Rebuilding the 'sub surface railway' track and formation to mainline

Genuinely? About bloody time if they are.

Talking of such, I note that there is new continuously welded bullhead
rail in Euston Square station - never seen that before!

I thought long welded rail (300M lengths ISTR) was normal practice for
years before flat bottomed rail became standard on LU.

Concrete, surely?

Did Jarrah wood go out of fashion?

It was only ever used in tube tunnels, wasn;t it?

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.

Picture the scene: First train after resignalling gets to Harrow South
Junction or Mantles Wood and the ATP equipment picks up a "foreign"
signal that it doesn't understand and decides to sit down and sulk.

Cheers,

Barry

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)?

Yes, of course the new system is being fitted to the whole SSL.

Indeed so, but the original Metronet plan was to use a different system
to that planned by Tubelines for the Northern, Picc and Jubilee lines.
Given that the Picc shares tracks with the Met and District, this could
have caused real chaos at Ealing Common and Rayner's lane, as well as
round Wembley Park.

Hadn't they notice that the picc and met share the same track between
rayners lane and uxbridge?

Why are they chopping down the trees?



STEAM! Back in the days of old when steam ran, the heat and exhaust used to
keep any trees at bay and preventing them from encroaching too close to the
railway (with of course the odd fire thrown in)
However, as mentioned, since those days are long gone (electrification) the
trees themselves have pretty much grown as they wanted. They also cut them
down when they need to do bank stabilisation works.

Of course they had. The plan was (I think) to have both systems
installed on the track. As long as each one knows where all of the
trains on the section are, there's no problem.

As far as I know, no new contract has been awarded, so it could still
go to a contractor who uses a different system to the Piccadilly
(which will likely get Alcatel S40 - the same as Jubilee (being
installed), Northern (planned) and DLR (in use for years) - due to
being controlled by Tube Lines.

I would imagine that there's now a very high probability that the SSL
will share the same signalling system as the JNP lines.
