The effects of the transcontinental railroad on the a united state

The building of the Transcontinental Railroad had a huge impact on American life and economy. It greatly sped up travel time. Before the railroad, you needed around six months to travel from the coast of California to New York and after it started with the operation you needed only around one week. This meant more expansion of the industry, trade, businesses, and expansion of populated areas. Unfortunately many Native American tribes were displaced and the US military was called in to fight the tribes.
