of the bigger changes relates to Bombardier and the SSL upgrade.
Bombardier will produce the SSL trains but the related signalling

Sounds pretty accurate. The Bombardier PR implies that the SSL
contract will be re-awarded to Westinghouse, cutting out Bombardier as
middleman, but Invensys (Westinghouse's parent) confirms that that's
just the work to make S-stock work with the existing signalling; the
new signalling contract will indeed be retendered:

Does this mean that there's now a chance that the Thales (ex-Alcatel)
Seltrac signalling system that Tube Lines are installing could also be used
on SSL? It would at least avoid problems on the areas where the Piccadilly
shares tracks with the Met and District.
