In other words, when LU puts the Bakerloo contract out to tender,
Bombardier will be favourite to win it with something pretty similar
to the S-stock for the reasons you list (ie it'll be cheaper for
them to build and maintain the trains), and if someone else wins
that's because they want to offer us an even better deal that
outweighs the economies of scale.

Hopefully, Bombardier's Bakerloo bid will be based on the 2009, not
the S stock!

Haha, yes, fail.

However, they won't be able to just offer more 2009 stock. For one
thing, I think the 2009 stock is too big for the Bakerloo and Picc
tunnels, so even if Bombardier's bid(s) for these lines look like the
2009 stock, they'll actually be slightly smaller.

True, or at least "true so 'tis claimed". I imagine that squishing a
2009-stock to fit the Bakerloo loading gauge and adjusting the
equipment used to produce the 2009 stock to produce the squished stock
would be significantly easier than designing a Tube gauge train and
setting up a production line from scratch, though.

Indeed, and I bet they had this in mind when designing the 2009 stock.
After all, they must have thought they had the Bakerloo order in the bag
until Metronet collapsed.


OTOH, Alstom still has the ability to produce 1995/96 stock
bodyshells, as it did so a couple of years ago, the 1995 stock uses
modern IGBT traction and meets RVAR, and Alstom does the maintenance
contract on it - so they ought to be able to put up a reasonably
competitive bid.

Yes, it seems very likely that any Alstom bid would indeed be based on
the 1995/6 stock. It produced complete new trains and carriages for the
recent Jubilee lengthening project, which went very smoothly (I hope it
does as well with the similar Pendo project). That's why I mentioned
them, and not Siemens, Hitachi, etc, who may also want to bid for the
next big LUL order.
