AMC announced that the show will expand to 13 episodes and return to US screens in the summer under showrunner John Wirth.

AMC president Charlie Collier said "John Wirth and his team on both sides of the camera delivered a remarkable third season and Hell on Wheels fans responded. We are so proud of this show and congratulate everyone who has contributed to its success."
