When I was in Scotland mid 1970s, mere student-plus, I was on the periphery of all this (sometimes closer), in Glasgow and Edinburgh, hence all my accounts of the Class 27 push-pull. I'm still appalled at some of the ludicrous ideas that rank amateurs (ie the councillors) in Glasgow played in enforcing their ideas on the professionals and on the inhabitants of the city. There was an extraordinary desperation to put people into public housing, managed of course by their own city housing department. Areas like that all around Kings Park station, mentioned above, were regarded with a real sneer because they were middle-class owner occupied properties - an attitude that even made it into the Gregory's Girl film, set in 1980 in Cumbernauld, another Glasgow overspill, with scripted comments about the people "up in the private houses".
Just to give you some idea of what can be done, this area in Edinburgh, Dean Village, was a ruin then, more than Gorbals, and many of the old buildings were without roofs. Nowadays, with an enterprising urban renewal, they sell for £1/2m.

It wasn't just the Blue Trains, a lot of government money was made available in the 1960s-70s for the motorways, and also the Glasgow Underground rebuilding. That last, unfortunately, led to some dreary mass-brick boxes being provided for surface stations. I would apologise for those, I didn't do them myself but they were done by the guy at the next desk, as described here
