5. 요약 (Summary)
Growing western cities gave birth to the American railroad under the cooperation
between the government and private companies. Since preexisting short railroads and
canals weren’t enough, there was a rising demand for railroads to the expanding
western cities. Therefore, government took in charge to devise optimal routes for
railroads and cooperated with two companies to develop each half sections of the
whole route. However, workers in the eastern half were conscripted after the
breakout of the Civil War while the western half continued its construction. As the
western half advanced its work faster, the new junction was moved to the eastern
part. By the 1880s, the whole country was linked by railroads.
