With the completion of the trans-continental telegraph line, the Pony Express is discontinued. The Pony Express consisted of relays of men riding horses carrying saddlebags of mail across a 2,000-mile trail. Eventually, the service had more than 100 stations, 80 riders, and between 400 and 500 horses. The express route was extremely hazardous, but only one mail delivery was ever lost.
