Today, AMC released a trailer as well as the poster for the first half of the fifth and final season of Hell on Wheels.

The trailer, "Changing Sides," features a first look at Cullen Bohannon (Anson Mount) as he begins work for the Central Pacific Railroad. Click here to watch the trailer.

The poster features the tagline "All Roads Lead to Hell," and depicts Cullen Bohannon standing at a railroad junction. Behind him, the Central Pacific's Chinese workers can be seen toiling on the western end of the Transcontinental Railroad, with the imposing peaks of the Sierra Nevada mountains visible in the distance.

For those new to the show, Hell on Wheels looks at the institutionalized greed and corruption behind the building of the Transcontinental Railroad as the race between the Central Pacific and Union Pacific intensifies. In Season 5, Cullen Bohannon finds himself a stranger in a strange land: Truckee, California. Home to the headquarters of the Central Pacific Railroad, this rough mountain railroad town teems with thousands of Chinese workers who are foreign in language, culture, and traditions. While grappling with the challenges of corralling his new workforce, Cullen must lead the Central Pacific’s herculean effort to tunnel through the Sierra Nevada mountains, sometimes achieving only inches a day as the race to complete America’s first Transcontinental Railroad continues.

The first half of the fifth and final season of Hell on Wheels premieres Saturday, July 18 at 9/8c on AMC.
