Time Zones:

Before the 1880's each community set it's clock by the sun's position at noon. Having many different time zones, interfered with train scheduling. It even threatened passengers safety at times. Trains could travel the same track, collisions could result from scheduling errors caused by all the different times. To make this all safer and more reliable, in 1883 the American Railway Association divided the country into four time zones. This change didn't get ratified by the government until 1918.
