railroads in the United States, and each one tends to operate in a particular are of the country with the exception of Amtrak. These rail lines are Union Pacific, BNSF, Kansas City Southern, CSX, and Norfolk Southern.
The government regulates natural monopolies extensively so that they don’t restrict the production of their product to inflate their profits on the backs of consumers.
