The second season premiere of AMC’s Hell On Wheels last night drew 2.5 million total viewers; 793,000 of them in the 18-49 demographic; 1 million in 25-54. That was down from the series’ first season opener (4.3 million) and closer (2.9 million). The period Western was hit with a double whammy as it aired against the closing ceremony of the London Olympics at a time when AMC’s viewership continues to suffer from the lack of carriage on Dish Network. Add to that the fact that Hell On Wheels is a self starter this time around vs. airing behind hit The Walking Dead last season and that its ratings declined for most of  its freshman season, and the drop is not that surprising but still alarming for the drama’s long-term prospects if it follows a ratings trajectory similar to Season 1.
