So when did the data feeds for the lines that do have them get put in place?
As I said in another post , the northern line had these installed back in
the 80s. Was a major feed install done then?

I'm really no expert on signalling, but the sub-surface lines are way behind
everything else - bits of it are prehistoric. The fact this has only started

shown by successive governments of different hues (and then when the Labour
government finally decided it had to be addressed, they did so through the
flawed vehicle of the Tube PPP).
