This got me thinking,
are there any level crossings on the London Underground
(surface lines, obviously). National Rail also have barrow
crossings and pedestrian footpath (and at least one shared
footpath/cyclepath) crossings at rail level but is there
anything similar on the L.U. (including shared Nat. Rail
sections)?

There was one on the Ongar branch, at North Weald station. The road
was only a farm track but the manually opperated gates were
interlocked with the semaphore signalling for the passing loop.
Because of this crossing I have heard it was still necessary to man
the North Weald signal-box for quite some time after the passing loop
was taken out of use (from memory, autumn 1976) - for some reason the
signalling could not immediately be switched out or decommissioned.

Other level crossings on the Loughton/Epping branch were replaced with
flyovers or underpasses, presumably in the 1950s.
