Railroads became a major industry, stimulating other heavy industries such as iron and steel production.
Railroads used four U.S. time zones, an idea that had been proposed 11 years earlier by Charles Dowd, a Yale-educated school principal. The time zones, Eastern, Central, Mountain and Pacific, which we still use today.
The first air brake invented by George Westinghouse revolutionized the railroad industry, making braking a safer venture and thus permitting trains to travel at higher speeds.
Transcotinental railroads became the first continuous railroad line across the United States. It was constructed between 1863 and 1869
The birth of the modern electric utility began when Thomas Edison invented the practical lightbulb in 1878, and, to spur demand for the novel invention, developed an entire power system that generated and distributed electricity
The phonograph was invented in 1877 by Thomas Edison. The phonograph was the first device to be able to reproduce the recorded sound.
The lightbulb worked by sending an electrical current through two carbon electrodes separated by an air gap. The heat vaporized the carbon at the tips of the electrodes, producing a bright light. Electricity contributed to the growth of transportation. The lightbulb also extended the workday into the night, and allowed people to navigate and travel safely in the dark.
Alternating Currents allows for greater efficiencies by reducing power loss and enabling power transmission at higher voltages. This revolutionized the way we use electricity today, propelling us into the modern age of convenience and comfort.
A website I found said "By reducing labor costs, such machines not only reduced manufacturing costs but lowered prices manufacturers charged consumers. In short, machine production created a growing abundance of products at cheaper prices."
The railroads, the newspapers, and the stock markets have communicaions to thank to help them succeed. None of the businesses could have achieved such a big role in American life without communication
The telegraph helped businesses succeed so much more. Railroads also used the telegraph to schedule trains from station to station, allowing their trains to run faster and safer
Telephones made it easier for businesses to communicate with each other. They made ommunication in general so much better and easier
PBS states "Steel meant more jobs, national prestige, and a higher quality of life for many. For Carnegie's workers, however, cheap steel meant lower wages, less job security, and the end of creative labor. Carnegie's drive for efficiency cost steel workers their unions and control over their own labor."
The Bessemer Process making steel cost-effective and mass-producible. Steel became a very big construction material mainly because of this process and invention.
