What was the purpose of the transcontinental railroad?

Being enslaved: Getting whipped, working from sun up to sun down either in extreme heat or cold, getting bitten up by bugs and getting no help, having to worry about if your gonna eat today or eat a little, have to worry if the massa if gonna get mad and kill you or another slave or beat them, also having to live without being able to learn beacause if you did, you would get killed.

Freed slave: You are still not equal to the whiteman, you constantly had to worry about being lynched, you could barely be able to learn, you were poorly compared to everone else, you also did not make a lot of money either.

Hope I helped ^-^. Mark as brainliest!
