What specific evidence supports the statement that "the construction of the transcontinental railroad was disastrous for the native americans of the great plains"?

The transcontinental railroad decimated the herds of buffalo that the Indians were dependent on, and the railroad drastically reduced Native American land ownership.

Explanation:

Rail associations with the Great Plains demonstrated devastation. In the wake of securing ponies, Indians there had turned out to be intensely reliant on the field’s buffalo for nourishment, cover, apparel, exchange, and substantially more.

In 1872 it was discovered that buffalo covers up could be handled into business calfskin, and white stow away trackers promptly set out to fulfill that need. Inside ten years, they had driven the massive number of creatures to the skirt of elimination.

The butcher would have been improbable, most likely incomprehensible, had railways not given the way to deliver the stowaway and bones off to eastern industrial facilities.
