Railroads could transport cattle from the west, so farmers did not feel the need to move west. Which affected Western migration.
Railroads played a key role. Trains carried natural resources from the west to eastern markets. Trains also brought miners, farmers, and ranchers to develop the land.
Railroads reduced travel time between the east and west thereby eliminating many hardships for people and animals. They also reduced the cost of transporting freight over great distances.
