Answer:
The completion of the Transcontinental Railroad was a major technological feat for the improvement of commerce and trade of the products made by companies.
Explanation:
The First Transcontinental Railroad, also called the Pacific Railroad, was constructed in 1869 by the Central Pacific Railroad and the Union Pacific Railroad to join the eastern and western regions of the United States. This Transcontinental Railroad enabled companies to transport their products across the US more rapidly by land since transport by water (shipping) took several days. As a result, their goods and products could be sold and traded more efficiently and in less time, which resulted in greater wealth for these companies (and for the American society too, of course). In addition, as commerce accelerated, they were able to start producing and selling much more than before.
