Yes, of course the new system is being fitted to the whole SSL.

Indeed so, but the original Metronet plan was to use a different system
to that planned by Tubelines for the Northern, Picc and Jubilee lines.
Given that the Picc shares tracks with the Met and District, this could
have caused real chaos at Ealing Common and Rayner's lane, as well as
round Wembley Park.

Hadn't they notice that the picc and met share the same track between
rayners lane and uxbridge?
