No problem; I actually forgot to reference your diagram in my reply- I have now gone back to add that info.

a) approach release of a signal for a slow speed diverging route,
b) modified aspect sequence utilised where signals on a line have to be positioned closer than considerations of braking distance would dictate and thus a "modified aspect sequence" is provided- which does involve approach release
c) the "delayed yellow" of a warning class route due to the Restricted Overlap beyond the following signal- which again involves approach release.
