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.
