Yes, fascinating, and those are superb coaches now. Passengers too - that raises the bar substantially. I look forward to seeing the complete train behind a Peak. Somewhere tucked away I have a rake of Airfix Mk2D/E blue and grey coaches which were intended to form a 1970s/80s ECML train behind a Deltic. As they've never been run, it's time to ferret them out, but the equally unused Mainline(?) Deltic didn't have any window glazing, which was a bit of a turnoff.
