USA HISTORY

Detailed explanation-1: -Not only did the railroads transport raw materials used in industrial production, such as coal and iron ore, the railroads were also one of the largest consumers of raw materials in their own right. The growth of railroads thus led to growth in other industries, such as timber and coal.

Detailed explanation-2: -Railroads became a major industry, stimulating other heavy industries such as iron and steel production. These advances in travel and transport helped drive settlement in the western regions of North America and were integral to the nation’s industrialization.

Detailed explanation-3: -They contributed to economic dislocation and depression, encouraged corruption, and destroyed local economies and communities. The builders were inept and built shoddy products. There was abuse of labor and destruction of the labor movement.

Detailed explanation-4: -With the proliferation of railroads, faster travel became possible across many cities and travelers could sometimes arrive at an earlier local time than the one they had left. Due to this lack of time standardization, schedules on the same tracks often could not be coordinated, resulting in collisions.
