Hell on Wheels is not only coming back for a fourth season, it’s also getting more episodes than ever before. The Western has been picked up for 13 episodes, which will premiere next summer (the first three seasons had 10 episodes each).

The move follows the show’s successful season 3 transition to what’s normally considered a programming dead zone — Saturday nights. AMC programs Western movies on Saturdays, so having an original series from the same genre seemed like a natural fit. In fact, Hell on Wheels averaged 3.3 million viewers with three days of DVR, an increase from the second season.

There’s still word, however, on the fate of AMC freshman drama Low Winter Sun.

“[Showrunner] John Wirth and his team on both sides of the camera delivered a remarkable third season and Hell On Wheels fans responded,” said Charlie Collier, AMC president. “We are so proud of this show and congratulate everyone who has contributed to its success. AMC has served passionate Western fans for three decades, so it is particularly gratifying to see these viewers capping off their Saturdays with an original Western on what has historically been a tough night of the week for television.”
