I dont remember the exact details, but had the information at the time from someone involved in the discussion.
The deal was struck (if it was ever signed) at a time when ntl in South Wales were called ntl but were in fact CableTel, It was around the period that CableTel bought ntl but before they bought any of the CWC/Comcasts/Diamond mob etc.
I believe that CableTel/ntl buying up most of the opposition early on had a big impact on the overall availability of cable in the UK.

As I say I'm into Power Tx, Wessex Southern, DC 750v, 3rd rail.
Our S/stn are every 3 miles our rect. put our 300Hz, S&T use various Freq.
It was an small example of the the unfriendly electronic environment.
Deal must have been in the Railtrack days, kept being told against our licence to sell cable space, but diversity of routes with a massive handling capability (overground)must have be a money maker, if we still had a in-house IT group.
It been a good xmas, no bodies/fatalities, odd car turning left on X-ing, and no tripping so far this shift
