Are they also planning to upgrade signalling system on the
Metropolitan line?

Long story... Metronet was planning to, but the contract was cancelled
after it went bust. It's still likely to happen, but a few more years
into the future, and using a different system (thank goodness!). TfL
isn't exactly flush with investment funds thse days.

The fun bit will be if the proposed ATP system (originally proposed to
be the latest revision of SELCAB, I believe) *isn't* backwards
compatible with that fitted to the Chiltern Railways fleet.

Wouldn't this new system have to be fitted not just to the met but the
H&C, circle and district too if they want the S stock to be interchangable
on all lines? Or will we be back to the old situation of certain trains only
being able to run on certain lines because someone in times past had bugger
all common sense (A stock being too wide for parts of the district line for
example)?
