What was the political impact of the transcontinental railroad?

Answer 1

It was the plans for building this railroad that divided the nation.

The North wanted it to go via Chicago, the South wanted it to go via New Mexico.

To get the South to agree the Chicago route, Congress had to appease them with the Kansas-Nebraska Act - holding a local vote on slavery, and allowing the possibility of new slave-states.
