One way in which the completion of the Transcontinental Railroad affected companies that made products was that "Companies could ship goods cheaply over long distances," which greatly increased profits. 

Answer:

Companies could ship goods cheaply.

Explanation:

On May 10, 1869, construction of the Transcontinental Railroad was completed (although the connection between the coasts was actually completed the following year). This established a transport network that would become central to the US economy, as this revolutionized transportation to the companies that manufactured products because these companies could transport their products at a lower price and with greater speed.
