TV WEEK: Hell on Wheels season four billboards...

Whoever said Westerns don't work on TV should be eating their words, as Hell on Wheels enters its fourth season.

The railroad at the heart of this drama continues its relentless march westward and we'll discover there are consequences from last season, plus plenty of new shocks in store for these new episodes.

Anson Mount and his co-stars Colm Meaney and Common will discover that 'Hell Ain't Civilized' and that conflicts with government and big business are just as dangerous as men with guns.

These arresting Hell on Wheels season four billboards were spotted along Sunset Boulevard and Highland Avenue on July 10, 2014.

If you're a fan of the show which centers on the gritty dramas, greed and corruption surrounding the temporary traveling town which services the construction of the first transcontinental railway, be sure to also check out these Hell on Wheels season one, two and three billboards.

Hell may not be civilized, but the wheels only keep turning as long as you keep tuning in.
