Channel 5 also did the "Ice Road Truckers" and there is always a drama in the run up to each advert break - "Will he die of frostbite", only to find after the ad he didn't. Identical style.
That criticism aside it's a very light programme that shows off the chosen staff in a very good light. And very laid back.
Great scenery and superb rail shots.
Really enjoyable (despite being filmed north of the Tamar).
No offence intended to anyone north of the Tamar by the way
