I came across these videos about the construction of the Victoria Line the other day:
. I found them interesting not so much for the detail of construction techniques, but for the scenes of everyday 1960s life at the edge of the works, and the culture of the time.
I think the biggest contrast with, for example, the promotional videos Crossrail are putting out today, is the sight of workmen going about their business without hard hats, gloves, steel toecapped boots or high-visibility clothing. Particularly in the sequences where there are cranes swinging huge steel girders around at head height.
