Rail road companies facilitated settlement of the Great Plains because it provided a means of transportation for settlers to get to the location.

The area was a large expanse of flat land making it easy for newcomers to establish agriculture.
The government was connected because you were not allowed to assemble back in that time, so the government could storm in any time they deemed suitable to them if they had proper suspicion.
