I noticed today what appeared to be new connections from the fast lines

Anyone know what is going on? Are the connections permanent, are they
re modelling the junction?

The junction is being remodelled, mainly to remove the moveable angles
in the fast/slow convergence and to replace otherwise worn-out track
and pointwork.
