I came across this historic image on Twitter, showing the just-built DLR
viaduct crossing the derelict docks at Canary Wharf, before the skyscrapers
were parachuted in. The absense of trains suggests that the pic was taken
in 1986 or 87.

Now, of course, the left of those three docks contains the future Crossrail
station, the centre has the Jubilee station and the third one still is
still full of water.

The undeveloped Greenwich Peninsula is also interesting.
