It really needs the buffer stops for platforms 11 & 12 moving down to
create a wider pedestrian route, if the current rolling stock can fit into
a shorter platform.

There is to be an array of ticket gates across P12, at an angle and just
past the new 'taxi' escalators and the lifts. The intention is then to have
a barrier along the length of P12, about 2m back from the platform edge and
as far as the new barrier line. At the end of last week the new barrier
line was present but you could walk round the end of it on the platform
side.

This is also shown in the planning drawings for the taxi deck and associated
work packages..

I agree with the idea of moving the buffer stops to give a larger
circulation area though - but as you say this would be highly dependent on
the max train lengths used in P12.
