Have any external changes been made to the KX Thameslink station, (the
fascia for instance) to reflect its new LU only role?

The big 'King's Cross Thameslink' sign at the front has been removed,
and several square-shaped plastic sheets (with the blue/red Underground
roundel on a white background) have been placed along the glass wall and
perpendicular to the side of the roof as well.

Come of think of it, there are also blue 'KING'S CROSS ST. PANCRAS
STATION' signs just above the doors and (unsurprisingly) plenty of
notices stating that FCC now stop at StP instead.

That said, someone did ask me 'are the trains on strike?' when they saw
that the Thameslink platforms were closed off (we were beside the metal
gate next to Platform A at the time). I sent him to StP, and later on
suddenly wondered if he was actually looking for the tube.
