The train crash was filmed in a disused limestone quarry in Stoney Middleton, Derbyshire, it attracted a very large audience of on lookers. But only one go at it not the repeated shits in the video. Mossy
The side opposite the railway track is a very famous Derbyshire climbing area, the side filmed is/was far too loose for climbing on, although I think there was some exploration by some seriously %$£^^%$ climbers, I think 2 rock climbs were recorded. When I climbed down there regularly in the 70s and 80s it was still being quarried, so we often got a shock as there quite big bangs from the quarrying.
