2īecause the development of standardized time was transportation-driven, the government coordination of time zones was handled by transportation agencies. 1 As a result, the major railroad companies began to operate on a coordinated system of four time zones starting in 1883. 2 Due to this lack of time standardization, train scheduling proved difficult to coordinate, resulting in missed connections and collisions. 2 With the proliferation of railroads, faster travel became possible across large geographies, and travelers could sometimes arrive at an earlier local time than they had departed. 1 The resulting time differences between adjacent towns and cities were not critical when it took days to travel from place to place.
