Materials used to build the central pacific railroad were shipped

Materials used to build the central pacific railroad were shipped around South America

Explanation:

Before the continental railroads, the travel through stagecoach was costly, and it took a long period to travel. However, there were available options for going through the sea using the South American path, but the distance that was covered was also long.

This was the reason that the South Americans opted to provide materials for construction of railroads to safe people from traveling for long periods and in long distances. And also ensure products that were shipped reached their designated destination earlier enough.
