The first 10 episodes will air consecutively through Saturday, Oct. 4, and then the show will take a month-long hiatus before returning on Saturday, Nov. 8 to air the final three episodes of the season. Season 4 will chronicle the expansion West along with the development of the railroad, as the government, businesses and individuals compete for control of Cheyenne, Wyoming - the most important railroad hub in the country. The consequences of the stories we told last year will continue to reverberate throughout the season, and fans can expect to see some shocking events that will not only change the lives of our characters, but the landscape of the series as the railroad continues its relentless march westward.
