Mining, textiles, agriculture and timber industries grew due to the expanding railroads
Railroads expanded on the mining frontier to transport mining equipment, supplies, and extracted minerals efficiently and at a lower cost. The presence of railroads encouraged the growth of mining towns and made it easier for miners and investors to access remote areas with valuable mineral resources. Additionally, railroads provided a means to transport labor to mining sites, contributing to the overall development and success of mining operations on the frontier.
In the US and in many parts of the world, railroads are the main form of transportation for various types of minerals and ores that are part of the mining industry. With proper transportation, the miners have an ongoing way to transport the products mined from the earth. Often the railroads lead to a water port and the mining products can be shipped via waterways, canals and seas to their proper destination.

No one person invented the railroad as it evolved over hundreds of years. The first railroads did not have locomotives. Richard Trevithick is credited with creating the first successful steam locomotive. George Stephenson is credited with expanding the use of railroads from being a part of a mining operation to the first passenger railroads.
