"Hell On Wheels" Season 2 will be action-packed for Cullen Bohannon (Anson Mount) if this new, exclusive promo is any indication.

"This rebel must be dealt with," Thor "The Swede" Gundersen (Christopher Heyerdahl) threatens in the promo, referring to Cullen.

The "Hell on Wheels" Season 2 artwork gives a glimpse into Season 2's returning main characters: Elam Ferguson (Common), an emancipated slave; Thomas “Doc” Durant (Colm Meaney), a greedy entrepreneur, Lily Bell (Dominique McElligott), a newly widowed woman; and Cullen Bohannon, a former Confederate soldier.

"Hell on Wheels" Season 2 will continue to tell the post-Civil War story of Cullen Bohannon centered around the construction of the first transcontinental railroad and his journey west with a traveling town.

"Hell on Wheels" Season 2 premieres Sunday, August 12 at 9 p.m. ET on AMC.
