How did the railroads in the west influence miners, ranchers, farmers, and Native American Indians?I am supposed to write a short paragraph for...

The railroads primarily helped most businessmen--including miners, ranchers and farmers--to move their merchandise at a much faster speed to customers in other parts of the United States. They were also able to purchase merchandise from the East and West Coasts and have it delivered at a much quicker rate. Railroads soon reached nearly every corner of the United States, enabling people and products to move to these locales as well.

As for the Indians, the railroads brought more people and more industry, causing the Native Americans to move from their own lands to new ones and, eventually, to the reservations which ended their old way of life.
