COMMUNICATIONS
In the Wild West, mail was delivered by stagecoach. But it took a long time. So, in 1880, the Pony Express, a relay of horse riders from Missouri to California, was founded and reduced the delivery to eight days. William Cody and Calamity Jane, two famous figures of the Old West, worked for the Pony Express. However this service only lasted one year: it was replaced by the telegraph system.
Eight years later the eastern and western railways were joined and the transcontinental line was completed. Railroads had a profound social effect as more and more women and children migrated, developing a real family life out west.
