In the late 19th and early 20th century, both the Southern Pacific and Union Pacific Railroad were built through the San Jose Creek valley in what is now Industry. The Union Pacific would establish a major railyard at the Marne siding in what is now Industry. Valley Boulevard, a major artery connecting Los Angeles with points east, was also laid through what would become the City of Industry. The presence of the railroads and Valley Boulevard would lead to the development of warehouses that became a large part of Industry's economy.
