You're good at this.
The clues work exceptionally well if you happen to have a copy of a book called The Phoenix Suburb.
Which a very good book about history of The Crystal Palace, it's fiery demise, and the re-generation of the surrounding area.
I'd recommend it. I think you'd probably enjoy it.
Hilltop, disused railway (no bridges, but a couple of tunnels) John Logie Baird's experiments in the 30's and the present day transmitter - it's all there.
But my brain kept telling me your picture of the bridge was wrong for CP.
Were you looking around Crystal Palace? The clues work pretty well for there too, although as it wasn't really rebuilt I don't think it is phoenix like.
