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?

Yes, I agree. What I was mainly saying was the lack of continuing the
red arrows beyond Platform 8 was the reason why I didn't think
departures would be happening via the platform ends.

I'm wondering how this will all work in practice, the report goes into a
lot of detail about what happens if it rains. Will we really see crowds
of people huddling outside (under a canopy or otherwise) waiting to see
if their train is going from platform 1 or 5, before they cross the
gateline? Or will they head for the area near the platform 8 buffers. I
have particularly in mind those few Cambridge train that depart from the
main shed just to confuse everyone. Later, they may go via SPILL, of
course.
