Answer:During the growth of the railroad system, Americans did begin to measure time using time zones, since after the 1820´s the industrial revolution had begun and the creation of more jobs and a more labor-based industry that needed more technical, machine based manufacturing. And derived from that, came a new time measure, which meant production efficiency increased, which led the way to economic growth.
In fact, after a single clock was added to the trains, passengers´ security increased because they were able to get from point A to point B in the time needed. Rail companies did begin to create their own styles of rails and tracks. Some track designs had different size of gauges, which varied from 2.5 to 6 feet. Transcontinental Railroads changed history, after Union Pacific and the Central Pacific railroad companies united to make what was known as the first Transcontinental Railroad in the U.S., which allowed people to travel from New York to California in just a few days, rather than weeks. This meant that railroads had to withstand different scenarios and climates, for that matter, railroads had to last and also be versatile since they were not only going to carry passengers, but merchandise as well, and they had to be able to carry both without needing extra changes. Another advantage was the price of the property where any railroad tracks passed increased. Americans started buying land in hopes that railroads would pass by their land and make the value of their property to increment.
