I don't think it would be that bad actually, provided you don't get WLL
and ELL trains arriving at the same time - will the track layout even
allow that?

There will be some simultaneous movements possible, because incoming ELL/SLL
trains will run past the existing stopping point to a new platform extended
out to the current centre track of 3. The new platform will then become P2,
the existing WLL platform will become a bay and be renumbered as P1.
(There are suggestions elsewhere that the whole island will also be extended
west by around 50m at the same time - this would allow for each platform to
deal with 6 car trains eventually.)

Another route down from the platform would be nice, and it could perhaps
be done with minimal disruption to the rest of the station if it just
drops down over the side of the viaduct.

The second set of stairs is to be reopened apparently, which will require a
rearrangement of the current gateline at the northern entrance. I wouldn't
be at all surprised if some or all of the current platform buildings get
demolished as well...

That isn't consistent with the reports that a Cambridge solution will be
adopted. For that to be the case there would need to be a new scissors
crossover halfway along platform 2 connecting to the through road.

Major redevelopment of Watford Junction has been on the cards for a
few years now, but seems to have stalled numerous times. Should really
all be rolled into the redevelopment of the Abbey line and the Croxley
link, but that would be joined up and sensible.

Sounds good. But what of the rotting, leaky platform level
infrastructure? One hopes they aren't just going to rebuild the
concourse and leave that as it is.

I have found a blog post here which gives more detail:
http://www.liverpoolchamberblog.org/...ound-stations/

"Full extent of the works at Liverpool Central is:

* Improved larger staff accommodation at the back of the station
* Installation of a new lift adjacent to the current lift at Liverpool
Central
* Replace escalators
* Relocate plant room to free up platform space
* Install platform edge gates
* Replace cladding
* Replace floor coverings
* Replace directional fire signage
* Relocate fire doors"

That's an extraordinary one, as it will require precise stopping by
the driver to get the carriage doors to align with the gates!

Gates are normally only deployed on automated systems, where the train
is brought to a stand by electronics. *Is this an early indication
that the new Merseyrail stock will have automated control?

I was under the imperssion the Jubilee Line Extension was run by
conventional driver-driving-the-train technology rather than something
more computerised, and they line up with the platform edge doors (that
seem to have a lot of tollerance in terms of the ratio of platform
door width to train door width).

IIRC the Jubilee Line has now switched over to an automatic system.
It was conventional for a long time despite the original intention
that it should be automatic.

OTOH it utilizes different technology than the Victoria Line.

is that still the case? *My understanding is that a new system has been
installed as part of the introduction of the 2009 stock. *It would make
sense for the various ATO systems on the underground to use the same system
(although that doesn't mean it is so).

According to Modern Railways 2011-07 page 71, the Victoria Line
utilizes DTG-R (Distance to Go Radio). The Jubilee Line, OTOH,
utilizes Seltrac S40 from Thales.

This shambles is a left over from PPP (Public Private Partnership)
interlude. So, down to Mr. G Brown. :-)

To be pedantic, ATO (Automatic Train Operation) is just one element of
an ATC (automatic train control) system. Which comprises ATP
(Automatic Train Protection), ATO and ATS (Automatic Train
Supervision) all of which are different between Vic Line and Jubilee
Line (and in fact the Central Line).

Thank you. This is a learning process.
