I'm impressed that you seem to know what platform a train will
arrive at Kings Cross - the station announcers often don't,
until a few minutes beforehand.

Well every train has a particular booked platform in the full
timetable (differing public editions of the timetable info may not
show this data though). Things may get swapped around last minute some
days but that should only be when things are going wrong and
departures are late.

There used to be a monitor a little way down one of the platforms that
was for the station staff that showed the anticipated platform, ages
before (30-60 mins) the public display did, I always used to wander
over and check it out - but I think they took it away now.

Pretty sure they just choose not to announce it at KX until the last
minute to avoid mad dashes of departing passengers or huge crowds of
meeters and greeters.
