Why was the transcontinental railroad route across indian territory ruled out?

If I remember my history right it was ruled out because of Indian burial grounds much like the lakota tribe is worried about with the Pipeline up in montana 

I believe that the answer to the question provided above is that the transcontinental railroad route across indian territory ruled out because of the aggression the indians are doin towards the train.
Hope my answer would be a great help for you.    If you have more questions feel free to ask here at .
