Railroad companies were able to standardize their timetables in 1883 by implementing standard time zones. In 1870, Charles F. Dowd proposed four standard time zones, which were later revised to be based off Greenwich-Median time, making it easier for businesses to operate across states. Previously, each railroad had its own arbitrary time system, causing confusion and inefficiencies.
