Similarly, London Bridge to Canon Street & Blackfriars - ish.

I'd included the latter in my original comment about south London, most of
the ex-SR terminals are fed by an elevated system.

London Bridge to Greenwich was the first elevated railway in the world.
Colonel Landmann designed it - a ground level railway would have involved a
lot of level crossings, and a sub-surface line could probably not have been
built in the 1830s because of the high water table. Landmann intended for
the arches to be used as houses, but in the event most went to commercial
undertakings.
