they were displaced from their tribal lands.
they moved into towns and lived among the new settlers.
they stopped farming and took jobs in factories.
they were forced to move to mexico.

Explanation:

The expansion of railroads in the West led to the displacement of American Indians from their tribal lands. As railroads were built, more settlers came, and the government often took Indian lands for the railroad projects and for the settlers. American Indians did not generally move into towns to live among new settlers in large numbers in a voluntary way related to railroad expansion. They also did not stop farming and take factory jobs in response to railroad expansion (factory jobs were more in the East in that era). And they were not forced to move to Mexico en - masse due to railroad expansion.

Answer:

They were displaced from their tribal lands.
