the main concourse is at ground level, and the main entry/exit
from the platforms will still be directly from the existing front of the
station, towards the new square, and also via the western side concourse,
which will clearly provide much improved access to the underground. There
will also be a mezzanine level for cafes & shops etc.

Unfortunately there isn't a small size report I can link to, but its all
on
the Camden site if you slog through it...

I'm sure that last time I looked the platform ends were going to be *only*
exits [1]. I printed it out when this last came up, but that's at home 300
miles away. Later this weekend, maybe...

Found it at last. An Arup report for Network Rail "Station Design and
Passenger Movements, dated July 2006, Job Number 118944/03.

I can find no trace of this online at the moment.

That's the one, buried in the Camden sight as I suggested.

I agree that the text does say that departing passengers will go via both
the gateline and the bridge from the [western] Mezzanine, but all the
several passenger-flow diagrams in the report only show departures for
Platforms 1-7 via the bridge.

I think you are possibly misinterpreting this. If you look at the diagram on
page 5 (repeated as fig 1 on page 10) for instance, I'm taking the red
arrows to be pax arriving at the station [to catch a train] and blue as
departing [having arrived on a train]. If so the thick red arrows from the
'southern circulation area' are what we would describe as 'departures', and
are drawn proportionately, although it might have been clearer if they had
carried on to the individual platforms?

Part of the problem is that it seems you won't be able to access the
circulating area at the platform ends until *after* going through a
gateline (at which point you are cut off from the Mezzanine facilities).
So it's more likely that people with day-tickets will wait within the
Mezzanine area until their train is given a platform number and they start
to board.

Thats how I understand it for those type of pax, but its much the same as eg
Euston, Liverpool St, and shortly Waterloo, and IIRC at KX pax are held
queuing in the existing concourse for peak/busy long distance trains anyway.
Of course as you mention in another post, daily commuters will expect to
speed straight past all this, clutching their seasons.

All the major stations seem to be becoming more like airports, and the use
of gatelines, and not announcing platform details until shortly before
departure, retains pax in the concourse. Even little Marylebone has gone
very much this way...
