In the Canadian wilderness, an elite army of workers venture through the depths of winter to keep the country’s most remote rail lines running.

This series meets the toughest and most resilient train crews who, every year, battle ferocious weather and treacherous terrain to keep the railways people depend on, flowing. Despite the constant threat of deadly avalanches, icicles and rockslides, the freight and passenger trains remain vital to the survival of mountain industries and isolated communities that are served en route. And, with no option of shutting down, these teams are on a fatal mission to ensure the country's oldest, most critical infrastructure keeps rolling.

Rocky Mountain Railroad premiered in February 2018.
