How did the transcontinental railroad further the industrial revolution?

The transcontinental railroad furthered the growth of the Industrial Revolution. Industries had been expanding as Americans moved westward toward the Mississippi River. Once people moved beyond the Mississippi River, businesses grew even more. The building of the transcontinental railroad furthered the growth of American industries. The construction of the transcontinental railroad meant that industries had to provide the products and materials needed for building the railroad. More steel was needed for the tracks, and eventually, more railroad cars and engines were needed.
With the building of the transcontinental railroad, people began to move further west than in the past. These people needed products so they could live in these areas to which they were moving. Businesses needed to grow to meet the increasing demand for products. As a result, businesses expanded westward. New factories were built in the West to make products for the people who were moving and living there.
The transcontinental railroad significantly impacted the growth of the Industrial Revolution.
