'Waterloo' eventually became 'Wimbledon'. Dartford was resignalled, but

This is the sort of thing I was thinking of - the BR SR 13 plan for
Ashford was not the same as the new Ashford that is today,

In
terms of passenger-miles, the majority of the former Southern Region is
probably controlled by about a dozen or so control centres.

Yes and no - there are approaching that number of large panel/IECC
boxes
Waterloo/Wimbledon
Feltham
Woking
Basingstoke
Eastleigh
Portsmouth (haha)
Victoria
Three Bridges
London Bridge
Dartford
Ashford
= 11,
but the point about the SR 13 is they would have eliminated *all*
other boxes, and clearly there are still a large number of those all
over the present southern zone. So today instead of 13 large area
boxes and nothing else, we appear to have 11 larg-ish area boxes plus
quite a lot of other installations, some of which looking as if they
will run on for ever.
