Surprisingly, the southern ends of the platforms are on a curve but
these will only be needed if and when we get 12 coaches. This curve
causes much flange noise from southbound trains to compete with
automatic train announcements.

This is because the station is superimposed on an existing track
layout with modifcations mainly in the vertical to provide clearance
to the overbridges.

IIRC the radius is around 200m on the Kings Cross curves. There is an
existing left and right hand reverse of similar size curves between
KXT and the new station.
