With the tale of the LWT lines going over Waterloo and Blackfriars Bridges, plus technical advances and studios going out of business over the years, it also made me wonder how much redundant TV cabling there is below the streets of London...
I'd have thought that any from that era would have been long replaced by fibre. Space in the various ducts and infrastructure is limited, it will gave got to the stage when BT don't need to look up which circuits are redundant because all of a particular type of cable is obsolete - it'll just all get taken out.
These days a lot of connectivity is just leased bandwidth, it can be used for other things when one customer stops using it. Also its not necessarily a point to point circuit, there'll be a whole load of fibres past
TLS, of which they'll be just one user of
Going back to Thames and LWT however, the termination points for Thames' circuits were still in some bays at BT Tower in 2000:

Incidently, the circuits labelled TFS were Teddington and BHM were Central
