I thought they gave up on moving block signalling to meet the 1999

other automatically driven trains? I thought not.
Yes, the moving block intention was dropped in favour of a more
convential track circuit based system by Westinghouse. For the
upgrades the proposals for Jubilee and Northern are based on Alcatel's
SELTRAC system and for the Victoria (and presumably SubSurface)
Westinghouse "Distance to Go".

As Paul C says, no contract has yet been signed between Tubelines and
any suppliers for signalling and trains on the Picc line.
