Timshel
"Timshel" is the ninth episode of the first season of the American television drama series Hell On Wheels, which aired on January 8, 2012 on AMC. It is written and directed by John Shiban. In the episode, Cullen Bohannon ( Anson Mount) and the search party find the Cheyenne who attacked the surveyor's camp and later derailed a train; Elam ( Common) and Eva ( Robin McLeavy) discuss their future, before getting a strange visitor; and the railroad crew reaches the important 40-mile mark. The episode title has several meanings – from the Mumford & Sons song of the same name, which was heard in the episode, to the actual Hebrew word translation of man's triumph over sin.
