Perhaps they improved the clearances while they were at it and these
restrictions no longer apply. "

Whilst work may have happened on the southern end of the new
Thameslink station box at St Pancras, where the track is relatively
straight, I am not aware of any work on the reverse curves (the
Hotel Curves) between KX Thameslink and the new station box. These
are, I believe, the main constriant to the route clearances.

I think it's Midland Curve. Hotel Curve is the GN connection now
abandoned. IIRC the main constraints were in the GN rather than the
Midland tunnels.

BTW how do you improve clearances in a brick tunnel under a
builidng,?

With difficulty?
