Subterranea Britannica one-day conference

Thought this might be of interest to this community as it's London and underground, if not London Underground:

Sub Brit has a mix of people interested in all aspects of man's use of natural or artificial underground spaces - with a slight bias towards the Cold War and (mostly disused) railway infrastructure.

Nothing on LU at this year's conference but there is a talk on the Berlin U-Bahn.
