I thought the opening sequence was filmed in Heptonstall. Maybe Dave Hanson might recognise the place. The powers that be discourage driving through the village, the car park is at the bottom of that main street.

It seems to have been shot trying to use the perspective from the northern end of Ribblehead viaduct. If you were to follow the gravel track towards the viaduct and then keep straight on where it swings under the viaduct, ie follow the 3peaks track, you will, I think, be able to vizualise the viewpoint that they had tried to create. Far from being a deserted place in the summer there are usually over 30 cars parked around the place during the day and there is often a tea van parked there. Often on a summer Saturday there will be over 100 walkers doing the Yorkshire 3 peaks.

If the series creates interest in the labours of those who worked on the S & C, particularly during its building, that would be good. They were hard people who's lives were shortened by accidents, diseases and the harshness of the life they had to follow. I take my hast off to them.
