No. Metronet had a projected overspend of GBP2bn *by 2010* (whereas
the TL cost rise is to 2015). But it went bust because it had
*already* overspent by GBP500m, and the PPP Arbiter refused to pass
the overspend onto London Underground. Hence the shareholders would
have needed to put in more equity to keep the company solvent, and
they decided not to.

I don't agree that they went bust because of the difference between
Metronet's cost overuns to date and the assessors figure.

Well, you're wrong.

Anyway how does that have any relevance to comparing Metronets future
oversend of £2bn for work on 5 lines verses Tubelines predicted future
overspend on work on 3 lines.

Because one was for the next three years, whereas the other is for the
following seven years.

Tubelines are so supposed to be super efficient and do all there jobs for
the estimated cost.

Which they largely have done, over the current period.
