The correct answer is A) they were displaced from their tribal lands.

The impact that the expansion of railroads in the west had on the American Indians who lived there was that they were displaced from their tribal lands.

Railroads changed the life of people in America. There were many benefits such as better transportation of people and goods and the increase of trade. But among the disadvantages was the wat railroads affected the Native American Indians. Most of the Native American Indian tribes were displaced from the lands and sent into reservations. Railroads represented opportunities for white settlers but hurt so much the life of the Indians and its independence. Many disputes about the land were held but with negative results for the Indian tribes.
