In a short paragraph, describe two examples of how changes to the railroad american industries grow

First, they made settlement of the West possible after the Civil War by connecting farmers (and miners, ranchers, loggers, and others) to markets.

Second, railroads helped to integrate different regions of the country economically.

Explanation:

A railroad is a road laid with rails, usually in pairs of continuous lines forming  tracks, on which trains run for the transportation of passengers and goods. Railroads are considered the most efficient form of transportation. They are widely used to convey heavy and bulky commodities over long distances. For example, in the year 1880, the transcontinental railroad was transporting $50 million worth of bulky goods each year.

The American industry grew tremendously with the new modifications to the railroad. The new railroad system made transportation of bulky cash crop produce easier from the farming site to the processing site. Most of the farmers could not afford an expensive means of transportation.  

Secondly, railroads helped people to connect to different parts of the country at a reduced cost. People could move from one region to another through the use of the rail system with minimal expense.
